Description

Technical Field

[0001] This utility model relates to the field of slope protection and management, and in particular to a slope protection structure for mine geological environment management. Background Technology

[0002] Mining, highway and railway construction and other engineering activities in my country have created a large number of artificial slopes. The stability and management of these slopes is an important issue for ecological environmental protection and geological disaster prevention. Currently, slope protection structures such as anchored frame beams and lattice anchoring are commonly used for treating this type of slope. These structures form an integrated protection system by embedding anchors within the slope and connecting them to the reinforced concrete frame or lattice beams on the slope surface. While these methods provide strong anchoring force initially, a significant problem with existing technologies during long-term service is that their fixing effect is difficult to sustain for soft, easily deformable slopes such as soil or fractured rock masses. The specific reasons are as follows: First, under the influence of soil erosion and wet-dry cycles, the bond strength between the soil / rock mass and the anchors gradually weakens, leading to a shortening of the effective anchoring section and a decrease in anchoring force. Secondly, such slopes themselves exhibit continuous, minute creep or relaxation deformation. Traditional rigid anchoring structures cannot adapt to this micro-deformation, resulting in gaps between the anchor rod and the hole wall, and between the frame and the slope surface. This leads to structural loosening and loss of preload, resulting in the failure of the "anchor rod-slope" synergistic effect. Manual maintenance is required, increasing labor costs. Furthermore, once some anchor points fail, the load will be redistributed and exacerbate the burden on the remaining anchor points, triggering a chain reaction that ultimately leads to the failure of the entire protective structure. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a slope protection structure for mine geological environment management in order to solve the technical problems in the prior art.

[0004] To achieve the above objectives, this utility model provides a slope protection structure for mine geological environment management, including a slope body and a protective frame disposed on the slope body. The surface of the protective frame has equidistantly distributed planting holes for planting vegetation. The slope protection structure further includes: Multiple assembly slots are provided on the slope surface; Several positioning sleeves are detachably installed around the protective frame, one end of each positioning sleeve extends into the adjacent assembly slot, and the end of the positioning sleeve located in the assembly slot has an open structure. At least two movable rods are symmetrically arranged radially through the interior of the positioning sleeve, and a positioning plate is fixedly installed at one end of the movable rods extending to the outer wall of the protective frame; A pull rod that moves horizontally through one end of the positioning sleeve has a pressure block fixedly installed at one end of the pull rod, and the surface of one end of the pressure block overlaps with one end of the movable rod. A spring is fitted onto one end of the pull rod, with its two ends respectively abutting between the end face of the pressure block and the inner wall of the positioning sleeve.

[0005] Preferably, the protective frame has several threaded grooves around its perimeter, and the outer surface of the positioning sleeve has an external thread that matches the threaded grooves. The positioning sleeve engages with the threaded grooves through the external thread.

[0006] Preferably, there are 2-4 movable rods, and the surface of the positioning sleeve is provided with multiple mounting holes at equal intervals along the circumferential direction, through which the movable rods movably pass through the positioning sleeve.

[0007] Preferably, a limiting ring is fixedly installed at one end of the movable rod inside the positioning sleeve, and the limiting ring is used to prevent the movable rod from falling out of the positioning sleeve.

[0008] Preferably, the end of the pressure block near the movable rod is a conical surface, and the end of the movable rod near the pressure block is an arc surface, and the arc surface is adapted to the conical surface of the pressure block.

[0009] Preferably, the positioning plate has multiple barbs evenly distributed on one side of its surface facing the assembly groove.

[0010] Preferably, the end of the positioning sleeve away from the positioning plate has a through hole, and the pull rod is inserted through the through hole; A through groove is provided on one side of the inner wall of the perforation, and a connecting block is movably inserted through the through groove and fixedly installed on the surface of the pull rod.

[0011] Preferably, a locking groove is provided on the outer wall of the positioning sleeve away from the positioning plate and on the side of the perforation. The locking groove does not penetrate the end of the positioning sleeve and is adapted to the connecting block.

