Description

Technical Field

[0001] The present invention relates to the technical field of slope reinforcement, and particularly to an anchoring device for preventing landslide geological disasters. Background Art

[0002] In recent years, with the rapid development of infrastructure construction, the problem of slope stability has become increasingly prominent, and landslide geological disasters occur frequently, seriously threatening people's lives and property safety. Traditional slope reinforcement technologies often use concrete retaining walls, anti-slide piles or rigid anchoring structures. Although these methods can provide certain support effects, there are still significant defects in practical applications. For example, traditional anchoring devices mostly adopt integral or rigid connection designs, resulting in large single-piece weights and difficult handling, especially with low construction efficiency in complex terrains; rigid connections are prone to cause local stress concentration, and when affected by geological deformation or vibration for a long time, node fractures are likely to occur, affecting the overall stability; in addition, existing devices are difficult to flexibly adapt to terrain changes with different slopes, and the later maintenance or adjustment costs are high, restricting their large-scale application.

[0003] In existing patented technologies, although there are some attempts at modular anchoring devices, their structures still rely on a large number of rigid connection methods such as bolts and welding, which are cumbersome to disassemble and assemble and cannot effectively disperse stress. Some schemes adopt a grid layout, but the node design is complex, resulting in a long construction period and poor economy. In addition, the existing technologies are insufficient in adapting to dynamic geological deformation and lack a buffering mechanism, and are prone to failure due to stress fatigue during long-term use. Therefore, there is an urgent need for a lightweight, modular and flexible stress-dispersing anchoring device to improve construction efficiency, reduce costs and enhance long-term stability. Summary of the Invention

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

[0005] The present invention is realized by the following technical solutions: An anchoring device for preventing landslide geological disasters is provided, which is arranged on a slope and distributed in a grid pattern, and is formed by splicing a plurality of anchoring units. Each anchoring unit includes an anchor rod support and four side frames. The four side frames are evenly distributed around the anchor rod support, and the anchor rod support and the side frames are detachably connected;

[0006] A central hole is provided in the anchor rod support, and an anchor rod inserted into the slope body is installed at the central hole;

[0007] Adjacent two side frames are connected by a set of strengthening mechanisms.

[0008] This solution uses detachable bolt supports and frames to form individual anchoring units, and then several anchoring units are spliced to form a grid-like anchoring system, which is convenient for disassembly and assembly. The connections between structures do not all use rigid contacts, which can disperse stress, facilitate rapid construction and subsequent maintenance, and at the same time have a good slope protection effect.

[0009] As a further improvement of the above solution, the bolt support is a circular structure. An annular groove is provided on the annular side wall of the bolt support. A flexible connection ring is installed at the annular groove through several groups of clamping members. The circumference of the flexible connection ring is greater than the circumference of the bolt support. Under the restraint of the clamping members, sleeves corresponding to the number of frames are formed between the flexible connection ring and the outer wall of the frame. Each frame and the corresponding sleeve are connected through a detachable unit.

[0010] Adopting the above flexible connection method reduces the stress concentration at the contact part between the bolt and the frame, has good use effect and is convenient for disassembly and assembly, avoids using other hardware connectors, and saves costs.

[0011] As a further improvement of the above solution, the clamping member is an "M"-shaped rod, and the clamping member includes an end part, a middle part, and a plug fixed at the end of the end part. Among them, the end part can completely extend into the annular groove so that part of the flexible connection ring is always located in the annular groove, and the plug is detachably connected to the bolt support.

[0012] The "M"-shaped clamping member can quickly tighten the flexible connection ring to form a sleeve, and the operation is simple and convenient.

[0013] As a further improvement of the above solution, a pin groove is provided on the plug. A docking hole corresponding to the plug is provided on the annular side wall of the bolt support. A positioning hole communicating with the docking hole is provided on the end face of the bolt support. A positioning pin can be installed at the positioning hole, and the end of the positioning pin can cooperate with the pin groove on the plug extending into the docking hole, so that the position of the clamping member is fixed.

