摘 要

给水系统分区供水，从市政管网上接一根DN100的引入管，地上三层为市政管网直供，四至九层采用变频供水设备加压供水。消防水池采用钢筋混凝土结构，置于地下室泵房外侧，有效容积334立方。建筑室内排水采用污、废水分流制，室外排水采用污废合流制，排入检查井后，经化粪池处理再排入市政污水管。卫生间采用多设立管形式，采用专用通气立管，部分增设环形通气管。地下室排水经排水沟汇集排至集水坑，经潜污泵提升排至检查井。建筑立面为全玻幕墙，采用内排水，选择重力半有压流系统，雨水经屋面雨水斗收集后由雨水管排至检查井。

根据规范，该建筑为二类高层建筑，室外消火栓用水量20L/s，室内消火栓用水量20L/s，火灾延续时间2h。消火栓充实水柱高度12m，水龙带长度20m，水枪喷嘴流量5.16L/s，消防立管管径为DN100。在屋顶层设试验消火栓一个，每个室内消火栓箱内均设有远距离启动消防泵的按钮。

该建筑采用湿式自动喷水灭火系统，喷淋系统设计流量20L/s。报警阀设于地下室泵房内，各层均设水流指示器、末端试水装置和信号阀，其信号均送入消防控制中心进行处理。本工程的自动喷水灭火系统分2个区。选用箱泵一体化消防增压稳压设备（包含18立方米消防水箱）贮存火灾初期10min自动喷水灭火系统、室内消火栓系统用水量，初期灭火由水箱供水，后期灭火由地下室的消防水泵和喷淋泵供水。

Abstract

Water supply system water, from municipal pipe network pick a service pipe DN100, four floors for the direct supply of municipal pipe network, four to nine layers with variable-frequency water supply equipment pressurized water . Fire pool used for reinforced concrete structures placed in basement pumping station outside the effective volume 550 cubic. Construction indoor drainage-diversion of sewage, waste water, an outdoor drainage sewage waste combined, after discharged into the manhole, septic tank treatment and then discharged into municipal sewers. Toilet multi-established forms, special ventilation risers, some additional loop vent. Basement drainage flow sewer collection to sump, submersible sewage pump lifting flows into the inspection Chamber. For the whole glass curtain wall building facades, internal drainage, select half-pressure of gravity flow systems, rainwater flow roof rainwater collected by the rain water pipe to manhole.
According to the specifications, the building two high-rise construction, outdoor fire hydrant water 30L/s, 30L/s fire hydrant water consumption, fire life 2h. 12m fire hydrant full water column height, hose length 25m, 5.16L/s water gun nozzle flow, fire the riser tube diameter DN100. Set up a test fire hydrants in roofing, each fire hydrant boxes are equipped with remote start button for fire pump.
Wet automatic fire sprinkler system in the building, spraying system design flow 20L/s. The alarm valve located on the pump room in the basement, the floors are located water flow indicator, test water device and signal the valve at the end, its signal is fed into the fire control centre for processing. Sprinkler system the project divided into 3 zones. Selection box-pump fire booster regulator device integration (including 18 cubic metres of fire water tank) storage initial 10min sprinkler system for fire water, indoor fire hydrant system, initial fire-fighting water tank water supply, late extinguishing the fire pump and sprinkler pumps water from the basement
