Ecological restoration structure of high and steep side slope of refuse dump
The invention relates to an ecological restoration structure of a high and steep side slope of a refuse dump, and belongs to the technical field of side slope ecological rehabilitation. A step slope top soil barrier (2) is arranged at the upper end of a slope (6), slope fixing straw ropes (1) and covering soil (5) are laid on the slope surface, the slope fixing straw ropes (1) are arranged at intervals, the upper ends of the slope fixing straw ropes (1) are buried below the step slope top soil barrier (2), the slope fixing straw ropes (1) at the lower middle part are woven into rhombus grid nets, slope fixing anchor rods (3) are further involved, the slope fixing anchor rods (3) are arranged at the mesh intersection points of the rhombic grid nets at intervals, the slope fixing straw ropes(1) are fixed to the slope (6), and green plants (4) are arranged in meshes. According to the ecological restoration structure of the high and steep side slope of the refuse dump, the slope fixing straw ropes (1) are woven into the rhombic grid nets to be fixed to the slope surface, the covering soil (5) is laid on the slope surface, the using amount of the covering soil (5) is reduced, and the problems that the covering soil (5) is directly dumped for rehabilitation in ecological restoration of the high and steep slope, confluence is formed in rainy days, the covering soil (5) on the surfaceis easily washed away, and the slope rehabilitation effect is caused to be poor are solved.
本发明涉及一种排土场高陡边坡的生态恢复结构，属于边坡生态复绿技术领域。边坡(6)的上端设有台阶坡顶土挡(2)，坡面上铺设固坡草绳(1)和覆土(5)，固坡草绳(1)间隔设置，固坡草绳(1)上端埋于台阶坡顶土挡(2)下，中下部固坡草绳(1)编织成菱形格栅网；还包括固坡锚杆(3)，固坡锚杆(3)间隔设置在菱形格栅网网孔交点处，并将固坡草绳(1)固定在边坡(6)上，且网孔内设有绿植(4)。本结构采用固坡草绳(1)编织成菱形格栅网固定于坡面，坡面铺设覆土(5)，减少覆土(5)用量。解决高陡边坡生态恢复直接倾倒覆土(5)复绿，在遇降雨形成汇流造成表面覆土(5)易被冲走，导致坡面复绿效果不佳的问题。
