机荷高速公路立体复合改扩建工程水环境治理研究

Research on Practice of Water Environment Treatment in the Three-dimensional Composite Reconstruction and Expansion Project of JiHe Expressway

为探究城市高度建成区高速公路水环境治理问题,本文以深圳市机荷高速公路立体复合改扩建工程为例,论述了城市高度建成区高速公路水环境治理的困境,结合机荷高速公路不同区段径流及污染特征,确定基于海绵设施的水环境治理思路,规划设计了基于海绵城市理念的城市高度建成区水环境治理方案,为城市高度建成区高速公路水环境治理提供借鉴。

In order to explore the problem of water environment treatment of the expressway in the highly built-up area of the city,this paper takes the three-dimensional composite reconstruction and expansion project of Shenzhen JiHe Expressway as an example.First of all,the plight of expressway water environment management in highly built urban areas is discussed.Then,combined with the characteristics of runoff and pollution in different sections of JiHe Expressway,the idea of water environment treatment based on sponge facilities is determined.Finally,the water environment treatment plan for the urban highly built-up area based on the concept of sponge city was planned and designed,which can provide a reference for the water environment treatment of expressway in highly built areas of cities.
