Refuse dump road slope greening structure

Abstract

The invention discloses a refuse dump road slope greening structure. The refuse dump road slope greening structure comprises a road, a slope and biological fences, wherein a platform is arranged between the road and the slope; the biological fences are arranged on the surfaces of the platform and the slope; each biological fence comprises a plane part laid on the surface of the platform and an inclined plane part laid on the surface of the slope; the plane part and the inclined plane part are connected through a bent weft; and the bent weft is laid at the joint of the platform and the slope. According to the refuse dump road slope greening structure, the biological fences are laid on the platform and the slope for greening; and meanwhile, the bent weft is laid at the slope corner where theplatform and the slope are connected, so that rainwater is effectively prevented from being washed from the slope corner, and the problems that a slope greening structure and a slope surface are washed by rainwater and separated to cause water and soil loss, and plant root systems are separated from slope surface soil to cause uneven greening are solved.

Description

technical field [0001] The invention relates to the field of ecological restoration of dump sites, in particular to a green-covered structure for road slopes in dump sites. Background technique [0002] Dump site, also known as waste rock site, refers to the place where mining waste is discharged intensively. Wastes from dump sites generally include humus topsoil, weathered rock and soil, hard rock and mixed rock and soil, and sometimes may include off-surface ore and lean ore that may be recovered. The dump site platform is a stepped road that spirals to connect the bottom and the top of the slope. There is a buffer platform on the edge of the road, and people on the roadside go up and down the dump site along the platform. At present, the greening of the slope of the dump site is mainly carried out on the slope of the dump site, and the buffer platform at the edge of the road is only compacted, and no greening treatment is performed on it. At this time, there are the fol...

AI Technical Summary

Problems solved by technology

At this time, there are the following problems: First, the slope reforestation technology of the dump site generally only lays biological fences on the slope, and plants are exposed on the platform. Affected by rainfall, many channels will still be formed under the biological fences. As time goes by, there are more and more channels under the biological fence, which will cause serious plant degradation in the long run

The second is that at the angle where the upper side slope and the platform meet, the rainwater washes between the green structure of the side slope and the side slope of the dump site, forming a ditch. At the same time, the green structure is separated from the slope surface, and the roots of the plants planted on the green structure are separated. The soil on the slope surface makes the part of the slope near the slope corner smooth and grass-free, and the greening effect of the entire platform is not good; third, when encountering heavy rain or heavy rain, it is easy to separate the green structure of the slope from the slope surface, and the runoff rushes to the slope. And engulfed in sediment and rushed to the platform below, it is easy to erode the platform below
