Ecological retention grass ditch
The invention discloses an ecological retention grass ditch which comprises a ditch body, the ditch body extends in the road direction, the cross section of the ditch body is trapezoidal or rectangular, two clay water-resisting layers are arranged at the bottom of the ditch body, bricked waterproof retaining walls are laid on the two side walls of the ditch body, and a gravel layer and a soil replacing and filling layer are sequentially laid on the clay water-resisting layers. The gravel layer comprises an upper gravel layer and a lower gravel layer, the soil replacement and filling layer is made of evenly-mixed sandy soil, a blind pipe is buried in the lower gravel layer, an overflow catch basin and an overflow gutter inlet are arranged in the groove, and the blind pipe enters the overflow catch basin and the overflow gutter inlet nearby. The elevation of the overflow gutter inlet is lower than that of the road surfaces on the two sides and higher than that of the surface of the soil replacement and filling layer. The system has remarkable advantages in the aspects of waterproof performance, soil humidity control, rainwater drainage, environmental protection and the like, and has very good practicability and environmental friendliness.
本发明公开一种生态滞留草沟，包括有沟槽，沟槽延道路方向延伸，沟槽的横截面为梯形或矩形，沟槽的底部为黏土隔水层，黏土隔水层有两层，沟槽的两个侧壁铺设有砖砌的防水挡墙，黏土隔水层上方依次铺设砾石层与换填土层，砾石层包括有上砾石层和下砾石层，换填土层采用拌合均匀的砂土，下砾石层内埋设有盲管，沟槽内布置有溢流雨水井与溢流雨水口，盲管就近进入溢流雨水井与溢流雨水口，溢流雨水口的标高低于两侧的道路路面高度且高于换填土层表面的高度。本发明在防水性能、土壤湿度控制、雨水排放和环境保护等方面都有显著的优势，具有很好的实用性和环保性。
