Description

Technical Field

[0001] The invention belongs to the technical field of slope protection structures, and specifically refers to a slope protection structure for mine repair and anti-collapse. Background Art

[0002] Slope protection refers to the use of engineering measures to prevent slope instability, landslides or collapses, ensuring the safety and stability of the slope. Common protection methods include: vegetation protection: fixing the soil by planting plants to reduce erosion; engineering structure protection: such as retaining walls, slope protection walls, anchors, etc., to provide physical support; drainage system: setting up drainage ditches, drainage pipes, etc. to prevent water pressure from causing landslides; reinforcement measures: such as soil nails, anchor cables, etc., to enhance slope stability. Slope protection can prevent landslides, soil erosion, and traffic interruptions. After mining, the mountain structure changes. If protective equipment is not added, it will cause major safety accidents such as mountain collapse.

[0003] Currently, the most commonly used method for slope protection is to construct lattice beams on the slope and plant plants between the lattice beams to enhance the stability of the slope. However, this method requires on-site pouring in the slope area. Since the slopes are mostly on both sides of the road, the road needs to be closed when manufacturing the lattice beams, which is time-consuming. If prefabricated lattice beams are used and then buried deep in the slope, they need to be customized according to the length and width of the slope, and transportation is more difficult. If the protective structure can be combined and spliced ​​and installed on the slope, the costs of transportation, installation, and road closure can be reduced. Summary of the invention

[0004] In view of the above situation, in order to solve the problems of long time consumption, high cost and poor soil and water conservation in the current slope protection, the present invention provides a slope protection structure for preventing collapse in mine restoration, and designs a slope protection structure that can be combined and spliced. It has a simple and stable structure and is quick to install. It can also be combined and assembled according to the area and shape of the slope. It can fully divert rainwater, reduce soil and water loss, and avoid mountain collapse, which is an outstanding advantage of this application document.

[0005] The technical solution adopted by the present invention is as follows: A slope protection structure for mine restoration and anti-collapse provided by the present invention includes a slope covering plate, a combined soil pressing device, and a splicing fixing device. The slope covering plate is installed on the slope, the combined soil pressing device is snap-fitted and installed on the slope covering plate, and the splicing fixing device is installed on the slope covering plate; the slope covering plate includes a covering plate fixing structure and a rainwater erosion prevention planting structure, the covering plate fixing structure is installed on the slope, and the rainwater erosion prevention planting structure is snap-fitted and installed on the covering plate fixing structure.

[0006] Furthermore, the cover plate fixing structure includes a central cover plate, an edge cover plate, and a fixing anchor rod. The central cover plate is installed on the slope, the edge cover plate is fixedly connected to the central cover plate, and the fixing anchor rod is snap-fitted into the socket on the edge cover plate. The thickness of the central cover plate is greater than the thickness of the edge cover plate, and the connecting surface between the central cover plate and the edge cover plate is set as an inclined surface, which is conducive to the collection and diversion of rainwater in the direction of the edge cover plate.

[0007] Furthermore, the rainwater erosion prevention planting structure includes a plant planting hole, an annular groove and a rainwater prevention straight-impulse plate. The plant planting hole is fixedly set on the edge cover plate, the annular groove is fixedly set on the edge cover plate, the plant planting hole and the annular groove are concentrically set, and the rainwater prevention straight-impulse plate is snap-fitted and slidably installed on the annular groove. When two sets of edge cover plates are combined side by side, the two sets of rainwater prevention straight-impulse plates can be snap-fitted and installed together.

[0008] Preferably, the central cover plate and the edge cover plates are designed to be an equilateral triangle structure. When the central cover plate and the edge cover plates of the triangular structure encounter a slope landslide, when the external force generated by the slope acts on the triangular edge cover plates, the force will be evenly transmitted to the entire structure through the edges and corners, avoiding stress concentration, thereby enhancing stability. At the same time, the central cover plate and the edge cover plates cover the slope, leaving only the plant planting holes as the plant planting area, reducing the probability of rainwater scouring along the slope and causing soil erosion. While diverting rainwater along the edge cover plates, the rainwater direct impact prevention plate reduces the volume of soil in the plant planting holes that is washed away.

