Abstract:The design of the building is sixteen story commercial building. Including the design of indoor water supply system design of indoor water supply and drainage system and drainage engineering design, the design of indoor fire water supply system, and the design of rainwater system. Life water supply system is divided into two zones. One to four layers as low area, the municipal water supply pipe network to supply water directly. Five to sixteen layers for high, use of roof water tank for water supply system. The total height of the building is 47.5 m, for commercial building, belonging to the dangerous level I, according to the code for fire protection design of tall buildings, building height greater than 24m or volume ≥ 5000m ³, fire hydrant water gun full water column spacing should be guaranteed the same layer any part of 2 fire hydrant at the same time. According to the specification, the building belongs to the two type of building, building height <50m, outdoor fire hydrant water 20L/s. According to the design specification of the building of water density is 6L/min.m2. . drainage system using sewage waste sewage system, drainage system with special ventilating single stack drainage system. Water supply pipeline with concealed laying, pipes are UPVC pipe, using the socket interface, with elastic sealing ring connection. drainage riser with PPI spiral plastic drainage pipe. Each layer of the drainage pipes using ordinary UPVC drainage pipe. According to the design data, the construction of high-rise building, 1~2 floor is for shops, 3~16 layer for ordinary residential, this design only consider the residential hot water supply, the other does not consider the supply of hot water. Dry pipe, vertical pipe are made of composite plastic pipe. Check the specification, the maximum daily water consumption quota is 80L/.D, the use of time for 24h.
