某综合楼建筑给水排水工程设计(含CAD图)(任务书,开题报告,外文翻译,设计说明书20000字,CAD图20张)
摘 要
本建筑工程为某商业大楼,给水系统分区供水,地下负一到地上三层为低区,由市政管网直接供水,四层到八层为高区,采用一组调速泵供水。生活排水采用污、废水合流制,一二层为商业部分,污水排水立管在二层的吊顶自排水横干管汇集到主立管再引出至室外污水井;三层及以上楼层为办公写字楼,休息室卫生间排水各层通过排水横管排至立管,由立管汇集至下;地下室内雨污水通过地下排水渠汇集至集水坑,由集水坑内污水提升泵加压提升,排至室外污水管道。屋面雨水排放选外排水排放方式,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淋灭火系统,报警阀设于地下一层,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。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,后期供水由地下室的消防水泵和自喷泵供水。

Abstract
The construction project is a commercial building, water system zoning water, underground negative one to three layer for low area, by the municipal water supply pipe network directly, four to eight layer for the area, using a set of variable speed pump water supply. Life drain the sewage, wastewater confluence, a two-story as part of the business, sewage drainage riser in the second layer of the ceiling from horizontal drainage dry collection pipe to the main vertical pipe and then leads to outdoor sewage well; three layer and above the floor for office office, room toilet drainage layers by horizontal drainage pipe row to riser, consists of a riser is collected to the next; in the basement of the rain sewage by subsurface drains together to the sump and the puddle of sewage lifting pump pressure lifting, discharged to the outdoor sewage pipe. Roof drainage drainage discharge mode selection, the rainwater collected from the roof drain rain water pipe row to check well.
According to the specification, the building is the second class of high-rise buildings, outdoor fire hydrant water 20L / s, indoor fire hydrant water is fire continue time 2H. The fire hydrant to enrich the water column height 12M, length 25m hose, gun nozzle flow 5.16L/s, riser diameter is DN100. On the roof floor test a fire hydrant, fire hydrant box each are equipped with remote start the fire pump button.
The building adopts wet automatic sprinkler system, alarm valve is located in the ground floor, each layer has a water flow indicator, the end of the test water device and signal valve, the signal is sent to the fire control center for processing. The automatic water spraying fire extinguishing system in this project is divided into 2 zones. The roof water tank of 18 cubic meters for the fire water tank, fire water storage 10min automatic sprinkler system, indoor fire hydrant system. Automatic sprinkler system and fire hydrant system of early fire extinguishing by water supply and post water from the basement of the fire pump and sprinkler pump water supply.
