Major repairs of the garbage chute. Experts' comments

Using a garbage chute has become one of the usual amenities of living in a city apartment building. Thanks to the presence of a garbage chute, removing household waste from the apartment is completely easy and not burdensome. Any family member can go lightly into the staircase-elevator hall or onto the landing and drop a bag of garbage into the loading valve of the garbage chute.

A properly constructed and properly operated garbage disposal is a real assistant in housekeeping, and not a source of problems and unpleasant experiences. Simply, it must be kept in good condition and clean. How to keep them in good condition and clean plumbing fixtures located inside the apartment: sinks, bathtubs and other more delicate devices.

Unfortunately, the state of residential garbage chutes apartment buildings often leaves much to be desired. This is caused by a violation of the rules for operating the garbage chute, but most often by the expiration of its service life. No matter how you smear paint on the barrel and valve, no matter how you weld the hinges of the bucket, if the equipment of the garbage chute has served its purpose, then it needs to be completely replaced.

Thus, the standard operating life of the garbage chute loading valve is 15,000 cycles. It turns out that if the residents of four apartments use it once a day, that translates into a ten-year term. When the garbage chute loading hatch is placed on interfloor landings across the floor, the number of apartments it serves increases to 8, and its service life, accordingly, decreases to 5-6 years.

The wear rate of garbage chute equipment designed for disposal of solid household waste increases if it is not used properly.

One of the functions of a garbage chute valve is to calibrate the waste discharged into the garbage chute. The valve bucket volume is 12-18 liters. Attempts to stuff larger bags, bulky packaging, etc. into the garbage chute. lead to damage to the waste collection valve and blockages in the waste chute.

Violations of the rules for operating a garbage chute also include the removal of liquid waste, which causes premature corrosion of the metal bucket.

If damage attachments garbage chute can be eliminated by repairing the garbage chute bucket, repairing the garbage chute valve, repairing the garbage chute hatch seals, and so on, then a garbage chute barrel that has become unusable can be restored only by completely replacing it with a new one. Moreover, asbestos-cement pipes, previously used for the construction of garbage chutes, have not been used for these purposes for 15 years and must be replaced when repairing garbage chutes in Moscow and other cities.

Asbestos-cement pipes, which were hygroscopic and assembled with cracks and rough joints, were replaced by mass-produced sandwich-type garbage chute pipes with an inner layer of stainless steel. This garbage disposal looks nice and will last a long time. In addition, it can now be regularly washed and treated with a liquid disinfectant solution using appropriate washing units located on the garbage chute on the technical floor of the house (or, in its absence, on the residential floor, above the loading valve).

The faulty condition of the garbage chute of an apartment building, caused by its damage and excessive operation without timely repairs, really becomes a headache for all residents of the building.

The scale of the problem can be judged by reports of a faulty garbage chute received on the portal of Moscow Mayor S.S. Sobyanin. Moscow Our City http://gorod.mos.ru/, numbering in the hundreds.

An unpleasant smell, unsanitary conditions, an unkempt appearance - all this can easily spoil the mood of even the most inveterate optimist and serves as “indications” for immediate repair of the garbage chute at the entrance.

TO cosmetic repairs garbage chute in Moscow includes the restoration and repair of the garbage chute valve bucket by replacing it along with the hinges. Where this cannot be done, a new garbage chute hatch is welded onto the old hinged valve body through an overhead frame.

Replacing the valve bucket seals is also a cosmetic repair.

Of course, completely replacing the garbage chute valve is more effective, but it is not always possible due to the partial blocking of the old garbage chute at the valve location.

Under the garbage chute overhaul program, Moscow will completely replace garbage chutes in residential buildings Built in the 70s and 80s, included in this program. The garbage chute barrel, loading valves, garbage chute gate, garbage container, and garbage chute ventilation unit must be dismantled and replaced. You can find out when the overhaul of a particular house will take place on the Internet resource https://www.reformagkh.ru

From the point of view of organizing and carrying out work on the overhaul of the garbage chute at the entrance, the greatest difficulty is the re-equipment of the garbage collection chamber.

