摘 要
本设计一层至地上五层为市政管网直供,六至十一层为变频泵供水的给水方式。直供部分从市政给水管网接一根DN150的引入管,另两根DN150的引入管接至地下生活消防水池。生活水池和消防水池采用砖砌混凝土结构。排水采用生活污、废水合流制。通气管均采用专用通气立管通气。屋面雨水排放选择重力式雨水系统,雨水经屋面雨水斗收集后由雨水管排至检查井。
根据规范,该建筑为二类建筑,属中度危险一级。室内消防流量20L/s,室外20L/s。充实水柱取12m,水龙带长度取25m,水枪喷嘴流量5.2L/s,消防立管管径为DN100。
该建筑采用湿式自动喷淋灭火系统,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。屋顶水箱为18立方米为消防水箱,贮存10min自动喷水灭火系统、室内消火栓系统用水量。自动喷水灭火系统和消火栓系统的初期灭火由水箱供水,后期供水由地下的消防水泵和自喷泵供水。

Abstract
In this design,on the 1F to the 5F for municipal services tube the net keep provide,6F to 11F is frequency conversion water supply pump as the water supply way. Keep provide part the net connect lead of a DN150 into the tube from the municipal services water pipe,another two lead of DN150 into tube connect to life and fire fight pond. Life pond and fire fight pond adoption the brick carve concrete structure . Drainage using domestic sewage and wastewater combined system. The drainage system is used specific vent stack. House noodles rain water through the house noodles rain roof drain after collection from rain water tube the row go to the check well.
According to the codes,the building is class one secondproof construction,belongs to one class of medium degree dangerous. Indoor fire fight discharge is 20 L/s and outdoor is 20 L/s,full water spout is 12m,hoses is 25 m,water gun spray the mouth discharge is 5.2 L/s,and the fire standpipe diameter is DN100.
The building is arranged with wet pipe fire sprinkler system. The floor should set a flow indicator,End water-test equipment and signal valve,its signal all send into fire fight control center to carry on processing. The fire tank is 18 cubic meters,have 10min fire water storage. Automatic sprinkler system and hydrant system of initial stage extinguish fire from the water tank supply water. Latter water supply is supply by fire pump and spray pump in the basement.
