Stagnation-purification-drainage combined urban road rainwater drainage device and method
The invention relates to the technical field of rainwater drainage, in particular to a stagnant-clean-drainage combined urban road rainwater drainage device and method, and the device comprises a permeable pavement, a rainwater drainage box culvert, a concave greenbelt, a kerb opening, a bioretention zone and an overflow well. The sidewalk adopts a water-permeable pavement, a rainwater drainage box culvert is arranged below the water-permeable pavement, the section of the rainwater drainage box culvert is square, and holes are uniformly formed in a top plate of the rainwater drainage box culvert. And a green belt between the sidewalk and the non-motorized vehicle lane adopts a concave green land. Initial rainwater of a non-motorized vehicle lane and a motorized vehicle lane is discharged into a bioretention zone in a non-motorized vehicle lane isolation zone through a kerb opening and flows into an overflow port through a perforated pipe laid at the bottom of the bioretention zone after being retained and purified, rainwater runoff exceeding the retention capacity of the bioretention zone is firstly discharged into the overflow port, and the overflow port is connected with an overflow well through a pipeline. Rainwater runoff exceeding the drainage capacity of the overflow port is drained into the overflow well, and the overflow well is connected with the rainwater drainage box culvert. According to the urban road rainwater drainage device and method, rainwater runoff pollution can be effectively controlled, and urban road waterlogging can be relieved.
本发明涉及雨水排水技术领域，尤其涉及一种滞‑净‑排组合式城市道路雨水排水装置及方法，包括透水铺装、雨水排水箱涵、下凹式绿地、路缘石开口、生物滞留带、溢流井。人行道采用透水铺装，透水铺装下方设雨水排水箱涵，雨水排水箱涵截面为方形，其顶板上均匀开孔。人行道与非机动车道之间绿化带采用下凹式绿地。非机动车道、机动车道初期雨水通过路缘石开口排入机非隔离带中的生物滞留带，经滞留净化后通过生物滞留带底部铺设的穿孔管流入溢流口，超过生物滞留带滞蓄能力的雨水径流首先排入溢流口，溢流口通过管道与溢流井连接，超过溢流口排水能力的雨水径流排入溢流井，溢流井与雨水排水箱涵连接。该城市道路雨水排水装置及方法可有效控制雨水径流污染，缓解城市道路积水内涝。
