- 摘要:
- 吴忠市地处我国西北半干旱地区，降雨较少但极端降雨多发，合流制排水系统占比较高，合流制溢流污染及道路积水问题不容忽视。针对道路雨水径流总量控制与污染物削减问题，系统解析了吴忠市既有道路海绵化改造工程特征，提出将综合调蓄-下渗能力比参数（R）作为快速确定溢流设施设置的依据，明确低影响导流-自然调蓄（自然存蓄）、设施强化-协同调蓄（前端海绵设施+后端自然存蓄）、常规渗滞-安全溢流（常规海绵设施建设+超标溢流模式），以及分车带调蓄4类改造模式。以吴忠市世纪大道改造项目为实证案例，阐释了“模式组合优化-径流分级调控-景观生态融合”技术路径。该研究成果可为西北半干旱地区城市道路雨洪管理提供理论指导与技术参考，对缓解城市内涝及合流制溢流污染控制具有重要的实践价值。
- Abstract:
- Wuzhong City is located in the semi-arid region of Northwest China, where rainfall is scarce but extreme rainfalls occur frequently. With a high proportion of combined sewer systems, the pollution from combined sewer overflows (CSOs) and road waterlogging pose significant challenges. This study addresses the issues of total volume control and pollution reduction of stormwater runoff from roads. It systematically analyzes the characteristics of existing sponge city transformation projects on roads in Wuzhong and innovatively proposes a comprehensive parameter—the storage-infiltration capacity ratio (R)—to enable rapid determination of overflow facility design. Four transformation modes are defined: low-impact diversion and natural storage (natural retention); facility enhancement and synergistic storage (front-end sponge facilities + back-end natural retention); conventional infiltration-retention and safe overflow (conventional sponge facility construction + excess overflow mode); and median strip storage. Using the Shiji Avenue transformation project as a case study, the technical pathway of “mode combination optimization, graded runoff regulation, and landscape-ecological integration” is elaborated. The research outcomes provide theoretical guidance and technical references for stormwater management on urban roads in semi-arid northwestern regions, offering practical value for mitigating urban waterlogging and controlling CSOs pollution.
