Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slope support anchor reinforcement combination device, specifically a slope support anchor reinforcement combination device for geological disaster control. Background Technology
[0002] Anchor bolt support is a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chamber construction such as tunnels and mining areas. It uses metal, wood, polymer or other materials to make rods, which are driven into pre-drilled holes in the surface rock or the rock mass surrounding the chamber. By utilizing the special structure of the head and body of the rod and the tail plate, or by relying on the bonding effect, the surrounding rock is combined with the stable rock mass to produce a suspension effect, composite beam effect, and reinforcement effect to achieve the purpose of support. Utility model patent CN221645791U discloses a combined device for reinforcing slope support with anchor rods in geological disaster control. The device includes a slope earthwork, a steel mesh on top of the earthwork, a fixing part above the steel mesh, and an anchoring part below the fixing part. The anchoring part includes an insert rod, the surface of which is inserted into the slope earthwork. A support rod is provided on the inner wall of the insert rod, and the outer side of the support rod is fixedly connected to the inner wall of the insert rod. A limiting ring is provided on the inner side of the support rod, and the outer side of the limiting ring is fixedly connected to the inner side of the support rod. A segment is provided on the surface of the insert rod, and the inner wall of the segment is fixedly connected to the surface of the insert rod. The above-mentioned technical solution involves drilling the insertion rod into the slope soil, simultaneously inserting the segment and plug into the slope soil, inserting the push rod into the insertion rod, and then pushing the fixing rod into the slope soil for anchoring. This setup can improve the anchoring strength and stability of the device. However, this solution is difficult to drill into harder soil, and since it relies solely on the insertion rod to compress the plug for fixation, its pull-out resistance is poor, posing a risk of anchoring failure. Furthermore, the adjacent anchoring structures are not easily connected and coordinated, thus failing to increase the stability of the anchoring on variable slopes. Utility Model Content
[0003] The purpose of this utility model is to provide a combined device for reinforcing slope support anchors in geological disaster management, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A combination device for reinforcing slope support with anchor bolts in geological disaster control includes a drill bit, an expansion component above the drill bit, and a connecting component above the expansion component. The expansion component includes a shell, a long rod inside the shell, and three sets of expansion plates coaxially and equally spaced on the outer side of the long rod. Each set of expansion plates has three pieces and is distributed in a ring at equal intervals. The shell has grooves corresponding to the expansion plates. A disc is fitted on the right end of the shell, and a retaining ring is provided on the right side of the disc. The connecting assembly includes a connecting plate and a connecting ring on the left side of the connecting plate. The connecting plate has holes at equal intervals, and connecting bolts are provided at the corresponding positions of the holes. The upper and lower ends of the right side of the connecting plate are provided with first locking blocks, and the front and rear ends of the right side of the connecting plate are provided with second locking blocks.

[0006] In this invention, the drill bit is welded and fixed to the outer shell to form a solid whole. One end of the expansion plate is rotatably connected to the outer shell to achieve opening and closing. After the anchor rod enters the predetermined position, the expansion plate unfolds as needed to increase the contact area and friction between the anchor rod and the surrounding soil. The connecting rod is fixed on the circular plate, and the column block drives the connecting rod to move. The connecting rod is rotatably connected to the expansion plate, so that the expansion plate rotates around the connection point of the outer shell to realize the unfolding of the expansion plate.
[0007] Preferably, the connecting rod has a three-groove plate on its right side, the three-groove plate has three slots that mate with the column block, the long rod is bonded and fixed to the three-groove plate, and the long rod is rotatably connected to the circular piece, and a limiting strip is provided at the point where the circular piece and the connecting rod fit together.
[0008] In this invention, the three grooved discs cooperate with the column block. When the long rod rotates, it will drive the three grooved discs to move synchronously. The movement of the three grooved discs causes the grooves to exert a force on the column block, which pushes the connecting rod to move. The connecting rod is rotatably connected to the expansion plate, realizing the expansion plate's unfolding or contraction. The limiting strip limits the direction of movement of the connecting rod.
[0009] Preferably, a fixing block is provided on the right side of the inner side of the outer shell. The fixing block is bonded and fixed to the inner wall of the outer shell. A round hole is opened in the middle of the fixing block, and a long rod passes through the round hole. A nut is fitted on the outer ring of the long rod on the right side of the fixing block, and the nut is threadedly connected to the long rod.
[0010] In this invention, the circular hole in the middle of the fixing block provides precise positioning and guidance for the long rod, preventing the long rod from shifting or shaking during use. A nut is used to fix the long rod, thereby fixing the expansion plate when it unfolds.
[0011] Preferably, the disk has a plurality of screw holes that are evenly spaced, and the disk is rotatably connected to the outer shell.
[0012] In this invention, the disc can rotate relative to the outer shell. During installation, the position of the screw holes can be adjusted for easy installation and use. The equally spaced screw holes make the connection more uniform and stable.

