B市碧桂园建筑给水排水工程设计.rar

摘要:本设计是徐州碧桂园建筑给排水工程设计,该住宅为二十层，主要包括室内生活给水系统、室内消防给水系统、室内排水系统、室内热水给水系统四个部分。

　　　生活给水系统：采用分区给水，共计两个区。一层至四层为低区，由市政管网直接供水。五至二十层为高区，采用水池、水泵、水箱联合供水。

　　　消防系统：采用消火栓给水系统，室内消火栓给水系统采用临时高压给水，由消防水池、加压泵、供水管、阀门、室内消火栓等组成。火灾初期10min的用水量由屋顶消防水箱供给，正常供水由消防水泵从贮水池内抽取。

　　　排水系统：采用污、废水分流制，每个卫生间和厨房都设一根排水立管，卫生间的污水在底层汇合后进入化粪池再排入北边的市政排水管网，厨房的废水在底层汇合后进入隔油池，排水系统仅设伸顶通气管。

　　　热水系统：采用封闭式机械循环热水系统，通过蒸汽热源间接加热。分区情况与冷水系统一致，低区通过市政管网水压直接供水，高区通过高位水箱的压力，再加热水箱出水口外加一个水泵往上供水。

　　　给水系统和热水系统均采用PPR给水管材，排水系统采用UPVC排水管，消火栓给水系统采用热镀锌钢管。

Abstract:This design is Xu Zhou country garden building water supply and drainage engineering design, the residential is twenty layer, mainly including indoor living water supply system, indoor drainage system, fire water system and the indoor hot water supply system in four parts.

　　Living water supply system: the water division, a total of two area. One to four layers is low area, directly by the municipal pipe network of water supply. Five to twenty layer is high area, USES the pool of water, water pump, water tank joint water supply.

　　Fire control system: adopting the fire hydrant water supply system, indoor fire hydrant water supply system USES temporary high pressure water supply, the fire tank, pump, pipes, valves, an indoor fire hydrant, etc. Early fire 10 min by roof water tank of water supply, the normal water supply by fire pump from extraction from the reservoir.

　　Drainage system: the sewage, waste water diversion system, each toilet and kitchen set drainage riser, a piece of toilet wastewater after the underlying join into the septic tank and then discharged into municipal drainage pipe network, on the north side of the kitchen waste water after the underlying join into the separation tank, drainage system only a roof ventilation tube.

　　Hot water system: a closed mechanical circulating hot water system, indirect heating by steam heat source. Partition is consistent with cold water system, low area through the municipal pipe network water pressure water directly, high area by high pressure water tank, then heat the water tank water outlet and a water pump up.

　　Water supply system and hot water system adopt PPR water supply pipes, drainage system uses UPVC drainage pipe, fire hydrant water supply system using hot dip galvanized steel pipe.
