1、《给水排水管网系统》课程设计计算说明书题目:衡阳市给水排水管网工程学院:市政与环境工程学院专业:给排水科学与工程姓名:孔庆培学号:026413158指导老师:谭水成完成时间:2015年12月30日前言衡阳市给水排水管道工程设计,其市总人口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
2、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。PrefaceThedesignofwatersupplyanddrainagepipelineengineeringofHengyangcity,thetotalpopulationofthecityis543,200around,thereareafactory“A”andatrainstationinthecity.Th
