Description

Technical Field

[0001] This invention belongs to the field of slope protection technology, and more specifically, relates to a high slope protection device and construction method. Background Technology

[0002] High slope protection technology plays a crucial role in building construction. It can significantly reduce the impact of adverse factors on the entire project. Many safety hazards arise during construction in my country, posing a threat to the safety of construction workers and urban residents. High slope protection technology effectively addresses these issues. The widespread application of high slope protection technology, coupled with rapid advancements in construction techniques, has effectively reduced the probability of safety hazards in building projects, improving construction quality and safety to a certain extent and facilitating the smooth progress of the entire construction process.

[0003] Soil-rock anchoring technology, as an important means of high slope support, has significant advantages in improving its stability. In soil-rock anchoring, the tensile force of the structure is mainly transmitted through the anchor cable or the low-lying rock mass near the anchor cable, which can reduce the sliding force of the rock blocks. The anchor rod or anchor cable has a certain prestress, which can reduce the sliding force of the rock blocks, enhance the strength of the soil and rock, and stabilize the slope. Therefore, how to effectively improve the stability of soil and rock on high slopes and avoid the safety hazards caused by soil and rock loosening and sliding is a continuous pursuit in the industry.

[0004] A search revealed Chinese Patent Application Publication No. CN 115538461 A, which discloses a soft rock high slope anchor support system and method. This system includes anchor holes, end enlargement holes, anchor rods, a core cage, and an anchoring section. Anchor holes and end enlargement holes are formed by drilling at designated points on the soft rock high slope. The core cage can support the holes as they are drilled. The anchor rod is snapped into the core cage, and its front end has a top cone and an embossed steel strip, both located within the end enlargement hole. Pulling the rod core connected to the top cone causes the embossed steel strip to form a spherical flower structure. The anchoring section is formed by grouting the anchor holes and end enlargement holes, and includes a rod body anchoring section and an enlarged head anchoring section. This increases the contact area with the surrounding soil, making the support system more firmly bonded to the soil, enhancing the pull-out resistance of the anchor rod and its reinforcement effect on the rock and soil. Simultaneously, it seals the rod body within the soil, preventing soil erosion and ensuring a longer slope protection period.

[0005] For example, Chinese Patent Application No. CN 215053124 U discloses an anchor bolt protection structure for preventing landslides on high slopes. This application includes a fixing mechanism, a disassembly mechanism, and an adjustment mechanism. The disassembly mechanism is located on the right side of the fixing mechanism, and the adjustment mechanism is located on the left side. The adjustment mechanism includes a slot located in the middle of the surface of the fixing mechanism. In this anchor bolt protection structure for preventing landslides on high slopes, after the anchor bolt is fixed, the user can disassemble the fixing cylinder and threaded rod by screwing on the connecting plate and connecting frame, facilitating the inspection and replacement of the connecting plate, connecting frame, and their surface parts. The user slides the lower hook along the groove to adjust the metal mesh to a suitable position. Then, rotating the rotating rod causes it to move upwards. Since the rotating rod forms a rotating structure through the fixed plate and the rotating groove, the rotation of the rotating rod does not affect the upward movement of the movable plate. When the limiting block at the upper end of the movable plate passes through the limiting hole, the lower hook can be fixed.

[0006] The above applications all involve technical improvements to high slope protection, but there is still room for optimization. Technical research on high slope protection within the industry has never stopped. Summary of the Invention

[0007] 1. The problem to be solved

[0008] In view of at least some of the problems existing in the prior art, the present invention proposes a high slope protection device and construction method, the purpose of which is to solve the problem that the soil and rock of high slopes are prone to loosening or even sliding in existing construction projects, thereby causing various safety accidents such as slope structure collapse.

[0009] 2. Technical Solution

[0010] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0011] A high slope protection device of the present invention includes an anchor and a first reinforcement mechanism disposed on the anchor.

[0012] The anchor includes an anchor rod and an anchor cylinder sleeved on the anchor rod, and the two are connected by threads;

[0013] The first reinforcement mechanism includes a reinforcement plate hinged at one end to the anchor cylinder and a support assembly disposed on the anchor rod, the support assembly being used to support the reinforcement plate after it is deployed.

[0014] Furthermore, the support assembly includes a drive disc that is slidably sleeved on the anchor rod and located below the anchor cylinder, and the drive disc is connected to the reinforcing plate via a support rod.

[0015] Furthermore, it also includes a second reinforcement mechanism, which includes a mounting base disposed within the anchor bolt and a reverse hook rod slidably disposed on the mounting base; the reverse hook rod is connected to a drive assembly for driving it to extend and retract radially along the anchor bolt.

[0016] Furthermore, the drive assembly includes a rotating shaft located within the anchor bolt, one end of which is connected to the anti-hook rod via gear transmission, and the other end extending to the top of the anchor bolt.

[0017] Furthermore, the anti-hook rod is provided in two sets, and is arranged in a mirror-symmetrical manner.