The concrete cabinets placed in them with an inclined surface on which garbage from the garbage chute is dumped do not comply modern technology removal of solid waste directly into a container on wheels and serve as sources of unsanitary conditions. Even looking into these old designed and constructed garbage chambers of residential buildings is dangerous for particularly sensitive passers-by. In accordance with the set of rules SP 31-108-2002 Garbage chutes for residential and public buildings and structures “the presence of intermediate devices for manual transfer of solid waste from the shaft to the container is not allowed.”

After dismantling such cabinets, a modern gate with an automatic smoke cut-off system in case of fire and a non-replaceable container are placed in the garbage chambers. Cosmetic repairs of the garbage chute bucket and valve and major repairs of the garbage chute in apartment building in general will be effective if replacement is used quality equipment famous manufacturer and an experienced company will be involved in the repair.

LLC "M. ENGINEERING COMPANY, which is both a supplier of garbage chute equipment and an installation organization, has accumulated vast experience over 20 years of work in this field, which takes into account the variety of modifications in the design of garbage chutes, their various placements inside a residential building and the practice of constructing and repairing garbage chutes in Moscow.

Installation and reconstruction of waste disposal systems
Problems and solutions

A. V. Samoilov, CEO PRANA LLC

This publication continues a series of articles devoted to the problems of equipping residential buildings with waste disposal systems. The article will discuss the features of various designs of these systems, as well as the problems that arise during their reconstruction. The latter circumstance has now acquired particular relevance in the light of the implementation of the capital repair program for buildings. The article analyzes the most typical problems (selection of the most advanced systems from a design point of view, their correct operation, etc.) and discusses ways to solve them.

Currently, there is a debate among experts about whether it is generally necessary to install waste disposal systems in newly constructed and reconstructed buildings. Experience in operating systems since the days of widespread use of asbestos-cement shafts has shown that in some cases the already installed system is not used by residents, the loading valves of garbage chutes are sealed and the garbage is taken out in bags directly into containers. Experts rightly note that if the design of a garbage chute does not allow it to be kept in normal sanitary condition (which is inevitable when using asbestos cement pipes) or the maintenance service does not maintain the waste disposal system at the proper level, then it is better to do without a waste chute. Based on this and assuming that in one or another newly constructed residential building, due to the impossibility of ensuring compliance with sanitary and hygienic requirements, a garbage chute will not be used anyway, customers often decide to install a cheaper system only in order to pass the project examination stage and hand over the building is in operation. In this case, the loading valves are simply welded during construction and remain in this state after the building is put into operation. Residents of a new building, as a rule, put up with the absence of a garbage chute, getting used to it even during renovations in their apartments, when, according to regulations, the garbage chute is closed to prevent the dumping of construction waste.

A different situation is observed in the case of major renovation of a residential building. Residents who have been accustomed to using a garbage chute for many years (even if it does not meet all sanitary and hygienic requirements) are unlikely to refuse to use it after the renovation is completed.

Major renovation provides for the creation of more comfortable living conditions in exploited residential buildings. According to official data, in 2008, major renovations were carried out in 1,600 residential buildings in Moscow. At the same time, work was carried out in most of the buildings under the selective capital repair (SCR) program, which includes the replacement of water supply, heating, sewerage systems and, in some cases, electrical supply and elevator equipment. At the same time, instead of replacing the garbage chutes with a normal waste disposal system, they were only slightly updated, and only 10% of the buildings being renovated underwent a comprehensive overhaul (CCR), including the replacement of the old garbage chute with a waste disposal system.

Based on the condition of buildings repaired under the selective capital repair program, we can conclude the following. Usually, the lining of the entrance was changed, the walls and garbage chute were painted, and worn-out loading valves were replaced with others with approximately the same characteristics. Of course, the garbage chute acquired a more aesthetic appearance (which, however, as practice shows, does not last long), but the main problems associated with cleanliness were not solved inner surface trunk and lack of odor from it.

As a result, despite the fact that very significant funds were spent on the renovation of the building, if the old garbage chute was preserved, unpleasant odors still appeared in the entrance and an acceptable level of comfort was not achieved. It should be taken into account that the cost of a garbage chute is a very small fraction of the cost of the building. This issue has been repeatedly discussed among experts. Currently, in Moscow, all residential buildings are undergoing a comprehensive overhaul program, and projects must include a “Waste Disposal Systems” section, which is accompanied by a detailed drawing of the system and cost estimate.

