Description

The utility model relates to relates to utilities, in particular to the wells of external engineering networks, and can be used in the construction of wells and chambers of external engineering networks of water supply, sewage, heating and other networks.

Well-known designs of wells of engineering networks of wall rings and bottom plates for according to the series 3.900.1-14, GOST 8020-90, containing the bottom plate and wall rings. According to the standard series TPR 901-09-11.84; TPR 902-09-22.84; series 3.900.1-14, GOST 8020-90, when installing a well on a bottom plate, a wall ring is mounted on the cement mortar, then the next wall rings are mounted on it, then the floor slab and the neck of the well on it. In water-saturated soils, the weakest point is the joint between the bottom and the first wall ring. In conditions of constant water backwater it is very difficult to make a high-quality tight joint between the bottom and the wall ring.

The closest technical solution is a plastic well with a design of the lower part of a prefabricated or welded plastic well (http: // Zhilkomsnab.rf / products / sewer systems / wells - plastic /, http://www.polimerco.ru/kolodcy). The welded plastic well is leakproof and does not allow groundwater to pass through. But since it is light in weight, its lower part must be loaded, otherwise it will surface. As a rule, the lower part is loaded with reinforced concrete. The disadvantage is the fragility of the material, so a protective reinforced concrete slab should be mounted on the roadway above the well (SP 40-102-2000, clause 6.8.2.). In addition, the cost of a plastic well is higher than a reinforced concrete well.

To eliminate these drawbacks, a technical solution is proposed in which the design of the well for external engineering networks contains a bottom ring made in a single unit. This ensures tightness from groundwater, increases strength, simplifies installation and operation of the well. The proposed technical solution: combine the bottom with the first wall ring in the manufacture, to exclude the mounting joint between the bottom and the wall ring and thereby prevent the penetration of water through the lower joint.

This proposal will allow us to abandon the machine, which we have to constantly keep for pumping water out of the well, to reduce the time of emergency recovery work, since you can quickly close the valve and begin repair work. At the same time, the fittings inside the wells are less susceptible to corrosion, and the volume of pumped water in sewer systems is reduced.

The well with the lower part in the form of a ring-bottom can be used in the construction of round wells for household, storm sewers, water supply networks. Wells can be installed in the green area and on the roadway. Rings-bottoms can be made with holes for pipes for specific sizes.

Advantages achieved as a result of the proposed technical solution:

- ensuring the tightness of the lower part of the well from the penetration of groundwater in the base reinforced concrete well;

- no additional devices and parts are required to prevent the ascent of the well;

- the possibility of widespread use of this technical solution when introducing manufacturing at any reinforced concrete plant;

- the cost of a well with a bottom ring is significantly lower than a plastic one.

The technical result is an improvement in the operational characteristics of the well, in particular, increasing strength, stability, simplifying installation, preventing the ascent of the well.

The technical result is achieved by the construction of a well containing a wall ring and a bottom made of reinforced concrete, characterized in that the lower wall ring is made integrally molded as a unit with the bottom, while the diameter of the bottom D is larger than the outer diameter of the cylindrical surface of the ring of the well, and the geometric center of the bottom and the center of diameter the rings are on the same axis, which increases the stability of the well.

The essence of the technical solution is illustrated by the figure, which shows the ring-bottom in the context, where

d is the inner diameter of the wall ring

D - maximum horizontal bottom size

h - bottom plate thickness

H is the height of the bottom of the well.

An example implementation.

The bottom ring is made in a metal mold consisting of a metal pallet on which two sliding metal sides are fixed. To form an internal cavity in the form of a cylinder, a removable metal core of diameter d is installed on the sides, which determines the internal diameter of the cylindrical surface of the wall ring, which, after compaction of the concrete mixture and a short exposure, is taken out of the concrete body. Before pouring the concrete mixture into the metal mold, reinforcement is installed. The product in metalloform is placed in a steaming chamber. After the heat treatment cycle, the metal mold is removed from the chamber and, when the product cools down, it is removed from the metal mold.

Thus, the bottom ring is a one-piece reinforced concrete product, provides well stability, high strength when used on the carriageway, prevents the well from floating, and the tightness of the internal cavity from internal waters.
