Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, specifically to a self-anchored recyclable prestressed slope reinforcement device. Background Technology

[0002] Slope reinforcement is an important aspect of geotechnical engineering, widely used in highway and railway cutting slopes, reservoir banks in water conservancy projects, mining areas, and building foundation pits to prevent geological disasters such as landslides, collapses, and rockfalls. Traditional slope reinforcement methods mainly include retaining walls, anti-slide piles, anchor bolts (cables), grid beams, and shotcrete with mesh. Among these, flexible protective netting systems (such as active and passive protective netting) are widely used in preventing shallow landslides and rockfalls due to their advantages of fast construction speed, strong adaptability, and good adhesion to the slope surface. In the construction of flexible protective netting, rolled steel wire rope netting or geogrid is usually first laid out along the slope surface, and then the edges and center of the protective netting are fixed to the slope using anchor bolts or anchor nails to form a flexible protective layer covering the slope surface. Anchor bolts provide anchoring force through drilling, insertion of the bolt body, and grouting. This construction method is maturely applied in conventional slope protection projects.

[0003] However, the anchoring force of traditional anchor bolts relies on the bond strength between the grout and the borehole wall. The construction process is cumbersome, requiring multiple steps such as drilling, cleaning, grouting, and curing. This results in a long construction period and is subject to weather conditions, making rapid anchoring difficult. More importantly, traditional anchoring structures are mostly for single use; the anchor bolts and grout cannot be recycled, leading to significant material waste. Furthermore, in complex terrain or ecologically sensitive areas, leftover anchor bolts and grout may hinder subsequent land use and vegetation restoration. Summary of the Invention

[0014] This invention provides a self-anchored, recyclable prestressed slope reinforcement device. It has the following beneficial effects: I. This self-anchored recyclable prestressed slope reinforcement device, by setting an anchoring mechanism, anchors the entire device into the slope rock and soil, providing pull-out bearing capacity, and achieves the application and release of anchoring force through the tensioning of the expansion mechanism. At the same time, under the action of the locking mechanism, it can penetrate deep into the soil to achieve the effect of increasing anchoring force.

[0015] II. This self-anchored recyclable prestressed slope reinforcement device, through the setting of an expansion mechanism, uses the power generated by the locking mechanism after the anchoring pipe is driven into place to adaptively embed itself into the rock and soil, ultimately forming a strong anchoring force.

[0016] Third, this self-anchored recyclable prestressed slope reinforcement device, through the setting of a cloth laying mechanism, releases the protective net from the storage cylinder and lays it on the slope surface during use, thereby achieving flexible reinforcement and protection of the slope and preventing the slope from loosening and causing landslides.

[0017] IV. This self-anchored recyclable prestressed slope reinforcement device, by setting a locking mechanism, locks the rotating cylinder after the protective net is laid in place, preventing the protective net from accidentally retracting under tension and maintaining the tension of the protective net.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] like Figures 1-4 As shown, the present invention provides a technical solution: a self-anchored recyclable prestressed slope reinforcement device, including a support frame 1, with a storage cylinder 2 fixed to the inner wall of the support frame 1. By setting the support frame 1 as the installation skeleton of the entire reinforcement device, in use, the support frame 1 is placed at the top of the slope to stabilize the entire device. The device also includes: A fabric-laying mechanism 3 is used to reinforce the slope with fabric. The fabric-laying mechanism 3 is located inside the cavity of the receiving cylinder 2. The fabric-laying mechanism 3 includes a first rolling bearing 31, which is fixed to the inner wall of the support frame 1. A rotating cylinder 32 is fixed to the inner ring of the first rolling bearing 31. The rotating cylinder 32 is rotatably connected to the inner cavity of the receiving cylinder 2, and a protective net 33 is fitted onto the outer surface of the rotating cylinder 32. By providing the receiving cylinder 2, its inner cavity is used to accommodate and store the protective net 33, providing winding space when the protective net 33 is retracted, thus protecting the protective net 33 from external damage. By providing the fabric-laying mechanism 3, the protective net 33 is released from the receiving cylinder 2 and laid on the slope surface during use, achieving flexible reinforcement and protection of the slope, thereby preventing the slope from loosening and causing landslides. By setting the first rolling bearing 31, the rotating cylinder 32 is supported to rotate smoothly within the receiving cylinder 2, converting the sliding friction between the rotating cylinder 32 and the receiving cylinder 2 into rolling friction, thus reducing the operational resistance when the protective net 33 is retracted or extended. The rotating cylinder 32, serving as the winding carrier for the protective net 33, can rotate within the receiving cylinder 2, enabling the release and retraction of the protective net 33. The protective net 33, fitted over the outer surface of the rotating cylinder 32, covers the slope surface after unfolding, providing flexible reinforcement and protection. A discharge port 7 extends through the outer surface of the storage cylinder 2. This discharge port 7 is angled relative to the lower surfaces of the support frame 1 and the support plate 5. The end of the protective net 33 protrudes through the discharge port 7 from the outer surface of the storage cylinder 2. A fixing plate 34 is fixed to one end of the protective net 33 on the outer surface of the storage cylinder 2. By providing the discharge port 7, a passage is provided for the protective net 33 to pass through. Its inclination angle allows the protective net 33 to be laid towards the slope surface in a predetermined direction, ensuring the accuracy of the laying direction.