During the implementation of the repair program, new problems were discovered. In particular, despite the fact that the project includes a complete replacement of the worn-out waste disposal system, in practice this is not always carried out. If technical inspection shows that, for example, the wear of the system is 25%, the garbage chute barrel is not broken and only half of the loading valves are rusted and skewed, then only the loading valves are changed.

Budget sequestration required not only a reduction in the number of buildings being repaired, but also a prioritization of repairs. Thus, from the planned volume, it was decided to leave the repair of heating and sewerage systems and insulation of facades, and to postpone the repair of garbage chutes to a subsequent period. The approach implemented in one of the Russian cities seems more correct. There it was initially planned to repair 900 buildings, however, taking into account the actual number of well-established contractors, material and time capabilities, only about 250 buildings were repaired, but in full and at a high level.

Constructive decisions

If we talk about the technical side of the issue, there are quite a few problems revealed by checking the technical solutions included in modern designs of waste disposal systems. At the moment, garbage chutes made of asbestos cement are still widespread. This is, of course, the most economical option. However, its multiple disadvantages are well known: it has rough surface, is hygroscopic and, therefore, accumulates a variety of debris well on its walls. In addition, this is a favorable environment for the appearance of household insects and rodents. As noted, such trunks are often left in buildings being renovated, but in many regions of Russia they continue to be used in new buildings. An asbestos-cement shaft that has served for 20 years or more cannot be properly washed. Research reveals situations that have not yet found an acceptable explanation: a sample a month after disinfection gives bacteria than the sample before cleaning. In Moscow, the Moscow region and a number of other regions, asbestos-cement waste chutes have not been used for about 10 years, and this required considerable effort on the part of many interested specialists. Currently, it is understood that the barrel should be made of steel, either stainless, or, according to one of the new technologies, galvanized with a special polymer coating.

Currently, there are quite a large number of manufacturers of waste disposal systems. They all produce systems that differ significantly in their structural elements. Let's look at the main ones.

Garbage chute

The dominant barrel design is a three-layer sandwich barrel. Common conventional abbreviations are NSP or NST. Such a barrel consists of inner and outer steel surfaces, the space between which is filled with sound-insulating and fire-resistant material.

All these barrels differ primarily in the method of manufacturing the steel surfaces. In one case, sheet steel is used, which is rolled into a pipe and welded with one vertical sealed seam, which provides a smooth inner surface. In the second case, the trunk of the garbage chute is made of steel spiral tape using technologies used for the manufacture of air ducts. Such trunks are distinguished by greater manufacturability and low cost, but are more difficult to maintain clean during operation. The grooves at the seam are difficult to wash, over time they become clogged with dirt and facilitate the movement of household rodents and insects along the trunk.

The trunks differ in the methods of centering the outer and inner surfaces. More precisely, in some designs the concentricity of the surfaces is maintained with the help of various locking rings, while in others it is not observed at all. The result of the second option is the ellipse of the inner surface, which excludes its complete cleaning and washing, as well as the varying thickness of the walls (with an average thickness of 25 mm, for example, 10 mm on one side and 40 mm on the other), which sharply worsens the soundproofing properties of the barrel.

The thickness of the soundproofing layer also varies. Three main options: 10, 25, 40 mm.

Gate device

The use of gate devices is mandatory in the waste disposal system. Their main purpose is to block the trunk of the garbage chute during garbage removal, work in the garbage chamber (for example, its disinfection), as well as automatic fire cutoff - eliminating draft and preventing smoke from entering the barrel and onto the floors if a fire occurs in the garbage collection chamber.

The most common are two gate design options. In the first option, there are tight doors that are open during operation, and closed using a special lever when removing garbage. When ignited, they close automatically. This design is the simplest and safest.

