Underslope rainwater runoff collecting, distributing and reducing system
The invention relates to an under-slope rainwater runoff collecting, distributing and reducing system which comprises a gravel groove, and the gravel groove is arranged along a slope toe and filled with gravel; the top of the first rain collecting ditch is sealed by a cover plate, and the first rain collecting ditch is communicated with the gravel groove through the ditch wall, close to one side of the gravel groove, of the first rain collecting ditch; the top of the catchment ditch is covered with a rainwater grate, and a plurality of flow guide openings are formed in the bottom of the ditch wall of the other side, away from the initial rainwater collecting ditch, of the catchment ditch at intervals; a seepage and drainage pipe and a water collecting pipe are buried in the permeable pavement, a water outlet of the seepage and drainage pipe is communicated with the water collecting pipe, and the water collecting pipe is communicated with a municipal rainwater pipe network. According to the rainwater runoff separation device, solid substances such as silt in rainwater runoff can be effectively separated, initial rainwater and middle-later rainwater can be separated, the separated silt is easy to clean, and rainwater runoff reduction and pollution control can be achieved at the same time. And the problem of potential aggravation of blockage of a permeable system possibly caused by rainwater runoff can be effectively prevented when the device is applied to a sponge city.
本发明涉及一种坡下雨水径流收集、分流、减量系统，包括碎石槽，碎石槽沿边坡坡脚设置，碎石槽内填充有碎石；初雨收集沟，初雨收集沟的顶部以盖板密封，初雨收集沟通过其靠近碎石槽一侧的沟壁与碎石槽连通；汇水沟，汇水沟的顶部盖有雨水篦子，汇水沟远离初雨收集沟的另一侧沟壁底部间隔开设有多个导流口；以及透水路面，透水路面中埋设有渗排管及集水管，渗排管的出水口与集水管连通，集水管与市政雨水管网连通。本发明能实现雨水径流中泥沙等固体物质的有效分离以及初期雨水和中后期雨水的分流，且分离出的泥沙易于清理，能同时实现雨水径流量的削减和污染的控制。运用在海绵城市中可有效预防雨水径流可能带来的潜在的加剧透水系统堵塞的问题。
