水岸家园商业大厦建筑给水排水工程设计.rar

摘要:此次设计为十五层商住楼的建筑给水排水工程设计，主要由以下四个系统部分组成。

　　　建筑给水系统采用分区供水，一到三层为低区，由市政管网直接供水；四层到十五层为高区，采用水泵-水箱联合供水。水箱的有效容积为1.44m³，水池的有效容积为13.5m³。

　　　建筑消防系统主要采用室内消火栓系统，火灾初期10min消防用水量由楼顶消防水箱供水，消防水箱的有效容积为18m³，消防水箱的水由消防水泵从消防水池抽取；10min后从消防水池抽水供消火栓使用，消防水池设置在室外，水池的有效容积为288m³。一楼至三楼的电梯前室及走廊设自动喷水灭火系统。消火栓系统和自动喷水灭火系统均采用钢管。

    建筑排水系统：本建筑各层公共卫生间采用生活污水和生活废水合流制排放。由于楼层较高，2~15层共同排水，一层单独排水。厨房的废水、卫生间的污水经化粪池处理后排入市政排水管网，仅设伸顶通气立管。排水立管采用消音螺旋排水塑料管，其余采用UPVC塑料排水管。

　　　建筑热水系统采用闭式机械循环系统，热水的分区系统同冷水系统；采用集中热水供应，热源来自市政热媒管网（0.20MPa），冷水经过容积式水加热器加热后供向配水管网。热水管材采用交联聚乙烯管。

Abstract:This design is the construction of 15 floor water supply and drainage design, including the building water supply system,mainly by the following four system parts. 

　　　Building water supply system using zoning water supply , 1 to 3 floor are low area by the municipal water supply pipe directly; 4 to 15 floor is high areas.The water tank for effective volume 1.44 cubic meters, pool of effective volume for 13.5 cubic meters. 

　　　Building fire system mainly adopts laboratory fire hydrant system , 10 min fire early fire from the roof water supply fire tank ,the water tank of effective volume for 18 cubic meters; 10 min after the fire started fire pumps, pumping water from a fire hydrant available for use. the water pool of effective volume for 288 cubic meters. The first floor to third floor are shops, 4 floor above the house before the elevator room and a corridor sprinkler systems. Fire hydrant system and automatic sprinkler system is using steel tube. 

    Building drainage system: toilet uses sewage, wastewater by combined drainage system, kitchen waste water discharge all alone,ground floor drain alone, the kitchen waste water, toilet of sewage treatment by the septic tank back into the municipal drainage pipelines. Only set top ventilation stand pipe.The spiral drainage pipe deadened the plastic pipe. 

　　　Building hot water system adopts closed mechanical circulation system, a division system of hot water with cold water system; The focus on hot water supply, heat source from the municipal HTM pipeline network (0.20 MPa), cold water after volumetric heat the water heater for water distribution network to after. Hot water pipe using cross linked polyethylene pipe.
