Description

Technical Field

[0001] This utility model relates to the field of slope protection construction technology, specifically a slope support structure with tilt detection function. Background Technology

[0002] Slope protection structures are engineering structures designed to maintain slope stability and prevent instability and damage. They mainly utilize the strength of the structure itself or its synergistic effect with the soil and rock mass to provide anti-sliding and anti-overturning forces, effectively control deformation, and are widely used in highway, railway, mining and building engineering. They are a key measure for geotechnical engineering safety.

[0003] Currently, mainstream slope protection equipment on the market typically uses welded or bolted rigid connections for the protective netting. The netting installation process relies heavily on manual high-altitude binding and lacks a dedicated quick assembly and disassembly mechanism. Furthermore, traditional fixing methods often result in a permanent fixed connection between the protective netting and the support structure.

[0004] Furthermore, traditional fixing methods lead to a surge in later maintenance costs. Because the protective netting is exposed to the outdoors for a long time, it is susceptible to wear and tear or local damage due to environmental factors such as rockfall impact, wind and rain erosion, and material aging. However, rigid fixing makes it extremely difficult to replace, which not only consumes a lot of manpower, material resources and time, but also causes the slope to be in a state of protection deficiency for a period of time, seriously affecting the timeliness and continuity of protection, and reducing the overall protective effectiveness and service life of the project. Utility Model Content

[0005] The purpose of this invention is to provide a slope support structure with tilt detection function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A slope support structure with tilt detection function includes support anchors. Multiple support anchors are inserted into the inside of the slope body. Each support anchor has a connecting ring installed at one end outside the slope body. The slope surface is covered with a protective net, and the edge of the protective net is connected to the connecting ring by a cable. The soil-entry end of the support anchor has a grouting hole and a drill bit is fixedly connected to it.

[0008] Each of the support anchor rods has a rotating cap threaded onto one end outside the slope body, and an installation assembly is fixedly installed on the outer wall of each rotating cap. Each installation assembly includes a base, which is fixedly installed on the outer wall of the rotating cap. A limit tube is slidably inserted into the inside of the base, and a moving tube is slidably connected to the inner axis of the limit tube. One end of the moving tube outside the limit tube is threadedly connected to a connecting ring, and a displacement sensor is provided at its other end.

[0009] Each of the support anchor rods is fixedly installed with a reinforcement component on its outer wall. Each set of reinforcement components includes multiple reinforcement plates. The multiple reinforcement plates are circumferentially symmetrically and evenly fitted onto the outside of the support anchor rod, and the reinforcement plates are clamped into the hole wall of the slope body.

[0010] As a further embodiment of this utility model, the outer wall of the base is provided with a plurality of limiting holes in the circumferential direction, and a limiting ball is movably embedded in each limiting hole. A limiting groove is correspondingly provided on the outer surface of the limiting tube, and the limiting ball protrudes from one side of the limiting hole and engages with the limiting groove.

[0011] As a further embodiment of this utility model, a control tube is slidably sleeved on the outer surface of the base, and a reset spring is provided between the two. The top end of the reset spring is fixedly connected to the control tube, and the bottom end of the reset spring is fixedly connected to the base. The inner wall of the control tube is provided with a convex ring, and the convex ring and the limiting ball always maintain dynamic contact.

[0012] As a further embodiment of this utility model, a rope clamp is fitted on the outer wall of one end of the cable near the connecting ring, and connecting seats are fitted on both ends of the rope clamp, with a fastening nut threaded onto the end of the rope clamp that passes through the connecting seat.

[0013] As a further embodiment of this utility model, the reinforcement component also includes a fixing component and a moving component. The fixing component is fixedly installed inside the support anchor rod, and the moving component is slidably installed inside the support anchor rod and located above the fixing component. The outer walls of both the fixing component and the moving component are rotatably connected to multiple transmission rods via pins, and the other end of each transmission rod is rotatably connected to the corresponding reinforcement plate via a pin. The support anchor rod has a drive rod threaded into its interior, and the bottom end of the drive rod is rotatably connected to the top surface of the moving component via a bearing.

