Description

Scope of the invention: “Construction; mining engineering".

The invention relates to the construction of sewerage systems for apartment buildings.

Currently, sewer systems of apartment buildings are designed and built on the basis of SNiP 2.04.01-85. According to SNiP requirements, wastewater should be provided through closed gravity pipelines with equipment in convenient locations for the operation of revisions and cleaners. In the construction of sewer systems in apartment buildings, polyethylene sewer pipes and fittings made to them are used according to GOST 22689.2-89.

BACKGROUND OF THE INVENTION: In apartment buildings, as a rule, the sewer risers of apartments are brought to the zero level of the basement and then with a slope of 0.035 are connected to the outlet to the city sewer, and no protective devices are provided for flooding the basement. The disadvantage of this design is that when the sewage level rises in the sewer wells of the city sewage system, because of the occurrence of blockages, frequent flooding of the basements of apartment buildings occurs. The result is an unsanitary condition in the basement, unpleasant odors in the hallways of the house. Also, due to frequent flooding of basements with sewage from the sewer system, the foundation of the house and other supporting structures suffer, which can lead to a reduction in the life of the apartment building.

The aim of the present invention is to prevent and prevent flooding of the basement of an apartment building with sewage from a city sewer.

Disclosure of the invention: The invention allows to prevent and prevent flooding of the basement of an apartment building with sewage from the city sewer network in cases of rising levels of sewage in wells due to clogging. To do this, it is necessary to rebuild the sewer system of an apartment building. Reconstruction of the sewerage system consists in changing the sewerage units in the basement of each entrance, which have a separate independent connection to the citywide sewerage system. When rebuilding the sewage system, polyethylene sewer pipes and fittings for them are used in accordance with GOST 22689.2-89.

The technical solution proposed by this invention consists of the following components (Fig. 1);

(1) the outlet point of sewage water K1-1;

(2) sewer coupling, type KK, NPVH110;

(3) sewer audit, NPVH110, gray;

(4) check valve, membrane NPVC 110, gray or orange;

(5) drainage sewer NPVH110, type KkK-45 °;

(6) steel bend, 100 mm;

(7) steel shut-off valve DU110;

(8) sewer tee NPVH 110, gray;

(9) a waste water collection tank;

(10) fasteners for sewer pipes to the ceiling and basement walls;

(11) wire fasteners for the alarm system loop;

(12) Astra 361 or Aquarius-R sewage presence sensor;

(13) alarm loop wire;

(14) GSM module "Astra 882";

(15) reception and control device of the alarm system (PKP) "Astra 712";

(16) GSM antenna;

(17) risers of the sewage system of apartments.

In contrast to the existing sewage systems of multi-family residential buildings, the technical solution proposed by this invention consists in the fact that an assembly is established at a convenient working distance from the outlet point (1) by connecting the elements in series in the following order: revision (3), check valve (4 ), revision (3). Further, through branch (5), the sewer pipe at an angle of 45 ° rises from the basement floor to such a height that the distance from the ceiling to the sewer pipe is 500-600 mm, while the sewer pipes are attached to the ceiling and basement walls using clamps and pins . This assembly with the help of sections of sewer pipes and bends is connected to the risers of the apartments of a residential building, while all sections use polyethylene sewer pipes and fittings to them in accordance with GOST 22689.2-89. The sewage system through the second socket of the drain (5) with the help of steel branches (6) and through the steel shut-off valve (7) is connected to the waste water collection tank (9).

When the non-return valve (4) is activated, which closes the sewage system when the sewage level in the city sewer wells rises due to clogging, the problem arises of draining sewage from the apartments of the house, as the excess pressure created by the city sewage system counteracts the drain. There is a risk of spillage of sewage in the apartments of the first floor through the toilet due to the filling of sewer pipes in the basement of the house. To eliminate the problem in the basement, a container (9) for collecting wastewater is installed. In the case when there are 40 apartments in one entrance, the sufficient tank capacity is 4 m ³ , which allows the accumulation of wastewater for at least 4 hours in the daytime and 8 hours in the night.

To implement a technical solution for collecting wastewater into a tank, it is necessary to raise sewage pipes in the basement to a height of at least 200-300 mm from the top edge of the tank. It is also necessary to equip on the sewer pipe a device consisting of a tee (8) and outlets, which ensures the discharge of wastewater into the tank when the check valve is activated and prevents the sewage from entering the tank during normal operation of the sewer system. To solve the issue of preventing flooding of the basement at home, the system must be equipped with an alarm system, since the inspection of basements by plumbing services is not carried out systematically. At a height of 150-300 mm, from the bottom of the tank, a water presence sensor (12) is installed. The alarm system consists of industrial designs of devices used in the preparation of fire alarm systems. Install and maintain the alarm system of organizations that have licenses for the installation and maintenance of fire alarm systems in buildings and structures. The signal through the Astra 712 alarm system control panel (PKP) (15), the Astra 882 GSM module (14), the GSM antenna (16) through the channels of the cellular communication system is received by the dispatcher of the management company in the form of a message containing the text object address and entrance number. The dispatcher sends a plumber team to the specified address, and also transmits information to the city Vodokanal.

The system works in the same way in cases of clogged sewage in the area from the border of the building to the well of the city sewer. In these cases, sewage sewage from the apartments begins to accumulate in the tank. The sensor gives a signal for the presence of water, the message goes to the dispatcher of the management company, plumbers are sent to the place.

After the liquidation of the accident, the shut-off valve (7) of the storage tank opens, and waste water is poured into the city sewer; it takes 2-5 minutes of time based on the amount of accumulated fluid. The container is washed with water and disinfected with a solution containing chlorine.

This invention is implemented in an apartment building. For two years of operating the system, the basement of the house has never been flooded with sewage. Before the reconstruction of the sewage system, the presence of sewage in the basement of the house was a frequent occurrence.

Description of the drawing.

The drawing is executed in a scale of 1:50.

An assembly consisting of three elements in the sequence is installed at a convenient distance from the outlet point K1-1 (1) for operation, revision (3) - check valve (4) - revision (3). Next, a tee (5) is installed with a tap of 45 °. In the main line, the sewage pipe through the steel bends (6) and the shut-off valve (7) is connected to the tank (9). On the branch, the sewer pipe rises to a height of 1600 mm and at a distance of 600 mm from the basement ceiling, is rigidly attached with a clamp and pin to the ceiling of the basement and to the walls. A drain is installed in the tank from the tee and bends. Observing the necessary slopes, the sewer pipe at the level of 1600-1650 mm from the basement floor is connected to the sewer risers of the apartments (17). When rebuilding the sewage system, polyethylene sewer pipes and fittings for them are used in accordance with GOST 22689.2-89.

The alarm system consists of a control panel (hereinafter PKP) (15). In this case, the Astra712 control panel, the Astra 882 GSM module (14), the GSM antenna (16), the Astra 361 or Aquarius-R water presence sensors (12).
