给水排水管道系统课程设计3·要领.doc

《给水排水管道系统》 设计说明 系 ? 别： 专 业：给水排水指导教师：实习时间： 河南城建学院 2013年12月25日 前 言 本次给排水管道的实习课程是对杭州市给排水管网进行设计，实习时间为两周，结合实际设计，使同学们对管道设计的知识和注意事项有更深刻的理解。 随着城市化进程的加快，给水排水工程已经发展成为城市建设和工业生产的重要基础设施，成为人类健康安全和工农业科技与生产发展的基础保障。给水排水系统是为人们生活、生产、市政和消防提供用水和废水排除设施的总称。给水排水工程由给水工程和排水工程两大部分组成。本设计针对这两部分对杭州市给水排水管道进行设计。 设计过程中，先大致了解杭州市地形分布后，决定通过分区供水满足整个城市的用水需求。定线，给谁水力计算，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，画出杭州市给水排水管道总平面分布图，部分污水干管剖面图，及给水等水压线图等，学会灵活运用知识。 Preface The water supply and drainage pipeline of practice course is on water supply and drainage pipe network in hangzhou city design, practice time for two weeks, combined with the actual design, make the students knowledge of pipeline design and matters needing attention to have a more profound understanding. With the speeding up of urbanization, water supply and drainage engineering has become the important foundation of the urban construction and industrial production facilities, become a human health safety and the basis of industrial and agricultural production and development of science and technology. Water supply and drainage system is for peoples life and production, municipal and fire the floorboard of the ruled out water and wastewater facilities. Water supply and drainage engineering is composed of two most of the water supply and drainage engineering. This design for the two parts of hangzhou city water supply and drainage pipeline design. The design process, first a general idea of hangzhou topography distribution, decided to meet the demand of the whole city water supply by partition. Who alignment, hydraulic calculation, to determine the pipe diameter, check, etc., the set of pipe diameter plotting and finishing report. Considering the preliminary planning, as well as capital investment, adopt completely separate system and drainage system. Life sewage and industrial wastewater by sent to the
