- Abstract:
- Taking the road reconstruction of Lingang new-city district in Shanghai, the pilot area of sponge city construction as the research object, we introduced the design methods of catchment division, rainwater drainage organization, sponge facility regulation and storage capacity calculation, biological retention zone, permeable pavement and ancillary facilities in the process of sponge city construction. The reconstruction road was designed according to the 65% annual total runoff control rate, and the actual operation effect was monitored after the completion of the project. The results showed that the actual total runoff control rate reached 96.3%, and the runoff pollutant removal rate reached 79%. The design scheme could meet control target requirements of sponge city, and provide references for similar projects.
