Description

Technical Field

[0001] The present invention belongs to the technical field of slope protection structures, and specifically refers to a slope protection structure for preventing collapse in mine restoration. Background Art

[0002] Slope protection refers to preventing slope instability, landslides or collapses through engineering measures to ensure the safety and stability of slopes. 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, anchor bolts, etc., providing physical support; drainage systems: setting drainage ditches, drain pipes, etc., to prevent landslides caused by water pressure; reinforcement measures: such as soil nails, anchor cables, etc., to enhance slope stability. Slope protection can prevent problems such as landslides, soil erosion and traffic interruption. After mining, the mountain structure changes. Without adding protection equipment, major safety accidents such as mountain collapses will occur.

[0003] Currently, the most commonly used method for slope protection is to construct lattice girders on the slope and plant plants between the lattice girders to enhance the stability of the slope. However, this method requires on-site pouring in the slope area. Since most slopes are on both sides of the road, road closures are required during the manufacture of lattice girders and it takes a long time. If prefabricated lattice girders are used and buried deep into the slope, they need to be customized according to the length and width of the slope, and transportation is relatively difficult. If the protection structure can be assembled and installed on the slope, the costs in terms of transportation, installation, road closure, etc. can be reduced. Summary of the Invention

[0004] In view of the above situation, to solve the problems of long time consumption, high cost and poor soil and water retention effect in current slope protection, the present invention provides a slope protection structure for preventing collapse in mine restoration, designs a slope protection structure that can be assembled and spliced, with a simple and stable structure, fast installation, and can be assembled according to the area and shape of the slope. The outstanding advantages of this application document are that it can fully divert rainwater, reduce soil erosion and avoid mountain collapses.

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

[0006] Furthermore, the cover plate fixing structure includes a central cover plate, an edge cover plate, and fixed anchor rods. The central cover plate is installed on the slope, the edge cover plate is fixedly connected to the central cover plate, the fixed anchor rods are snap-fitted into the jacks on the edge cover plate. The thickness of the central cover plate is greater than that of the edge cover plate, and the connection surface between the central cover plate and the edge cover plate is set as an inclined surface, which is conducive to the rainwater to converge and drain towards the edge cover plate direction.

[0007] Furthermore, the rainwater erosion prevention planting structure includes plant planting holes, annular card slots, and rainwater direct impact prevention plates. The plant planting holes are fixedly arranged on the edge cover plate, the annular card slots are fixedly arranged on the edge cover plate, the plant planting holes and the annular card slots are concentrically arranged. The rainwater direct impact prevention plates are snap-fitted and slidably installed on the annular card slots. When two groups of edge cover plates are combined side by side, the two groups of rainwater direct impact prevention plates can be snap-fitted together.

[0008] Preferably, both the central cover plate and the edge cover plate are designed as equilateral triangle structures. When the slope slides, when the external force generated by the slope acts on the edge cover plate of the triangle, the force will be evenly transmitted to the whole structure through the sides and corners, avoiding stress concentration, thereby enhancing stability. At the same time, the central cover plate and the edge cover plate cover the slope, and only the plant planting holes are reserved as the plant planting area, reducing the probability of soil erosion caused by rainwater scouring along the slope. While guiding the rainwater along the edge cover plate, the rainwater direct impact prevention plates reduce the volume of soil scoured and lost in the plant planting holes.

[0009] Furthermore, the combined soil pressing device includes an insertion and extrusion fixing device and a limit and sealing structure. The insertion and extrusion fixing device is snap-fitted on the slope cover plate, and the limit and sealing structure is snap-fitted on the insertion and extrusion fixing device; the insertion and extrusion fixing device includes a triangular pyramid insertion block, a triangular pyramid card slot, edge ridges, a threaded expansion tube, and a spindle bolt. The triangular pyramid card slot is fixedly arranged at the center of the central cover plate, the triangular pyramid insertion block is snap-fitted into the triangular pyramid card slot, the edge ridges are fixedly installed on both sides of the side edges of the triangular pyramid insertion block. There are through grooves on the side edges of the triangular pyramid insertion block, which is conducive to the triangular pyramid insertion block to expand outward and squeeze the surrounding soil to make the soil more compact. The threaded expansion tube is fixedly installed in the triangular pyramid insertion block, and the spindle bolt is threadedly connected to the threaded expansion tube. When the spindle 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 flipping clamping plate, a flipping plate slot, a first limit elastic block, and a first elastic block slot. The sealing port is fixedly arranged on the triangular pyramid insertion block. The sealing plate is snap-fitted on the sealing port. The pressing column is fixedly installed on the sealing plate. The flipping plate slot is fixedly arranged on the triangular pyramid insertion block. The flipping clamping plate is rotatably snap-fitted in the flipping plate slot. The flipping clamping plate and the flipping plate slot are connected by a torsion spring. The pressing column is in contact with the flipping clamping plate. The first elastic block slot is connected to the flipping plate slot. The first limit elastic block is snap-fitted in the first elastic block slot, and the first limit elastic block and the first elastic block slot are connected by a spring. When the pressing column presses one end of the flipping clamping plate, the flipping clamping plate rotates, the first limit elastic block pops out from the first elastic block slot, and limits the flipping clamping plate, and the flipping clamping plate restricts the movement direction of the sealing plate to prevent the sealing plate from detaching from the triangular pyramid insertion block. The sealing plate is snap-fitted and slidably installed on the spindle-shaped bolt.