[0012] The beneficial effects of this utility model are as follows: The slope protection structure for mine geological environment management, employing this utility model, utilizes a mechanical self-locking mechanism composed of a spring-driven tie rod, pressure block, and movable rod to provide a continuous and adjustable radial support force for the positioning sleeve and protective frame. When the slope soil experiences slight relaxation due to wet-dry cycles, soil erosion, or its own creep, the internal spring automatically releases potential energy, pushing the pressure block to continue compressing the movable rod outwards. This ensures the positioning plate remains tightly pressed against the inner wall of the assembly groove, effectively offsetting the loss of pre-tightening force caused by slope deformation, preventing anchor point loosening, and ensuring long-term, stable collaborative performance between the protective frame and the slope. This fundamentally overcomes the shortcomings of traditional rigid anchoring structures that fail due to their inability to adapt to micro-deformations. Through the ingenious cooperation of the tie rod, connecting block, through groove, and locking groove, temporary locking of the movable rod in its retracted state is achieved. During installation, the operator can pre-retract the movable rod, easily insert the positioning sleeve into the assembly groove, and then release the lock after it is in place, allowing the mechanism to automatically unfold and complete the anchoring. This process requires no complex tools or large equipment, resulting in high construction efficiency. Furthermore, the detachable installation of the positioning sleeve 3 allows for direct replacement or repair of the protective frame 2 or the positioning sleeve 3 when local components are damaged or when slope 1 requires maintenance, reducing maintenance costs.

[0018] The first aspect of this utility model proposes a slope protection structure for mine geological environment management, such as... Figure 1-4 As shown, the structure includes a slope 1 and a protective frame 2 installed on the slope 1. The surface of the protective frame 2 has equidistantly distributed planting holes 201 for planting vegetation. The slope protection structure also includes: Multiple assembly slots 101 are excavated on the slope surface of slope 1. First, multiple assembly slots 101 are excavated on the mountain slope 1 at designed intervals. The depth and diameter of the assembly slots 101 are determined according to the geological conditions of the slope, typically with a depth of 300-500 mm and a diameter of 100-200 mm. A protective frame 2 is placed on the surface of slope 1. The protective frame 2 is made of high-strength composite material (such as fiberglass or reinforced concrete), and vegetation planting holes 201 with a diameter of 50-100 mm are evenly opened on its surface for filling with planting soil and sowing plants. Several positioning sleeves 3 are detachably installed around the protective frame 2. One end of the positioning sleeve 3 extends into the adjacent assembly groove 101, and the end of the positioning sleeve 3 located in the assembly groove 101 has an open structure. It should be noted that by pre-making threaded grooves around the protective frame 2, external threads are processed on the outer surface of the positioning sleeve 3, and the positioning sleeve 3 is screwed into the protective frame 2 through thread engagement. The positioning sleeve 3 is made of corrosion-resistant metal material such as stainless steel, and its length is adjusted according to the depth of the assembly groove 101. At least two movable rods 4 are symmetrically arranged radially inside the positioning sleeve 3, and a positioning plate 5 is fixedly installed at one end of the movable rods 4 extending to the outer wall of the protective frame 2; A pull rod 6 moves horizontally through one end of the positioning sleeve 3. A pressure block 7 is fixedly installed at one end of the pull rod 6, and the surface of one end of the pressure block 7 overlaps with one end of the movable rod 4. A spring 8 is fitted onto one end of the pull rod 6, with its two ends abutting against the end face of the pressure block 7 and the inner wall of the positioning sleeve 3, respectively. The spring 8 is a stainless steel compression spring, and its preload is determined by load calculation to ensure that the movable rod 4 continuously presses against the inner wall of the assembly groove 101.

[0019] In this embodiment: the protective frame 2 has several threaded grooves around its perimeter, and the outer surface of the positioning sleeve 3 has external threads that match the threaded grooves. The positioning sleeve 3 engages with the threaded grooves through the external threads. During installation, pulling the pull rod 6 away from the positioning plate 5 compresses the spring 8, causing the connecting block 10 to move out of the positioning sleeve 3. Rotating the pull rod 6 until the connecting block 10 is misaligned with the through groove 9, and then releasing the pull rod 6, one end of the connecting block 10 abuts against the outer wall of the positioning sleeve 3, preventing the spring 8 from returning to its original position. At this time, the movable rod 4 is in the retracted state. One end of the positioning sleeve 3 is inserted into the assembly groove 101 of the slope 1. Then, the pull rod 6 is rotated to align the connecting block 10 with the through groove 9. The spring 8 drives the pull rod 6 to reset. The pressure block 7 squeezes the inner end of the movable rod 4, causing the movable rod 4 to expand radially. The positioning plate 5 presses tightly against the inner wall of the assembly groove 101, thereby effectively offsetting the loss of pre-tightening force caused by the deformation of the slope 1, preventing the anchor point from loosening, ensuring the long-term and stable collaborative working performance between the protective frame 2 and the slope 1, and reducing manual intervention and the workload of personnel.

