Abstract

The utility model relates to building sewage systems and can be used to organize a drainage system in the basement. The technical result of the claimed utility model is: the ability to reduce costs for laying sewer hoods, which can be practically eliminated; provides additional sewage, which can be used as emergency sewer. The claimed technical result is achieved due to the fact that the sewer system of the basement of the building, containing the sewer riser of the building, passing through the basement into the drain sewer piping, containing the sewer of the basement, discharged into the drain sewer, characterized in that the sewer riser of the building connected to the riser of the sewer of the basement with an oblique cross, directed with a slope up to the riser of the sewer of the basement, and n Another place of this connection is the connection of the basement sewer riser with an oblique cross with a downward slope to the basement sewer riser and containing a lever or automatic drain plug.

Description

Application area

The utility model relates to building sewage systems and can be used to organize a drainage system in the basement.

State of the art

According to SNiP 2.04.01-85 * “INTERNAL WATER SUPPLY AND SEWERAGE OF BUILDINGS”, inside the underground or basement of buildings, pipelines may be laid on independent supports and brackets attached to the walls. The fastening of pipelines to supports should allow axial and vertical movement of pipes. For connecting to the riser branch pipelines located under the ceiling of premises, in basements and technical undergrounds, slanting crosses and tees should be provided.

The possibility of joining the sewer of a building in the basement sewage system with building codes is not regulated. Therefore, for the possibility of installing bathrooms in the basement, a separate sewer is practiced.

However, after the removal of a separate sewer drain, a problem arises with sewer air extracts. According to SNiP 2.04.01-85 *, domestic and industrial sewage networks that discharge wastewater to the external sewer network must be ventilated through risers, the exhaust part of which is discharged through the roof or prefabricated ventilation shaft of the building ...

Therefore, to install a sewer hood, it is necessary to make a separate riser to the roof of the building, which is either laid next to the existing riser (which is technically very expensive and requires the consent of all tenants on each floor, which is practically not feasible), or to take out a ventilation riser for the sewer hood outside the house , which is also very expensive and requires the collection of many permits, which is not always possible to obtain due to the fact that not all buildings have the ability to conduct ventilation yazhku outside the house.

The technical result of the claimed utility model is: the ability to reduce costs for laying sewer hoods, which can be practically eliminated; provides additional sewage, which can be used as emergency sewer.

Brief Description of the Drawings

Figure 1 shows a structural diagram of a building that implements a drainage system for the basement, where 1 is the riser of the sewer of the building, 2 is the basement, 3 is the premises of the first and more upper floors of the building, 4 is the drain sewage pipe, 5 - basement sewer riser, 6 - oblique cross with a slope up to the basement sewer riser, 7 - oblique cross with a slope down to the basement sewer riser, 8 - plug, 9 - lever drain or automatic plug, 10 - a boat of the city sewage drainage system, 11 — exhaust vent in the building’s sewage system, 12 — direction of air flow through the sewage system of the building and basement.

The implementation of the invention

The claimed technical result is achieved due to the fact that the sewage system of the basement (2) of the building, containing (see Fig. 1) a riser (1) of the sewage system of the building passing through the basement into a waste sewage pipe (4) of the sewage system, containing the riser (5 ) a basement sewage system discharged into a drain sewage pipe (4), characterized in that the sewer riser (1) of the building is connected to the basement sewer riser (5) with an oblique cross (6) directed upwardly to the sewer riser the basement, and below the place of this connection is the connection of the riser (5) of the sewer of the basement with an oblique cross (7) with a downward slope to the riser of the basement and containing a lever or automatic drain plug (9).

The basement sewer riser may contain a plug (8) at the top to prevent runoff from flowing through the top of the riser when it becomes clogged.

The principle of operation of the basement sewage system is based on the following.

When draining into the riser (5) of the basement sewer, the air (12), carried along with the drain flows, is sucked through an oblique cross (6) leading to the main riser (1) of the building and having an exhaust vent (11) on top of the building building sewage systems. Thus, the exhaust ventilation duct of the common riser (1) of the sewage system of the building is used without the need to make a new one outside the building or through the floors of the building on all floors. Thanks to the junction of the oblique cross (6) of the connection of the riser (5) of the basement sewer with the oblique cross (7) with a downward slope to the sewer of the basement and containing a lever or automatic drain plug (9), it is possible to use the riser (5) basement sewage system as a backup sewage system, which starts when the plug is opened (9). The opening of the plug can be implemented either manually, upon the situation of clogging of the main riser (1) of the sewer of the building, or automatically. The automatic opening of the plug (9) can be realized, for example, on the basis that during the clogging of the riser (1), the drains rise to the level of the oblique cross (6) and block the air flow into the riser (5). If, inside the crosspiece (6), for example, a sensor is installed that responds to direct contact with water, then when it is triggered, the plug (9) opens and the drain flows into the standpipe (5), enter the sewage pipe (4), and from there to the well (10) of the city sewage drain system. Thus, it is possible to reduce the cost of laying a sewer hood, which can be practically eliminated; provides additional sewage, which can be used as emergency sewer.

Claims (2)

1. The sewer system of the basement of the building, containing the riser of the building’s sewer, passing through the basement into the drain sewer, containing the drain of the basement, discharged into the drain of the sewer, characterized in that the riser of the building is connected to the riser of the basement oblique cross, directed with a slope up to the riser of the sewer basement, and below the place of this connection is the connection of the riser tion of the basement oblique crosspiece with a slope down to the sewer standpipe basement containing a lever or automatic drain plug. 2. The sewer system of the basement of a building according to claim 1, characterized in that the riser of the sewer of the basement may contain a plug at the top.