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

[0012] Furthermore, the second edge slot clamping block is set as a right triangle, which is beneficial to prevent the connecting pipe sleeve from detaching from the splicing combination column when the second edge slot clamping block is snap-fitted in the triangular edge slot.

[0013] Preferably, the splicing combination column is set as a semi-cylindrical structure, and two groups of the splicing combination columns can be combined into a complete cylindrical structure.

[0014] The beneficial effects of a slope protection structure for mine restoration and anti-collapse provided by this solution are as follows:

[0015] (1) Design an edge cover plate in the shape of a triangle, making the slope protection structure stable, capable of withstanding the extrusion of the surrounding mountains on the slope, avoiding damage to the slope. At the same time, the central cover plate and the edge cover plate with different heights play a role in guiding rainwater when the central cover plate and the edge cover plate are washed by rainwater, reducing the soil erosion rate in the central area of the central cover plate.

[0016] (2) The engagement and contact between the sealing plate and the flipping clamping plate realize the contact sealing function when the sealing plate is installed at the sealing opening, isolating the soil inside the central cover plate from external rainwater, avoiding soil erosion during rainfall. At the same time, the mutual cooperation between the connecting pipe sleeve and the splicing combination column enables the interlocking between multiple groups of edge cover plates, ensuring the stability between the edge cover plates.

[0037] The second edge groove clamping block 29 is set as a right triangle.

[0038] The splicing combined column 26 is set as a semi-cylindrical structure.

[0039] During specific use, lay the central cover plate 6 and the edge cover plate 7 on the slope. Insert the fixed anchor bolt 8 into the slope through the jacking hole on the fixed point of the edge cover plate 7 to fix the central cover plate 6 and the edge cover plate 7 relative to the slope. Insert the triangular pyramid insertion block 14 into the slope from the triangular pyramid card slot 15 in the middle of the central cover plate 6. During the installation process, the triangular pyramid insertion block 14 can be deeply buried into the slope by tapping with a small hammer. In order to make the triangular pyramid insertion block 14 fully squeeze the loose soil in the slope, insert the spindle bolt 18 along the thread into the threaded expansion pipe 17. The triangular pyramid insertion block 14 is extruded outward by the spindle bolt 18. While changing the shape of the triangular pyramid insertion block 14, the soil around the triangular pyramid insertion block 14 is extruded to make the surrounding soil more stable.

The triangular central cover plate 6 and the edge cover plate 7 have a stable structure and can resist the deformation of the slope soil. When the planted plants are those with more water absorption, the rainwater straight impact prevention plate 11 can be flipped, and the inner wall of the rainwater straight impact prevention plate 11 faces the rainwater flowing down along the edge cover plate 7. When the slope structure is loose and it is necessary to avoid the slope being washed away by rainwater to the greatest extent, install the sealing plate 19 on the spindle bolt 18 and press it into the sealing port 20 during installation. The pressing column 21 presses one side of the flipping clamping plate 22. The bottom of the flipping clamping plate 22 is pressed, and the middle position of the flipping clamping plate 22 is clamped and rotated on the flipping plate card slot 23. The balance of the flipping clamping plate 22 is broken and it rotates, changing the angle of the flipping clamping plate 22. The top end of the flipping clamping plate 22 rotates and presses, and the limit elastic block one 24 pops out from the elastic block card slot one 25. At this time, the flipping clamping plate 22 presses on the top wall of the sealing plate 19, and the bottom of the flipping clamping plate 22 is squeezed and limited by the limit elastic block one 24 to ensure the stability of the sealing plate 19 in the sealing port 20 and prevent rainwater from entering the sealing port 20 and taking away the slope soil.