The main element of the second option is a pendulum bowl weighing approximately 20 kg. When the waste disposal system is in working order, it rises and is secured to the wall with a latch. When a fire occurs, the pendulum, falling down, blocks the trunk of the garbage chute, but not tightly. And the most unpleasant thing is that it cannot be ruled out spontaneously when the latch fails. This is simply dangerous for service personnel. Therefore, in order to avoid injuries, such a structure is most often simply dismantled after some time.

Mechanism for cleaning, rinsing and disinfecting the barrel of a garbage chute Two common abbreviations are SPSP and ZUM. Along with a smooth-walled steel trunk, it is this device that allows you to maintain the entrance of a residential building in a sanitary safe condition, and therefore comply with the requirements

Federal Law

dated March 30, 1999 No. 52-FZ “On the sanitary and epidemiological welfare of the population.”

The instructions categorically do not allow maintenance personnel to come into contact with the barrel space; it requires irrigation of the inner surface hot water under pressure using a ring shower and much more.

The vast majority of manufacturers simply ignore all these requirements.

Loading valve

There are two problems with the choice of loading valve. The first is to ensure its tightness. In accordance with all standards, the valve bucket must have a tight fit to the barrel, but in practice it turns out that this requirement is hardly met, for example, the valve is not equipped with airtight gaskets. Less commonly, the loading valve is equipped with regular rubber or magnetic rubber, similar to that used to seal refrigerator doors. The latter option has proven itself to be the best because it allows for complete sealing of the loading valves. The second point concerns the dimensions of the loading valve bucket. On the one hand, it is preferable for residents to use a bucket, which allows them to throw out a larger volume of garbage at a time, and on the other, according to SP 31-108-2002 “Garbage chutes for residential and public buildings and structures,” inner dimensions the bucket (diagonally) should prevent loading into the barrel objects larger than 0.9 times the internal diameter of the barrel. The essence of the requirement is that a larger object can stand in front of the garbage chute and block the path of other garbage, creating a blockage. Currently, at least half of the loading valves produced do not meet this requirement, easily exceeding

open position

diagonally and 1.2 barrel diameters.

Choosing a waste disposal system

Let's consider how the choice of a waste disposal system should occur - be it a new building or a building undergoing major renovation. Firstly, there must be a system of “filters” that does not allow access to construction sites by systems that are unable to ensure that the entrances are kept in normal sanitary condition. To some extent, such a system exists in the country. There are the above-mentioned SP 31-108-2002, Instructions of the Chief Sanitary Doctor, regulatory requirements By

fire safety

Further. For each facility, be it a new building or a building undergoing major renovation, a project is developed that includes a section “Waste disposal system.” It is the design organization, at least in theory, that determines which system should be applied. From a common sense point of view, the designer must not only check for the availability of appropriate certificates, but also determine whether the system being incorporated into the project will be effective. In practice, it is rare that a designer is able to explain how one system differs from another, and designers most often do not know at all about such documents as the Instructions of the Chief Sanitary Doctor.

As a result, approximately 70% of capital repair projects of Moscow houses standard series involve the use of twisted barrels with a traumatic gate and an electric motor of a cleaning device located directly in the barrel.

And in cases where the binding standard solutions, developed by leading institutes, carried out by private workshops, you can find very strange results. A project for the overhaul of a 16-story building may include a specification for a waste disposal system for 9 floors. A barrel from one manufacturer may be installed, and a cleaning device from another, but they are absolutely incompatible, even just in terms of mounting dimensions!

All these projects successfully pass state examination.

Finally, the last, decisive stage - the general contractor decides which garbage chute to install. At this stage, everything is simplified to the limit.

The general contractor needs:

1. Install a garbage chute and hand it over to the operating organization. To do this, you need to present a set of relevant certificates and demonstrate that the cleaning device works, that is, the brush assembly moves up and down when the start button is pressed, and, as a maximum, the garbage collection valves do not leak when the water starts.

2. The most important thing is to spend as little money as possible on all this.

In most cases, the general contractor is not interested not only in how exactly the system is structured, why it is better or worse than others, but also in what kind of system is included in the project.

Of course, there are many exceptions. There are contractors who carefully select a specific design, there are those who comply with the requirements of the project, and if they want to replace the provided design, they re-coordinate it at the design institute.

