River bank vegetation buffer zone and construction method
The invention provides a river bank vegetation buffer zone and a construction method, and the buffer zone comprises an energy dissipation pool which is arranged on the side, close to a river, of an anti-flood wall, the energy dissipation pool is adjacent to a drain outlet in the anti-flood wall, and the energy dissipation pool is used for reducing the flow speed of water flow passing through the drain outlet; a communicating pipeline is arranged between the tree pits of the adjacent trees in the arbor zone and used for balancing the pressure of accumulated water in the tree pits near the drain outlet, and a permeation enhancing layer is arranged in each tree pit; the middle platform is arranged on a slope of a near-water area of a river bank; the interception grass planting ditch is arranged on the middle platform, and lawns are laid in the interception grass planting ditch and used for intercepting pollutants carried in the runoff; reed belts are arranged on the flat ground close to the river area and used for preventing pollutants from entering the river. Through the energy dissipation pool, the flow speed of runoff at the sewage draining exit of the road surface can be effectively reduced, the scouring force of the runoff of the road surface is reduced, and the damage of the runoff on the river bank below the sewage draining exit is reduced; the interception grass planting ditch is arranged on the slope close to the water area so as to intercept pollutants carried in the bottom surface runoff.
本公开提供了一种河岸植被缓冲带及构建方法,缓冲带包括:消能池,设置在防洪墙靠近河流的一侧,消能池与防洪墙上的排污口相邻设置,消能池用于降低通过排污口水流的流速;乔木带,相邻乔木的树坑之间设置有联通管道,用于均衡排污口附近树坑内部积水压力,树坑内设置有增渗层;中间平台,设置在河岸近水区的斜坡上;截留植草沟,设置在中间平台上,截留植草沟内铺设有草坪,用于截留径流中携带的污染物;平地靠近河流区域设置有芦苇带用于阻止污染物入河。通过消能池能够有效地降低路面排污口处径流的流速,降低路面径流的冲刷力,降低地面径流对排污口下方的河岸的破坏;通过在近水区斜坡上设置截留植草沟以截留底面径流中携带的污染物。
