摘要:本设计是某十五层民用住宅楼的建筑给排水设计，主要包括给水系统、排水系统消防系统、热水系统和屋面雨水系统五个部分。
给水系统采用分区供水，一到四层为低区，由市政管网直接供水。五层到十五层为高区，采用上行下给的供水方式，由地下车库的供水泵供水到屋顶的高位水箱，再由高位水箱向高区管网供水；排水系统采用的是污、废合流制，底层单独排水，排水立管仅设伸顶通气管，污水再经化粪池处理后排向市政污水管网；消防系统设计成消火栓灭火系统，火灾初期10min的水由消防水箱供给，正常供水由消防水泵从贮水池内抽取。热水采用的是封闭式机械半循环系统，分区情况和冷水系统一致，冷水通过电加热器集中加热后，再由提升泵供向配水管网；雨水采用的是内排水系统，雨水直接排向市政污水管网。给水管和排水管分别采用PP—R管和UPVC管，消防系统和热水系统都采用镀锌钢管。
设计过程进行了各系统方案的确定、平面布置和计算,以及各种设备的选型,并做工程概算和Excel宏编制程序。最后用CAD绘制了各个系统的平面施工图和系统轴侧图。

Abstract:This design is a fifteen storey residential building to the drainage design, including water supply system, drainage system, fire system, hot water system and roof rainwater system five parts.
Water-supply system partition, one to six layers as low area, by the municipal water supply pipe network directly. Seven to fifteen layers as high area, the upstream to water supply mode, by the high water tank underground garage water pump water supply to the roof, and then by the high water tank to the high network; sewage drainage system is used, waste sewage system, the separate drainage, drainage tube only reached number of trachea, wastewater treated in the septic tank back into the municipal sewage pipe network; fire system design into a fire hydrant system, the early fire 10min water from fire water supply, the normal water supply of fire pumps from the tank extraction. Hot water is used in closed mechanical circulatory system, partition and chilled water system, cooling water through the electric heater heating, again by the lift pump for the water distribution network; rainwater is used within the drainage system, rain water is directly discharged into the municipal sewage pipe network. Water supply and drainage pipes were used PP - R pipe and UPVC pipe, fire and water systems are made of galvanized steel pipes.
The design process of the identification system, layout and calculation, selection and various types of equipment, and do the project budget and the Excel macro program. Finally, CAD drawing of the construction plan and the system of various systems of Axonometric drawing.
Keywords High-rise building; building drainage; water supply pipe