But the main trend is visible very clearly - no one is interested in the quality, performance and environmental efficiency of waste disposal systems.

Our country has been living in conditions for almost two decades market economy. The main engine of such an economy is competition. However, normal competition involves lowering prices while improving quality.

So, in the market for waste disposal systems, competition is going differently - lowering prices due to lower quality. The impact of such competition on our living conditions is obvious.

The general contractor is not stopped by the provisions of the Civil Code and the Law on the Protection of Consumer Rights, according to which residents have the right, within five years after the house is put into operation, to make complaints about the quality of housing, including the waste disposal system, and demand that deficiencies be eliminated.

The position of the general contractor is simple: the apartment was purchased from the investor, if he has to satisfy the requirements for replacing the garbage chute, then he will bear the corresponding costs, because the contractor has provided all the necessary quality certificates.

All of the above applies equally to both new construction and major renovations. But there are also differences. If in new buildings, as mentioned at the beginning of the article, the operating organization often does not intend to operate the garbage chute at all, then during a major overhaul you cannot count on this.

In theory, it is in this case that the relevant DEZ or management companies involved in all stages of repair should be especially attentive to the quality of the garbage chute. In practice this does not happen very often.

There can be only two reasons for this state of affairs. 1. The operating organization considers the replacement of an old asbestos-cement garbage chute with a new garbage disposal system as just a replacement of a “pipe” and is not going to fully service it - first of all, use the cleaning, rinsing and disinfection mechanism. In this case, if the “pipe” is normal, then the residents will, of course, have a gain, but it will be small. 2. Those

Thus, it can be stated that in order for the overhaul of multi-storey residential buildings to bring tangible benefits to residents, in terms of both comfort and sanitary conditions, effect, necessary:

1. Replace the old garbage disposal with modern system waste removal.

2. Choose the right design for the waste disposal system.

3. Ensure the operation of the waste disposal system in accordance with the Instructions for cleaning, washing and disinfecting waste disposal systems of residential, administrative and public buildings.

Replacement of waste disposal systems

What is the process of replacing an old garbage chute with a garbage disposal system?

As a rule, no special technical difficulties arise.

It is necessary to dismantle the old asbestos-cement trunk, expand the holes in interfloor ceilings up to a diameter of 500 mm (the diameter of the trunks of most manufacturers is 432–465 mm) and install a new system. Depending on the availability and qualifications of personnel, the general contractor carrying out the overhaul carries out the installation on his own or engages a direct system manufacturer for this.

This process happens very quickly - a team of two installers installs a shaft in a 20-story building in just one working day.

Difficulties caused by the endless variety of designs of the existing housing stock, of course, arise.

There is an increased amount of work in the waste collection chamber when the old gate is lined with brick or filled with concrete.

An old garbage chute may actually be hanging in an elevator shaft, in which case it is necessary to install additional intermediate support structures.

There are also hopeless situations when the old garbage disposal is walled up in the wall, for example, in the case of garbage disposal valves in the kitchen. If there is enough space on the landing, then it is possible to install the system, but the costs increase significantly - you need to punch new holes in the interfloor ceilings. And if the site is cramped, then installing the system is impossible in principle.

In the vast majority of residential buildings, installing a new waste disposal system is possible and necessary.

Operation of waste disposal systems

The entire process of operating waste disposal systems is described in great detail in the repeatedly mentioned Instructions of the Chief Sanitary Doctor.

The main thing is that once a month the operation service specialist must activate the cleaning mechanism, “drive” the brush assembly along the barrel, removing debris from the internal walls of the garbage chute, rinse the barrel with hot water, fill the appropriate container with a disinfectant solution and irrigate with this solution inner space garbage chute.

Nothing complicated. But only a few management companies, mainly in luxury housing, do this.

To achieve widespread compliance with the Instructions, and consequently, compliance with the requirements of the Federal Law “On the Sanitary and Epidemiological Welfare of the Population” No. 52-FZ of March 30, 1999, is the direct task of the Rospotrebnadzor authorities. When all operating services fulfill their responsibilities, then real market competition will begin in the market for waste disposal systems - who would want to put into operation a system that cannot work!

