[0027] The mine repair device provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0028] The present application embodiment discloses a mine repair device. Figure 1 As shown, the mine repair device includes a metal mesh 1, a base layer 2 and a seed layer 3; wherein the metal mesh 1 is installed on the slope 4 of the mine, with a gap between the metal mesh 1 and the slope 4; the base layer 2 covers the slope 4 and the metal mesh 1; and the seed layer 3 covers the base layer 2.

[0029] By using the mine repair device in the technical solution, a metal mesh 1 is installed on the slope 4, and the metal mesh 1 is spaced apart from the surface of the slope 4 of the mine, so that the base layer 2 can be coated on the metal mesh 1, and the base layer 2 can be more stably attached to the slope 4 through the metal mesh 1. Therefore, after the seed layer 3 is covered on the base layer 2, soil erosion can be reduced, and the stability of the structure of the exposed rock slope 4 is effectively improved, so that the seeds in the seed layer 3 can grow stably, and the survival rate of green plants is improved. After a period of growth, the roots of the vegetation system can more easily penetrate into the soil, effectively improving the effect of the management of the exposed rock slope 4.

[0030] In some embodiments of the present invention, Figure 1 As shown, the mine repairing device further includes a plurality of main anchoring rods 5 and a plurality of secondary anchoring rods 6 .

[0031] Among them, a plurality of main anchor rods 5 are evenly distributed on the slope 4 , one end of the main anchor rod 5 is fixed on the slope 4 , and the other end extends from the surface of the slope 4 .

[0032] A plurality of secondary anchor rods 6 are evenly distributed on the slope 4 , one end of the secondary anchor rod 6 is fixed on the slope 4 , and the other end thereof extends out from the surface of the slope 4 .

[0033] The metal mesh 1 is fixed to the portions of the primary anchor rods 5 and the secondary anchor rods 6 extending to the surface of the slope 4 .

[0034] The metal mesh 1 can be fixed on the slope 4 by the main anchor rods 5 and the secondary anchor rods 6, and a gap is formed between the metal mesh 1 and the surface of the slope 4, so that the base layer 2 can be filled in the gap and the side of the metal mesh 1 away from the slope 4, thereby ensuring the overall structural stability of the base layer 2 and the slope 4.

[0035] It can be understood that the multiple secondary anchoring rods 6 are distributed between the multiple main anchoring rods 5 , the main anchoring rods 5 play a major fixing role on the metal mesh 1 , and the secondary anchoring rods 6 play an auxiliary fixing role on the metal mesh 1 .

[0036] In some embodiments of the present invention, a plurality of main anchor rods 5 and a plurality of secondary anchor rods 6 are arranged on the slope 4 in a plum blossom shape.

[0037] In this embodiment, the plurality of main anchoring rods 5 and the plurality of secondary anchoring rods 6 are arranged in a plum blossom shape or an irregular shape and are evenly distributed and should not be arranged in a straight line.

[0038] It should be noted that the plum blossom-shaped arrangement is a five-point distribution. Specifically, the four vertices and the center point of the rectangle are taken, and the main anchor rods 5 or the secondary anchor rods 6 are arranged at these points respectively, so that the main anchor rods 5 and the secondary anchor rods 6 are arranged in a plum blossom shape. This can improve the overall structural stability of the main anchor rods 5 and the secondary anchor rods 6 and the slope 4, thereby improving the fixing stability of the metal mesh 1, the base layer 2 and the seed layer 3 and the slope 4.

[0039] Furthermore, the overall spacing between the main anchor rods 5 is 1.8-2.2m*1.8-2.2m, and the overall spacing between the secondary anchor rods 6 is 0.8-1.2m*0.8-1.2m.

[0040] In some embodiments of the present invention, Figure 1 As shown, the length of the main anchor rod 5 is 50-60 cm, the length of the secondary anchor rod 6 is 30-40 cm, and both the main anchor rod 5 and the secondary anchor rod 6 are exposed on the surface of the slope 4 by 3 to 4 cm.

