- Abstract:
- Based on the current sponge city design method of urban road in Jiaxing City, the pros and cons of the construction effects of different design methods are analyzed and comprehensively evaluated from the following five aspects: index completion, landscape effect, ease of construction, cost and operation maintenance. Multiple situations are well investigated, including the road cross section and the green space concessions. Moreover, according to the analysis results, this paper proposes the following technical optimizations on collecting, purifying and infiltrating rainwater, such as filter type inlet, multifunctional curb inlet, divider drainage culvert, and ecological tree belt. The proposed optimizations focus on water quality purification and water volume control, targeting to the status of typical cross sections, and provide a detailed design diagram and a good reference to sponge-city design methods for the urban road.
