Bioretention pond
The invention relates to the technical field of urban construction, in particular to a biological detention pond which comprises a detention pond body and a stagnant well, a partition wall is arranged in the middle of the stagnant well and divides the stagnant well into a first stagnant water cavity and a second stagnant water cavity, the first stagnant water cavity is communicated with a water outlet of the detention pond body, and the bottom of the second stagnant water cavity is communicated with a municipal pipe network; the lower portion of the partition wall is provided with a first drainage hole communicating with the first stagnant water cavity and the second stagnant water cavity, the middle of the partition wall is provided with a second drainage hole communicating with the first stagnant water cavity and the second stagnant water cavity, and the side, facing the second stagnant water cavity, of the partition wall is connected with a gate body in an up-down sliding and guiding mode. The gate body floats upwards, so that the first drainage hole is blocked by the gate body, the second drainage hole is released by the gate body, the drainage flow is reduced, and the water retention effect is improved; and after the rainwater runoff is reduced, the gate body blocks the second drainage hole and releases the first drainage hole, so that accumulated water in the first retention cavity flows into the second retention cavity through the first drainage hole, and rainwater is prevented from being accumulated in the first retention cavity.
本发明涉及城市建设技术领域，特别是涉及一种生物滞留池，包括滞留池池体和滞水井，滞水井的中部设有隔墙，隔墙将滞水井分隔为第一滞水腔和第二滞水腔，第一滞水腔与滞留池池体的出水口连通，第二滞水腔的底部与市政管网连通；隔墙的下部设有连通第一滞水腔和第二滞水腔的第一泄流孔，隔墙的中部设有连通第一滞水腔和第二滞水腔的第二泄流孔，隔墙朝向第二滞水腔的一侧上下滑动导向连接有闸体；闸体上浮，使得闸体封堵第一泄流孔且闸体释放第二泄流孔，从而降低了泄流流量，提高了滞水效果；雨水径流量降低后，闸体封堵第二泄流孔且闸体释放第一泄流孔，从而使得第一滞留腔内的积水通过第一泄流孔流入第二滞留腔，避免了第一滞留腔内积存雨水。
