Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, and in particular to an anchoring device for preventing landslide geological disasters. Background Technology

[0002] In recent years, with the rapid development of infrastructure construction, slope stability issues have become increasingly prominent, and landslides have occurred frequently, seriously threatening people's lives and property. Traditional slope reinforcement techniques often employ concrete retaining walls, anti-slide piles, or rigid anchoring structures. While these methods can provide some support, they still have significant drawbacks in practical applications. For example, traditional anchoring devices often use integral or rigid connection designs, resulting in large individual component weights and difficulties in transportation, especially in complex terrain where construction efficiency is low. Rigid connections are prone to localized stress concentration, and under long-term geological deformation or vibration, node breakage can easily occur, affecting overall stability. Furthermore, existing devices are difficult to flexibly adapt to terrain changes with different slope gradients, and subsequent maintenance or adjustment costs are high, limiting their large-scale application.

[0003] While some existing patented technologies have attempted modular anchoring devices, their structures still rely heavily on rigid connections such as bolts and welding, resulting in cumbersome assembly and disassembly and an inability to effectively distribute stress. Some solutions employ a grid-like layout, but the complex node design leads to long construction cycles and poor economic efficiency. Furthermore, existing technologies are insufficiently adaptable to dynamic geological deformation, lack buffering mechanisms, and are prone to failure due to stress fatigue during long-term use. Therefore, there is an urgent need for a lightweight, modular anchoring device with flexible stress-dispersing capabilities to improve construction efficiency, reduce costs, and enhance long-term stability. Summary of the Invention

[0004] To address the technical problems mentioned in the background art, the present invention provides an anchoring device for preventing landslide geological disasters.

[0005] The present invention is achieved by the following technical solution: an anchoring device for preventing landslide geological disasters, which is set on the slope and distributed in a grid pattern, and is formed by splicing together several anchoring units. The anchoring unit includes an anchor support and four side frames, which are evenly distributed around the anchor support, and the anchor support and the side frames are detachably connected.

[0006] The anchor support has a central hole, and an anchor rod inserted into the slope is installed at the central hole.

[0007] Each pair of adjacent frames is connected by a set of reinforcing mechanisms.

[0008] This solution utilizes detachable anchor supports and frames to form individual anchoring units, which are then spliced ​​together to form a grid-like anchoring system. This facilitates assembly and disassembly. The connections between the structures are not all rigid, which helps to distribute stress, facilitates rapid construction and subsequent maintenance, and provides excellent slope protection.

[0009] As a further improvement to the above solution, the anchor support is a circular structure. An annular groove is provided on the annular sidewall of the anchor support. A flexible connecting ring is installed in the annular groove by a number of clamping parts. The circumference of the flexible connecting ring is greater than the circumference of the anchor support. Under the constraint of the clamping parts, a sleeve is formed between the flexible connecting ring and the outer wall of the frame, which is the same number as the frame. Each frame and the corresponding sleeve are connected by a detachable unit.

[0010] The above-mentioned flexible connection method reduces stress concentration at the contact point between the anchor rod and the frame, resulting in good performance and easy assembly and disassembly. It also avoids the use of other hardware connectors, saving costs.

[0011] As a further improvement to the above solution, the clamping member is an "M"-shaped rod, and the clamping member includes an end, a middle part and a plug fixed at the end. The end can be fully inserted into the annular groove so that part of the flexible connecting ring is always located in the annular groove. The plug and the anchor support are detachably connected.

[0012] The "M" clamping element can quickly tighten the flexible connecting ring to form a sleeve, making the operation simple and convenient.

[0013] As a further improvement to the above solution, a pin groove is provided on the plug, and a mating hole corresponding to the plug is provided on the annular side wall of the anchor support. A positioning hole communicating with the mating hole is provided on the end face of the anchor support. A positioning pin can be installed at the positioning hole. The end of the positioning pin can cooperate with the pin groove on the plug that extends into the mating hole, thereby fixing the position of the clamping part.

[0014] As a further improvement to the above solution, the flexible connecting ring is made of steel cable or high-strength nylon rope.

[0015] As the clamping component is gradually inserted into the mating hole along with the plug, its middle part can squeeze part of the flexible connecting ring into the annular groove. This can effectively prevent the flexible connecting ring from separating from the annular groove, and the position of the clamping component can be quickly fixed by using the locating pin.

[0016] As a further improvement to the above solution, the detachable unit connection includes a fixed rod and a movable rod. The fixed rod and the movable rod can be closed to form a loop, which can be connected to the sleeve. Two holes are provided on the end face of the frame. One hole is fixedly connected to the fixed rod, and the other hole is slidably connected to the movable rod. A slot is provided on the fixed rod, and a kit is fixed on the movable rod. A lever is hinged to the outside of the kit. The other end of the lever moves through the slot, and the middle part of the lever is rotatably connected to the inner wall of the slot. Rotating the lever causes the movable rod to slide along the corresponding hole.

