[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the embodiments.

[0028] Specific embodiments of the mine repair device provided by the utility model:

[0029] See also Figure 1-5 The mine repair device includes several layers of protective nets 1 and several anchors 2 for fixing the protective nets 1; the protective nets 1 can be made of wire mesh or fiber mesh. In this embodiment, wire mesh is preferably used.

[0030] There are gaps between each layer of the protection net 1 to form multiple layers of corresponding protection nets 1. Compared with the single-layer protection net 1, the multi-layer protection net 1 can significantly improve the soil fixing and anti-scouring effect. During the vegetation growth process, the multi-layer protection net 1 does not affect the growth of the vegetation root system, and can be intertwined with the root system to form a whole after the vegetation root system grows. It has excellent soil fixing and anti-scouring effect and will not block rainwater penetration.

[0031] The anchors 2 are evenly arranged on the multi-layer protection net 1, pass through the protection net 1, and are connected to each layer of the protection net 1. Each layer of the protection net 1 is connected to the anchors 2 at equal intervals to ensure that each layer of the protection net 1 has a uniform gap, thereby restricting each layer of the covering soil and reducing the covering soil from being eroded by rainwater.

[0032] In this embodiment, the anchor 2 includes a sleeve 21 and an anchor rod 22. The sleeve 21 is connected to the protective net 1 and is sleeved on the outer side of the upper part of the anchor rod 22. The anchor rod 22 includes a limiting column 221 and a plug rod 222. The upper part of the plug rod 222 is provided with an internal threaded hole 2221; the vertical cross-section of the limiting column 221 is T-shaped, and the lower part of the limiting column 221 is provided with an external threaded section 2211 threadedly matched with the internal threaded hole 2221; the limiting column 221 passes through the sleeve 21, and the upper end of the limiting column 221 is attached to the upper side of the sleeve 21.

[0033] In this embodiment, the upper end of the limiting column 221 is disc-shaped, the main body of the insertion rod 222 is cylindrical, the inner diameter of the sleeve 21 is smaller than the outer diameter of the insertion rod 222, and the inner diameter of the sleeve 21 is smaller than the outer diameter of the upper end of the limiting column 221. In some other embodiments, the upper end of the limiting column 221 can be set to a hexagonal prism instead of a disc-shaped structure.

[0034] After the limiting column 221 is threadedly connected with the insertion rod 222, the upper end of the limiting column 221 can press the sleeve 21 on the upper side of the insertion rod 222 to support and fix the sleeve 21. After the limiting column 221 is separated from the insertion rod 222, the anchor rod 22 can be separated from the sleeve 21; Figure 5 As shown, the multi-layer protection net 1 and the sleeve 21 can be rolled up to facilitate the storage and transportation of the protection net 1; during the mine repair process, the anchor rod 22 is installed to fix the multi-layer protection net 1.

[0035] Using this device to repair the mine process:

[0036] like Figure 5 As shown, a multi-layer protective net 1 with a sleeve 21 is laid on the surface of a mine slope;

[0037] Then, the anchor rods 22 are installed one by one, and the position of the sleeve 21 is determined first, so that the sleeve 21 is away from and tightens the protection net 1, so that the protection net 1 forms a separated multi-layer state with relatively uniform gaps;

[0038] like Figure 4 As shown, the limiting column 221 and the insertion rod 222 are placed on the upper and lower sides of the sleeve 21, the limiting column 221 passes through the sleeve 21, and the limiting column 221 is rotated to make the external thread section 2211 at the lower end of the limiting column 221 screwed into the internal thread hole 2221 at the upper part of the insertion rod 222; after completion, the state of the anchor 2 is as follows Figure 3 As shown;

[0039] The upper end of the limit column 221 is hammered to insert the insertion rod 222 into the surface layer of the mine slope; in this embodiment, the lower end of the anchor rod 22, that is, the lower end of the insertion rod 222, is provided with an inverted cone 2222 to facilitate the insertion and fixing of the insertion rod 222; the anchor rod 22, that is, the outer side of the insertion rod 222, is provided with barbs 2223, and the barbs 2223 can reduce the loosening of the anchor rod 22 and enhance stability; in this embodiment, the barbs 2223 are arranged in two layers, and each layer has a plurality of barbs, which are evenly distributed around the circumference;

[0040] While fixing the anchor rods 22 one by one, the fixed multi-layer protection net 1 is covered with soil, and vegetation is planted, and regular maintenance is required in the later stage.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
