课 程 设 计 题 目： 学 院： 河南城建学院 专 业： 给水排水工程 姓 名： 学 号： 指导老师： 完成时间： 2014年6月12日  前言 我们水是人类生命的源泉，科学用水排水是人类社会发展史上最重要水位社会活动和生产活动内容之一，并且这次设计让我们更加了解城市給水排水体制和我们所需要的市政管网系统中应该满足那些要求，我们这次的初步设计让我们与上课的理论知识结合起来。让我们对市政管网有更深的了解。 通过这次设计也让我们对给排水管网的基础理论，基本知识与工程实际相结合起来，通过独立完成每一步的设计，从給水上的定线，然后通过最高日流量计算和消防及发生事故的校核这样是我们更加的与工程实际结合在一起对給水有更深的了解，对于污水和雨水方面我们通过选择管径，和计算埋深来说明所设计的污水和雨水管路的合理性，由于我设计的开封市的城市，污水管和雨水管采用分流制体系。由地形图可以看出开封市的城市地形是东北边高，西南边底，所以决定把污水厂设在城市的西南部，污水经污水厂处理后，排入河流，雨水直接排入河流和周边地势低洼湿地。  Preface Our water is the source of human life, the scientific use of water drainage is one of the history of the development of human society is the most important level of social activities and production activities, and this design let us know more about the city should satisfy the requirements of water supply and drainage system and we need the municipal pipe network system, the preliminary design we this time let us combine with theory knowledge class. Let us have a deeper understanding of the municipal pipe network. This design also let us the basic theory of the drainage network of the basic knowledge, combined with engineering practice, the design of each step is accomplished by independent, from fixed line feed on, check and then by the maximum daily flow calculation and fire and accident so that we more and engineering together with the deeper understanding of water supply, for sewage and stormwater we through the selection of pipe diameter, and calculate the depth to illustrate the rationality of the design of the sewage and rainwater pipeline, because of the design of the city of Kaifeng, sewage pipes and rainwater pipes using triage system. The topographic map can be seen in the Kaifeng city urban terrain is northeast high, southwest edge and bottom, so the decision to make the sewage factory is located in the southwest of the city, the se
