Description

Technical Field

[0001] This utility model is a slope protection buffer energy dissipation device, belonging to the field of slope protection technology. Background Technology

[0002] Slope protection and buffering energy dissipation refers to the use of various technologies and devices in slope protection engineering to absorb and dissipate the kinetic energy of rocks, soil, and other objects that may roll down the slope, in order to protect people, buildings, roads, and other structures below from impact damage.

[0003] Wire mesh is fixed to the slope surface using a combination of anchor bolts and anchor plates to cover the slope and prevent the stripping of soil and rock and the falling of small rocks. The wire mesh has deformable properties, thus also serving as a buffer and energy dissipation mechanism. Because the area where the wire mesh is held down by the anchor plates is fixed relative to the slope, there is a possibility that the area where the wire mesh is held down by the anchor plates may be damaged due to tension. In this case, a layer of wire mesh needs to be laid on the damaged area and the two layers of wire mesh need to be connected. Since the tensile strength of the connection area between the two layers of wire mesh is relatively high, anchor bolts need to be installed in the connection area. Then, anchor plates are installed on the installed anchor bolts using nuts to reinforce the connection area between the two layers of wire mesh. This method has the disadvantage of a large workload due to the installation of anchor bolts, which affects the construction efficiency of the mesh replacement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slope protection buffer energy dissipation device to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope protection, buffer, and energy dissipation device, comprising an anchor rod, one end of which is fitted with a threaded head. A slope protection wire mesh is fitted onto the anchor rod, and an anchor plate is provided on the side of the slope protection wire mesh near the threaded head. The anchor plate is fitted onto the anchor rod, and a nut is threaded onto the threaded head for pressing the slope protection wire mesh and the anchor plate onto the slope surface. A straight threaded cylinder is installed on the side of the nut facing away from the anchor plate, and a repair iron is fitted onto the straight threaded cylinder. The wire mesh includes a stud internally threaded cylinder. A column is mounted on one end of the stud outside the screw cylinder. Both ends of the column are fitted with limiting rings that are fixed to the column. Multiple contacting rings are provided between the two limiting rings. The rings are fitted onto the column and can rotate around the column. A support arm is fixedly connected to the outer surface of the ring. A screw is threaded onto the support arm. A detachable pressure plate is installed at one end of the screw for pressing and holding the connection between the slope protection wire mesh and the repair wire mesh.

[0006] Specifically, a plug for sealing the open end of the straight threaded cylinder is slidably installed inside the straight threaded cylinder, and a positioning plate is installed inside the straight threaded cylinder near the nut. The positioning plate has a circular structure, and a spring is installed between the positioning plate and the plug. The spring is arranged along the length of the straight threaded cylinder.

[0007] Specifically, the side of the plug facing the positioning piece is recessed to form a blind hole, and the side of the spring away from the positioning piece is installed in the blind hole.

[0008] Specifically, a rubber sheet is glued to the side of the plug that is away from the positioning piece. The rubber sheet has a circular structure, the diameter of the plug is smaller than the diameter of the rubber sheet, and the diameter of the rubber sheet is the same as the inner diameter of the straight threaded cylinder.

[0009] Specifically, a hexahedron for engaging the wrench is installed at the center of the side of the column away from the stud, and the hexahedron and the column are integrally formed.

[0010] Specifically, one side of the support arm plate has a plurality of first screw holes, which are arranged along the length of the support arm plate. The screw is threaded into the first screw holes, and a handle is installed on the outer surface of the end of the screw away from the pressure plate.

[0011] Specifically, a threaded sleeve is installed at the center of the side of the pressure plate facing the screw, and the end of the screw near the pressure plate is threaded into the threaded sleeve.

[0012] Specifically, three second screw holes are equidistantly arranged in a ring at one edge of the pressure plate. Long bolts are threaded into the second screw holes, and a knob head is installed at one end of the long bolt. The knob head and the bolt are integrally formed.

[0013] Specifically, the threaded head and the anchor rod are integrally formed, and the outer surface of the anchor rod is uniformly machined with multiple protrusions, which are integrally formed with the anchor rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. Cover the area of ​​the slope protection wire mesh near the anchor plate with repair wire mesh and connect the repair wire mesh to the slope protection wire mesh. Then screw the stud into the straight threaded cylinder to complete the assembly of the column and the anchor rod. Make multiple rings rotate around the column and stagger the multiple support plates. Then screw the screw on the support plate so that the pressure plate at one end of the screw presses against the connection between the repair wire mesh and the slope protection wire mesh. This strengthens the connection between the slope protection wire mesh and the repair wire mesh, eliminating the need to install new anchor rods at the connection between the slope protection wire mesh and the repair wire mesh, reducing the workload of slope protection wire mesh repair and improving the work efficiency of slope protection wire mesh repair.

