2.2 Input device and design.

The entry is routed at right angles to the exterior wall of the building with the smallest length. Number of entries to the building: 1. The diameter of the input is 100 mm. The inlet is connected to the external water supply network by a saddle.

Depth of laying taking into account ground freezing:

H _ hall = H _ prom + 0.5 (to the bottom of the pipe) = 2 + 0.5 = 2, 5m,

Input slope: 0.005 towards the outside network for emptying; input length is 18 m.

2.3 Water metering unit.

The water metering unit consists of devices for measuring the amount of consumed water, shutoff valves, control and discharge crane, connecting shaped parts and branch pipes. Shut-off valves are installed before and after the measuring device for replacing or checking the readings, as well as for disconnecting the internal water supply system and its emptying. The control and discharge valve (or branch pipe with plug) is used to lower water from the internal water supply network, monitor pressure, check the correct reading of the measuring device and detect water leakage in the system. The water metering unit is located in the basement. Impeller counter d = 25 mm is used as measuring device. Meter is located on horizontal section of pipeline

2.4 Structure and design of the internal water supply network.

Main pipelines are attached under ceiling at a distance of 0.5 m to construction structures on brackets. Risers, outlet pipelines and pipelines to water-disassembly devices are laid with open gasket. Horizontal pipelines are laid with a slope of 0.005 towards the inlet for possibility of water descent from the system. Water supply risers are located in the box behind the toilet. The pipelines from the risers to the water discharge valves are laid along the walls 0.1 m above the floor.

Shut-off valves are installed at the base of the risers, at the entrance to the apartments, in front of float valves of flush tanks, in the water metering unit, on the entrances to the irrigation cranes.

Steel non-galvanized pipes with a diameter of 20.25.32 mm are used for internal water supply. For their connection, straight or transition connecting parts (fittings) made of ductile iron and steel are used. Couplings and burners are used for the releasable connection device.

Sewerage.

3.1 Internal sewage network design and arrangement.

By the nature of sewage pollution, the sewage system is domestic. The sewerage system consists of the following elements: sewage receivers, a network of pipelines (branch lines, risers, headers, outlets). The internal sewerage system is equipped with the following devices: for ventilation (ventilation pipelines), for cleaning in case of clogging (inspections, cleaning) and for protecting the premises from ingress from the sewage network of gases (hydraulic gates - siphons). Waste water is drained by gravity into the intraquartal sewage network.

To ensure reliable and uninterrupted operation of the internal sewerage network, it provides for audits and cleaning. At least three floors are installed on the revision risers, namely on the first, third and fifth floors. Cleaners are installed at the turns of the network, at the beginning of the sections, on horizontal sections, at the exit of the outlet from the building and after the last riser is connected to the outlet.

For ventilation of networks, exhaust pipes, which are a continuation of sewage risers. They are brought through the roof to a height of 0.3 m. The diameter of the exhaust pipe is equal to the diameter of the sewer riser 100 mm.

Discharges of waste water from the risers outside the building into the intra-quarter network are laid with provision of smooth connections to the risers. To lay the exhaust pipe in the foundation wall, an opening is left providing a gap around the pipe of 0.3 m.

From baths, washes and washbasins, branch pipes are laid with a diameter of 50 mm with a slope of 0.035 to the riser to ensure gravity flow of waste water. From the toilet, a 100 mm diameter branch pipe with a slope of 0.02. Branch pipelines are connected to the riser by means of oblique crosses and tees .

The exhaust slope should be assumed to be 0.02 at Ø 100 mm. Inspection wells are designed at the points where the outlets are connected to the yard network. Depth of extension H _ (hall) = H _ prom0.3 = 20.3 = 1.7 m.

For the network device cast-iron sewage funnel pipes and shaped parts are used to connect them into units and systems with a conditional passage of 100 mm. Sealing of annular clearances in joints of funnel sewage pipes is made by resin strand. Sewage receivers are sanitary devices, ladders, drains, funnels, trays. Gutters are installed on the roof surface to receive rainwater.

3.2 Arrangement and calculation of the yard sewerage network.

Round wells, which are installed on pipelines with diameter up to 500 mm inclusive, have internal diameter of working chamber 1000 mm. Monitoring of the network operation during operation, inspection of the network, and, if necessary, cleaning and washing of the network are carried out through inspection wells.

According to the plot plan for the transportation of waste water from the building to the external sewer network, we will design a yard sewer, since there is a red line - the sewer boundary. Yard sewage is designed from cast-iron funnel sewage pipes ≥ 150 mm.

The yard sewer intersects in plan with the city water main at a distance of 1.1 m ≤1,5 m [84.8-83.7 = 1.1 m] in light, so the water supply at the intersection consists of a metal casing.

Pipes of different diameters in the wells of the palace network are connected by the "silk-to-silk" method.