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

[0015] When the clamping member is gradually inserted into the docking hole along with the plug, its middle part can squeeze part of the flexible connection ring into the annular groove, which can effectively prevent the flexible connection ring from separating from the annular groove, and the position of the clamping member can be quickly fixed by using the positioning pin.

[0016] As a further improvement of the above scheme, the detachable unit connection includes a fixed rod and a movable rod, and the fixed rod and the movable rod can be closed to form a paper buckle, and the paper buckle can be connected to the sleeve. Two hole positions 1 are provided on the end face of the frame, one of the hole positions 1 is fixedly connected to the fixed rod, and the other hole position 1 is slidably connected to the movable rod, and a slot is provided on the fixed rod, a kit is fixed on the movable rod, and a lever is hinged on the outside of the kit, and the other end of the lever can be moved through the slot, and the middle part of the lever and the inner wall of the slot can be rotatably connected, and the lever is rotated to drive the movable rod to slide along the corresponding hole position 1.

[0017] As a further improvement of the above solution, a hinge block is movably provided on the inner wall of the slot, and the middle part of the shifting rod is rotatably connected to the hinge block via a pin shaft.

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

[0019] As a further improvement of the above scheme, the connecting module includes a through rod passing 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. A mounting hole is opened in the middle of the mounting plate, and a connecting column is passed through the mounting hole. An end cap is provided at one end of the connecting column close to the reinforcing rod. A buffer spring is also installed on the outside of the connecting column between the end cap and the mounting plate. The other end of the connecting column is connected to hole position 2.

[0020] As a further improvement of the above solution, the second hole is a threaded hole, and the connecting column and the second hole are spirally connected.

[0021] The present invention can further suppress landslide displacement and deformation through the reinforcement mechanism, thereby improving the overall deformation resistance of the device. The reinforcement mechanism is also convenient for installation and disassembly with the frame. The device forms an anchoring system with the frame, anchor support and reinforcement mechanism as the main body. The modular design facilitates assembly and subsequent maintenance, is low in cost and easy to promote and use on a large scale.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention adopts a modular structural design. Specifically, it adopts a detachable anchor support and a frame combination. The single node has a small weight, is easy to carry, and is convenient for manual transportation and rapid assembly. In addition, the grid splicing system formed by this solution can adapt to different slope terrains, and the construction efficiency can be effectively improved.

[0024] The present invention also has the ability of flexible stress dispersion, and adopts flexible connecting rings made of steel cables or nylon ropes to replace traditional rigid connectors to reduce stress concentration at nodes. It also adopts an "M"-shaped clamping piece and an annular groove design to allow the structure to dynamically deform within a certain range without failure.

[0025] The present invention also designs a double reinforcement system. Its main structure is that the anchor rod support provides uplift force through prestressed anchor rods. By using the strengthening mechanism, namely, the combination of the arc-shaped strengthening rod and the buffer spring, the service life of the device can be further improved.

SPECIFIC EMBODIMENTS

[0034] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0035] Embodiment 1:

[0036] Referring to Figures 1-6 , the anchoring device for preventing landslide geological disasters proposed in this embodiment is arranged on the slope and distributed in a grid pattern, and is formed by splicing a plurality of anchoring units. Each anchoring unit includes an anchor rod support 2 and four frames 1. The four frames 1 are evenly distributed around the anchor rod support 2, and the anchor rod support 2 and the frame 1 are detachably connected.

[0037] In this solution, a central hole 10 is provided inside the anchor rod support 2, and an anchor rod 4 inserted into the slope is installed at the central hole 10;

[0038] In order to have higher strength, a set of strengthening mechanisms 3 are used to connect between two adjacent frames 1.

[0039] This solution uses the detachable connection of the anchor rod support 2 and the frame 1 to form individual anchoring units, and then several anchoring units are spliced to form a grid-like anchoring system, which is convenient for disassembly and assembly. The connections between the structures do not all use rigid contact, which can disperse stress, facilitate rapid construction and later maintenance, and at the same time have a good slope protection effect.

