摘 要

本设计一层至地上三层为市政管网直供，四至十二层和十三至十八层为变频水泵水箱联合供水的给水方式。直供部分从市政给水管网接一根DN150的引入管，另两根DN100的引入管接至地下一层生活水池和消防水池。生活水池为装配式不锈钢生活水箱，消防水池采用砖砌混凝土结构，放置于地下室。排水采用生活污、废水合流制。泵房排水槽经汇集排至地下一层污水井，经潜污泵提升排至检查井再经过化粪池处理后排入市政排水管。建筑里所有给排水横管在吊顶内，将各单元生活污水管适当汇集转换到排水立管后排出室外。屋面雨水经屋面雨水斗收集后由雨水管排至地面作散水。

根据规范，该建筑为一类建筑，属中度危险一级。室内消防流量40L/s，室外30L/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、DN150。在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淋灭火系统，报警阀设于地下一层，各层均设水流指示器和信号阀，其信号均送入消防控制中心进行处理。各层均采用自动喷淋系统，地下一层采用下垂式喷头。各层均设末端试压装置以及放空管。本工程的自动喷水灭火系统分5个区。屋顶水箱为18立方米，，贮存有生活、10min自动喷水灭火系统用水量。自动喷水灭火系统和消火栓系统的初期灭火由水箱供水，后期供水由地下室的消防水泵和自喷泵供水，各支管与立管连接处设置减压孔板。

根据重力式雨水系统和虹吸式雨水系统的设计分析及造价对比后，本设计采用重力式屋面雨水排水系统。

Abstract

The this design 1 F go to ground previous three for municipal services tube the net keep provide, 4-12 F and 13-18 F is water pump water tank consociation supply water of 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 DN100 into tube connect to underground 1 F life pond and fire fight pond.Life the pond is a stainless steel life water tank, fire fight pond adoption the brick carve concrete structure and place outdoors.Drain an adoption life dirty, the waste water confluence system, ventilate tube in addition to 1-3 F drain outside and all adoption the appropriation ventilate to sign tube to ventilate.The pump house drain slot through gather together row to underground the 1 F sewage well, through Qian dirty pump promote row to check well again through septic tank processing rear row go into municipal services drain pipe.Building 4 F above of life the soil pipe is in the 3 F hang the crest, each unit life soil pipe appropriate gather together conversion to arrive drain to sign tube rear row outdoors.House noodles rain water through the house noodles rain water Dou after the collections from rain water tube the row go to the ground to make to spread water.

According to the norm, should building is a type of building, belong to medium degree dangerous one class.Indoor fire fight discharge 40 L/s, the outdoors 30 L/s.Enrichment water pillar take a 12 m and water dragon take length to take a 25 m, water gun spray the mouth discharge 5.2 L/s, and the fire fight sign a tube tube path for the DN100, DN150.Establish to experiment penstock 1 at the crest layer, all establish inside each indoor penstock box long-distance leave start fire fight pump of button.

Should building adoption wet type auto spray to pour to extinguish fire system, report to the police valve to establish in underground 1 F, each all establish water current indicator and signal valve, its signal all send into fire fight control centre to carry on processing.Each all adoption auto spray to pour system, underground 1 F adoption descend a hang type to spray a head.Each all establish bitter end to try to press equip and put empty tube.The auto of this engineering spray water to extinguish fire system cent 5 area.Roof water tank for 36 sign a square rice, is life fire fight suitable for use water tank, store to contain life, 10 min auto spray water to extinguish fire system, indoor penstock system to use water quantity.Auto spray water to extinguish fire system and penstock system of initial stage extinguish fire from the water tank supply water, empress period supply water from fire fight water in the ground floor pump with from spray pump supply water, each tube with sign tube conjunction place constitution decompression bore plank.

According to the design of the gravity type rain water system and the Hong absorb type rain water system analysis and after building price contrast, this design adoption the Hong absorb type house noodles rain water drain system, have rain water Dou little, sign tube little and horizontal mourn tube not demand slope, displacement and emissions speed quick etc. characteristics.(From profession unit design)

Keyword:the water supply system drain a system penstock system auto spray water to extinguish fire the system rain water system
