某十五层民用住宅楼的建筑给排水毕业设计_————— —.doc

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,一到六层为低区,由市政管网直接供水。七层到十五层为高区,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 15 layers buildings of the public residence building to , completing the design of the water supply system and draining the system, fire fight system, the hot water system and the system of the roof rain water.
The water supply system adoption cent area supply water. 1-6 low areas of the layers is taken care of the direct water supply by the municipal . The seventh layer to the 15th layer is high area, adoption north bound descend to of water supply method, pump to supply water to a water tank of the roof from the water supply of the underground garage, then be taken care of water supply toward high area by a water tank; Drain the system adoption is a dirty water, the waste water confluence system, the first floor drains alone, draining to sign the tube to establish to stretch the crest to ventilate the tube only, the dirty water was handle by septic tank again rear row to municipal soil ; The fire fight system design es to eliminate the fire to bolt to extinguish fire the system, a fire water of the early 10 mins is supply by the fire fight water tank, normal the water supply be pumped by the fire fight Pump from the Saving pond ;The hot water system divides the area circumstance in accordance with the cold system of water, the cold water passes to give or get an electric shock after the heating apparatus concentration heat, again from promote the pump to provide to go together with the pipe , The hot water adopt is the closing type machine half circulatory system; The
