Description

Technical Field

[0001] This invention mainly relates to the field of mine ecological restoration equipment technology, specifically a mountain reinforcement device for mine ecological restoration. Background Technology

[0002] The rock walls left after mining are steep and lack soil, making it impossible for plants to grow and hindering natural ecological restoration. Furthermore, the prolonged exposure of the rock strata to the outside environment easily leads to weathering, causing the rocks to loosen and detach. Therefore, it is necessary to restore the ecological environment of the mine.

[0003] Currently, there are three main types of artificial restoration techniques: 1. Hydroseeding with netting to plant turf; 2. Planting in planting beds; and 3. Planting in planting bags or blocks. Hydroseeding with netting involves driving net stakes into the rock face, fixing plastic or steel mesh of a specific aperture to the entire rock face through these stakes, leaving a gap between the rock face and the mesh. This gap is then filled with fine, even soil, and finally, a mud slurry mixed with grass seed is sprayed over the mesh. After a period of maintenance, the entire rock face is covered with turf.

[0004] The existing hydroseeding technology with netting suffers from soil shallowness and large gaps between the rock layer and the netting. After two to three years of rain erosion, the soil between the rock wall and the netting is severely lost, and the rock wall and netting are easily exposed, making it difficult for plants to grow on the rock wall for a long time. Long-term maintenance and repair are required, and the ecological restoration effect is difficult to achieve as expected. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mountain reinforcement device for mine ecological restoration, achieved through the following technical solution:

[0006] A mountain reinforcement device for mine ecological restoration includes a rectangular frame. A hollow column is fixedly installed at the center of the rectangular frame via a bracket. A first through hole is opened at the center of the bottom surface of the column, and a second through hole is opened at the center of the top surface of the column. A short pipe is integrally fixedly installed in the first through hole. A threaded sleeve is fixedly installed inside the column. A screw rod is installed in the threaded sleeve with internal thread. The screw rod vertically penetrates the short pipe. A baffle is fixedly installed at the lower end of the screw rod. An internal hexagonal groove is provided on the top surface of the screw rod. A hanging mesh is fixedly installed inside the rectangular frame.

[0007] Furthermore, the outer periphery of the short tube is provided with several evenly distributed first through grooves.

[0008] Furthermore, a third through hole is provided in the center of the internal hexagonal groove. The third through hole passes through the screw and the baffle in sequence. A conveying pipe is movably inserted into the third through hole. The upper end of the conveying pipe is integrally fixedly installed with a pipe joint.

[0009] Furthermore, a piston is fixedly installed on the outside of the conveying pipe, and the outer periphery of the piston slides in contact with the inner wall of the third through hole.

[0010] Furthermore, several vertical plates are fixedly installed on the top surface of the rectangular frame, and ropes are wound between the vertical plates.

[0011] Furthermore, the rope is made of hemp rope.

[0012] Furthermore, interconnected strip grooves are provided around the rectangular frame, and several second through grooves communicating with the strip grooves are respectively provided at the edges of the top surface of the rectangular frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When in use, this device fixes a rectangular frame to the rock stratum and places a hanging net inside the rectangular frame. The rectangular frame can hinder the movement of the soil and slow down the flow of water within the rectangular frame, thereby greatly reducing the impact of rainwater erosion on the soil and improving the soil retention effect on the rock stratum, thus providing good soil conditions for plant growth.

[0020] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0021] Example: A mountain reinforcement device for mine ecological restoration

[0022] like Figure 1 As shown in Figure 4, a mountain reinforcement device for mine ecological restoration has the following specific structure:

[0023] A rectangular frame 1 has a hollow column 2 fixedly mounted at its center via a bracket. A first through hole 3 is opened at the center of the bottom surface of the column 2, and a second through hole 19 is opened at the center of the top surface of the column 2. A short pipe 4 is integrally fixedly mounted in the first through hole 3. A threaded sleeve 5 is fixedly mounted in the column 2. A screw 6 is threadedly mounted in the threaded sleeve 5. The screw 6 vertically penetrates the short pipe 4. A baffle 7 is fixedly mounted at the lower end of the screw 6. The top surface of the baffle 7 contacts the bottom surface of the short pipe 4. The top surface of the screw 6 has an internal hexagonal groove 8. A hanging mesh 9 is fixedly mounted inside the rectangular frame 1.

[0024] The short tube 4 has several evenly distributed first through slots 10 on its outer periphery, which are arranged in a ring array on the outer periphery of the short tube 4. This structural design can reduce the strength of the short tube 4. When the screw 6 drives the baffle 7 to press the bottom of the short tube 4 upward, the short tube 4 can deform and protrude outward under the pressure of the baffle 7, so that the short tube 4 can be fixed by mutual compression with the inner wall of the mounting hole, thereby improving the fixing effect of the device.