[0017] As a further improvement to the above scheme, a hinge block is movably provided on the inner wall of the slot, and the middle part of the lever is rotatably connected to the hinge block through a pin.

[0018] As a further improvement to the above solution, the strengthening mechanism includes an arc-shaped reinforcing rod and two sets of connecting modules respectively installed at both ends of the reinforcing rod. The connecting modules are used to connect with the holes opened on the side of the frame.

[0019] As a further improvement to the above solution, the connecting module includes a through rod that passes through the reinforcing rod, two intermediate rods fixed at both ends of the through rod, and a mounting plate connected to the ends of the two intermediate rods. The mounting plate has a mounting hole in the middle, and a connecting post passes through the mounting hole. An end cap is provided at one end of the connecting post near the reinforcing rod. A buffer spring is also installed on the outside of the connecting post between the end cap and the mounting plate. The other end of the connecting post is connected to the hole.

[0020] As a further improvement to the above scheme, hole position two is a threaded hole, and the connecting post and hole position two are connected by a spiral.

[0021] This invention can further suppress landslide displacement and deformation through the strengthening mechanism, improve the overall deformation resistance of the device, and the strengthening mechanism is also convenient for installation and disassembly of the frame. The device forms an anchoring system with the frame, anchor support and strengthening mechanism as the main components. The modular design facilitates assembly and later maintenance, and the low cost makes it easy to promote and use on a large scale.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention adopts a modular structural design. Specifically, it uses a combination of detachable anchor supports and frame, resulting in a small weight per node, easy portability, and convenient manual handling and rapid assembly. Furthermore, the grid-like splicing system formed by this solution can adapt to different slope terrains, effectively improving construction efficiency.

[0024] This invention also has the ability to distribute flexible stress. It uses a flexible connecting ring made of steel cable or nylon rope to replace the traditional rigid connector, which reduces stress concentration at the nodes. In addition, it adopts an "M" shaped clamping part and an annular groove design to allow the structure to deform dynamically within a certain range without failure.

[0025] The present invention also designs a dual reinforcement system. Its main structure is an anchor support that provides pull-out resistance through a prestressed anchor. The reinforcement mechanism, namely the combination of an arc-shaped reinforcing rod and a buffer spring, can further improve the service life of the device. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Reference Figures 1-6 The anchoring device for preventing landslide geological disasters proposed in this embodiment is set on the slope and distributed in a grid pattern. It is formed by splicing together several anchoring units. The anchoring unit includes an anchor support 2 and four side frames 1. The four side frames 1 are evenly distributed around the anchor support 2, and the anchor support 2 and the side frames 1 are detachably connected.

[0037] In this scheme, a central hole 10 is provided in the anchor support 2, and an anchor 4 inserted into the slope is installed at the central hole 10.

[0038] To achieve higher strength, each of the two adjacent frame frames 1 is connected by a set of reinforcing mechanisms 3.

[0039] This scheme utilizes detachable anchor supports 2 and frame 1 to form individual anchoring units, and then splices several anchoring units to form a grid-like anchoring system, which is easy to assemble and disassemble. The connections between the structures are not all rigid contacts, which can disperse stress, facilitate rapid construction and subsequent maintenance, and at the same time have a good slope protection effect.

[0040] In a preferred embodiment of the present invention, the anchor support can be a circular structure with a diameter of Φ200mm, made of Q345B steel. The frame dimensions are: L×W×H=2000×150×100mm, made of Q345B steel. The flexible connecting ring is made of high-strength steel cable with a nominal diameter of 16mm (breaking force ≥250kN). The reinforcing rod has an arc-shaped design with a radius of curvature greater than 2m, made of Q345B steel.

[0041] Before construction, site leveling is required: remove surface soil, control the slope within the design range, and then conduct surveying and layout: locate the center point of the anchor support according to the design grid spacing (2m×2m recommended); the installation of the anchor support can be carried out according to the following steps, which can also be adjusted according to the actual situation during construction:

[0042] Drilling: M30 cement mortar anchor rods are used, with a drilling depth of ≥6m;

[0043] Grouting: Grouting pressure 0.5~1.0MPa, grout water-cement ratio 0.45~0.5;

[0044] Support fixing: The anchor support is locked to the anchor head by the positioning pin, and the verticality deviation is ≤1°.

