摘 要

给水系统分区供水，从市政管网上接一根DN50的引入管，负一层至地上四层为市政管网直供；五至十层为加压区，采用变频泵加压供水。建筑室内排水采用污、废水合流制，室外排水采用污废合流制，排入检查井后，再排入市政污水管网。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。建筑雨水采用外排水，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，该建筑为一类高层建筑，室外消火栓用水量20L/s，室内消火栓用水量30L/s，火灾延续时间2h。消火栓充实水柱高度13m，水龙带长度25m，水枪喷嘴流量5.42/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。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500立方米。

该建筑采用湿式自动喷水灭火系统，喷淋系统设计流量30L/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36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。

Water Supply and Drainage Design of an Agency Office of Bank

Abstract

Water supply system water, from municipal pipe network pick a service pipe DN50, he negative layer to the ground four Supplying municipal pipe network, five to fifteen layer is pressed a district, pressurized water pump with frequency. Architecture Indoor use sewage drainage, waste water confluence, outdoor drainage system using waste and sewage confluence, after checking into the well, and then discharged into municipal sewage pipe network. Basement drainage ditches pooled by row to the sump, the submersible sewage pump discharge to upgrade manholes. Building with external drain rainwater, choose gravity flow system half pressurized, rain water bucket after roofing the rainwater collection tube row to inspect wells.

According to the specification, the building of two types of high-rise buildings, outdoor fire hydrant water 20L / s, fire hydrant water 30L / s, fire duration 2h. Hydrant enrich the water column height 13m, hose length 25m, gun nozzle flow 5.42L / 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. Fire basin made of reinforced concrete structure, located on the outside basement pumping stations, the effective volume of 500 cubic meters.

The building wet automatic sprinkler system, sprinkler system design flow 30L / 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. Automatic sprinkler system of the project in two areas. Selection box integrated fire booster pump regulator device (including 36 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.