[0014] As a further embodiment of this utility model, the support anchor rod has multiple fixed rods fixedly installed inside, and each fixed rod is fitted with a contraction spring. Each fixed rod is sequentially fitted with a moving part and a fixed part, and the contraction spring is located between the moving part and the fixed part.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When using the slope support structure of this utility model, the self-locking and quick-release of the protective netting is achieved through the installation components, so that the replacement of damaged protective netting no longer depends on large machinery or complex manual operations. It can be completed simply by turning the control tube, which effectively improves the efficiency and safety of replacing damaged protective netting in complex field environments. At the same time, the displacement sensor can collect the slight deformation of the slope to realize the tilt detection function and ensure the real-time monitoring of the slope.

[0017] 2. When the slope support structure of this utility model is used, the mechanical linkage between the drive rod and the transmission rod in the reinforcement component realizes the active radial expansion of the reinforcement plate, so that it is tightly embedded in the hole wall, effectively enhancing the mechanical compressive force and pull-out force of the support anchor. Combined with the automatic reset function of the contraction spring, it not only ensures the anchoring stability under complex strata, but also effectively prevents accidental jamming during the installation process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 In this embodiment of the utility model, a slope support structure with tilt detection function includes support anchor rods 2. Multiple support anchor rods 2 are inserted into the inside of the slope body 1 and penetrate deep into the slope body 1 to provide anchoring force. Each support anchor rod 2 has a connecting ring 3 installed at one end outside the slope body 1. The slope surface of the slope body 1 is covered with a protective net 4 to cover the slope surface to prevent surface gravel from rolling down or eroding. The edge of the protective net 4 is connected to the connecting ring 3 by a cable 5. The soil-entry end of the support anchor rod 2 is provided with a grouting hole and is fixedly connected with a drill bit 9.

[0030] Each support anchor rod 2 has a rotating cover 6 threaded on one end outside the slope body 1, and an installation component 7 is fixedly installed on the outer wall of each rotating cover 6 for convenient installation, removal and replacement of the protective net 4. Since the protective net 4 is in contact with the surface of the slope body 1 for a long time, friction can easily cause it to break. The installation component 7 facilitates timely replacement of the protective net 4, effectively solving the problem of difficult replacement of traditional protective net 4 due to long-term wear, so as to maintain the protective performance. Each set of installation components 7 includes a base 701, which is fixedly installed on the outer wall of the rotating cover 6. A limit tube 702 is slidably inserted inside the base 701 for quick positioning and locking. A moving tube 703 is slidably connected at the inner axis of the limit tube 702. One end of the moving tube 703 outside the limit tube 702 is threadedly connected to the connecting ring 3, and the other end is equipped with a displacement sensor for monitoring the slope tilt status.

[0031] Each support anchor 2 is fixedly installed with a reinforcement component 8 to enhance its anchoring force. Each reinforcement component 8 includes multiple reinforcement plates 801 to enhance the pull-out resistance and stability of the support anchor 2. The multiple reinforcement plates 801 are circumferentially symmetrically and evenly sleeved on the outside of the support anchor 2, and the reinforcement plates 801 are stuck in the hole wall of the slope body 1.

[0032] It should be noted that the inner cavity of the slope body 1 is provided with multiple anchor bolt holes, and each support anchor bolt 2 is located in the anchor bolt hole. Through the drill bit 9 and the grouting hole, the drilling and grouting are integrated, which improves the hole formation efficiency and grout fullness of the fractured strata. In conjunction with the support anchor bolt 2 and the reinforcement plate 801 on its outer periphery, the contact area with the soil can be increased, forming a stable load-bearing skeleton inside the slope body 1.

[0033] It should also be noted that when the slope 1 undergoes displacement or unstable creep, the tension generated by the slope displacement acts on the protective net 4 in real time, and the stress is transmitted to the connecting ring 3 through the cable 5, thereby driving the moving pipe 703, which is linked to it, to produce synchronous displacement. During this process, the displacement vector of the moving pipe 703 is collected in real time by the displacement sensor, so as to provide real-time feedback on the displacement state of the slope 1 and realize the tilt detection function.

[0034] Please see Figure 3 , Figure 4 The outer wall of the base 701 is provided with multiple limiting holes in the circumferential direction, and a limiting ball 704 is movably embedded in each limiting hole. A limiting groove 705 is correspondingly provided on the outer surface of the limiting tube 702, and the limiting ball 704 protrudes from one side of the limiting hole and engages with the limiting groove 705, thereby realizing the axial locking and horizontal limiting of the limiting tube 702.

