【摘要】：2012年7月21日，北京城市遭遇了61年以来的最强的降雨。但由于各种原因导致城市排水系统并不能承受如此负荷，再加上管网运营管理不足等的原因，导致城内多处路面积水，对城市交通以及城市公共设施均造成了严重的影响，进而严重影响了城市居民正常的生活与工作。然而，近几年，类似事件在全国许多大中城市纷纷上演，“水上威尼斯”的场景屡屡发生。因此，本文便针对城市排水系统以及与其相关的一系列问题展开了研究。首先，，本文较为系统的研究了我国城市排水管网在规划、设计、施工、管理、水资源回收利用以及美化环保等方面存在的问题。提出了城市排水规划应结合城市的特点；管网设计应适当提高重现期；管网施工应采用先进的技术和设备；管网的综合管理应采用GIS等技术；水资源特别是雨水的回收利用应提高技术和规模；城市排水应保持美观和环保等基本对策。其次，通过归纳整理和理论研究，建立了现代城市排水设计、施工、管理的基本体系，给出了城市雨水、生活污水、工业废水、洪水的详细计算公式，介绍了排水管线的施工方法，在已有成果的基础上完善了城市排水管理综合管理体系，并建立了城市排污的应急管理系统。最后，以某城市为例对城市来水量的计算，管网的设计方法、步骤以及管网布置等各方面进行综合的示范性说明。
[Abstract]:On July 21, 2012, Beijing suffered its strongest rainfall in 61 years. However, due to various reasons, the urban drainage system can not bear such a load, coupled with the insufficient operation and management of the pipe network and other reasons, leading to many places in the city surface water, which has a serious impact on urban traffic and urban public facilities. And then seriously affected the normal life and work of urban residents. However, in recent years, similar events have been staged in many large and medium-sized cities across the country. Therefore, a series of problems related to urban drainage system are studied in this paper. First of all, this paper systematically studies the problems existing in the planning, design, construction, management, water resources recycling and beautifying environmental protection of urban drainage networks in China. It is pointed out that the urban drainage planning should be combined with the characteristics of the city, the pipe network design should increase the recurrence period properly, the advanced technology and equipment should be used in the pipe network construction, the comprehensive management of the pipe network should adopt the technology of GIS and so on. The recovery and utilization of water resources, especially Rain Water, should be improved in technology and scale, and the basic countermeasures of urban drainage should be kept beautiful and environmental protection. Secondly, the basic system of modern urban drainage design, construction and management has been established through induction, collation and theoretical research, and the detailed calculation formulas of urban Rain Water, domestic sewage, industrial wastewater and flood have been given. This paper introduces the construction method of drainage pipeline, improves the comprehensive management system of urban drainage management on the basis of the existing achievements, and establishes the emergency management system of urban sewerage. Finally, taking a city as an example, the calculation of urban water quantity, the design method, steps and layout of the pipe network are illustrated comprehensively.
