Description

Technical Field

[0001] This utility model relates to the technical field of anchoring structures, specifically a prefabricated anchoring structure for slope support. Background Technology

[0002] In engineering, a type of tension member is often embedded in the rock and soil mass to mobilize and improve the strength and self-stabilizing ability of the rock and soil mass. This type of tension member is called an anchor or anchor cable, and its function is anchoring. The anchor used in slope protection engineering is a type of tension member installed deep in the rock and soil layer.

[0003] Utility model patent CN219430792U discloses a prefabricated anchoring structure for slope support, belonging to the technical field of anchoring structures. It addresses the problem in existing technologies where prefabricated structures, with their predetermined geometric relationships between anchors, slope surfaces, and anchor rods, cannot meet construction requirements due to varying angles between different slope locations and the horizontal plane during actual construction. In some areas, the anchor rod angle needs to be determined based on the actual angle. The proposed anchoring structure includes a support plate with a fixed cylinder on one side and a fixing component on the other. A prefabricated anchor is movably installed inside the fixed cylinder, and an anchor rod is installed inside the prefabricated anchor. An anchor rod hole is formed on the surface of the support plate, through which the anchor rod passes. An adjustment component, including two swing plates, is located on the outside of the prefabricated anchor. The swing plates have perforations on their surfaces, and a limiting component passing through these perforations is located on one side of the support plate. This utility model allows for easy adjustment of the anchor head angle, enabling the installation of anchor rods at specific angles based on the actual working conditions of the slope angle, thereby ensuring the stability of the slope support while meeting construction requirements.

[0004] However, the above patents still have shortcomings: when assembling the anchors of this patent, it is generally necessary to first pour concrete into the inside of the slope, then insert the bolt into the inside of the poured concrete, and only after the concrete has solidified the bolt inside the slope can the assembly of the anchor be completed. This not only makes the assembly process of the anchor more complicated, but also requires a lot of time for the concrete to solidify, which in turn makes the assembly speed of the anchor slower and the work efficiency lower. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prefabricated anchoring structure for slope support, which solves the problem mentioned in the background art that the existing prefabricated anchoring structures for slope support generally require pouring concrete into the interior of the slope first, then inserting the bolt into the poured concrete, and only after the concrete has solidified the bolt inside the slope can the anchor assembly be completed. This not only makes the anchor assembly process complicated, but also requires a lot of time for the concrete to solidify, resulting in a slow assembly speed and low work efficiency.

[0006] The technical solution of this utility model is:

[0007] A prefabricated anchoring structure for slope protection includes: a slope body; an anchoring groove is provided inside the slope body, and a matching anchor bolt body is provided inside the anchoring groove; a fixing plate is fixedly connected to one end of the anchor bolt body, and a locking sleeve is fixedly connected to the side of the fixing plate away from the anchor bolt body; an elastic mechanism is provided inside the anchor bolt body to simplify the assembly and disassembly process of the anchor bolt body; and a locking mechanism is provided inside the locking sleeve to improve the stability of the anchor bolt body after assembly.

It solves the problem that existing prefabricated anchor structures for slope support typically require pouring concrete into the slope first, then inserting the bolt into the poured concrete, and waiting for the concrete to solidify the bolt inside the slope before the anchor bolt assembly can be completed.

[0024] 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.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] An assembled anchoring structure for slope protection includes: a slope body 1; an anchoring groove 2 is provided inside the slope body 1, and a matching anchor bolt body 3 is provided inside the anchoring groove 2; a fixing plate 4 is fixedly connected to one end of the anchor bolt body 3, and a locking sleeve 5 is fixedly connected to the side of the fixing plate 4 away from the anchor bolt body 3; an elastic mechanism 6 is provided inside the anchor bolt body 3 to simplify the assembly and disassembly process; and a locking mechanism 7 is provided inside the locking sleeve 5 to improve the stability of the anchor bolt body 3 after assembly. The user inserts the anchor bolt body 3 into the anchoring groove 2 inside the slope body 1, and then fixes the anchor bolt body 3 inside the anchoring groove 2 of the slope body 1 by the elastic mechanism 6, thus completing the assembly of the anchor bolt body 3.