The city target program for the overhaul of apartment buildings for 2008–2014 will operate for another five years. There is time to take into account the mistakes made and provide a huge number of Muscovites with normal living conditions from an environmental point of view. 

In southern countries, for example, Turkey, garbage chutes are not used at all due to climatic conditions. In fact, with the use of good waste disposal systems and their proper operation, it is quite possible to ensure their normal operation even in hot climates.

In Europe, where, as a rule, people try to live in low-rise buildings, garbage chutes are also not common. Foreign specialists are more interested in the problem of separate waste collection, which is being solved quite successfully, primarily thanks to the mentality of European citizens, which is characterized by increased discipline. At the same time, in our country there is a strong opinion that Russian people have a different mentality, who would never want to complicate their lives by separating garbage. Surveys, however, show that up to 75% of Muscovites are ready to participate in the separation of discarded household waste if appropriate conditions are created. And if we add to this a certain material interest, then the problem may well be solved.

A design has been developed that provides not only separation, but also primary processing of household waste directly at the entrance. Instead of garbage, recycled materials will be removed from the entrance in bagged form. The installation of such a structure in one of the new buildings in Moscow is currently being completed.

Major renovations in houses 2020

Dear residents of houses, as well as contractors!

Based on the regional program approved by the Fund for the Capital Repair of Apartment Buildings in Moscow, the Mikmont company provides a range of services and produces high-quality equipment for replacing garbage chutes. The equipment is supplied and installed in accordance with the design documentation.

Overhaul of the waste disposal system

As part of the common property of the intra-house waste disposal system, the following are subject to replacement and installation:

• Three-layer barrels Sandwich type made of galvanized or stainless steel

Attention: From the total flow of objects we completed under the “Capital Repair” program, it was revealed that, along with standard solutions, about 30 percent of the objects are houses with a specific architecture (50-80 years old). For such houses, the Mikmont company has developed special non-standard solutions to replace the garbage chute.

Non-standard solutions for replacing waste disposal systems in buildings built according to the norms and regulations of the 50-80s and having specific architectural features

The Mikmont company produces, supplies and replaces waste chutes under the capital repair program in residential apartment buildings and for Lately has the following work experience:

• Garbage chute replacements have been successfully completed in more than 400 homes under the Capital Improvement Program
• More than 1,200 waste disposal systems were professionally replaced under the Overhaul program

Mikmont is the only company on the market that has everything in stock existing types garbage disposal systems

The experience of replacing garbage chutes under the Capital Repair program at more than 400 sites has shown that in all apartment buildings built in the 50-80s, it is often IMPOSSIBLE to replace garbage chutes based on standard modern projects, due to the fact that these buildings were erected according to SNiPs of the 50-80s and their architecture differs from modern houses, for which they are mainly prescribed current SNiPs and JV on waste disposal. In this connection, for almost every facility under the “Capital Repair” program it is necessary to develop special technical solutions, some of them are given below:

Non-standard solution No. 1 - Cradle

Previously, buildings were erected synchronously with the garbage chute floor by floor - the lower end of the trunk was built deep into the wall and was a walled-up metal box with a door. Often such boxes are located at a height of 20-50 cm from the floor, as well as at a depth of up to 1.2 m in the wall. In this regard, installing a modern damper with a fire extinguishing system at a height of 1.20 - 1.40 m from the floor according to TSN 21-302-2000 is simply impossible. In such cases, service organizations draw up a request that the new camera be of the same type as the previous one. After all, it is simply impossible to break the ceiling or operate a new gate at a height of 50 cm from the floor and below. Based on such requests, the Mikmont company has developed a metal box with a door (“Cradle”), to which a new gate is welded for the construction of a modern garbage chute shaft.

Non-standard solution No. 2—Ceiling damper

Based on TSN 21-302-2000, it is customary to install the gate with a support guide pipe at a height of at least 1350 mm from the floor, while the height of the garbage chamber must be at least 2.2 m, and the angle of inclination of the pipe should not exceed 20 degrees. However, in the majority of houses participating in the “Capital Repair” program, waste disposal rooms have a height of 1800 mm or lower. Under such conditions, the gate will be located at a height of 1000 mm and below, which does not comply with TSN 21-302-2000 and other norms and regulations. Also this design will be inconvenient to use. For such cases, the Mikmont company has developed a special ceiling damper.