[0035] It should be noted that magnetic rings 706 with magnetic attraction are fixedly embedded in the inner bottom surface of the base 701 and the insertion end of the limiting tube 702. The magnetic attraction further strengthens the connection between the two and prevents loosening under vibration or complex load conditions. Through the dual locking mechanism of mechanical ball lock and magnetic attraction, the installation component 7 can be quickly stabilized and reset.

[0036] A control tube 707 is slidably sleeved on the outer surface of the base 701, and a return spring 708 is provided between the two. The top end of the return spring 708 is fixedly connected to the control tube 707, and the bottom end of the return spring 708 is fixedly connected to the base 701. The inner wall of the control tube 707 is provided with a convex ring, and the convex ring and the limiting ball 704 always maintain dynamic contact. Under the action of the return spring 708, the control tube 707 is pushed to press the convex ring on the outside of the limiting ball 704, forcing the limiting ball 704 to be locked inward in the limiting groove 705.

[0037] It should be noted that under normal conditions, the return spring 708 drives the control tube 707 to apply radial pressure to the limit ball 704 to ensure a stable connection and prevent the protective net 4 from falling off under force. When the protective net 4 needs to be replaced, simply manually move the control tube 707 to compress the return spring 708 so that the convex ring avoids the limit ball 704, thereby releasing the mechanical lock and realizing the self-locking and quick-release function of the protective net 4, effectively improving the maintenance efficiency of high-altitude or steep slope operations.

[0038] It should also be noted that a sealing ring 709 is embedded on the top outer surface of the base 701, and the sealing ring 709 is tightly fitted to the mating gap between the control tube 707 and the base 701, forming an annular barrier. This barrier is designed to prevent external dust, rainwater and debris from entering the sliding space inside the base 701, ensuring the smooth reciprocating sliding between the control tube 707 and the base 701, and effectively solving the mechanical jamming and corrosion problems caused by dust and moisture in harsh outdoor environments.

[0039] A limiting plate is fixedly connected to one end of the moving tube 703 away from the connecting ring 3. A resistance spring 710 is provided on the top surface of the limiting plate, and the other end of the resistance spring 710 is fixedly connected to the inner wall of the limiting tube 702. A moving guide tube is provided inside the limiting tube 702 to ensure that the moving tube 703 performs stable vertical reciprocating motion in the axial direction.

[0040] It should be noted that the displacement sensor is fixedly installed on the top surface of the limiting plate. When the slope 1 is displaced, the cable 5 is stressed and drives the moving tube 703 to move outward of the limiting tube 702 against the spring force of the resistance spring 710. The limiting plate moves accordingly and contacts the sensing contact of the moving tube, thereby triggering the displacement sensor to send a signal. The displacement sensor detects the relative displacement between the moving tube 703 and the limiting tube 702 to determine whether the slope 1 has become unstable or tilted. In addition, the resistance spring 710 is always kept in a slightly compressed pre-tight state under normal conditions to filter out the small fluctuations of the protective net 4 caused by natural wind and other factors, and to prevent false alarms.

[0041] It should also be noted that the moving tube 703 is a hollow tube, and a battery is housed inside it. The battery is electrically connected to the displacement sensor to provide a continuous power supply for the entire monitoring unit.

[0042] Please see Figure 5 A rope clamp 51 is fitted on the outer wall of the end of the cable 5 near the connecting ring 3 to reinforce the connection between the cable 5 and the connecting ring 3 at the suspension point. Connecting seats 52 are fitted on both ends of the rope clamp 51, and a fastening nut 53 is threaded on the end of the rope clamp 51 that passes through the connecting seat 52. The fastening nut 53 is used to limit the axial displacement and loosening of the connecting seat 52 relative to the rope clamp 51.

