地上十六层地下一层某大厦商住楼给水排水工程设计(含CAD图)

地上十六层地下一层某大厦商住楼给水排水工程设计(含CAD图)(任务书,开题报告,外文翻译,计算说明书19000字,CAD图21张)
摘    要
该工程的设计主要包括生活给水设计、消防给水设计、排水设计和喷淋系统设计。
给水系统分区供水，从市政管网上接一根DN65的引入管，负一层至地上四层为市政管网直供，五至十五层采用无负压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513立方米。建筑室内排水采用分流制，进入检查井后，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。雨水排放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。
 
Water supply and drainage engineering design of commercial building silver round building
Abstract
This building possesses for water draining water presses the high-rise construction to request for draining water to carry on the design.
Water supply system water, from municipal pipe network pick a service pipe DN65, minus one to four floors for the direct supply of municipal pipe network, six to fifteen layers with no negative-pressure variable-frequency water supply. Fire pool used for reinforced concrete structures placed in basement pumping station outside the effective volume 549 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, 40L/s fire hydrant water consumption, fire life 3h. 12m fire hydrant full water column height, hose length 25m, 5.16L/s water gun nozzle flow, fire the riser tube diameter DN150. 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 40L/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. Selection box-pump fire booster regulator device integration (including 20 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
Keyword: water-supply system、drainage system、hydrant system、automatic sprinkler system、rainwater system

本工程采用的设计方案为无负压给水方式。
据设计资料以及规范中的要求并结合该楼的功能分区，低区利用市政给水管网供水压力直接供水；高区采用无负压设备加压供水，设备机组设置在地下室水泵房。本设计采用高区每层均设减压阀的供水方式，采用Y型减压稳压阀。阀后压力在0.2MPa，使供水达到最大舒适度。
系统组成
建筑内部给水系统一般由引入管、给水管道、给水附件、给水设备、配水设施和计量仪表等组成。
