Embodiment 1

[0022] Basic as attached figure 1 Shown: an open-pit mine steep slope ecological restoration structure, including the first planting bag 2 at the top and bottom of the slope 1, the first planting bag 2 at the top of the slope 1 is set one meter away from the top of the slope 1, and two A whole piece of steel wire mesh 3 is laid on the slope 1 between the first planting bags 2. The steel wire mesh 3 is made of flexible galvanized steel wire mesh or plastic coated steel wire mesh, and the steel wire mesh 3 is made of high-quality low-carbon steel wire. The mesh surface is flat and the structure is firm. Even if the wire mesh 3 is partially cut or partially subjected to pressure, it will not loosen. The mesh shape of the wire mesh 3 can be diamond, oval, quadrilateral, Hexagonal and other shapes.

[0023] There are also vines 4 planted on the surface of the slope. The vines 4 can be vines such as creeper, linseed vine, ivy vine, trumpet creeper, honeysuckle, pueraria lobata, polygon...

Embodiment 2

[0033] As attached figure 2 As shown, the difference between this embodiment and Embodiment 1 is only that it is aimed at the slope 1 with many steps, large height differences, and large water catchment surface. The repair structure in this embodiment only adds a drainage ditch 10. The intercepting drainage ditch 10 is arranged on the cultivated soil on the right side of the retaining wall 7, and drainage can be facilitated by the intercepting drainage ditch 10.

Embodiment 3

[0035] The difference between this embodiment and the first embodiment is that the retaining wall 7 adopts a stone cage. The diameter of the stones filled in the stone cage is between 20cm-40cm. Compared with the planting bag, the stone cage can enhance the stability of the retaining wall 7 , And the view of the gabion will be better than that of the plant bag, suitable for both sides of the road and sidewalk. For stone cages, there are usually many stones left on the side slope. If the retaining wall 7 adopts the stone cage, it can be used directly, which reduces the manufacturing cost of the retaining wall 7.

Abstract

The invention discloses an open pit mine steep slope ecological restoration structure and a restoration method, and particularly relates to the technical field of ecological restoration and land reclamation. The open pit mine steep slope ecological restoration structure comprises first vegetation bags located on the top and the bottom of a slope. A steel wire net and vine plants are laid at the position, between the two first vegetation bags, of the slope. Anchors are arranged between the steel wire net and the slope. Nutrient soil is laid below the vegetation bag at the bottom of the slope. The vine plants are arranged on the nutrient soil. A second vegetation bag is arranged on one side of the nutrient soil, retaining walls are arranged on one side of the second vegetation bag at intervals, the positions between the retaining walls and the second vegetation bag are filled with planting soil, and vegetation is arranged on the planting soil. By the adoption of the technical scheme, theproblem that an existing mine slope cannot retain water and nutrients in soil, so that the vegetation dies off is solved, and the open pit mine steep slope ecological restoration structure and the restoration method can be used for large-gradient slope restoration.

Description

Technical field [0001] The invention relates to the technical field of ecological restoration and land reclamation, in particular to an open-pit mine steep slope ecological restoration structure and restoration method. Background technique [0002] At this stage, the ecological restoration method for slopes with slopes greater than 55° in open-pit mines is mainly to cover the foot of the slope and plant vines on the slope. If the water source is good, the pre-embedded sprinkler pipe is used for maintenance. If the water source is not good, The artificial sprinkler is used for maintenance. The defects in the above restoration methods are: 1. The soil is easily lost due to the erosion of natural wind and rain and surface runoff; 2. After the soil and nutrients are lost, the roots of the plants are exposed, the growth of the plants stagnates or even wither, resulting in waste of investment; 3. When the mine terrain is complex, the terrain is high, there are many platforms, and the ...