Non-standard solution No. 3— Garbage chute valve with “removal” (increased depth dimension)

This solution is used in houses where the waste chute is located in the elevator shaft and/or runs at a distance of more than 15 cm from the floor area. To ensure safe and convenient operation When discharging solid waste, Mikmont recommends installing waste chute valves with “removal”. This solution allows you to reduce the distance from the ceiling to the waste disposal system, as well as minimize further costs for contractors to perform additional lining of the shaft to eliminate the unsafe distance between the ceiling and the standard valve.

Non-standard solution No. 4— Garbage chute with a smaller diameter than the standard one

In some houses participating in the “Capital Repair” program, asbestos garbage chutes with a diameter of 300 - 320 mm or another diameter smaller than what is customary are installed in niches and shafts bordering elevators and apartments. modern standards. Sometimes it is not possible to expand the niches in the walls and enlarge the holes in the ceilings; in such cases, the Mikmont company produces sections of the garbage chute according to individual sketches.

Non-standard solution No. 5— Garbage chute trunk with a diameter larger than standard

Some houses participating in the "Capital Repair" program have asbestos waste chutes with a diameter of 600 mm or other larger than the standard diameter. In such cases, the Mikmont company manufactures waste chute sections, valves and pipes according to individual sketches.

Non-standard solution No. 6— Garbage chute located in the elevator shaft

Not all consumers (residents) like spirally wound garbage chutes, and due to the fact that for the installation of a section of the garbage chute located in the elevator shaft, a niche of no more than 50 cm is allocated on the side of the elevator shaft, and the valve on straight-seam shafts is mounted using a clamp connection, further maintenance and routine repairs of waste chute valves become difficult. The Mikmont company has developed a technology in which straight-seam sections of the garbage chute are connected using a shell, and the connection of the garbage chute valve to the barrel is made using self-tapping screws at the production stage, which solves all the above problems.

Loading valve - a mechanism that ensures the discharge of garbage into the trunk of a garbage chute on each floor of a high-rise building and the isolation of the premises of the staircase and elevator assembly from the internal cavity of the garbage chute. Just about ten years ago, these valves caused serious complaints and dissatisfaction among consumers, as they were bulky, inconvenient to use and often could not last even a relatively short warranty period. Manufacturers of garbage chutes and components for them (garbage chute valve, gate valve, etc.) were hundreds of enterprises throughout the Russian Federation. As a result, the designs of manufactured garbage chutes and their components are currently significantly different from each other, which makes garbage chute repair very problematic and expensive. In addition, many modifications of garbage chute loading valves are currently not produced at all, and in some residential buildings, in order to additionally eliminate odors from technical and household waste, the loading valves and garbage chute pipes were blocked with bricks. This excluded the possibility free access to the valve body for its removal in case of replacement.

To solve these problems, our company has introduced into mass production loading valve repair kits , allowing valve repairs to be carried out without dismantling the valve body and in cases where there is no access to the garbage chute pipe. For this purpose, the company produces a number of modifications repair kits (KM-380/300R, KM-600/400R, KM-250/200R) .
The design of the repair kit allows for the removal of the bucket without dismantling the entire body, which is very convenient when cleaning the garbage chute pipe or replacing the bucket or seal.
The design of the repair kit allows repair of loading valve buckets regardless of their design and the year the garbage chute was put into operation.
Installation (mounting) of a repair kit on the body of a faulty valve does not require special tool and can be performed by in-house specialists of the operating organization.

The new loading valves are made of 2 mm thick metal. Thanks to this they are resistant to corrosion. There are practically no welding joints in the design of the garbage disposal valve, this increases its service life. Instead, the manufacturing process uses a precision folding method. metal sheets. It was developed quite recently, but is already popular all over the world.

We will be happy to provide you with the opportunity to purchase the highest quality metal loading valves that are only produced in our country. Thus, you will protect the residents of your house from the stench and invasion of insects in the entrances, solve the problem of garbage disposal and win the favor of your clients.
