Well KL-15 | Reinforced concrete products from GK Blok
Elements of concrete wells The working chambers of KL-15 sewer wells are prefabricated reinforced concrete structures, consisting of various reinforced concrete elements and designed for engineering and drainage communications, various communication networks and sewer septic tanks. Concrete wells are universal for the construction of necks and trunks of prefabricated wells, which are joined by welding brackets.
Reinforced concrete wells are popular in private buildings and in areas where water supply systems, drinking wells and small sewers are built from them. Road construction also actively uses this type of reinforced concrete products. A concrete ring, together with a well cover and a bottom corresponding to the diameter of the well common to all elements, constitute a complete structure. To the elements of the wells, the working chambers of the KL-15 sewer wells are subject to strict quality requirements prescribed in GOST 8020-90.
The design of the elements of the wells, the working chambers of the KL-15 sewer wells is quite simple and is a frame made of metal reinforcement 6-10 mm thick, covered with concrete and having the required shape. The production process is mainly carried out by vibrocompression. The steel reinforcement cage is covered with a layer of heavy concrete and subjected to vibration, which gives the concrete the required density. The result is durable elements for high quality reinforced concrete wells with a thickness of 60-140 mm. In the production of elements of reinforced concrete wells, heavy concrete grades from M200 to M500 are used, which guarantees a margin of safety and crack resistance. nine0003
Our company performs assembly and installation of working chambers of sewer wells KL-15. For installation of reinforced concrete wells and elements of wells, please call (812) 336-87-96.
The main requirements for concrete for wells are strength, density and water tightness (W4), since concrete wells are buried below the groundwater level. Elements of the working chambers of KL-15 sewer wells have low water absorption and can interact with liquids for a long time. To use these elements in aggressive soils, special sulfate-resistant or other cements are used in production that tolerate reactive or chemical environments well. nine0003
Since the wells are deep in the ground and do not experience sudden temperature changes, the requirements for frost resistance of the elements of reinforced concrete wells, the working chambers of KL-15 sewer wells are calculated individually and depend on the climatic conditions of the installation site.
Designed to withstand loads from the cover and each other, the elements of the wells, the working chambers of the KL-15 sewer wells, are reinforced with frames made of hardened steel of the At-IIIC and At-IVC and A-I, A-II and A-III classes. Metal parts, especially external ones, are pre-treated with anti-corrosion compounds. nine0003

In our sales department, you can find out in advance to clarify the price from the group «reinforced concrete wells» and calculate the total cost of the order.
Installation of elements of reinforced concrete manholes
The size of the element is selected depending on the purpose of the reinforced concrete manhole being constructed. The diameter of the elements of the wells of the working chambers of the KL-15 sewer wells must correspond to the diameter of the working chamber. Sewer wells and rings are wider than water and gas pipelines. And if the wells will be used for intra-quarter networks, then it should be borne in mind that such pipelines are much narrower. nine0003
Manholes made of concrete elements Working chambers of KL-15 sewer manholes are mounted much easier and faster than other types. So that during installation they do not move out of place, the products are fastened together in four or six places with steel brackets.
For ease of use, the elements of the wells provide a place for installing a gate, a metal ladder or hanging brackets. The brackets are installed in the holes, and the hanging ones are laid at the docking points. Road construction will use the installation of products working chambers of sewer wells KL-15 on a cement mortar of a standard composition of 1: 2. The joints of the elements on all sides are rubbed with this composition and ironed. But even this does not exclude the waterproofing of wells after installation. nine0003
Indicators of acceptance testing of elements of concrete wells working chambers of sewer wells KL-15
- Concrete class in terms of strength and tempering strength of concrete;
- Compliance with reinforcing and embedded products;
- Strength of welded joints;
- Concrete cover thickness to reinforcement;
- Geometric accuracy;
- Concrete surface quality.
