摘要:本设计为苏州市水利局综合楼建筑给水排水设计。包括建筑给水系统、建筑排水系统、建筑消防系统、建筑热水系统的设计。

　　　该建筑东侧及南侧的城市道路旁，有一市政给水干管可做为该建筑物的水源，管径为DN300，常年资用水头为24米，与楼距离20米，管顶埋深1.5米。其中排水系统还包括雨水系统设计，消防系统包括消火栓系统和自动喷水灭火系统。建筑给水系统将本建筑物分成三个区，低区为依靠市政管网水压直接供水，中区和高区采用变频水泵供水方式，即用变频泵供水。排水系统采用污废水合流系统，污废水进入化粪池处理，建筑底层单独设置排水立管将污水排至化粪池。雨水系统采用重力半有压流系统。消防给水系统中的消火栓系统采用两股水柱同时到达。自动喷水灭火系统在办公室、走廊和客房布置。消防水池的体积为室内消防水量、喷淋系统水量和室外消防水量之和。热水系统中热源为建筑物附近的表压为0.20MPa的蒸汽热源。加热器采用半容积式水加热器。给水管材采用三型聚丙烯管（PP-R）管材，排水管道采用硬聚氯乙烯管（UPVC），消防管材选用钢管，热水管材选用交联聚乙烯（PEX）。

Abstract:The design for the Suzhou Municipal Water Conservancy Bureau Building Water and Drainage Design. Including building water supply systems, construction of drainage systems, building fire protection systems, building hot water system design.

　　　The building east and south of the city beside the road, there is a municipal water mains water can do for a building, diameter of DN300, perennial owned water head of 24 m and 20 m from the floor, the top tube depth 1.5 m. Stormwater drainage system which also includes system design, fire protection systems, including fire hydrant systems and automatic sprinkler system. Building water supply system of the building is divided into three zones, the lower zone is to rely on the municipal pipe network pressure direct water supply, the area and the upper zone to the pump tank water supply, which uses variable frequency pump water. Sewage and waste water drainage system merging systems, sewage and wastewater into the septic tank treatment, construction drainage bottom riser will be individually set to a septic tank effluent discharge. Gravity drainage systems using semi-pressurized flow system. Fire water supply system in the fire hydrant system uses two jets of water at the same time to arrive. Automatic sprinkler system in offices, corridors and rooms furnished. The interior volume of fire water fire water, water sprinkler system and outdoor fire water combined. Hot water system for the building near a heat source gauge pressure of 0.20MPa steam heat. Semi-displacement type water heater heater. Water pipe using three polypropylene tube (PP-R) pipes, drainage pipes using PVC pipe (UPVC), fire pipe use steel pipe, hot water pipe use cross-linked polyethylene (PEX).
