Abstract:This design of the building for 17 layer comprehensive civil building, water supply and drainage engineering design including the indoor living water supply system design, indoor drainage system design, indoor fire water supply system is designed, and the hot water system design. The drinking water system is divided into two parts: one to three layers for the low area, use of municipal water supply pipe network water directly; 4 to 17 layer is high area, using the high roof water tank to supply water system. Fire water system is divided into fire hydrant water supply system and automatic sprinkler fire extinguishing system, this building is a kind of civil construction, and the building height 50 m or more, according to provisions of the code for fire protection design of tall buildings, indoor and outdoor fire hydrant water hydrant water respectively take 20 l/s and 15 l/s, automatic water spray system calculation for the 16 l/s, automatic sprinkler system in the roof pressurization device. Rain drainage system USES corrupt confluence system, drainage system USES special ChanLi stretch top ventilation pipe drainage system, ventilation roof above 1.60 m. Water supply system adopts gangsu composite feed water pipe, fire hydrant water supply system and automatic sprinkler fire extinguishing system with seamless galvanized steel pipes, drainage riser using PPI spiral pipes, drainage branch pipe of each layer USES the ordinary UPVC drainage pipe.