The technical passport accompanying a batch of elements of concrete wells, working chambers of KL-15 sewer wells, must contain information on the date of manufacture of the batch, on the number of products, on the results of strength tests, information on the brand of concrete, compressive strength, concrete frost resistance class and waterproof. nine0003
Quality control of elements of manholes working chambers of KL-15 sewer manholes reinforced concrete
As in other reinforced concrete products, there should be no cracks in the working chambers of sewer manholes KL-15. Only barely noticeable to the eye, so-called shrinkage cracks with a width of not more than one tenth of a millimeter, are possible. Minor deviations of the geometric parameters of the rings are possible, not more than ± 5 mm in thickness, ± 6 mm in the diameter of the reinforced concrete product. The surfaces of the product should not have a large number of shells with a diameter of more than 15 mm and a depth of more than 5 mm. Ready-made reinforced concrete wells should not hide the mounting loops of the elements behind the influx of concrete, as this may complicate the installation of parapet slabs. nine0003
Storage and transportation of concrete manhole elements
Concrete manhole elements Working chambers of KL-15 sewer manholes must be stored in stacks in working position, face up. One stack should not consist of more than 3-5 rows, in order to avoid falling and deformation of reinforced concrete products. For delivery, the products are stacked in a stack no higher than 2.5 meters and securely fastened. During transportation and storage between the elements there must be gaskets with a thickness of at least 40 mm. nine0003
BLOCK Group of Companies carries out
delivery of power transmission towers throughout Russia
directly to the customer’s site or to the construction site, if the infrastructure allows.
The working chamber KL-15 is a monolithic structure, which is used in the arrangement of gas, water, drainage and sewer systems. The well allows access to engineering communications, and also simplifies the process of maintenance and repair work. nine0003
Since the structure is located underground, the well must withstand heavy loads, protect communications from corrosion, temperature extremes and aggressive environmental influences. That is why, in the manufacture of unified wells, heavy concrete of class B15 (M200) with a high density and a reinforcing mesh up to 1 mm thick are used.
Working chambers (wells) are used when installing communications and facilitating access to engineering systems during repair and maintenance work. In addition, they can perform the function of connecting pressure pipelines located at different depths and help change the operating modes of pipelines. nine0003
Varieties of wells
- VS and KL — used in the arrangement of drains and storm sewers. The design is a pipe with a bottom and two side holes.
- VG — used in the arrangement of water and gas systems and serve as a working chamber. The design is a pipe with a bottom, without side holes.
- VD — used for receiving, accumulating, pumping and distributing wastewater, used in residential and industrial facilities. The well is characterized by increased tightness and frost resistance, withstands any weather conditions. The design is a pipe with a bottom and two side holes. nine0042
For example, take the working chamber of the well KL-10 , where:
- KL — the working chamber of the sewer well
- 10 — internal diameter of the well in decimeters
The well has the shape of a cylinder, consists of several additional rings, is completed with a bottom, gratings and hatches, depending on the installation location of the structure. Light hatches are used in pedestrian areas and parks, heavy hatches are used on the carriageway and roads. nine0003
To avoid flooding of roads during rains, a storm drainage system is installed, including a storm water inlet. It is attached to the well using a frame, which is rolled up with asphalt or cement mortar.
Manufacture of well chambers uses not only high-quality materials, but also the latest center-figuring technology.
The well frame is fixed in a centrifuge and the concrete mixture is distributed using a concrete distributor. After that, the product undergoes heat treatment. This manufacturing method makes unified wells resistant to corrosion and chemically active processes. nine0003
Reinforced concrete wells are the most demanded products in the arrangement and laying of various communications.
The main advantages of these products include versatility, strength, durability, tightness and affordable price.
Wells are capable of protecting engineering systems from negative environmental influences for a long time: they are not subject to corrosion, temperature changes, chemical attack and do not absorb foreign odors. nine0003
Products are an important component in the installation of drainage structures, water channels and utilities.