[0023] A handle 35 is fixed to the upper surface of the fixing plate 34, and an anchor plate 36, which is curved and blade-shaped, is fixed to the lower surface of the fixing plate 34. The handle 35 facilitates the operator's grip to pull the fixing plate 34 and the protective net 33, making the installation of the protective net 33 more convenient and labor-saving. The anchor plate 36, being curved and blade-shaped, is inserted into the slope soil after the protective net 33 is laid in place, anchoring the end of the protective net 33 to the slope surface and preventing slippage when tensioned. The anchor plate 36 is curved after being inserted into the soil, with the curved bottom facing the receiving cylinder 2, preventing the protective net 33 from rebounding and curling, thus preventing loosening of the protective net 33 in the event of a landslide.

[0024] like Figures 5-10 As shown, this self-anchored recyclable prestressed slope reinforcement device also includes an anchoring mechanism 6. A support plate 5 is fixed to the surface of the anchoring mechanism 6, and the support plate 5 is fixed to the outer surface of the support frame 1. The anchoring mechanism 6 includes an anchoring tube 68, which is fixed to the outer surface of the support plate 5. An expansion mechanism 69 is provided in the inner cavity of the anchoring tube 68. The expansion mechanism 69 includes a second rolling bearing 691, which is fixed to the inner wall of the anchoring tube 68. An internally threaded tube 692 is fixed to the inner ring of the second rolling bearing 691, and a gear 693 is fixed to the top of the outer surface of the internally threaded tube 692. By setting the anchoring mechanism 6, the entire device is anchored in the slope soil and rock mass, providing pull-out bearing capacity. The anchoring force is applied and released by the tensioning of the expansion mechanism 69. At the same time, under the action of the locking mechanism 4, it can penetrate deep into the soil to increase the anchoring force. Anchor tube 68, with a hollow tube shape and a pointed bottom, is designed to facilitate easy insertion into the slope soil and rock during anchoring, providing a solid anchoring foundation for the entire device. Expansion mechanism 69, after anchor tube 68 is driven into place, uses the power generated by locking mechanism 4 to adaptively embed itself into the soil and rock, ultimately forming a strong anchoring force. Second rolling bearing 691 supports the smooth rotation of internal threaded tube 692 within anchor tube 68, reducing rotational friction resistance. Gear 693, fixed to the top of the outer surface of internal threaded tube 692, cooperates with locking mechanism 4 to convert the linear motion generated by locking mechanism 4 into the rotational motion of internal threaded tube 692, driving expansion mechanism 69.

[0025] The self-anchored recyclable prestressed slope reinforcement device also includes a locking mechanism 4, which is used to lock the fabric laying mechanism 3. The locking mechanism 4 is set on the outer surface of the support frame 1. By setting the locking mechanism 4, the rotating cylinder 32 is locked after the protective net 33 is laid in place, preventing the protective net 33 from accidentally retracting under tension, maintaining the tension of the protective net 33, and at the same time, the power generated by the fabric laying mechanism 3 during the laying process can be used to drive the anchoring mechanism 6, preventing the entire device from loosening during the laying process. The locking mechanism 4 includes a limiting cylinder 41, which is fixed to the end of the support frame 1 away from the receiving cylinder 2. A sliding column 42 is slidably connected to the inner cavity of the limiting cylinder 41. A pull rod 43 is fixed to the end of the sliding column 42 away from the receiving cylinder 2. A first spring 44 is sleeved on the outer surface of the sliding column 42, and the end of the first spring 44 is fixed to the inner wall of the limiting cylinder 41. By setting a limiting cylinder 41 as a sliding guide cylinder for the sliding column 42, the sliding column 42 is ensured to move stably in a predetermined direction. The sliding column 42 can slide stably within the limiting cylinder 41, driving the locking block 45 to move, thus locking and unlocking the rotating cylinder 32. The pull rod 43 facilitates the operator to pull the sliding column 42, releasing the locking block 45 from the positioning frame 46, facilitating the release and retraction of the protective net 33. A first spring 44, sleeved on the outer surface of the sliding column 42, provides an elastic thrust towards the positioning frame 46, ensuring the locking block 45 remains locked to the positioning frame 46 under normal conditions, guaranteeing reliable locking.

