摘要:徐州市交通局商住楼是一栋14层的综合性民用建筑，该建筑包括一层地下车库、三层商铺以及若干层住宅。本次设计的主要内容即完成该建筑的建筑给排水工程设计工作。

　　　此次设计的主要内容包括：1）给水系统：包括室内外的冷水给水系统。2）热水系统：包括住宅淋浴用水等。3）排水系统：包括生活污废水系统、雨水系统。4）消防系统：包括消火栓系统和自动喷淋系统等。

　　　给水系统由外围市政给水供水管网提供水源，根据市政管网常年资用水头将本建筑给水分区分为低区与高区，分别由市政管网直接供水以及高位水箱减压阀减压供水。

　　　热水系统根据给水分区进行供水，热水由该建筑旁表压为0.20Mpa的蒸汽热源提供。

　　　排水系统根据本建筑的污废水成分，拟采用污废水合流制的排水方式，集中排放到化粪池中处理，之后排入市政排水管网。雨水系统采用重力流排水方式，直接将雨水排入市政管网。

　　　消防系统按照高层建筑“自救为主”的原则，根据高层建筑防火设计规范进行设计，室内外消火栓布置以及自动喷淋系统的设定均严格按照防火规范进行。

Abstract:Xuzhou Communications Bureau Rent All Serviced Apartments is a 14-storey integrated civil construction of the building, including a layer of underground garage, three shops and several layers of residential. The main content of the design is to complete the construction of the building Water and Wastewater Engineering design work.

　　　The main content of the design include: 1) water supply systems: the cold water supply system, including indoor and outdoor. 2) The hot water system: including residential shower water. 3) drainage systems: the sewage and waste systems, the rainwater systems. 4) Fire System: including hydrant systems and automatic sprinkler system.

　　　Municipal water supply system from the periphery to provide water supply pipe network, according to the municipal water pipe network perennial owned the building water partition head will be divided into low areas and high areas, respectively, by the municipal pipe network water supply tank valve and high pressure water.

　　　Hot water system based on water partition water, hot water by the side of the building steam gauge pressure of 0.20Mpa to provide a heat source.

　　　Drainage system in accordance with the construction of the sewage effluent composition, the proposed combined system of sewage and waste water drainage patterns, concentrated discharge to septic tank treatment, then discharged into the municipal sewer. Rainwater system uses gravity flow drainage patterns, rainwater directly into the municipal pipe network.

　　　High-rise building fire protection system in accordance with the "self-based" principle, according to the high-rise building fire safety design specifications for the design, layout, and indoor and outdoor fire hydrant sprinkler system settings are carried out in strict accordance with fire safety regulations.
