随着我国城市化进程的不断加快,城市自然水文条件发生了明显改变,水的自然循环被人为割裂,暴雨内涝频发,对城市功能、社会秩序、资源与环境造成不同程度的破坏,直接影响城市整体形象的提升,甚至危及人们的生命及财产安全。随着2013年雨季的到来,城市的排雨系统建设也再一次引起各方的重视。2013年国务院办公厅下发了《关于做好城市排水防涝设施建设工作的通知》。《通知》提出,力争用5年时间完成排水管网的雨污分流改造,用10年左右的时间,建成较为完善的城市排水防涝工程体系。本文描述了我国的降雨情况以及面临的一些考验,并对天津市应对城市内涝做了梳理和阐述,最后,本文还针对天津市防治城市内涝提出了一些实践性建议。
With the accelerating process of urbanization in our country, the natural and hydrological conditions of cities have undergone obvious changes. The natural circulation of water has been artificially fragmented. The occurrence of frequent floods in the rainstorms has directly affected the destruction of urban functions, social order, resources and the environment. The overall image of the city to enhance, and even endanger people’s lives and property safety. With the arrival of the rainy season in 2013, the city’s rainwater system construction once again aroused the attention of all parties. In 2013, the General Office of the State Council issued the Notice on Doing Well the Construction of Urban Drainage Facilities. The “Circular” proposes to strive to complete the rainwater and sewage diversion transformation of the drainage network in five years and to build a relatively complete urban drainage and waterlogging prevention engineering system in about 10 years. This paper describes the rainfall situation in our country and some tests that we are facing. In the end, this paper reviews and elaborates Tianjin’s response to urban waterlogging. Finally, some practical suggestions are put forward to prevent and control urban waterlogging in Tianjin.
