Description

Technical Field

[0001] The utility model belongs to the technical field of mine ecological restoration, and particularly relates to a mountain reinforcement device for mine ecological restoration. Background Technique

[0002] Mine ecological restoration refers to, after the end of mine exploitation activities, through a series of engineering and biological measures, restoring the ecological environment damaged by mining activities, making it return to the natural state, and further achieving the purpose of sustainable development. Among them, the mountain reinforcement device plays an important role in this process. It can not only stabilize the mountain body, prevent geological disasters, but also create favorable conditions for subsequent ecological restoration. Due to the mountain reinforcement devices in related technologies, during the actual application process, they fail to maintain sufficient close combination with the mountain body, resulting in insufficient combination strength. This situation is likely to cause the loosening of the reinforcement device during stress or long-term use, thereby affecting the overall stability and safety. For example, during the installation process of anchor rods, if the drilling angle, depth, and filling material are not properly selected, the anchor rods may not be firmly embedded in the mountain body. Similarly, when using slope protection nets, if the close contact with the ground surface cannot be ensured, or the lap part is not properly treated, these devices may also have the risk of displacement and shedding when dealing with natural environmental changes (such as rainfall and earthquakes). Therefore, how to improve the combination strength of these reinforcement devices with the mountain body is an important technical problem that needs to be solved urgently. Summary of the Invention

[0003] In view of this, the utility model aims to solve at least one of the related technical problems to a certain extent.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] A mountain reinforcement device for mine ecological restoration includes a geogrid, two fixed guard strips, two slope protection nets, two grid anchoring structures, and four slope net fixing structures;

[0006] One of the grid anchoring structures is correspondingly arranged at each of the left and right ends of the geogrid, and the grid anchoring structure is used to press the geogrid;

[0007] One of the fixed guard strips is correspondingly arranged at each of the front and rear ends of the geogrid, and the fixed guard strip is used to press and fix the geogrid;

[0008] The two slope protection nets are symmetrically arranged on the two fixed guard strips left and right, and each slope protection net structure is connected through two of the slope net fixing structures;

[0009] The two slope net fixing structures are symmetrically arranged on the left and right sides of the slope protection net. The slope net fixing structures are used to compress and fix the slope protection net. An elastic anchoring structure is correspondingly arranged at the front and rear ends of each slope net fixing structure.

[0010] Furthermore, the slope net fixing structure includes a fixed pressure plate and a thickened pad, the thickened pad is arranged on the lower end surface of the fixed pressure plate, and the elastic anchoring structure passes through the fixed pressure plate and the thickened pad.

[0011] Furthermore, the elastic anchoring structure includes an anchor rod, a pressure rod, a pressure block, a first compression spring and a second compression spring. The bottom of the pressure rod is connected to the anchor rod, and the top of the pressure rod is connected to the pressure block. The first compression spring and the second compression spring are both arranged on the pressure rod. The pressure rod passes through the fixed pressure plate, the thickened pad and the fixed guard strip in sequence. The first compression spring is arranged between the anchor rod and the fixed guard strip, and the second compression spring is arranged between the fixed guard strip and the thickened pad.

[0012] Furthermore, a first bent edge is provided at the top of the fixed guard strip, the opening of the first bent edge faces outward, and strip holes are provided at the left and right ends of the first bent edge, and the pressure rod passes through the strip holes.

[0013] Furthermore, the grille anchoring structure includes a protective plate and a plurality of locking devices, a second bent edge is provided at the bottom of the protective plate, an opening of the second bent edge faces inward, and a plurality of the locking devices are evenly arranged on the second bent edge.

[0014] Furthermore, the locking device is a U-shaped anchor.

[0015] Furthermore, the number of the locking devices is 4.

[0016] Compared with the prior art, the mountain reinforcement device for mine ecological restoration described in the utility model has the following advantages:

[0017] 1. The first compression spring and the second compression spring can provide continuous compression force, so that the geogrid, slope protection net, etc. are closely combined with the mountain and improve the fixing effect. The elastic characteristics of the spring enable it to adapt to the slight deformation and displacement of the mountain and prevent loosening and falling off. The compression spring can effectively absorb and disperse the vibration caused by earthquakes, wind, etc., reduce the impact on the anchoring structure, and protect the safety of the overall structure. When subjected to sudden external force, the spring can play a buffering role, reduce the instantaneous impact force on the anchor rod and the fixed guard strip, and extend the service life of the device. By adjusting the preload of the spring, the optimal pressure can be applied according to different environmental conditions to ensure the long-term stability of the device. The design of the spring structure is relatively simple, easy to operate and install during construction, and does not require complex equipment and processes.

[0018] 2. Through the combination of the protection plate and multiple U-shaped anchor bolts, the geogrid can be firmly fixed to the ground to prevent it from sliding or falling off. The design of the protection plate increases the contact area with the geogrid, disperses the pressure, and further improves the fixing effect. The protection plate can be flexibly adjusted in position according to the terrain, adapt to different geological conditions, and achieve better fitting. Multiple locking devices are evenly arranged on the protection plate to provide multi-point anchoring, which can effectively cope with the problem of uneven stress distribution caused by terrain changes or external forces (such as wind and rainfall). The installation of the U-shaped anchor bolts is relatively simple. Just drill holes at the appropriate positions and insert the anchor bolts to complete the fixation, which reduces the construction difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