[0027] like Figure 2 and Figure 3 As shown, the elastic mechanism 6 includes: a sliding column 8 adapted to the anchor bolt body 3 is provided inside; three first movable grooves 9 are evenly provided on the outer surface of the sliding column 8; four first steel balls 10 are provided near the first movable grooves 9 on the anchor bolt body 3; a first ball groove 11 adapted to the anchor bolt body 3 is provided near the first steel balls 10; a retaining groove 12 is provided near the first steel balls 10 on the slope body 1; the first movable grooves 9 and retaining grooves 12 are adapted to the first steel balls 10; a pressing rod 13 is fixedly connected to one end of the sliding column 8 near the fixed plate 4; the end of the pressing rod 13 away from the sliding column 8 passes through the fixed plate 4 and the locking sleeve 5 and extends to the pressing plate 14; the pressing plate 14 is fixedly connected to the pressing rod 13; the user pushes the pressing rod 13 through the pressing plate 14. Pressing rod 13 drives sliding column 8, causing sliding column 8 to slide downward inside anchor bolt body 3. While sliding column 8 slides towards the bottom of anchor bolt body 3, it drives first movable groove 9, causing first movable groove 9 to move to first ball groove 11, increasing the range of motion of first steel ball 10. Then, after anchor bolt body 3 is inserted into the anchoring groove 2 inside slope body 1, pressing plate 14 is released, sliding column 8 is reset, and then slides towards the top of anchor bolt body 3. While sliding column 8 slides towards the top of anchor bolt body 3, it drives first movable groove 9, causing first movable groove 9 to separate from first ball groove 11. At the same time, sliding column 8 squeezes and pushes first steel ball 10, causing a small part of first steel ball 10 to move into slot 12, thus completing the assembly of anchor bolt body 3.

[0028] like Figure 2 As shown, a first spring 15 is provided at the end of the sliding column 8 away from the pressing rod 13. The first spring 15 is located inside the anchor bolt body 3. When the user releases the pressing plate 14, the first spring 15 will elastically recover and push the sliding column 8 to slide back to the top of the anchor bolt body 3.

[0029] like Figure 4 and Figure 5As shown, the locking mechanism 7 includes: six second ball grooves 16 evenly distributed inside the locking sleeve 5, each containing a second steel ball 17; a compression ring 18 slidably connected to the locking sleeve 5 near the second steel ball 17; a connecting ring 19 fixedly connected to the outer surface of the compression ring 18; a force-applying ring 20 fixedly connected to the outer surface of the connecting ring 19; a second spring 21 located inside the locking sleeve 5 near the end of the compression ring 18 near the fixing plate 4; a second movable groove 22 on the inner wall of the compression ring 18; and a locking groove 23 near the second steel ball 17 on the pressing rod 13. Both the second movable groove 22 and the locking groove 23 are adapted to the second steel ball 17. When the user pulls the force-applying ring 20... 0. The force-applying ring 20 drives the connecting ring 19, which in turn drives the compression ring 18. This causes the second movable groove 22 on the compression ring 18 to move to the second ball groove 16, increasing the range of motion of the second steel ball 17. This allows the pressing rod 13 to slide inside the locking sleeve 5. After the anchor bolt body 3 is assembled inside the slope body 1, the user releases the force-applying ring 20. The second spring 21 elastically recovers and pushes the compression ring 18, causing it to reset. As the compression ring 18 resets, it causes the second movable groove 22 to separate from the second ball groove 16 and compresses the second steel ball 17. This causes a small portion of the second steel ball 17 to enter the locking groove 23 on the surface of the pressing rod 13, thus locking and fixing the pressing rod 13 and preventing it from sliding.

