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
2、内流速和管段水头损失，并选择的合适的加压水泵、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84TheWaterSupplyandDrainageEngineeringDesignofAnshan