[0018] Furthermore, the reinforcing plate is provided with a buffer mechanism, which includes a support platform and an arc-shaped buffer plate disposed on the support platform.

[0019] Furthermore, a buffer assembly is provided in the area enclosed between the buffer plate and the support platform. The buffer assembly includes a beam rod and a beam seat disposed on the support platform. One end of the beam rod extends into the beam seat and is connected to a damping spring, and the other end is connected to the bottom of the buffer plate through a beam plate.

[0020] Furthermore, the support platform is arranged parallel to the reinforcing plate above it via connecting rods.

[0023] Drive the tightened protective device into the hole in the predetermined direction and depth;

[0024] Rotate the control panel, which drives the anchor bolt to rotate. The anchor bolt moves downward through the thread inside the anchor tube, pushing the anchor head deeper into the interior. At the same time, the reinforcing plate rotates under force and finally unfolds. At this time, the support rod supports the unfolded reinforcing plate from the bottom.

[0025] Next, the rotating shaft is rotated, and the gear transmission drives the anti-hook rod to extend and enter and exit the rock and soil on both sides.

[0026] 3. Beneficial effects

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) The high slope protection device of the present invention utilizes the anchoring effect of the anchor to effectively improve the strength and stability of the rock and soil itself; in addition, as the anchor rod continues to penetrate, it drives the reinforcement plate to unfold, and after unfolding, it is locked with the rock and soil, which can further improve the stability of the rock and soil to prevent it from loosening or even sliding, thereby effectively reducing the risk of slope structure collapse.

[0029] (2) A high slope protection device of the present invention, through the setting of the second reinforcement mechanism, the rotating shaft can be rotated to insert the anti-hook rod into the rock and soil, and the anti-hook rod hooks into the layered rock mass in the opposite direction so that the anti-ditch rod is tightly combined with the rock layer, which can further enhance the stability of the rock and soil.

[0030] (3) A high slope protection device of the present invention, through the setting of a buffer mechanism, when the rock blocks slide down, the impact force of the rock blocks falling can be effectively buffered by the buffer plate and buffer components, thereby ensuring the stability of the protection device.

[0042] The present invention will be further described below with reference to specific embodiments.

[0043] Example 1

[0044] like Figure 1 , Figure 2 As shown, a high slope protection device according to this embodiment includes an anchor 1 and a first reinforcement mechanism 2.

[0045] The anchor 1 includes an anchor rod 11 and an anchor cylinder 12 sleeved on the anchor rod 11. The bottom of the anchor rod 11 is provided with an anchor head 13, and the top of the anchor rod 11 is provided with an operating disc 14.

[0046] The anchor cylinder 12 and the anchor rod 11 are connected by threads. Thus, when the operating disc 14 is rotated, the operating disc 14 drives the anchor rod 11 to rotate, and the anchor rod 11 moves downward inside the anchor cylinder 12 through the threads, thereby entering the rock and soil.

[0047] The first reinforcement mechanism 2 includes a reinforcement plate 21 hinged at one end to the anchor cylinder 12, and a support assembly disposed on the anchor rod 11, which is used to support the reinforcement plate 21 after it is unfolded.

[0048] Specifically, in this embodiment, the support assembly includes a drive disc 22 and a support rod 23. The drive disc 22 is slidably sleeved on the anchor rod 11 and located below the anchor cylinder 12.

[0049] The reinforcing plates 21 are arranged in two sets symmetrically around the center line of the anchor rods 11. One end of the support rod 23 is hinged to the drive disc 22, and the other end is hinged to the reinforcing plate 21, thereby realizing the linkage between the three.

[0050] This embodiment of a high slope protection device firstly utilizes the anchoring effect of the anchor 1 itself to effectively improve the strength and stability of the rock and soil; in addition, by using the unfolded reinforcing plate 21 to clamp the rock and soil together, the stability of the rock and soil can be further improved to prevent it from loosening, thereby effectively reducing the risk of slope structure collapse.

[0051] Example 2

[0052] To further improve the anchoring effect of the protective device and ensure the stability of the soil and rock, this embodiment of a high slope protection device, based on embodiment 1, also includes a second reinforcement mechanism 3.

[0053] refer to Figure 1 , Figure 3 As shown, the second reinforcement mechanism 3 includes a mounting base 31, a hook rod 32, and a drive assembly.

[0054] The mounting base 31 is disposed inside the anchor rod 11, and the mounting base 31 is provided with a sliding groove for the anti-hook rod 32 to slide.

[0055] The drive assembly is used to drive the anti-hook rod 32 to move telescopically within the groove. Of course, the anchor rod 11 has a through hole through which the anti-hook rod 32 passes.

[0056] Specifically, in this embodiment, the anti-hook rod 32 is provided in two sets, and is arranged in a mirror-symmetrical manner.

