Description

The field of technology.

The claimed technical solution relates to sewage systems and is used for the construction of storm drainage wells, as well as sewer wells for septic tanks with wastewater treatment.

The level of technology.

It is known, for example, a reinforced concrete wall ring for viewing wells of water supply and sewage (RF patent for utility model No. 10192, IPC E03F5 / 00, 1999, [1]). As in the claimed technical solution, the specified analogue [1] is a hollow vertical wall element.

Reinforced concrete wall ring [1] has a cylindrical shape. The wall of the ring is solid. On the upper and lower bases of the ring, grooves are made, which in cross section have the shape of a rectangular trapezoid with the formation of protrusions. When installing the inspection well, the protrusions of adjacent rings enter the corresponding grooves, precisely fixing the rings relative to each other.

The closest analogue of the claimed technical solution is a concrete wall ring (Internet resource http://www.zavod-pbk.ru/products/120089179-koltsa_betonnyye_zhbi_x_15_9_perforirovannyye_dlya_septika, 02.20.2018, 20:43, [2]). As in the claimed technical solution, the wall of the specified analogue contains through holes that allow the liquid fraction to seep into the ground.

The holes of the prototype [2] have a round shape.

A technical problem, the solution of which is ensured by the implementation of the proposed technical solution, is the need to prevent clogging of through holes in the wall of the ring.

The solid wall of the analogue [1] does not allow drainage of wastewater. This narrows the scope of the wall ring.

The prototype [2] there is a clogging of holes with both external soil and the internal solid fraction of sewage.

Disclosure of the essence of the technical solution.

The first technical result provided by the claimed technical solution is to prevent clogging of the through holes of the wall ring.

Other technical results are an increase in the contact spot with the soil surface and the filter system, preventing the ingress of crushed stone, into the septic tank drainage chamber.

The essence of the claimed technical solution lies in the fact that the wall ring contains through holes. It is characterized in that the dimensions of each through hole on the inner surface of the wall are smaller than the dimensions of the hole on the outer surface of the wall. In this case, the through holes in the longitudinal section are trapezoidal, and in the cross section they are rectangular.

The above essence is a combination of essential features of the claimed technical solution.

In special cases, it is permissible to perform a wall ring as follows.

The wall ring preferably has a cylindrical shape.

The wall ring is mainly made of concrete.

The wall ring may be provided with gripping holes or sling loops.

The authors of the technical solution made a prototype wall ring, the tests of which confirmed the achievement of technical results.

A brief description of the drawings.

The figure shows a wall ring.

Implementation of a technical solution.

The wall ring (1) (Fig.) Predominantly has a cylindrical shape and contains through holes (2), which serve to divert the liquid cleaned wastewater fraction from the well.

The dimensions of the through hole (2) on the inner wall surface are smaller than the sizes of the hole (2) on the outer wall surface. In the longitudinal section, the holes (2) have a trapezoidal shape, in the transverse rectangular. The aforementioned shape of the holes (2) does not allow them to become clogged with both external soil and solid wastewater fractions.

The wall ring (1) is made of heavy concrete of class B20 - B25. As the reinforcement, steel of classes Vr-1, A-1, A-II, A-III is used.

For slinging during transportation and installation, the rings (1) are provided with gripping holes or sling loops made of A-1 steel (not shown).

Examples of specific performance.

Example 1. The preferred dimensions of the through holes (2) are shown in table 1.

The implementation of the proposed technical solution is not limited to the above examples.

The order of use.

The wall ring is used for the construction of drain pits and septic tanks, filtration or drainage wells. The holes (2) in the walls of the perforated ring allow the liquid fraction to seep into the ground. After filtration, treated effluents are absorbed into the soil. The shape of the holes (2) prevents them from clogging with both external soil and the internal solid fraction of sewage. At the same time, an increased contact spot with the soil surface contributes to the drainage of wastewater.

Industrial applicability.

The claimed technical solution is implemented using industrially produced devices and materials, can be manufactured at any enterprise producing building materials and will be widely used in sewage systems.

Claims (4)

1. Wall ring containing through holes, characterized in that the dimensions of each through hole on the inner surface of the wall are smaller than the dimensions of the hole on the outer surface of the wall, while the through holes in the longitudinal section are trapezoidal and rectangular in cross section. 2. The ring according to claim 1, characterized in that it has a cylindrical shape. 3. The ring according to claim 1, characterized in that it is made of concrete. 4.