[0014] In this invention, the inner diameter of the connecting ring is adapted to the outer diameter of the outer shell, the connecting ring is sleeved on the right end of the outer shell, and the connecting bolt passes through the hole and connects with the screw hole, thereby increasing the overall structural stability.

[0016] In this utility model, the first and second locking blocks facilitate the installation and connection of the steel bars, and the grooves can be used in conjunction with the first locking blocks to securely install the steel bars. Furthermore, the vertical and horizontal steel bars are installed in a staggered manner.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The drill bit of this utility model is welded and fixed to the outer shell. The drill bit is spiral-shaped, which can more effectively break the soil. Different drill bits can be adapted to different geological conditions. The rotation of the long rod drives the three grooved discs to move synchronously. The three grooved discs push the column block through the groove holes, which in turn drives the connecting rod to move. Finally, the expansion plate rotates around the rotation point of the outer shell, realizing the expansion plate unfolding. After the expansion plate unfolds, the contact area with the surrounding soil increases, and one end of the expansion plate is embedded in the soil, which increases the friction between the expansion plate and the soil, making the anchor more stable in the soil and improving the pull-out resistance. 2. The disc of this utility model can be rotated to adjust the position of the screw hole, which facilitates the installation with the connecting components. The first and second locking blocks are fixedly connected by fastening bolts, which facilitates installation and disassembly.

[0020] 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.
[0021] Please see Figures 1-6 This embodiment provides a technical solution: A combination device for reinforcing slope support anchors in geological disaster control includes a drill bit 1, an expansion component 2 above the drill bit 1, and a connecting component 3 above the expansion component 2. The connecting component 3 includes a connecting plate 31 and a connecting ring 36 on the left side of the connecting plate 31.

The connecting ring 36 is welded and fixed to the connecting plate 31. The connecting plate 31 has holes corresponding to the screw holes, and the corresponding connecting bolts 32 are provided in the holes. The connecting bolts 32 pass through the connecting plate 31 and are threadedly connected to the screw holes.
[0022] In this utility model, the inner diameter of the connecting ring 36 is adapted to the outer diameter of the outer shell 21, the connecting ring 36 is sleeved on the right end of the outer shell 21, and the connecting bolt 32 passes through the hole and connects with the screw hole, thereby increasing the overall structural stability.
[0023] Furthermore, the first locking block 33 and the second locking block 35 are fixed to the connecting plate 31 by fastening bolts. The connecting plate 31 is provided with a groove 34 perpendicular to the first locking block 33, and the steel bar can be inserted and fixed into the groove 34.

