1、 前言 毕业设计是本科四年学习计划的最后一个重要的实践性学习环节，是对前期 所学基础理论、 基本技能及专业知识的综合应用。 毕业设计使我们具备调查研究、 文献检索、综合分析及总体规划设计和细部深入设计的能力，对学科发展新动向 有所了解。 校外设计跟校内设计又有了很大的区别， 校外设计更加接近实际工程， 运用的 知识更加专业化。对设计的工程项目应该考虑的方面更加全面，包括经济，现有 地形，施工难易程度等。因此校外设计是对我很好的锻炼。 我以古贤镇工横二路排水设计这个项目为设计题目。古贤镇工横二路全长 1760 米，机动车道宽 21 米，人行单侧宽 3 米，人行道为土路肩，雨水污水的埋设 均设在土
2、路肩下。设计时雨水污水采用完全分流，雨水管道在道路左侧，污水管 道在道路右侧。 雨水排入现状沟渠， 污水由污水管引到污水处理厂进行处理排放。 设计内容主要包括，雨污水管道的管径，埋深，坡度，出图为施工图。 Preface Graduation is a four-year undergraduate study program of the last hands-on learning is an important aspect, is a pre-learned basic theory, basic skills and professional knowledge in integra
3、ted application. Graduation will enable us to research, document retrieval, and comprehensive analysis of the overall planning, design and detail design in depth the ability of the new trends in the development of an understanding of discipline. Design in school and outside school has a great deal o
4、f difference The design outside closer to the actual project, it will use more specialized knowledge. The design aspects of the project should consider more comprehensive, including economic, existing topography, construction degree of difficulty. Therefore campus design is a good exercise for me. G
5、u xian town cross road drainage, I designed this project to design topics. Cross road, guxian town of 1760 metres in length, motorway 21 meters wide, pedestrian single sided 3 m wide, dirt shoulder of the pavement, rainwater sewage buried is located in soil under hard shoulder. Design a fully shunt
6、rainwater sewage, rainwater pipes left side of the road, sewage pipes in the road on the right. Rainwater into the status quo ditches, sewage from the sewage pipes lead to the sewage treatment plant emissions. Design elements include, rain sewers diameter, depth, slope, the picture shows the construction plans. 目录 第一章第一章 绪论绪论 1 1.1 任务依据 1 1.2 勘测简况及质量控制 1 1.2.1 测设阶段 1 1.2.2 测设经过 1 1.3 工程概况 1 1.4 道路设计标准 1 1.5 路线 2 1.5.1 路线方案 2 1.5.2 纵断面设计主要控制点和设计原则 2 1.5.3 路拱坡度 2 1.5.4 设计高程 2 第二章第二章 排水设计说明排水设
