城市道路海綿城市設計的建設效果評價及設計優(yōu)化
- Title:
- Construction Effect Evaluation and Design Optimization of Urban Road Sponge City Design
- Keywords:

- 摘要:
- 基于嘉興市現(xiàn)狀城市道路海綿城市設計方法，根據(jù)道路橫斷面和有無退讓綠地等情況，從指標完成情況、景觀效果、施工難易程度、造價和運行養(yǎng)護等五個方面分析不同設計方法建設效果的優(yōu)缺點并進行綜合評價。在此基礎上,從水質凈化和水量控制兩方面著手，針對現(xiàn)狀城市道路典型橫斷面，最終提出過濾型雨水口、多功能雨水口、分隔帶排水暗渠、生態(tài)樹帶等收集、凈化和滲透雨水的優(yōu)化技術措施，并給出了詳細的設計圖示，可為城市道路海綿城市設計提供參考。
- 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.