[0045] In this design, the anchor support 2 is a circular structure. An annular groove 13 is formed on the annular sidewall of the anchor support 2. Flexible connecting rings 5 ​​are installed in the annular groove 13 via several sets of clamping elements 6. The circumference of the flexible connecting rings 5 ​​is greater than the circumference of the anchor support 2. Under the constraint of the clamping elements 6, a sleeve is formed between the flexible connecting rings 5 ​​and the outer wall of the frame, with the same number of sleeves as the frame 1 (see reference). Figure 3 (Not marked), each frame 1 and its corresponding socket are connected by a detachable unit.

[0046] By adopting the above-mentioned flexible connection method, the stress concentration at the contact point between the anchor rod and the frame is reduced, resulting in good performance and easy disassembly and assembly. This avoids the use of other hardware connectors and saves costs.

[0047] It should be noted that the clamping member 6 is an "M" shaped rod. The body diameter of the clamping member 6 is made of high-strength steel with a diameter of Φ16mm. The clamping member 6 includes an end 601, a middle part 602, and a plug 603 fixed to the end of the end 601. The end 601 can be fully inserted into the annular groove 13 so that part of the flexible connecting ring 5 is always located in the annular groove 13. The plug 603 and the anchor support 2 are detachably connected.

[0048] The clamping element 6 of the "M" can quickly tighten the flexible connecting ring 5 to form a sleeve, which is simple and convenient to operate.

[0049] Specifically, the plug 603 has a pin groove 14, and the annular side wall of the anchor support 2 has a mating hole 202 that corresponds to the plug 603. The end face of the anchor support 2 has a positioning hole 201 that communicates with the mating hole 202. A positioning pin can be installed in the positioning hole 201. The end of the positioning pin can cooperate with the pin groove 14 on the plug 603 that extends into the mating hole 202, thereby fixing the position of the clamping member 6.

[0050] Optionally, the flexible connecting ring 5 can be a steel cable or a high-strength nylon rope.

[0051] As the clamping member 6 is gradually inserted into the mating hole 202 along with the plug 603, its middle part 602 can squeeze part of the flexible connecting ring 5 into the annular groove 13. This can effectively prevent the flexible connecting ring 5 from separating from the annular groove 13, and the position of the clamping member 6 can be quickly fixed by using the positioning pin.

[0052] In an optional embodiment of the present invention, the detachable unit connection includes a fixed rod 7 and a movable rod 11. The fixed rod 7 and the movable rod 11 can be closed to form a U-shaped buckle, which can be connected to a sleeve. Two holes 101 are provided on the end face of the frame 1. One hole 101 is fixedly connected to the fixed rod 7, and the other hole 101 is slidably connected to the movable rod 11. A slot 8 is provided on the fixed rod 7. A kit 12 is fixed on the movable rod 11. A lever 9 is hinged to the outer side of the kit 12. The other end of the lever 9 moves through the slot 8, and the middle part of the lever 9 is rotatably connected to the inner wall of the slot 8. Rotating the lever 9 causes the movable rod 11 to slide along the corresponding hole 101. The kit 12 is made of stainless steel metal ring, and it can be connected to the movable rod 12 by riveting or screwing.

[0053] In this solution, a hinge block is movably provided on the inner wall of the slot 8 (not shown in the figure, but it does not affect the understanding and implementation of the solution by those skilled in the art), and the middle part of the lever 9 is rotatably connected to the hinge block through a pin.

[0054] Furthermore, the reinforcing mechanism 3 includes an arc-shaped reinforcing rod 301 and two sets of connecting modules respectively installed at both ends of the reinforcing rod 301. The connecting modules are used to connect with the holes 102 opened on the side of the frame 1.

[0055] It is worth mentioning that the connecting module includes a through rod 16 that passes through the reinforcing rod 301, two intermediate rods 17 fixed at both ends of the through rod 16, and a mounting plate 18 connected to the ends of the two intermediate rods 17. The mounting plate 18 has a mounting hole in the middle, and a connecting post 20 passes through the mounting hole. An end cap is provided at one end of the connecting post 20 near the reinforcing rod 301. A buffer spring 19 is also installed on the outside of the connecting post 20 between the end cap and the mounting plate 18. The other end of the connecting post 20 is connected to the second hole 102.

[0056] In this design, hole position 2 102 is a threaded hole, and the connecting post 20 and hole position 2 102 are connected by a screw thread.

[0057] The present invention can further suppress landslide displacement deformation by strengthening mechanism 3, improve the overall deformation resistance of the device, and strengthen mechanism 3 is also convenient for installation and disassembly of the frame. The device forms an anchoring system with frame, anchor support 2 and strengthening mechanism 3 as the main components. The modular design facilitates assembly and later maintenance, and the cost is low and it is easy to promote and use on a large scale.

[0058] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
