2. The main scope.

Rings of wells wall KS 15-9 are used as a basis for the construction of the underground part of the wells of various communications. Their use is expedient not only in industrial, but also in private construction. These products are the basis for the construction of small sewer and water, gas and manholes for various purposes. Complete with a bottom and a lid, the structure is a ready-made finished hermetic structure. Use in the sewer and plumbing system imposes special requirements on wells.

Main userings of wall wells KS 15-9 is the construction of water and sewer networks for various purposes. The convenience of using these products is that the rings are installed one on top of the other, and the joints are sealed with mortar. The lifting of the product is carried out by the loops mounted in the process of manufacturing the ring. This reduces the time for building a well to a minimum, and a person little familiar with construction can do such work. During the construction of the wellCOP 15-9 brackets or a ladder are mounted in the walls or at the joints of the rings for ease of descent and ascent.

3. Designation of product marking.

Marking well reinforced concrete rings KS 15-9 carried out in accordance withGOST 8020-90 , as well as Series 3.900-3 . The letter group KS - wall rings, product type designation, 15-9 - internal diameter and height of the product, the water resistance of concrete can also be indicated (N - normal, P - reduced, O - especially low). Additional letters may indicate:

2. b - 4 holes.

The main overall dimensions are the following parameters:1680x1680x890 , where the outer and inner diameters, height are respectively indicated. The mass of products is1000 . Geometric volume -2,5119 , the volume of concrete per one product -0,4 .

Markings, weight and date of issue are applied to the outer side surface with indelible black paint. Additionally, the manufacturer's trademark is indicated.

4.Basic materials for manufacturing and characteristics.

make wall well rings KS 15-9 vibrocompression method. This gives the product the necessary strength and mechanical rigidity. The operation of the product below the groundwater level imposes special requirements on them for water tightness - a grade of at least W4. The use of sulfate-resistant cements provides resistance to the aggressive effects of groundwater.

Main materialwall rings KS 15-9 - heavy concrete grade for compressive strength M200-M500. A metal welded mesh of reinforcement is inserted into the mold and poured with concrete. Then, for hardening, the mold is subjected to vibration in order to achieve the necessary strength of the product. One of the requirements for finished product, is water resistance, since the installation of rings in most cases occurs below the groundwater level. In the production process, special attention is paid to the observance of the dimensions of the products, which is important in the construction of wells with the correct geometric shape.

Rebar for reinforcement is taken of class At-IIIC and At-IVC according toGOST 10884 . All metal parts undergo mandatory anti-corrosion treatment, which significantly increases the service life of the rings. The base of reinforcement, covered with a layer of concrete, must withstand long-term operation in an aggressive environment. Since in most cases the product is installed deep in the ground, the requirements for frost resistance are low and are determined in each specific case by the project (50-75 freeze-thaw cycles are set). For the convenience of lifting the product to a height, mounting loops are introduced into the body.

Well rings KS 15-9 are made of high-strength concrete. They are widely used in the construction of wells and sewer systems. They are made of rebar and reinforcing mesh covered with concrete. The well ring KS 15.9 has dimensions: 1.5 meters inner diameter and 90 cm height. These rings form the base of the well. Depending on the series, manufacturer, the presence of brackets or holes, the rings may have the following marking options:

Well rings are manufactured strictly in accordance with the requirements of GOST 8020-90. They are mainly used for the construction of inspection, drainage, gas and sewer wells, which are necessary both for industrial buildings, large facilities, and for private buildings. Not a single engineering development, not a single architectural project can do without it. With the help of well rings, a shaft is formed, that is, the shaft of the well itself, and the bottom and cover already isolate its space, strengthen it. After all, they are based on high-strength steel wire, which protects against destruction and deformation. The concrete used in the production of KS 15-9 rings must be of good quality, not lower than grade B15.

Rings must be strong, durable, strong and frost-resistant, as well as resistant to aggressive conditions. environment. Softening and blurring of the material is completely excluded by the manufacturer, which guarantees the high quality of reinforced concrete products. All well rings have strict dimensions, the same flat plane and their walls are absolutely homogeneous and are characterized by increased water resistance.

In the production of these rings, they strictly monitor the exact observance of all technological processes. It undergoes constant quality control of products. Strict standards of incoming raw materials are always maintained and ready-made reinforced concrete products are tested for strength. And only after such a tough selection, well rings get to the construction site.

The dimensions are chosen by builders depending on the direct purpose of the well - whether it is a water well, a sewer well, an inspection well or a gas distribution network well. Their diameter can be from seventy centimeters to two meters, and their height is from thirty to ninety centimeters. The material from which the KS 15.9 rings are made is called reinforced concrete, since it contains both reinforcement and concrete. The manufacturing method is not a very complicated technological process: concrete is poured into vibrating cylinders. When turned on, it mixes well and compacts. The mixture itself consists of sand, cement, fine gravel, water and a plasticizer. Round designs of well rings are used mainly for storm channels, economic, household networks.