[0025] The expansion assembly 2 includes a housing 21. Inside the housing 21, there is a long rod 25. Three sets of expansion plates 22 are coaxially and equally spaced on the outside of the long rod 25. Each set of expansion plates 22 has three pieces and is distributed in a ring at equal intervals. The housing 21 has grooves corresponding to the expansion plates 22. A disc 23 is fitted on the right end of the housing 21. A retaining ring 27 is provided on the right side of the disc 23. The drill bit 1 is welded and fixed to the housing 21. The left end of the expansion plate 22 is rotatably connected to the housing 21. A circular piece 221 is provided on the inner side of the expansion plate 22. Three connecting rods 223 are provided on the right side of the circular piece 221 and are distributed in a ring at equal intervals. Each end of the connecting rod 223 is provided with a column block 224. The connecting rod 223 is rotatably connected to the expansion plate 22.
[0026] In this utility model, the drill bit 1 is welded and fixed to the outer shell 21 to form a solid whole. One end of the expansion plate 22 is rotatably connected to the outer shell 21 to realize opening and closing. After the anchor rod enters the predetermined position, the expansion plate 22 unfolds as needed to increase the contact area and friction between the anchor rod and the surrounding soil. The connecting rod 223 is fixed on the circular plate 221. The column block 224 drives the connecting rod 223 to move. The connecting rod 223 is rotatably connected to the expansion plate 22, so that the expansion plate 22 rotates around the connection point of the outer shell 21 to realize the unfolding of the expansion plate 22.
[0027] Specifically, the right side of the connecting rod 223 is provided with a three-groove plate 222, which has three slots that cooperate with the column block 224. The long rod 25 is bonded and fixed to the three-groove plate 222, and the long rod 25 is rotatably connected to the circular piece 221. A limiting strip 225 is provided at the contact point between the circular piece 221 and the connecting rod 223.
[0028] In this utility model, the three-groove disk 222 cooperates with the column block 224. When the long rod 25 rotates, it will drive the three-groove disk 222 to move synchronously. The movement of the three-groove disk 222 causes the groove holes to exert a force on the column block 224, pushing the connecting rod 223 to move. The connecting rod 223 is rotatably connected to the expansion plate 22, realizing the expansion plate 22's unfolding or contraction. The limiting strip 225 limits the movement direction of the connecting rod 223.
[0029] In addition, a fixing block 24 is provided on the right side of the inner side of the outer casing 21. The fixing block 24 is bonded and fixed to the inner wall of the outer casing 21. A round hole is opened in the middle of the fixing block 24, and the long rod 25 passes through the round hole. A nut 26 is fitted on the outer ring of the long rod 25 on the right side of the fixing block 24. The nut 26 is threadedly connected to the long rod 25.
[0030] In this utility model, the round hole in the middle of the fixing block 24 provides precise positioning and guidance for the long rod 25, preventing the long rod 25 from shifting or shaking during use. The nut 26 is set to fix the long rod 25, thereby fixing the expansion plate 22 when it unfolds.
[0031] The disc 23 has several screw holes that are evenly spaced, and the disc 23 is rotatably connected to the outer shell 21.
[0032] In this invention, the disc 23 can rotate relative to the outer shell 21. During installation, the position of the screw holes can be adjusted to facilitate installation and use. The equally spaced screw holes make the connection more uniform and stable.
[0033] In this embodiment, the geological disaster control slope support anchor reinforcement combination device is used by welding and fixing the drill bit 1 to the outer shell 21, and then installing the circular plate 221 and the connecting rod 223 with the column block 224 and the three-groove plate 222 inside the outer shell 21. A long rod 25 is provided at the center of the outer shell 21. The long rod 25 is welded and fixed to the three-groove plate 222 and rotatably connected to the circular plate 221. A fixing block 24 is sleeved on the right end of the long rod 25, and the fixing block 24 is welded and fixed to the inner wall of the outer shell 21. A nut 26 is provided on the outer ring of the long rod 25 on the right side of the fixing block 24. A disc 23 and a retaining ring 27 are sleeved on the right end of the outer shell 21.
[0034] After installation, the right end of the outer casing 21 has a round hole. The connector of the external portable electric drill is inserted into the right end of the outer casing 21, and the corresponding positioning bolt passes through the round hole and is fixedly connected to the connector of the electric drill. Turn on the control switch of the portable electric drill, and the drill bit 1 rotates and drills into the required position. After drilling, remove the positioning bolt and the portable electric drill. The portable electric drill is powered by an external lithium battery. The external screwdriver is inserted into the Phillips head slot at the end of the rotating rod 25. The screwdriver's rotation causes the rotating rod 25 to rotate, which in turn causes the three-groove disc 222 to move synchronously. The grooves in the three-groove disc 222 push the column block 224, which in turn moves the connecting rod 223. Ultimately, this causes the expansion plate 22 to rotate around the rotation point of the outer shell 21, thus unfolding the expansion plate 22. After unfolding, the contact area between the expansion plate 22 and the surrounding soil increases, and one end of the expansion plate 22 is embedded in the soil, increasing the friction between the expansion plate 22 and the soil, thus strengthening the anchor rod in the soil. The process is more stable and effectively improves the pull-out resistance. After the fixation is completed, tighten the nut 26 to fix the long rod 25. Then, align the outer wall of the connecting ring 36 with the inner wall of the outer shell 21. Rotate the disc 23 to align the screw hole of the disc 23 with the hole of the connecting plate 31 on the same axis. Then, pass the connecting bolt 32 through the hole and connect and fix it with the screw hole. Finally, connect multiple anchor rods with the steel bar through the cooperation of the first clamping block 33, the second clamping block 35 and the groove 34 to achieve the combination and fixation between two adjacent outer shells 21, thereby achieving the constraint and reinforcement of the soil.