[0026] A locking block 45 is fixedly installed at one end of the sliding column 42 near the storage cylinder 2, and a positioning frame 46 is fixedly installed at one end of the rotating cylinder 32 located in the inner cavity of the support frame 1. The locking block 45 and the positioning frame 46 are positioned and adapted to each other. The outer surface of the locking block 45 has several protrusions, which fit tightly against the inner cavity of the positioning frame 46. The locking block 45 can be inserted into or removed from the positioning frame 46 as the sliding column 42 moves, achieving a positioning and locking effect. By setting the positioning frame 46, when the locking block 45 is inserted into the positioning frame 46, the rotating cylinder 32 is locked and cannot rotate; when the locking block 45 is removed from the positioning frame 46, the rotating cylinder 32 can rotate freely, realizing the control of the opening and closing of the protective net 33.

[0027] A torque limiter 47 is fixed to the outer surface of the positioning frame 46. A rotating ring 48 is fixed to the movable end of the torque limiter 47. A wire rope 411 is fixed to the outer surface of the rotating ring 48. A fixed frame 49 is fixed to the outer surface of the support frame 1. A guide tube 410 passes through the outer surface of the fixed frame 49. The end of the wire rope 411 passes through the inner cavity of the guide tube 410 and exits from the end of the guide tube 410. By setting the torque limiter 47, when the rotating drum 32 rotates, the torque limiter 47 drives the rotating ring 48 to rotate with the torque limiter 47, which is used to wind up or release the wire rope 411, converting the rotational motion of the rotating drum 32 into the tensioning motion of the wire rope 411. By setting the wire rope 411, the rotating ring 48 is connected to the sliding block 63, and the rotational force of the rotating drum 32 is transmitted to the anchoring mechanism 6. By setting the guide tube 410, a guide channel is provided for the wire rope 411, ensuring that the wire rope 411 slides smoothly along the predetermined path and avoids tangling.

[0028] A connecting frame 61 is fixedly mounted on the upper surface of the support plate 5. A limiting tube 62 is fixedly mounted on the top of the connecting frame 61. A sliding block 63 is slidably connected to the inner cavity of the limiting tube 62. A second spring 64 is fixedly mounted on the surface of the sliding block 63, and the end of the second spring 64 is fixed to the inner wall of the limiting tube 62. The end of the steel wire rope 411 away from the rotating ring 48 is fixed to the outer surface of the sliding block 63. By setting the limiting tube 62, the sliding block 63 is limited, providing a linear sliding guide for the sliding block 63 and ensuring that the sliding block 63 moves stably in a predetermined direction. By setting the sliding block 63, it slides along the limiting tube 62 under the pull of the steel wire rope 411, ultimately driving the connecting rod 65 and the rack plate 66 to move. By setting a second spring 64, which is sleeved inside the limiting tube 62, an elastic thrust is provided to the sliding block 63 in the direction of the wire rope 411. When the wire rope 411 is slack, the sliding block 63 is pushed to reset, so that the rack plate 66 returns to its original position, thereby realizing the automatic unlocking of the anchoring mechanism 6.

[0029] A connecting rod 65 is fixed to the side of the sliding block 63 away from the wire rope 411. The connecting rod 65 is located on the outer surface of the limiting tube 62. A rack plate 66 is fixed to the end of the connecting rod 65. A row of teeth is provided on both sides of the outer side of the rack plate 66. A positioning frame 67 is fixed to the upper surface of the support plate 5. The rack plate 66 is slidably connected to the outer surface of the positioning frame 67. The teeth on the outer side of the rack plate 66 mesh with the gear 693. By setting the connecting rod 65, the sliding block 63 and the rack plate 66 are connected, and the sliding motion of the sliding block 63 is transmitted to the rack plate 66. By setting the rack plate 66, which has teeth on both sides of its outer side, it slides along the positioning frame 67 under the drive of the connecting rod 65 and meshes with the gear 693, converting the linear motion of the rack plate 66 into the rotational motion of the gear 693, driving the internally threaded tube 692 to rotate. By setting a positioning bracket 67, which is fixed on the upper surface of the support plate 5, a precise linear motion guide is provided for the rack plate 66, ensuring the meshing accuracy between the rack plate 66 and the gear 693.

