Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the ecological restoration of high and steep slopes directly dumps the covering soil and regreens, and the surface covering soil is easily washed away when it meets rainfall to form a confluence, resulting in poor regreening effect on the slope surface.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 to Figure 3 As shown in the ecological restoration structure of the high and steep slope of the dump site, the upper end of the slope 6 is provided with a step slope top soil retaining 2, and several slope-fixing grass ropes 1 and covering soil 5 are successively laid on the slope surface. Slope Grass Ropes 1 are arranged at intervals, the upper end of Slope Grass Ropes 1 is buried under the soil block 2 at the top of the step, and the 1 section of Slope Grass Ropes on the side slope 6 is woven into a rhombus grid; Rods 3, the slope-fixing anchor rods 3 are arranged at intervals at the intersections between the diamond-shaped grid meshes woven into the slope-fixing grass rope 1, and can fix the slope-fixing grass rope 1 on the side slope 6, and set There are green plants 4 arranged in the meshes of the diamond-shaped grid mesh at the 3 positions ...

Abstract

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.

Description

technical field [0001] The invention relates to an ecological recovery structure for a high and steep slope of a dump site, and belongs to the technical field of slope ecological restoration. Background technique [0002] According to the "Design Specifications for Metallurgical Mine Dump Sites", the types of dumps are mainly hillside type, valley type, and flat terrain. For the hillside and valley types that are stacked along with the mountain topography, the first step is generally affected by the terrain, and the height is not easily controlled by the design. The slope angle of the dump site is mainly affected by the stacked materials, and it is difficult to control it within the angle required by the code. Therefore, the first step of the dump site is likely to form a super high slope. During the construction of the actual dump site, the height of the side slope shall not exceed 30m and the slope shall not exceed 35° according to the code requirements. The shape of the ...