[0030] like Figure 4 As shown, the locking sleeve 5 has a travel groove 24 near the connecting ring 19. The travel groove 24 cooperates with the compression ring 18 to limit the movement of the compression ring 18.

[0031] like Figure 4 As shown, a damping pad 25 is provided on the outer surface of the force ring 20. The damping pad 25 is fixedly connected to the force ring 20, which makes it convenient for the user to pull the force ring 20 through the damping pad 25, and avoids the user's hand from slipping at the contact point with the force ring 20.

[0032] like Figure 1 and Figure 2As shown, a grid beam 26 is provided between the slope body 1 and the fixing plate 4. A retaining wall 27 is fixedly connected to the bottom end of the grid beam 26. A stop block 28 is fixedly connected to the side of the retaining wall 27 away from the grid beam 26. A drainage groove 29 is provided on the top of the stop block 28. A drainage hole 30 is provided inside the retaining wall 27. The drainage hole 30 cooperates with the drainage groove 29. The grid beam 26 is provided with matching installation holes 31 near the anchor bolt body 3. The user fixes the grid beam 26 to the surface of the slope body 1 by cooperating with multiple anchor bolt bodies 3. Rainwater flows through the inclined surface of the grid beam 26 to the space between the grid beam 26 and the retaining wall 27, and then flows into the drainage groove 29 inside the stop block 28 through the drainage hole 30 inside the retaining wall 27, thus achieving the function of drainage.

[0033] Working principle: The user pushes the pressing rod 13 by pressing the pressing plate 14. The pressing rod 13 drives the sliding column 8, causing the sliding column 8 to slide downward inside the anchor bolt body 3. As the sliding column 8 slides towards the bottom of the anchor bolt body 3, it drives the first movable groove 9, causing the first movable groove 9 to move to the first ball groove 11, increasing the range of motion of the first steel ball 10. Then, after the anchor bolt body 3 is inserted into the anchoring groove 2 inside the slope body 1, the pressing plate 14 is released. The first spring 15 pushes the sliding column 8 to reset, and then slides towards the top of the anchor bolt body 3. As the sliding column 8 slides towards the top of the anchor bolt body 3, it drives the first movable groove 9, causing the first movable groove 9 to separate from the first ball groove 11. At the same time, the sliding column 8 squeezes and pushes... The first steel ball 10 is moved, causing a small portion of it to move into the slot 12, thereby completing the assembly of the anchor bolt body 3. This not only simplifies the anchor bolt assembly process but also reduces the time required for assembly, thus improving the efficiency of anchor bolt assembly. This solves the problem that existing prefabricated anchoring structures used for slope support typically require pouring concrete into the slope first, then inserting the bolt into the concrete, and waiting for the concrete to solidify the bolt before assembly can be completed. This not only makes the assembly process complex but also requires a significant amount of time for concrete to solidify, resulting in slow assembly speed and low efficiency.

[0034] When the user pulls the force ring 20, the force ring 20 drives the connecting ring 19, which in turn drives the compression ring 18. This causes the second movable groove 22 on the compression ring 18 to move to the second ball groove 16, increasing the range of motion of the second steel ball 17. This allows the pressing rod 13 to slide inside the locking sleeve 5. After the anchor bolt body 3 is assembled inside the slope body 1, the user releases the force ring 20. The second spring 21 elastically recovers and pushes the compression ring 18, causing it to reset. As the compression ring 18 resets, it causes the second movable groove 22 to separate from the second ball groove 16 and compresses the second steel ball 17. A small portion of the second steel ball 17 enters the locking groove 23 on the surface of the pressing rod 13, thus locking and fixing the pressing rod 13. This prevents the pressing rod 13 from sliding and extends, locking the anchor bolt assembled inside the slope and preventing it from separating from the slope. This improves the stability of the anchor bolt after assembly and enhances its practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