[0025] A third through hole 11 is provided in the center of the internal hexagonal groove 8. The third through hole 11 passes through the screw 6 and the baffle 7 in sequence. A delivery pipe 12 is movably inserted into the third through hole 11. The upper end of the delivery pipe 12 is integrally fixed with a pipe connector 13. When in use, the device is connected to an external concrete or adhesive pipeline through the pipe connector 13. Concrete or adhesive is injected into the rock stratum installation hole through the delivery pipe 12 to fill the internal gaps. After the concrete or adhesive solidifies, it can wrap around the short pipe 4, screw 6 and baffle 7, further increasing the firmness of the device installation and preventing it from falling off during use.

[0026] A piston 14 is fixedly installed on the outside of the delivery pipe 12, and the outer periphery of the piston 14 slides in contact with the inner wall of the third through hole 11. The piston 14 can fill the gap between the delivery pipe 12 and the third through hole 11, preventing concrete or adhesive from overflowing through the third through hole 11 during the injection of concrete or adhesive into the installation hole.

[0027] Several vertical plates 15 are fixedly installed on the top surface of the rectangular frame 1, and ropes 16 are wound between the vertical plates 15. The ropes 16 and the vertical plates 15 can impede water flow and retain soil, reduce the scouring effect of water flow, and prevent soil erosion. When mud is sprayed on the top of the rectangular frame 1, the ropes 16 can be buried in the mud. At this time, the ropes 16 are directly inserted into the soil, which greatly increases the contact area between the device and the soil, and can prevent the soil from being washed away by water flow.

[0028] The rope 16 is made of hemp rope. Hemp rope can be degraded during use, which can greatly reduce environmental pollution. When the plants mixed in the mud take root and sprout, the plant roots can directly replace the rope 16 to retain water and soil. At this time, the degraded components of the rope 16 can be used as nutrients for the plants. The degraded rope 16 also facilitates the subsequent transplanting of plants and will not hinder the transplanting process.

[0029] The rectangular frame 1 has interconnected strip grooves 17 around its perimeter, and several second through grooves 18 communicating with the strip grooves 17 are respectively opened at the edges of the top surface of the rectangular frame 1. When installed, the rectangular frames 1 are arranged in a vertical, horizontal, and vertical sequence. The opposing strip grooves 17 on adjacent rectangular frames 1 combine to form water channels. Rainwater can flow downwards through the second through grooves 18 into the corresponding strip grooves 17, thereby reducing the water flow on the surface of the rectangular frame 1, reducing the erosion of the soil covering the surface of the rectangular frame 1 by rainwater, improving the soil retention effect of the device, ensuring the normal growth of plants, and contributing to the improvement of the ecological environment.

[0030] How to use:

[0031] S1: Drill an installation hole in the corresponding part of the rock stratum using a drilling machine. The diameter of the installation hole is larger than the outer diameter of the short pipe 4.

[0032] S2: Insert the short tube 4, screw 6, and baffle 7 at the bottom of the rectangular frame 1 into the mounting hole together;

[0033] S3: Remove the delivery pipe 12 from the short pipe 4, insert the external hex wrench into the internal hexagonal groove 8, and rotate the external hex wrench to drive the screw 6 to rotate. When the screw 6 rotates, it moves upward along the threaded sleeve 5 that it is in contact with. At this time, the screw 6 drives the baffle 7 connected to it to move synchronously. The baffle 7 applies upward pressure to the bottom of the short pipe 4. Under the squeezing action of the baffle 7, the short pipe 4 deforms and protrudes outward. At this time, the outer side of the short pipe 4 is squeezed against the inner wall of the mounting hole, thereby fixing the short pipe 4 in the mounting hole, thus realizing the fixation of the rectangular frame 1 to the rock stratum.

[0034] S4: After the rectangular frame 1 is fixed, the mud and grass seeds are mixed, and the mud mixed with grass seeds is sprayed onto the rectangular frame 1 and the hanging net 9 by a centrifugal pump.

[0035] S5: After the plant takes root and sprouts, its root system penetrates the soil, which can improve the soil's retention effect and thus improve the ecological environment.

[0036] When in use, this device can receive mud through the rectangular frame 1, slowing down the rate of mud loss, and improve the soil retention effect through the hanging net 9 inside the rectangular frame 1. As the plants grow, the plant roots can continuously interweave between the soil and the hanging net 9, and the plant roots will firmly grasp the soil, which can prevent soil erosion and improve the soil, thereby improving the ecological environment of the mine and preventing rock weathering from causing rock loosening.
