Abstract:The design of building water supply and drainage of Copper Mt. Xinyuan building design, design is the main building water supply, drainage, water, fire control system.

　　　The design of the building is located in Xuzhou District of Copper Mt. City, is a comprehensive civil building 12 tall. Including indoor living water supply system design, indoor drainage system design, indoor fire water supply system design, and the design of rainwater system design of water supply and drainage engineering. Life water supply system is divided into two zones, one to two layers as low area, the municipal water supply pipe network to supply water directly, the three layer to the twelve layer for high, use of roof water tank for water supply system. Fire water supply system is divided into fire hydrant system and automatic sprinkler system, the construction of a class of civil building, and the building height greater than 50m, according to the "Regulations" code for design of fire system of high rise civil buildings, indoor fire hydrant water and outdoor fire hydrant water respectively from the 20L/s and 15L/s of the automatic sprinkler system, calculation of water for 16L/s, automatic sprinkler system with pressurized equipment on the roof. Drainage system using sewage waste sewage system, drainage system with special ventilating single stack drainage system, ventilation at high roof 1.00m. Water supply system adopts PP-R water supply pipe, fire hydrant system and automatic sprinkler system adopts the seamless galvanized steel pipe, drainage riser with PPI spiral drainage pipe, the drainage pipes using ordinary UPVC drainage pipe. In the underground layer is provided with a storage tank and the pressure pump, the basement a sump, sump is arranged in the submersible sewage pump sewage discharged timely, ensure.
