摘要:本设计为徐州泉山区宜家庭院建筑给水排水工程设计 。徐州泉山区宜家庭院为21层民用建筑，地下两层分别为储藏室和车库，地上为住宅。此外，屋顶设有阁楼间。其中地下室每层层高为2.7m,地上顶层层高为3.1m,其余每层层高为2.9m，总层高64m。

　　　设计主要包括对建筑内的给水排水工程以及与之配套的室内外部分给水排水工程的设计,具体包括:建筑室内给水系统、建筑热水系统、建筑消防系统、自动喷洒系统、建筑排水系统以及建筑雨水系统。

　　　在给水系统的设计中，采用分区给水的方式。1—3层为底层，4—15层为中层，16—21层为高层。底层，采用室外官网直接供水，中、高层均采用水泵和水箱联合供水及下行上给的供水方式。

　　　该建筑为高层住宅建筑，按照高层民用建筑防火规范，消火栓宜布置在明显、经常有人出入且使用方便的地方，因而在该建筑的房间走廊中，电梯的前室以及地下室中均布有消火栓。其中屋顶水箱应贮存火灾初期10min的消防水量。该建筑危险等级为中危险级Ⅰ级，采用湿式自动喷水灭火系统。

　　　在排水系统的设计中，卫生间采用污、废水分流制，厨房采用废水单独排放，卫生间的污水经化粪池处理后排入市政排水管网，厨房及卫生间的废水直接排入市政排水管网。雨水采用内排水系统，雨水设专门的雨水立管排入市政雨水管道。

　　　热水系统采用全循环的系统，高区低区均为上行下给的布置形式。最不利点水温大约为60℃，管道中水温在60℃—70℃之间。建筑热水系统采用循环水泵供水系统，采用集中热水供应，热源来自市政热媒管网（0.20MPa）。

Abstract:Design the design for the Xuzhou District IKEA courtyard building water supply and drainage engineering. Xuzhou Quanshan area suitable for a family of 21 layers of civil building, two floor underground are storage room and garage, land for residential. In addition, the roof with attic. The basement of each layer is 2.7m, and the top layer is 3.1m, the rest of each storey is 2.9m, the total height is 64m.

　　　The design mainly includes the construction of water supply and drainage of buildings and design, complete with indoor and outdoor part of water supply and drainage engineering including: indoor water supply system, hot water system, fire system, automatic sprinkler system, drainage system and building drainage system.

　　　In the design of water supply system, using the water way. 1 - 3 layer to the bottom, 4 - 15 for the middle, 16 - 21 layer is tall. Bottom, the outdoor water supply in high-rise official website directly, a water pump is adopted, and the tank joint water supply and down to the water supply, water supply reliability, energy saving.

　　　The building is a high-rise residential buildings, according to the code for fire protection of high-rise buildings, fire hydrant should be placed in prominent, often have access and convenient place, so the building room corridor, there is a fire hydrant elevator lobby and uniformly distributed in the basement. The roof tank fire water storage of 10min at the initial stage of fire. The building risk rating for the dangerous level Ⅰ, using wet automatic fire-extinguishing sprinkler system.

　　　In the design of the drainage system, toilet using sewage, waste water diversion system, with separate toilet kitchen wastewater discharge, wastewater is treated in the septic tank is discharged into the municipal sewer, kitchen and toilet wastewater directly discharged into the municipal sewer system. The rain with internal drainage system, rain rain rain set special riser pipe in municipal into.

　　　Hot water system adopts system of full circulation, low area high are layout to the uplink. The most unfavorable point temperature is about 60 ℃, the pipeline temperature between 60 ℃ - 70 ℃. Building hot water system adopts the circulating water pump water supply system, centralized hot water supply, heat from the municipal HTM pipeline (0.20MPa).