[0009] Furthermore, the combined soil pressing device includes an inserting and squeezing fixing device and a limiting sealing structure, the inserting and squeezing fixing device is snap-fitted and installed on the slope covering plate, and the limiting sealing structure is snap-fitted and installed on the inserting and squeezing fixing device; the inserting and squeezing fixing device includes a triangular pyramid insertion block, a triangular pyramid slot, an edge, a threaded expansion tube, and a shuttle bolt, the triangular pyramid slot is fixedly arranged at the center of the central cover plate, the triangular pyramid insertion block is snap-fitted and installed in the triangular pyramid slot, the edge is fixedly installed on both sides of the side edges of the triangular pyramid insertion block, and a through groove is provided on the side edges of the triangular pyramid insertion block, which is conducive to the triangular pyramid insertion block to open and squeeze the surrounding soil when expanding outward to make the soil more compact, the threaded expansion tube is fixedly installed in the triangular pyramid insertion block, and the shuttle bolt is threadably connected to the threaded expansion tube. When the shuttle bolt is inserted into the triangular pyramid insertion block along the thread of the threaded expansion tube, the bottom of the triangular pyramid insertion block expands outward.

[0010] Furthermore, the limit sealing structure includes a sealing plate, a sealing port, a pressing column, a flip splint, a flip plate slot, a limit spring block 1, and a spring block slot 1, wherein the sealing port is fixedly arranged on the triangular pyramid insertion block, the sealing plate is clamped and installed on the sealing port, the pressing column is fixedly arranged on the sealing plate, the flip plate slot is fixedly arranged on the triangular pyramid insertion block, the flip splint is clamped and rotatably installed in the flip plate slot, the flip splint is connected to the flip plate slot by a torsion spring, the pressing column is in contact with the flip splint and is connected to the flip plate slot, the spring block slot 1 is connected to the flip plate slot, the limit spring block 1 is clamped and installed in the spring block slot 1, and the limit spring block 1 and the spring block slot 1 are connected by a spring, when the pressing column presses one end of the flip splint, the flip splint rotates, the limit spring block 1 pops out from the spring block slot 1, and limits the flip splint, the flip splint limits the moving direction of the sealing plate to prevent the sealing plate from detaching from the triangular pyramid insertion block, and the sealing plate is clamped and slidably installed on the shuttle bolt.

[0011] Furthermore, the splicing and fixing device includes a splicing combination column, a triangular side groove, a connecting pipe sleeve, a side groove block 2, and a block hidden groove 2. The splicing combination column is fixedly installed on the side wall of the edge cover plate, the triangular side groove is fixedly set on the side wall of the splicing combination column, the connecting pipe sleeve is snap-fitted and installed on the splicing combination column, the block hidden groove 2 is fixedly set on the inner wall of the connecting pipe sleeve, the side groove block 2 is snap-fitted and slidably set in the block hidden groove 2, and the side groove block 2 and the block hidden groove 2 are connected by a spring.

[0012] Furthermore, the side groove clamping block 2 is configured as a right-angled triangle, which is beneficial for preventing the connecting pipe sleeve from being separated from the spliced ​​combination column when the side groove clamping block 2 is engaged in the triangular side groove.

[0013] Preferably, the spliced ​​composite column is configured as a half-cylindrical structure, and two groups of the spliced ​​composite columns can be combined into a complete cylindrical structure.

[0014] This solution provides a slope protection structure for mine repair and anti-collapse, and its beneficial effects are as follows: (1) The triangular-shaped edge cover makes the slope protection structure stable and can resist the squeezing of the surrounding mountains on the slope to avoid slope damage. At the same time, the central cover and edge cover with different heights can divert rainwater when it washes the central cover and edge cover, thereby reducing the loss rate of soil in the central area of ​​the central cover; (2) The sealing plate and the flip clamp are in contact with each other to realize the contact sealing function when the sealing plate is installed on the sealing port, isolating the soil in the central cover plate from the external rainwater to avoid soil erosion during rainfall. At the same time, the connection pipe sleeve and the spliced ​​combination column cooperate with each other to make multiple sets of edge cover plates interlocked, ensuring the stability between the edge cover plates.
