[0002] Abandoned mine exploitation can form near-vertical high and steep slope in partial area, and this type of slope is easy to cause water and soil loss, landslide and other ecological and geological disasters due to lack of vegetation coverage, and also threatens the surrounding environment and resident safety. The mine repair work is committed to restoring the damaged land due to mining activities, but these areas usually lack sufficient soil coverage, rocks are exposed and the terrain is complex, so the traditional vegetation reconstruction method is difficult to implement, resulting in a big problem of vertical green. The traditional repair technology attempts to improve by spraying seed and fiber material mixture to rock surface, installing green plant wall and other methods, but the plant needs to overcome the condition of almost no soil to ensure seed germination, and there is the problem of low seed germination rate and survival rate. SUMMARY

[0003] In view of the low germination rate and difficult vegetation survival of direct spraying seed on vertical high and steep slope during abandoned mine repair, the utility model provides a vertical green structure for mine repair, which is convenient for plant germination and survival.

[0004] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0005] A vertical green structure for mine repair comprises a plurality of anchor rod assemblies and a plurality of frames, wherein each frame is connected with the anchor rod assembly, and a connecting assembly is further arranged between every two frames; a waterproof layer and a soil fixation assembly are arranged in the frame, wherein the waterproof layer is connected with the frame; the soil fixation assembly is connected with the frame, so as to divide the frame into a plurality of grooves; and a planting layer is filled in the groove.

[0006] Further, the soil fixation assembly comprises a plate A and a plate B matched with each other, and the two ends of the plate A and the plate B are respectively provided with a concave clamping block matched with the thickness of the frame, wherein the top of the plate A and the bottom of the plate B are provided with a strip-shaped gap at the corresponding positions, and the plate A and the plate B are matched and clamped through the strip-shaped gap. During construction, the plate A is first fixed to the frame through the concave clamping block, then the plate B is clamped and matched by matching the strip-shaped gap in the middle and the fixed frame at both ends, so that a plurality of grooves are formed in the frame, then the planting layer suitable for plant growth is filled in the groove, the modular installation mode of the plate A and the plate B simplifies the construction process, reduces the cost and improves the stability of the overall structure, and the frame is divided into a plurality of grooves, which can better consolidate the planting layer.

[0007] Further, the plate A and plate B are both wave plates. The wave plates used by the plate A and plate B can enhance the friction between the soil retaining assembly and the soil, prevent the soil from sliding, thereby enhancing the soil retention capacity, reducing the risk of soil erosion, and facilitating vegetation growth.

[0008] Further, the connecting assembly is an inverted U-shaped block, and the width of the gap in the middle of the U-shaped block corresponds to the thickness of the two frames. During the mine repair process, the frames are fixed at the predetermined position, and then the gap in the middle of the U-shaped block is clamped between the two frames to achieve stable connection between the frames. This improvement simplifies the installation process, allows the overall construction of the frame grid to be completed quickly without additional fasteners, enhances the stability and integrity of the entire vertical green covering structure, effectively prevents the stability of the planting layer filled in the frame from being affected by external environment, and is conducive to the growth and survival of vegetation. At the same time, the connection method also greatly improves the construction efficiency and reduces the labor cost.

[0009] Further, the U-shaped block is further provided with a drill rod for limiting and fixing at the bottom.

In use, the anchor rod part of the anchor rod assembly is inserted into the mine soil, so that the limiting plate abuts against the soil to provide stable support and prevent the anchor rod from being inserted too much or too little. Then the hanging rings at the two ends of the connecting rod are respectively inserted into the threaded rod of the anchor rod assembly, and then the threaded sleeves are installed in the threaded rod to limit the connecting rod. The threaded sleeves ensure that each mounting rod is firmly connected to the anchor rod assembly to form a stable frame structure. The precise cooperation between the threaded rod and the threaded sleeve enhances the stability and load-bearing capacity of the entire structure, and this design can adjust the height and levelness of the frame according to actual needs, improving the construction flexibility and adaptability.

[0011] Further, the waterproof layer is provided with a plurality of connecting rings matched with the threaded sleeves along the edge, and the connecting rings are limited by the threaded sleeves. The connecting rings of the waterproof layer are aligned with the threaded sleeves on the frame during installation and are fixed by the threaded sleeves. This not only simplifies the installation steps of the waterproof layer and improves the construction efficiency, but also enhances the stability between the frame and the waterproof layer, effectively prevents water loss and penetration, and helps to maintain the humidity and nutrients of the planting layer, promoting vegetation growth.

[0012] Further, the planting layer comprises soil and seeds mixed uniformly together. The soil is mixed with the seeds uniformly to form the planting layer before use, wherein the seeds can be ivy, ophiopogon japonicus and the like. The vegetation not only has a good greening effect, but also can fix soil through root systems and enhance the stability of the entire green structure.

[0013] Further, the hanging net is covered on the surface of the frame and is connected with the frame or the anchor rod assembly through a cable tie or a wire. The hanging net is laid on the outer side of the frame first, and then is fixed firmly on the frame or the anchor rod assembly through the cable tie or the wire, so that the hanging net is tightly attached to the frame and is stable. The hanging net enhances the protection of the planting layer, prevents soil loss caused by soil falling, and provides additional support to help the climbing plants such as ivy grow and expand better, thereby enhancing the stability and greening effect of the slope.
