Wells concrete products: elements and purpose

For access to drinking water, electrical, telephone, gas communications, discharge of waste, groundwater and storm water, it is necessary to build wells. There are many methods of their construction. However, at the moment, zhb wells are the most common.

General information

The best option is to purchase ready-made factory elements for the installation of the building.

It can be:

• well wall rings;
• device necks;
• slab floors;
• trays and bottom structures.

Note! Appointment, which have elements of concrete wells - operation in soils that have any level of aggressiveness. They serve as components of viewing devices for closed-type pipelines, filtration wells, gravity collector analogues. They can transport both production and household fluids in all climatic zones of the Russian Federation, in addition to the permafrost regions.

1. Depending on their purpose, elements of reinforced concrete wells may have different weight, diameter, and height.

1. The main finished part of communication networks is rings. Currently, manufacturers produce three of their most common varieties, distinguished by diameter. They are marked as COP / 10, COP / 15 or COP / 20. Their cross-section, respectively: 1000, 1500 and 2000 millimeters. The height of these elements of the wells is the same and is 900 millimeters.
2. Additionally, concrete plants produce "additional" rings, the most common of them are KS / 7/5, having a diameter of 0.7 meters and a height of 0.5 meters.
3. As it becomes clear, the standard dimensions of reinforced concrete rings for the well are as follows: diameter - 0.7 / 2 meters, height - 0.1 / 0.9 meters. Based on the dimensions, products can weigh from 43 kilograms to 1470.
4. At arrangement of reinforced concrete wells it is necessary to use slabs for floors and bottoms, which are selected based on the diameter of the structure. Such products for the bottom are designated as PD or PN, analogs for floors - PC or PP.
5. Zhb products for wells should be made using a concrete mixture of grades m-200/500. They must fully comply with the requirements that are voiced in GOST 8080/90.

Ready elements of wells

A little bit about how concrete elements are made of reinforced concrete wells.

In fact, the technology of these products is very simple.

1. At first, the form for the well element is placed on a special metal tray or on a flat floor surface.
2. Further in it the reinforcing framework keeps within.
3. Then a concrete mix is ​​poured into the mold.
4. After that, by means of vibration, the workpiece is compacted. Due to this, concrete is compacted and gains additional strength.
5. As required, during this process, new portions of the solution are added to the form.
6. After the product dries enough, it is transported to the place of storage, where it is removed from the form. Then the whole process is repeated.
7. The instruction prescribes the production of all elements for ready-made concrete structures using special working drawings. For example, this may be the document “Concrete products for wells of sewage and water pipes that have a round shape” (series No. 3.900.1 / 14).

Product Benefits

Reinforced concrete products are so widely used, thanks to the following technical characteristics and performance.

1. They are durable, due to the use of concrete mixture reinforced with a metal frame.
2. Parts of wells have a high level of strength and resistance to compression loads.
3. ZHBI the well has almost full water tightness.
4. The construction is mounted quickly and does not require special skills for this.
5. Such devices are simply maintained and repaired, as cleaning their smooth and even surfaces or completely replacing an element is easier than performing such actions with brick, stone, or wooden counterparts of wells.
6. The relatively low price of products makes them attractive both for businesses and for private developers.
7. The material of these elements has an ecological purity.
8. The products are multifunctional and versatile. It is widely used not only for arranging wells with different purposes and sizes, but also for communications of thermal, electrical, telephone networks.

Purpose of finished reinforced concrete elements

Ready-made factory reinforced concrete elements are often used during installation:

• water wells;
• viewing analogs for the household and drainage sewerage;
• filtration devices;
• drainage facilities;
• cleaning sewer devices of accumulative type - cesspools and septic tanks;
• fixed formwork for the construction of foundations for various objects.

Marking rings

The rings that make up the zhb well are marked with lettered and digital groups.

The letter indicates the type of product.

1. Bearing rings - KO.
2. Analogs intended for the arrangement of working well chambers in gas and water systems - KVG.
3. Wall elements used in working chambers, as well as narrow well necks - KS.
4. Rings that perform the functions of mines in sewer and drainage networks - KFK.
5. Analogs produced for the arrangement of well chambers in storm and drainage systems - CLA.

Next come two digits. The first of them indicates the cross-section of the product, in decimeters, and the second - its height.

Conclusion

If you are planning to put a concrete well on the site for any engineering network with your own hands, then you must accurately select the type, diameter and height of its elements.

To do this, carefully plan all the work. Check out the video in this article. It will provide you with additional information on the topic.