[0043] It should be noted that the end of the cable 5 near the connecting ring 3 is bent into a circular shape as a hoisting part that is attached to the connecting ring 3. The rope clamp 51 adopts a U-shaped structure design. The cable 5 is inserted into the U-shaped groove of the rope clamp 51. Through the clamping action of the rope clamp 51, the pull-out resistance and anti-detachment ability of the circular structure of the cable 5 are enhanced. In conjunction with the mechanical locking of the connecting seat 52 and the fastening nut 53, the overall structural stability and stress transmission reliability of the connection between the cable 5 and the connecting ring 3 are effectively improved.

[0044] Please see Figure 2 , Figure 6 The reinforcement component 8 also includes a fixing member 802 and a moving member 803. The fixing member 802 is fixedly installed inside the support anchor rod 2, and the moving member 803 is slidably installed inside the support anchor rod 2 and is located above the fixing member 802. The outer walls of the fixing member 802 and the moving member 803 are rotatably connected by pins to multiple transmission rods 804 for pushing the reinforcement plate 801 to expand. The other end of each transmission rod 804 is rotatably connected to the corresponding reinforcement plate 801 by a pin. The support anchor rod 2 has a drive rod 805 for driving the moving member 803 to move, and the bottom end of the drive rod 805 is rotatably connected to the top surface of the moving member 803 by a bearing.

[0045] It should be noted that the top of the drive rod 805 is fixedly connected to the rotating cover 6. The rotation of the drive rod 805 drives the moving part 803 to move, which in turn drives the transmission rod 804 to push the reinforcing plate 801 radially towards the wall of the anchor bolt hole, so that the reinforcing plate 801 is tightly embedded in the wall of the slope hole, thereby forming mechanical extrusion force and effectively providing a reliable anchoring foundation.

[0046] It should also be noted that when the reinforcing plate 801 is fully unfolded, the bottom end of the moving part 803 is inserted into the fixing part 802, and the interior of both and the driving rod 805 are hollow structures and connected to the grouting hole so that the grout can be sprayed directly from the top of the driving rod 805 to the grouting hole.

[0047] The support anchor 2 has multiple fixed rods 806 internally fixed, and each fixed rod 806 is fitted with a contraction spring 807. Each fixed rod 806 is sequentially fitted with a moving part 803 and a fixed part 802, and the contraction spring 807 is located between the moving part 803 and the fixed part 802. In the non-working state, the contraction spring 807 uses its elasticity to push the moving part 803 to maintain the maximum distance between it and the fixed part 802, thereby constraining the transmission rod 804 and preventing the reinforcing plate 801 from accidentally expanding radially outward. This keeps the reinforcing plate 801 in a contracted state, effectively avoiding equipment jamming or damage caused by the reinforcing plate 801 accidentally opening during transportation, hoisting, or drilling insertion.

[0048] The working principle of this utility model is as follows:

[0049] When this utility model is used, firstly, in the initial installation stage, by rotating the drive rod 805, the moving part 803 is driven to move axially along the fixed rod 806. At this time, the contraction spring 807 is compressed, the distance between the moving part 803 and the fixed part 802 is reduced, and the transmission rod 804 is driven to unfold, so that the reinforcing plate 801 is radially expanded and tightly inserted into the hole wall of the slope body 1. Then, grouting is performed, and the grout is sprayed directly from the top of the drive rod 805 to the grouting hole, so that the support anchor 2, the reinforcing component 8 and the soil form a stable force-bearing whole.

[0050] Then, the protective net 4 is fixedly connected to the connecting ring 3 by the anti-detachment structure consisting of the cable 5, rope clamp 51, and fastening nut 53, and the limiting tube 702 is inserted into the base 701. The control tube 707 is used to press the limiting ball 704 into the limiting groove 705 under the action of the return spring 708. With the adsorption of the magnetic ring 706, the limiting tube 702 is firmly locked in the base 701, thereby realizing the quick hanging of the protective net 4.

[0051] When the slope 1 becomes unstable and shifts or tilts, the resulting lateral pressure directly pulls the protective net 4. The tension is transmitted to the connecting ring 3 through the cable 5. The connecting ring 3 drives the moving pipe 703 to overcome the preload of the resistance spring 710 and undergo linear displacement under the constraint of the moving guide pipe. The limiting plate moves accordingly and triggers the displacement sensor. The displacement sensor obtains the displacement vector signal by detecting the relative displacement between the moving pipe 703 and the limiting pipe 702, and then sends it to the cloud server for real-time early warning.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
