摘要:本设计建筑为一个20层的商业办公楼,给水排水工程的设计包括生活给水系统设计,排水系统设计,热水系统设计,室内消防给水系统设计。生活给水系统分区分为三个区,一至四层为低区,五至十二层为中层,十三至二十层为高层,利用地下室泵房变频泵供水。

消防系统分为消火栓系统和自动喷淋灭火系统,本建筑为一类民用建筑,而建筑高度≥50m,按《高层民用建筑防火设计规范》规定,室内消火栓用水量和室外消火栓用水量分别取30L/s和20L/s,自动喷淋系统用水量取30L/s,自动喷淋系统在屋顶设增压设备。

排水系统采用污废合流制,排水系统采用伸顶通气单立管排水系统,通气冒高出屋顶1m。

热水系统选择集中热水供应方式,以附件蒸汽热源作为热源,热水供应方式为:采用集中热水供应系统、间接加热方式、开式、全天热水供应系统。

给水系统采用PP-R给水管材,消火栓给水系统和自动喷淋灭火系统采用热镀锌钢管,排水系统采用硬聚氯乙烯(U-PVC)排水塑料管,粘接连接,热水系统横干管及立管采用钢衬塑复合管,做保温,室内横支管采用给水聚丙烯(PPR)热水管。在地下室设置贮水池和加压泵房,地下室另设集水坑,集水坑中设潜污泵,保证污水及时排出。

Abstract:The design and construction of a 20 layer of commercial office buildings,water supply and drainage engineering design includes the design of water supply system,drainage system,hot water system design,the design of indoor fire water supply system.Life water supply system partition is divided into three zones,one to four layers as low area,five to twelve for the middle,thirteen to twenty layers of high-rise,the basement pump water supply pump.

Fire protection system is divided into fire hydrant system and automatic sprinkler system,the construction of a class of civil construction,and the height of the building is greater than or equal to 50m,according to the"Regulations"code for design of fire system of high rise civil buildings,indoor and outdoor fire hydrant,fire hydrant water consumption were 30L/sand20L/s,automatic sprinkler system water 30L/s,automatic sprinkler system pressurized equipment on the roof.

Drainage system using sewage waste sewage system,drainage system with ventilating single stack drainage system,ventilation at high roof 1m.The hot water system of central hot water supply mode,to annex the steam as the heat source as the heat source,the hot water supply mode: the centralized water supply system,in direct heating mode,open,24-hour hot water supply system.

Water supply system adopts PP-R water supply pipe,fire hydrant system and automatic sprinkler system use shot galvanized steel pipe,drainage system with rigid polyvinyl chloride(U-PVC)plastic drain pipe connection adhesive,hot water system,horizontal trunk pipe and vertical pipe with steel lining plastic composite pipe,heat insulation,indoor horizontal branch pipe with water of polypropylene(PPR)pipes for hot water.Storage pool in the basement and the pressure pump,the basement a sump,sump is arranged in the submersible sewage pump sewage discharged timely,ensure.

Keywords:fire protection system of building  water supply system  drainage system   hot water system
