- I - 摘要
该工程是位于重庆市的一栋八层的住宅楼。本设计是对这栋住宅楼的给水排水系统进行设计,设计范围主要包括建筑物的生活给水系统、消防给水系统、污废水排放等系统。其中,生活给水设计包括建筑的分区、给水方式的选择、水泵计算和选择。该设计给水方式采用分区供水方式,一至四层为低区,由市政给水管网直接供水;五至八层为高区,由高位水箱进行供水。消防给水包括消火栓的布置与计算,消防水泵计算和选型。消防水箱贮存10min的消防水量,火灾发生初期由水箱供水灭火,正常供水由消防水泵从地下贮水池内抽取。排水系统包括排水管道的计算和排水管道的布置。采用污水和废水分流排放的排水系统。给水管道采用PP—R管,排水管道采用UPVC管,消防给水管材采用镀锌钢管。

The project is a 8-storey residential building in Chongqing. This is a
design of water supply and drainage systeme to the residential building. The
design mainly contains living water supply system、fire water supply system、drainingsystem.Thedesign of living water supply includes the building
partiton、the choosing of water supply’s method、the calculation and choice
of pumps. The design of living water supply adoptthe method of cent area
supply water, the 1~4rd floor is the low district, the source is the municipal
water-supply net-work. The hight district is the 5~8rd floor, the source is the
tank of the roof. The design of fire water supply includes the settings of
hydrants 、the calculation and choice of pumps. Fire fight water tank storage
water for 10 minutes fire water, normolwater supply be pumped by the fire
fight Pump form the Saving pond. The design of sewerage system includes
the calculation and arrange of drain pipes, use the sewage and waste water
separate drainage system. The water pipe adoptPP—R tubes, the drain pipe
adopt UPVC tubes, the fire fight system adopt zinc steel pipe.
