Finally draw the sewage and rainwater pipe network pipe profile .Keywords: Sewage pipe network; rainwater pipe network ;hydraulic calculation 引言近年来,随着人们生活质量的不断提高,环保意识的不断加强,对生活用水的水质要求也越来越高,更多的人了解了污水是生活用水的主要污染源。在城市的市政系统当中,给水排水系统是非常关键的一个环节。其中,排水系统是直接关系民生的问题,由于污废水不及时排放或拥堵等原因,会给当地的环境造成很大污染，所以排水系统的设计格外重要。课程设计是学习计划的一个重要的实践性学习环节，是对前论、基本技能及专业知识的综合应用。通过课程设计调动了我们学习的积极性和主动性，培养我们分析和解决实际问题的能力，为我们走向实际工作岗