[0020] In this embodiment: 2-4 movable rods 4 are provided, and multiple assembly holes are equidistantly opened on the surface of the positioning sleeve 3 along the circumferential direction. The movable rods 4 are movably inserted through the positioning sleeve 3 through the assembly holes. 2-4 movable rods 4 are symmetrically inserted radially inside the positioning sleeve 3. The diameter of the movable rods 4 is 10-20mm, and the material is high carbon steel.

[0021] In this embodiment: a limiting ring is fixedly installed at one end of the movable rod 4 inside the positioning sleeve 3. The limiting ring is used to prevent the movable rod 4 from falling out of the positioning sleeve 3. The movable rod 4 is movably installed through the assembly hole on the surface of the positioning sleeve 3. The inner end of the fixed limiting ring has a diameter larger than the assembly hole, and the outer end is welded with a positioning plate 5.

[0022] In this embodiment, the end of the pressure block 7 near the movable rod 4 is a conical surface, and the end of the movable rod 4 near the pressure block 7 is an arc surface, with the arc surface matching the conical surface of the pressure block 7. By matching the arc surface of one end of the movable rod 4 with the conical surface of the pressure block 7, the contact area between the two is reduced, friction is decreased, and it is easier to press the movable rod 4 to move stably.

[0023] In this embodiment, the positioning plate 5 has multiple barbs evenly distributed on the side facing the assembly groove 101. It should be noted that the positioning plate 5 is made of steel plate with a planar dimension of 50mm × 50mm. The plate is bent into an arc shape matching the assembly groove 101, and multiple barbs are welded to the side facing the assembly groove 101 to enhance the mechanical interlocking with the soil and rock of the slope 1.

[0024] In this embodiment: the end of the positioning sleeve 3 away from the positioning plate 5 has a through hole, and the pull rod 6 is inserted through the through hole; A through groove 9 is provided on one side of the perforated inner wall, through which a connecting block 10 moves and is fixedly installed on the surface of the pull rod 6. Before installing the positioning sleeve 3 into the assembly slot 101, the pull rod 6 is pulled away from the positioning plate 5, causing one end of the connecting block 10 inside the positioning sleeve 3 to move out of the positioning sleeve 3. The pull rod 6 is rotated until the connecting block 10 is misaligned with the through groove 9. After releasing the pull rod 6, one end of the connecting block 10 abuts against the outer wall of one end of the positioning sleeve 3, restricting the elastic return of the spring 8, thereby preventing the pressure block 7 from squeezing the movable rod 4, so that the positioning sleeve 3 can be inserted into the assembly slot 101. This process does not require complicated tools or large equipment, has high construction efficiency, and the detachable installation of the positioning sleeve 3 makes it easy to replace or repair the protective frame 2 or the positioning sleeve 3 when local components are damaged or when slope 1 needs maintenance.

[0025] In this embodiment, a locking groove 11 is provided on the outer wall of the positioning sleeve 3 away from the positioning plate 5, on the side with the through hole. The locking groove 11 does not penetrate the end of the positioning sleeve 3, and the locking groove 11 is adapted to the connecting block 10. After the connecting block 10 is rotated to the position corresponding to the locking groove 11, under the elastic reset action of the spring 8, the pull rod 6 drives one end of the connecting block 10 to be inserted into the locking groove 11, so as to improve the stability of locking the position of the pull rod 6 and facilitate the installation of the positioning sleeve 3. After the positioning sleeve 3 is installed in place, the pull rod 6 is rotated in the opposite direction to make the connecting block 10 disengage from the locking groove 11. Under the elastic reset action of the spring 8, the movable rod 4 expands radially, and the positioning plate 5 presses tightly against the inner wall of the assembly groove 101 to complete the assembly.
