1、 1 小区多层建筑给水排水工程设计 摘 要 本设计为小区多层建筑给水排水工程设计，设计的内容主要包括：建筑给水系 统设计，建筑排水系统设计，建筑雨水系统设计，消火栓给水系统设计，自动喷淋 系统设计。 本建筑地上 6 层加跃层，建筑总高度为 21.5 米，一层层高 3.6 米，二层层高 3.9 米，其余层高为 2.8 米。一层为商场，二层左侧为办公室，右侧为住宅，三层 到跃层为住宅。 小区给水水源采用市政管网给水，市政管网压力为 0.35Mpa,经管网水力计算， 采用管网直接供水和水箱联合供水方式。在完成管网布置后，通过计算确定室内给 水管网的管径、管内流速和管段水头损失，并选择的合适的加压水泵
2、、分户水表和 总水表。 排水方式选用污废水分流制排放的方式。直接排放进入小区污水管道，再排放 入城市下水道。确定生活排水系统布置形式并通过计算确定室内排水管网管径和坡 度。 雨水排水方式采用普通外排水方式。通过计算屋顶的汇水面积，确定了雨水管 的管径。 消防系统，住宅、办公室采用消火栓给水灭火系统，商场采用自动喷淋灭火系 统。 关键词： 给水系统；直接供水；普通外排水；自动喷淋 2 The Water Supply and Drainage Engineering Design of Anshan Jinfu Garden High-rise Residential Building Abst
3、ract The design is water supply and drainage engineering design of Anshan City Garden high-rise residential building. The content of my design includes the design of the building water supply system, the building water drainage system, the building storm-water system, the hydrant water supply system
4、 and the automatic sprinkler system. The present building on 6 floors with the thermocline, the building height of 21.5 meters, a layer of 3.6 meters high, two layers upon layer 3.9 meters tall, the layer is 2.8 meters high. A layer is a shopping mall, two floors and on the left for the office, the
5、right to housing, three layer to layer for residential. District water supply water source uses the municipal network water supply, the pressure of the municipal pipe network is 0.35Mpa, administered by the network hydraulic calculation, using direct water-supply pipe and tank joint water supply mod
6、e. At the completion of the network layout, determined by calculation of indoor water supply pipe system, the diameter of the flow velocity in the tube and tube water head loss, and select the suitable pressurized water pumps, individual water meter and total water meter. Drainage mode selects the way of sewage and waste water discharged in separation. Direct discharge into the sewage pipe, and then discharged into the city sewer. Determine the life water system layout and determined 3 through
