摘要:本设计是南通市星海紫郡综合楼建筑给水排水工程设计,该商住楼共17层，其中1～3层是商业用户，4～17+1层是住宅，主要包括建筑给水系统、建筑排水系统、建筑消防系统、建筑热水给水系统四个部分。

建筑给水系统：采用分区给水方式，结合本设计给出的建筑层高条件及市政管网提供24米的稳定水压的条件，将该建筑分为3个供水区，低区1～3层，中区4～13层，高区14～17（+1)层。低区采用市政水压直接供水，中区和高区采用水泵水箱联合供水的方式，机组设置在地下室。

建筑排水系统：采用污、废水合流制，设通气管。污水和雨水分别设置立管，污水经过化粪池处理后排入市政管网中，雨水、废水直接排入市政管网中。

建筑消防系统：本建筑为商住综合楼，1～3层是商铺，4～17层是住宅，故需采用自动喷淋灭火系统和消火栓灭火系统，建筑防火等级为中危险Ⅰ级。

建筑热水系统：采用半容积式水加热器，分区情况与冷水系统一致，热水系统统一供给的蒸汽热源0.20MPa。

设计中涉及到的管道布置、计算与安装及设备选型，均应遵循相关规范的要求，力求经济合理，简洁高效。

Abstract:This design is purple, Nantong Xinghai County Comprehensive Building Construction Plumbing engineering design, a total of 17 floors of the residential and commercial, in which 1 to 3 storey commercial users, 4 to 17 + level is residential, including building water supply systems, construction of drainage systems, building fire protection systems, building water supply system of four parts.

　　　Building water supply system: water partition mode, combined with the design conditions and given storey building offers 24 meters of municipal pipe network water pressure stable condition, the building is divided into three supply zones, the lower zone 1 to 3 layers, District 4 to 13 layers, the upper zone 14 to 17 (+1) layer. Low pressure area will adopt the municipal water supply directly, Central District uses the water pump and the high water tank combined approach, the crew set up in the basement.

　　　Building drainage system: sewage, wastewater combined system, set up through the trachea. Sewage and rainwater were set risers, septic tank treated sewage has been discharged into the municipal pipe network, water, waste water directly into the municipal pipe network.

　　　Building Fire System: The construction of residential and commercial complex, 1 to 3 layers of shops, 4 to 17 storey residential, it requires the use of automatic sprinkler systems and fire hydrant systems, building fire danger rating in grade Ⅰ.

　　　Building hot water system: semi-displacement type water heaters, partitioning consistent with the cold water system, hot water system, a unified supply steam heat 0.20MPa.

　　　The pipeline involved in the design layout, equipment selection and calculation and installation, are the corresponding design principle, seek economical, simple and efficient.
