大连某开发区综合商业楼给排水设计
[摘要]本设计为大连某开发区综合商业楼给排水设计，主要包括室内给水系统、排水系统、消火栓给水系统和自动喷水灭火系统四部分。室内给水系统采用分区供水，地下二层至地上六层为低区，第七层至第十六层为中区，第十七层至第二十七为高区。各区均以下行上给的给水方式，采用变频调速泵并联供水；室内排水系统采用采用合流制，生活污水、废水经化粪池处理后排入市政污水管网；消火栓给水系统分两个区，地下二层至地上十二层为低区，第十三层至第二十七层为高区。室内消火栓用水量为40L/s，每根竖管最小流量15 L/s，每支水枪最小流量5 L/s，火灾延续时间按3h计；自动喷水灭火系统喷头设计喷水强度，作用面积160，喷头工作压力0.10MPa。

Water Supply and Drainage Design of a Comprehensive Commercial Building in a Development Zone in Dalian
[Abstract]This design is for the water supply and drainage of a comprehensive commercial building in a development zone in Dalian.It mainly includes four parts:indoor water supply system,drainage system,fire hydrant water supply system,and automatic sprinkler system.The indoor water supply system adopts partitioned water supply,with the underground second floor to the sixth floor as the low area,the seventh to sixteenth floors as the middle area,and the seventeenth to twenty-seventh floors as the high area.The water supply method for each district is to use parallel connection of variable frequency speed control pumps for water supply,which is provided from the lower row to the upper row;The indoor drainage system adopts the combined system,and the domestic sewage and waste water are discharged into the municipal sewage pipe network after being treated in the septic tank;The fire hydrant water supply system is divided into two zones,with the lower zone from the second underground floor to the twelfth above ground floor,and the higher zone from the thirteenth to the 27th floor.The water consumption for indoor fire hydrants is 40L/s,with a minimum flow rate of 15 L/s for each vertical pipe and 5 L/s for each water gun.The fire duration is calculated as 3 hours;The design of the automatic sprinkler system nozzle has a water spraying intensity,a working area of 160,and a working pressure of 0.10MPa.
