《给水排水管网系统》课程设计 说明书 题 目： 学 院：市政与环境工程学院 专 业：给排水工程 姓 名： 学 号： 指导老师：完成时间：201年月30日 54.32万左右，有一工厂A和火车站。总设计时间为2周，设计内容主要是给水管道的定线、水力计算及部分区域的污水、雨水设计，并作出平面图和纵剖面图。 设计过程中，先大致了解衡阳市地形分布后，决定通过分区供水满足整个城市的用水需求。定线，给水水力计算，确定管径，校核等等，把定下的管径标图并整理报告。考虑城市初步规划，以及资金投资问题，采用完全分流制排水系统。生活污水和工业废水通过污水排水系统送至污水处理厂，经处理后再排入水体。雨水是通过雨水排水系统直接排入水体。 课程设计让我们结合所学知识，运用CAD制图，画出衡阳市给水排水管道总平面分布图，部分污水干管剖面图,学会灵活运用知识。 Preface The design of water supply and drainage pipeline engineering of Hengyang city , the total population of the city is 543，200 around,there are a factory “A” and a train station in the city. The total time of the design for 2 weeks, the content of the design is mainly about the water supply pipeline alignment, hydraulic calculation and the sewage of part of area, rainwater design, and make the plane figure and profile. In the design process, first understand topographic distribution of Hengyang city roughly, decide to meet the whole city water demand by the district water supply. Fixed line, calculation, to determine the water hydraulic diameter, checking and so on, to set the diameter of plotting and finishing the report. Considering the preliminary planning of the city, and the problem of capital investment, using completely separate drainage system. Domestic sewage and industrial wastewater is sent to the sewage treatment plant through the sewage system, and then discharged into the water body after the theatment. The rain water is directly discharged into the water body through rainwater drainage system. Curriculum design allows us to combine the knowledge which we have learned, the use of CAD drawing, drawing a distribution map of general layout of water supply and drainage pipeline in Hengyang City, part of the sewage trunk pipe profile, learn to use knowledge flexibly. 目录 1 设计任务 1 1.1 设计原始资料 1 1.2 课程设计内容 1 2 一区给水管网设计与计算 3 2.1 供水方式的选择 3 2.2 基本数据的确定 3 2.3 设计用水量计算 3 2.3.1居民综合生活用水 3 2.3.2.工业用水量 4 2.3.3