[0057] The drive component is a rotating shaft 33, which is located inside the anchor rod 11. One end of the rotating shaft 33 is provided with a gear that meshes with the tooth groove on the anti-hook rod 32, and the other end extends to the operating disc 14 at the top of the anchor rod 11.

[0058] Preferably, the operating disc 14 and the anchor rod 11 are detachably connected, thereby facilitating the rotation operation of the rotating shaft 33 inside the anchor rod 11.

[0059] In this embodiment of a high slope protection device, by setting up a second reinforcement mechanism 3, rotating the rotating shaft 33 can drive the anti-hook rod 32 to move outward and insert into the rock and soil. The anti-hook rod 32 hooks into the layered rock mass in the opposite direction, so that the anti-hook rod is tightly combined with the rock layer, thereby further enhancing the stability of the rock and soil.

[0060] Example 3

[0061] Because of the high slope, rocks frequently slide down. When rocks fall onto the protective device, they exert a certain impact force, thus affecting the stability of the soil and rock within the protected area.

[0062] Therefore, in this embodiment of a high slope protection device, a buffer mechanism 4 is provided on the reinforcing plate 21.

[0063] refer to Figure 1 , Figure 4 As shown, the buffer mechanism 4 includes a support platform 41, which is mounted above the reinforcing plate 21 via a connecting rod 47 at its bottom and is arranged parallel to the reinforcing plate 21.

[0064] The top of the support platform 41 is provided with a buffer plate 42, which is used to effectively buffer the impact force of falling rocks, thereby ensuring the stability of the soil and rock in the area.

[0065] Specifically, in this embodiment, the buffer plate 42 is arc-shaped, and multiple arc-shaped buffer plates 42 are provided along the length direction of the support platform 41.

[0066] This embodiment of a high slope protection device utilizes the elasticity of the buffer plate 42 itself to effectively offset the impact force of rocks on the reinforcement plate 21.

[0067] Example 4

[0068] To further reduce the impact of falling rocks on the protective device, a buffer assembly is also provided in the area enclosed between the buffer plate 42 and the support platform 41.

[0069] refer to Figure 5 , Figure 6 As shown, the buffer assembly includes a beam rod 43, a beam seat 44, a beam plate 46, and a damping spring 45.

[0070] The beam seat 44 is mounted on the support platform 41, and the damping spring 45 is mounted inside the beam seat 44.

[0071] One end of the beam rod 43 extends into the beam seat 44 and is connected to the damping spring 45, and the other end is connected to the beam plate 46; the beam plate 46 is located below the buffer plate 42.

[0072] The construction method of a high slope protection device according to this embodiment is as follows:

[0073] First, holes need to be drilled on the high slope surface;

[0074] Drive the tightened protective device into the hole in the predetermined direction and depth;

[0075] Rotate the operating disc 14, which drives the anchor rod 11 to rotate. The anchor rod 11 moves downward through the thread inside the anchor tube 12, pushing the anchor head 13 deeper into the interior for anchoring.

[0076] As the anchor head 13 penetrates deeper, the reinforcing plate 21 rotates under force and eventually unfolds, clamping itself tightly with the soil and rock to improve the stability of the soil and rock; at this time, the support rod 23 supports the unfolded reinforcing plate 21 from the bottom.

[0077] Next, rotate the rotating shaft 33, and drive the anti-hook rod 32 to extend and insert into the rock and soil on both sides through gear transmission. The anti-hook rod 32 hooks into the layered rock mass in the opposite direction, so that the anti-ditch rod is tightly combined with the rock layer, which can further enhance the stability of the rock and soil.

[0078] As the reinforcing plate 21 unfolds, the buffer mechanism 4 unfolds as well, positioning it above the reinforcing plate 21. When a rock falls onto the buffer plate 42, the buffer plate 42 itself can offset part of the impact force, and part of the impact is transmitted to the beam plate 46. The beam plate 46 drives the beam rod 43 to compress the damping spring 45. Through the reverse force of the damping spring 45, the impact force on the beam plate 46 can be effectively dispersed, thereby reducing the interference of the rockfall impact force on the surrounding rock of the protected area.

[0079] Example 5

[0080] This embodiment is another implementation of the second reinforcement mechanism 3.

[0081] refer to Figure 7 As shown, the second reinforcement mechanism 3 includes a mounting base 31, a hook rod 32, and a rotating shaft 33.

[0082] The mounting base 31 is disposed on the outer peripheral wall of the anchor rod 11, and two mounting bases 31 are connected by a rotating shaft 33. The end of the anti-hook rod 32 is rotatably sleeved on the rotating shaft 33.

[0083] Preferably, the side of the anti-hook rod 32 facing the anchor rod 11 is a plane, and the side away from the anchor rod 11 is a tapered arc surface.

[0084] In this embodiment of a high slope protection device, when the rock and soil become loose, the anti-hook rod 32 can hook the rock layer from the inside to ensure the stability of the rock and soil in the protected area.

[0085] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