[0041] In this embodiment, most of the length of the main anchor rod 5 or the secondary anchor rod 6 is buried in the slope 4 by drilling holes in the slope 4. On the one hand, the longer main anchor rod 5 can ensure the overall fixation and stability of the metal mesh 1. On the other hand, the shorter secondary anchor rod 6 increases the anchoring points of the metal mesh 1, which not only makes the metal mesh 1 more evenly stressed and more stably fixed, but also reduces the damage to the slope 4 and the cost of drilling holes in the slope 4.

[0042] Furthermore, the main anchor rod 5 and the secondary anchor rod 6 are both threaded steel bars, which can be well fixed together in the hole of the slope 4 through concrete and have a high connection strength.

[0043] The main anchor rod 5 and the secondary anchor rod 6 are preferably made of φ14 threaded steel bar, and φ12 threaded steel bar, φ13 threaded steel bar, φ15 threaded steel bar, φ16 threaded steel bar, etc. may also be used.

[0044] It should be understood that the main anchor rods 5 and the secondary anchor rods 6 can be reasonably selected according to different slopes 4 .

[0045] In some embodiments of the present invention, the metal mesh 1 is tied to the main anchor rod 5 and the secondary anchor rod 6 at a distance of 2 to 3 cm from the surface of the slope 4 .

[0046] It can be understood that the metal mesh 1 is 2 to 3 cm away from the surface of the slope 4, that is, 2 to 3 cm of the overall thickness of the base layer 2 is located between the metal mesh 1 and the surface of the slope 4, thereby ensuring that the base layer 2 has a sufficiently strong connection with the metal mesh 1 and the slope 4.

[0047] In some embodiments of the present invention, Figure 1 As shown, the thickness of the base layer 2 is 5-7 cm, and the thickness of the seed layer 3 is 4-5 cm.

[0048] Specifically, in this embodiment, the base layer 2 is composed of planting soil, peat, sawdust, straw fiber, calcium magnesium phosphate, compound fertilizer, granulating agent, etc. in proportion. The seed layer 3 is composed of planting soil, peat, straw fiber, compound fertilizer, calcium magnesium phosphate, wood fiber, granulating agent, seeds, etc. in proportion.

[0049] The base layer 2 and the seed layer 3 with materials such as granulating agents have extremely strong adhesive force, and can be firmly adsorbed on the slope 4 with the metal mesh 1, and can resist rain erosion and wind erosion and prevent soil and water loss.

[0050] Furthermore, the material of the base layer 2 and the material of the seed layer 3 are respectively laid on the slope 4 by spraying.

[0051] Furthermore, the total thickness of the base layer 2 and the seed layer 3 is not less than 10 cm, and the sowing amount per square meter is not less than 10 g.

[0052] In some embodiments of the present invention, Figure 1 As shown, the metal mesh 1 extends from the side slope 4 to the top of the slope 7 of the mine.

[0053] It should be understood that at the top of the slope 7, the metal mesh 1 is also fixed by the main anchor rods 5 and the secondary anchor rods 6, and the base layer 2 and the seed layer 3 are covered on the metal mesh 1 at the top of the slope 7, thereby forming a certain pulling effect on the metal mesh 1, the base layer 2 and the seed layer 3 of the slope 4, further improving the stability of the overall structure of the mine repair device.

[0054] In some embodiments of the present invention, the mesh size of the metal mesh 1 is 5-7 cm*5-7 cm.

[0055] Furthermore, the metal mesh 1 is a galvanized mesh, and the wire diameter of the galvanized mesh is not less than φ2.0 mm, so that the metal mesh 1 has sufficient strength and corrosion resistance.

[0056] Furthermore, the mesh sheets of the galvanized mesh are overlapped by 10 cm, thereby improving the continuity and stability of the entire metal mesh 1 .

[0057] In some embodiments of the present invention, Figure 1 As shown, the mine restoration device also includes a coconut fiber blanket 8, which covers the seed layer 3. Covering with the coconut fiber blanket 8 can effectively reduce the erosion of vegetation by heavy rainfall in the rainy season, and can also reduce water evaporation in the dry season, thereby protecting the plant system.

[0058] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