[0030] A hammering plate 610 is fixed to the top of the anchoring pipe 68, and a screw 694 is threadedly connected to the inner cavity of the internally threaded pipe 692. A compression ring 695 is fixed to the bottom end of the screw 694. The hammering plate 610 bears the hammering force when the anchoring pipe 68 is driven into the slope soil, protecting the end of the anchoring pipe 68 from direct hammering damage, while simultaneously distributing the hammering force evenly to the anchoring pipe 68. The screw 694, threadedly engaged with the internally threaded pipe 692, moves axially as the internally threaded pipe 692 rotates, pushing the compression ring 695 up and down. The compression ring 695, as the screw 694 moves downward, compresses the inner surface of the rotating plate 697, ultimately causing the rotating plate 697 to open outward, forming an anchoring force.

[0031] The outer surface of the anchor tube 68 has four evenly distributed slots. A limiting frame 696 is fixed to the inner wall of the anchor tube 68. A rotating plate 697 is rotatably connected to the outer surface of the limiting frame 696. The rotating plate 697 is rotatably connected to the slots on the outer surface of the anchor tube 68. The compression ring 695 is compressionally fitted to the inner surface of the rotating plate 697. A fixing post 698 is fixed to the bottom surface of the inner cavity of the anchor tube 68. A third spring 699 is fixed to the outer surface of the fixing post 698. The end of the third spring 699 is fixed to the bottom end of the rotating plate 697. A hexagonal prism 6910 is fixed to the top of the fixing post 698. The hexagonal prism 6910 is slidably connected to the inner cavity of the compression ring 695 and the lead screw 694. By setting the slots on the outer surface of the anchor tube 68, an outward opening channel is provided for the rotating plate 697, allowing the rotating plate 697 to extend from the surface of the anchor tube 68 and embed into the soil. By setting a limiting frame 696, a rotational support is provided for the rotating plate 697, enabling the rotating plate 697 to rotate stably around the limiting frame 696. The rotating plate 697 can rotate around the limiting frame 696, opening outwards when the compression ring 695 presses down, ultimately inserting the rotating plate 697 into the soil. When the compression ring 695 moves upwards, it retracts and resets under the action of the third spring 699. The third spring 699 connects the fixing column 698 to the bottom end of the rotating plate 697, pulling the rotating plate 697 to retract and reset when the compression ring 695 moves upwards, facilitating the retrieval of the anchoring tube 68. A hexagonal prism 6910 is fixed to the top of the fixing column 698 and slidably connected to the inner cavity of the compression ring 695 and the lead screw 694, serving as a rotation drive interface. This allows the lead screw 694 to be rotated using an external wrench, while maintaining coaxial guidance during rotation.

[0032] Working principle: During installation, the anchoring pipe 68 is first driven into the slope soil and rock mass through the hammer plate 610. It embeds itself into the soil and rock mass to form initial anchoring force. Pulling the pull rod 43 causes the sliding column 42 to move the locking block 45 away from the positioning frame 46, releasing the lock of the rotating cylinder 32. Holding the handle 35, pull the fixing plate 34, and the protective net 33 is pulled out from the inner cavity of the receiving cylinder 2 through the discharge port 7, and laid downwards along the slope surface. After the net is in place, the anchoring plate 36 is inserted into the slope soil to fix the end of the protective net 33. The curved bottom end of the anchoring plate 36 faces the receiving cylinder 2 to prevent the protective net 33 from springing back and curling.

[0033] During the netting process, the rotation of the rotating drum 32 drives the rotating ring 48 to rotate via the torque limiter 47, winding up the wire rope 411. The wire rope 411 pulls the sliding block 63 along the limiting tube 62 via the guide tube 410, overcoming the elastic force of the second spring 64, and drives the rack plate 66 to move along the positioning frame 67 via the connecting rod 65. The rack plate 66 meshes with the gear 693, driving the internal thread tube 692 to rotate, causing the screw 694 and the compression ring 695 to continue to press down, further increasing the opening angle of the rotating plate 697, so that the anchoring force of the anchoring tube 68 increases synchronously with the tension of the protective netting 33, forming a prestressed reinforcement system.

[0034] After the net is in place, release the pull rod 43. The first spring 44 pushes the locking block 45 into the positioning frame 46, locking the rotating cylinder 32 and maintaining the tension of the protective net 33. The torque limiter 47 automatically slips when the torque exceeds the set value to prevent the wire rope 411 from breaking due to overload.
