基于LID的天津市立交桥附属空间雨水综合利用研究——以卫昆桥为例

Research on Comprehensive Utilization of Rainwater in Auxiliary Space of Tianjin Overpass based on LID, Take Weikun Bridge as an Example

文章针对立交桥附属空间雨水资源浪费和桥面雨水径流污染的生态与环境问题,提出了其景观构成要素组合串联条件下,对雨水资源进行回收再利用的解决思路。首先以天津市立交桥附属空间雨洪现状为基础,分析了其雨水资源再利用的潜力,然后采用LID技术,构建雨水综合利用系统,最后以卫昆桥为例,阐明景观构成要素组合条件下的雨水综合利用系统的LID设计思路,为立交桥附属空间雨水综合利用的LID设计提供了借鉴。

Aiming at the ecological and environmental problems of rainwater waste in the ancillary space of an overpass and rainwater runoff pollution on the bridge deck, this paper proposes a solution to the recovery and reuse of rainwater under the condition of combination of landscape components. Firstly, based on the current situation of rainwater in the ancillary space of Tianjin overpass, the potential of rainwater reuse is analyzed, and then LID technology is used to discuss the construction mode of rainwater comprehensive utilization system. Finally, Weikun Bridge is taken as an example. It clarifies the LID design idea of the rainwater comprehensive utilization system under the combination of landscape elements, and provides a reference for the LID design of the rainwater comprehensive utilization in the auxiliary space of the overpass.
