摘 要

给水系统分区供水，从市政管网上接一根DN200的引入管，1#1楼一至五层由市政供水，六至十三层为中区，十四至十八层为高区，中区和高区均采用变频泵供水方式。1#2楼一至五层由市政供水，六至十四层为中区，十五至二四层为高区，中区和高区均采用变频泵供水方式。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670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。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。雨水采用重力半有压流系统，雨水经屋面雨水斗收集后由雨水管排至检查井。

根据规范，该建筑为一类高层建筑，室外消火栓用水量30L/s，室内消火栓用水量40L/s，火灾延续时间2h。消火栓充实水柱高度12m，水龙带长度25m，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40L/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。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 partition from the municipal pipe network access a DN200 introducing tube, 1 # 1 floor one to five from the municipal water supply, was in the region of six to thirteen, fourteen to ten eight-story high-district, Central and High areas are using frequency pump water supply. 1 # 2 floor one to five from the municipal water supply, four for the area six to ten, fifteen to twenty four for the high zone, middle zone and high district adopts Frequency Conversion Pump. Fire basin made of reinforced concrete structure, located on the outside basement pumping stations, the effective volume of 670 cubic meters. Architecture Indoor use sewage drainage, waste water diversion system, outdoor drainage system using waste and sewage confluence, after checking into the well, the septic tank and then discharged into the municipal sewer. Toilet multi-establishment tube form, using special ventilation riser. Basement drainage ditches pooled by row to the sump, the submersible sewage pump discharge to upgrade manholes. Rainwater half pressurized by gravity flow systems, rain water bucket after the roof to collect rainwater to check the discharge tube wells.

According to the specification, the building of a class of high-rise buildings, outdoor fire hydrant water 30L / s, fire hydrant water 40L / s, fire duration 2h. Hydrant enrich the water column height 12m, hose length 25m, gun nozzle flow 5.16L / s, fire standpipe diameter is DN100. In the attic is provided a test fire hydrant, fire hydrant box each have a remote start the fire pump buttons.

The building wet automatic sprinkler system, sprinkler system design flow 40L / s. Alarm valve located in the basement of the pumping station, the layers are set flow indicator, end water apparatus and a signal valve, which signals are sent to the fire control center for processing. Selection box integrated fire booster pump regulator device (including 18 m3 fire water tank) Storage 10min initial fire sprinkler system, fire hydrant system, water, initial fire extinguishing water from the tank, the latter by a basement fire extinguishing pumps and spray pour water pump.

Keyword: water-supply system、drainage system、hydrant system、automatic sprinkler system、rainwater system