[0040] As a preferred embodiment of the present invention, the anchor rod support can adopt a circular structure with a diameter of Φ200mm, and the material is Q345B steel. Frame size: L×W×H = 2000×150×100mm, material Q345B, flexible connection ring: high-strength steel cable with a nominal diameter of 16mm (breaking force ≥ 250kN), strengthening rod: arc design, curvature radius greater than 2m, material Q345B.

[0041] Before specific construction, site leveling is required: remove the surface floating soil, and control the slope within the design range. Then, carry out measurement and layout: position the center point of the anchor rod support according to the design grid spacing (recommended 2m×2m); for the installation of the anchor rod support, the following steps can be carried out, and specific construction can also be adjusted according to the actual situation:

[0042] Drilling: Use M30 cement mortar anchor rod, and the drilling depth ≥ 6m;

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

[0044] Support fixing: Lock the anchor rod support and the anchor rod head through the positioning pin rod, and the perpendicularity deviation ≤ 1°.

[0045] In this solution, the anchor rod support 2 is of a circular structure. An annular groove 13 is provided on the annular side wall of the anchor rod support 2. A flexible connection ring 5 is installed at the annular groove 13 through several groups of clamping members 6. The circumference of the flexible connection ring 5 is greater than the circumference of the anchor rod support 2. Under the constraint of the clamping members 6, a sleeve mouth (refer to Figure 3 , not marked) with the same number as the frame 1 is formed between the flexible connection ring 5 and the outer wall of the frame. Each frame 1 and the corresponding sleeve mouth are connected through a detachable unit.

[0046] Adopting the above flexible connection method can reduce the stress concentration at the contact part between the anchor rod and the frame, has good use effect and is convenient for disassembly and assembly, avoids using other hardware connectors, and saves costs.

The clamping member 6 includes an end portion 601, an intermediate portion 602, and a plug 603 fixed to the end of the end portion 601. Among them, the end portion 601 can completely extend into the annular groove 13 so that part of the flexible connection ring 5 is always located in the annular groove 13, and the plug 603 and the anchor support 2 are detachably connected.

[0048] Through the "M"-shaped clamping member 6, the flexible connection ring 5 can be quickly tightened to form a sleeve opening, and the operation is simple and convenient.

The end of the positioning pin can cooperate with the pin slot 14 on the plug 603 extending into the docking hole 202, so that the position of the clamping member 6 is fixed.

[0050] Optionally, the flexible connection ring 5 is a steel cable or a high-strength nylon rope.

[0051] When the clamping member 6 is gradually inserted into the docking hole 202 along with the plug 603, its intermediate portion 602 can squeeze part of the flexible connection ring 5 into the annular groove 13, which can effectively prevent the flexible connection 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] As an optional implementation manner 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 loop, and the loop can be connected to the sleeve opening. Two hole positions 101 are provided on the end face of the frame 1. One of the hole positions 101 is fixedly connected to the fixed rod 7, and the other hole position 101 is slidably connected to the movable rod 11. A notch 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 outside of the kit 12, the other end of the lever 9 movably passes through the notch 8, and the middle of the lever 9 is rotatably connected to the inner wall of the notch 8. Rotating the lever 9 drives the movable rod 11 to slide along the corresponding hole position 101. The kit 12 is made of a 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 (not shown in the figure, but it does not affect the understanding and implementation of the solution by those skilled in the art) is movably arranged on the inner wall of the notch 8, and the middle of the lever 9 is rotatably connected to the hinge block through a pin shaft.

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

[0055] It is worth mentioning that the connection module includes a through rod 16 passing through the strengthening 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. A mounting hole is opened in the middle of the mounting plate 18. A connecting column 20 passes through the mounting hole. A end cap is provided at one end of the connecting column 20 close to the strengthening rod 301. A buffer spring 19 is also installed on the outer side of the connecting column 20 between the end cap and the mounting plate 18. The other end of the connecting column 20 is connected to the second hole position 102.

[0056] In this solution, the second hole position 102 is a threaded hole, and the connecting column 20 is screwed to the second hole position 102.
