【摘要】：城市综合排水管网是解决城市内涝问题不可或缺的市政基础设施,是城市区域性经济发展的基石产业,并能够促进生态系统的有序循环。随着我国城镇化程度的不断提高,现有城市在不断扩大,原有城市排水系统不能满足需求,大量地面硬化及河道被侵占使得特大型城市排洪能力降低,下凹式立交桥在雨季形成积水重灾区。在大交通流状态下,积水影响道路通行能力,造成了交通拥堵等一系列问题。习近平总书记提出"加强海绵城市建设",国家财政部、住建部和水利部于2015年1月联合进行了海绵城市建设试点工作,确定第一批十六座试点城市名单,旨在构建自然积存、自然渗透、自然净化的新型城市,达到"小雨不积水、大雨不内涝、水体不黑臭、热岛有缓解"的城市建设目标。北京市为解决城市中心区下凹式立交桥内涝问题,在2012~2016年分三期对排水系统进行大规模改造,充分利用桥区周边的地下空间修建大断面雨水调蓄池,旨在通过"雨峰调蓄,错峰排流"。我集团参与建设了北京市桥区积水治理一、二、三期工程共计41项,在建设过程中通过不断总结开发利用地下空间的经验,形成了一套完善的雨水调蓄池综合技术,以供工程技术人员和类似工程参考。
[Abstract]:Urban comprehensive drainage network is an indispensable municipal infrastructure for solving urban waterlogging problems. It is the cornerstone industry of urban regional economic development and can promote orderly circulation of ecosystems. With the degree of China's urbanization continues to improve, the city continues to expand, the original city drainage system can not meet the demand, a large number of surface hardening and river encroachment made large city drainage capacity is reduced, the sunken overpass formed the hardest hit by the water in the rainy season. In the state of large traffic flow, water accumulation affects road traffic capacity and causes a series of problems, such as traffic congestion. The general secretary Xi Jinping put forward to strengthen the sponge city construction "the State Ministry of finance, the Ministry of housing and the Ministry of water resources in January 2015 jointly conducted the sponge city construction pilot work, identified the first batch of sixteen pilot city to build a new city list, natural accumulation, natural infiltration and natural purification, to achieve" no water, rain does not rain waterlogging, water is not black odor, city heat island has construction target relief ". Beijing city to solve the problem of waterlogging sunken overpass in the center of the city, in the 2012~2016 year three period of large-scale transformation of the drainage system, make full use of the bridge area surrounding the underground space construction of large section rainwater storage tanks, aims to "rain peak regulation, peak discharge". I participate in the construction of one or two water governance group, Beijing city bridge area three projects totaling 41, by constantly sum up the development and utilization of underground space experience in the construction process, has formed a set of perfect rainwater storage tank comprehensive technology for engineering and technical personnel and similar engineering reference.