Drinking wells can also be built from well rings KS 15x9. Concrete does not overgrow with mold and fungus, does not rot, does not oxidize, does not emit toxic substances, is neutral to drinking water and is resistant to other aggressive environmental conditions. Wall rings serve equally well in any climatic conditions, are not afraid of temperature changes and are not deformed by frost. In regulatory documents, well rings are also referred to as KC (centrifuged rings), although their main designation still remains KS - wall rings. They do not lose their shape even if they can be placed under a busy road. The operating time is practically unlimited.

Well rings can also be built “with your own hands”, however, in such a difficult task, it is still better to rely on professionals who strictly follow the entire manufacturing technology, choose the right input material and guarantee the quality, strength and durability of the reinforced concrete product. The technology for manufacturing reinforced concrete rings has been around for about half a century, the development of their production began in the sixties, when they actively began to design and build communication systems not only in large cities, but everywhere where gas was supplied and a drainage system was developed. It is also worth mentioning that wells from such rings are built easier, simpler and faster than brick or stone building counterparts.

Reinforced concrete rings KS 15-9 are used in the construction of wells. In the process of creating shafts for pipelines, sewers, cable networks, various risks arise associated with infiltration of groundwater, collapse or too much pressure of the soil, cracking of the structure under the influence of strong external loads, including vertical ones.

From concrete rings of wells and other reinforced concrete products, a full-fledged mine is created - with a bottom, dense walls, and an upper floor slab. Our company manufactures and supplies such types of products.

Features of marking concrete rings

GOST establishes the rules for marking well rings, which must indicate their type, key characteristics. The marking is XXX-YY-ZZ, where YY indicates the internal section in dm, ZZ is the height, and XXX is the marking of a particular variety. Detailed breakdown in the table below:

Size range

Products made of concrete differ in the following ranges of basic characteristics:

• Height: 1-20 dm.
• Section: 7-20 dm.
• Wall thickness: 0.7-2 dm.
• Weight: 44-1470 kg.

Suitable well rings KS are selected for a specific type of work. Our website contains all the designations and characteristics of products.

Types and purpose of rings of wells KS 15-9

The choice of the size of well rings and their structure depends on their purpose. There are several main types:

• Wall. Are applied to construction of walls of mines under engineering communications. The surfaces and the edge are smooth, no additional lock is provided. Stacked on top of each other using special equipment. When installing, it is important to correctly combine them with each other, seal the seams, check the tightness of their contact.
• With a lock. Their design has a protrusion that allows you to increase the accuracy of docking and significantly improve the level of tightness of communication.
• Auxiliary. They differ in non-standard sizes and are made specifically to order. They are used when you need to get the height during the construction of a well, stormwater or other systems.
• With bottom. They solve the problem of sealing the bottom and eliminate the need to install an additional plate.

From above, the entire structure is covered with an overlap. It compensates for vertical loads and vibrations, the structure has openings for a maintenance hatch.

Production features

Wall reinforced concrete rings of wells are made from heavy concrete brands from M500 and above. Much attention is paid to the recipe - only purified water and well-sifted sand are used in the preparation. Plasticizers are added to increase frost resistance, water resistance.

Increased resistance to stress, cracking is achieved by using steel reinforcement, as well as aggregate - fine gravel. In production, vibrocompaction is used - this makes reinforced concrete products much stronger.

Installation, storage and transportation of well rings KS 15-9

Installation is carried out using special equipment. The design provides for metal brackets - hooks cling to them, and the ring moves to the installation site. If a lock is provided, the level of sealing increases. Workers monitor the correct alignment of the elements, and then coat the seams with mastics based on bitumen and other materials.

It is best to store concrete rings KS 15-9 in a dry room without strong exposure to high temperatures. They are installed on top of each other. Trucks are used for transportation. Unloading is carried out by a manipulator.

Product description

Wall ring of the well KS 15-9 —an element that is used as the basis for the walls of underground wells of various communication networks and sewer septic tanks. concrete rings universal for the construction of the neck and the shaft of the well, which are assembled by welding brackets.

Product marking

Like other reinforced concrete products, wall rings are marked with alphanumeric groups. The first group indicates the type of product, its inner diameter and height.

The second group carries additional information - special design characteristics ("a" - two holes for passing pipelines, "b" - four holes).

For an example of labeling wall ring well, consider KS 10-9a (1160x1000x890 mm), where:

• KS (KC, K)- type of element of the well (wall ring);
• 10 - hole diameter;
• 9 - the height of the ring;
• a- the presence of two holes.

Product types

Rings are classified into ordinary and additional.

• Diameter: 70, 80, 100, 120, 150, 200, 250 cm.
• Height ordinary rings: 30, 60, 90, 100 cm.
• Height of additional rings: 10, 15, 20, 50 cm.

Underground utilities, as a rule, are long, and for their regulated or urgent maintenance, special access points are needed, which are wells. KS 15-9 is one of the constituent elements of this structure. With a length of 90 cm, the outer diameter well ring is 170 cm, internal - 150 cm, which guarantees ease of use of the finished structure. The product is made from heavy reinforced concrete according to state standards. Along with the highest strength, among its advantages are increased water resistance, resistance to temperature extremes and aggressive chemicals.