[0016] 2. Supported by the spring, the plug is positioned at the open end of the straight threaded cylinder. The plug then provides real-time sealing of the open end, preventing foreign matter from entering the cylinder and affecting the assembly of the stud and the cylinder. When the stud is screwed into the cylinder, it compresses the plug, which in turn compresses the spring, causing elastic deformation. The spring's rebound force prevents relative rotation between the stud and the cylinder, thus preventing loosening. When the distance between the plug and the positioning plate decreases, the spring is positioned within a blind hole, preventing excessive compression and damage. Installing a rubber sheet on the plug further enhances the sealing effect on the open end of the straight threaded cylinder by utilizing its deformable properties.

[0017] 3. After using the pressure plate to hold the connection between the slope protection wire mesh and the repair wire mesh, tighten the two long bolts on the pressure plate to make the long bolts contact the slope surface. Then, with the support of the three long bolts, the pressure plate can make stable contact with the uneven slope surface, improving the stability of the structure. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a slope protection, buffering, and energy dissipation device, including an anchor rod 1, with a threaded head 14 installed at one end of the anchor rod 1. The threaded head 14 and the anchor rod 1 are integrally formed. The outer surface of the anchor rod 1 is uniformly machined with multiple protrusions, which are integrally formed with the anchor rod 1. A slope protection wire mesh 2 is fitted on the anchor rod 1. An anchor plate 3 is provided on the side of the slope protection wire mesh 2 near the threaded head 14. The anchor plate 3 is fitted on the anchor rod 1. A nut 15 is threadedly connected to the threaded head 14 to press the slope protection wire mesh 2 and the anchor plate 3 onto the slope surface. The structure formed by the anchor plate 3 and the anchor rod 1 restricts the slope protection wire mesh 2 to the slope surface. The deformable property of the slope protection wire mesh 2 is utilized to achieve the purpose of slope protection, buffering, and energy dissipation. The importance of slope buffering and energy dissipation in protecting life and property: Preventing landslides, collapses, and other disasters caused by slope instability from damaging residents, buildings, roads, and infrastructure below, thus avoiding casualties and property losses; Ensuring smooth traffic: For slopes along highways, railways, and other transportation lines, slopes can prevent rockfalls from blocking roads, ensuring normal traffic operation and reducing traffic interruptions and delays caused by slope disasters; Maintaining the stability of engineering facilities: Protecting slopes in water conservancy and hydropower projects, mining projects, etc., ensuring the stable operation of related engineering facilities, and preventing slope problems from affecting the normal use and benefits of the projects; Protecting the ecological environment: Reducing the damage of slope disasters to the surrounding ecological environment, such as preventing vegetation destruction and soil erosion, which is conducive to the balance and stability of the ecosystem.

[0029] See Figures 1-7A threaded cylinder 19 is installed on the side of the nut 15 away from the anchor plate 3. A repair wire mesh 4 is fitted on the threaded cylinder 19. A stud 20 is connected to the internal thread of the threaded cylinder 19. A column 8 is installed at the end of the stud 20 outside the threaded cylinder 19. A hexahedron 9 for engaging a wrench is installed in the middle of the side of the column 8 away from the stud 20. The hexahedron 9 and the column 8 are integrally formed. Both ends of the column 8 are fitted with limiting rings 7 that are connected and fixed to the column 8. There are multiple contacting rings 10 between the two limiting rings 7. The rings 10 are fitted on the column 8 and can rotate around the column 8. A support arm 5 is connected and fixed to the outer surface of the rings 10. A screw rod 11 is threadedly connected to the support arm 5. A detachable pressure plate 12 is installed at one end of the screw rod 11 for pressing and holding the connection between the slope protection wire mesh 2 and the repair wire mesh 4. The pressure plate 12 facing the screw rod 11 has a central... A threaded sleeve 18 is installed at the position, so that the end of the screw 11 near the pressure plate 12 is threaded into the threaded sleeve 18, which facilitates the assembly and disassembly of the screw 11 and the pressure plate 12. The repair wire mesh 4 is covered in the area of ​​the slope protection wire mesh 2 near the anchor plate 3, and the repair wire mesh 4 is connected to the slope protection wire mesh 2. Then, the stud 20 is screwed into the straight threaded cylinder 19 to complete the assembly of the column 8 and the anchor rod 1. Multiple rings 10 rotate around the column 8, and multiple support arms 5 are staggered. Then, the screw 11 is screwed on the support arm 5, so that the pressure plate 12 at one end of the screw 11 presses against the connection between the repair wire mesh 4 and the slope protection wire mesh 2, thereby strengthening the pressure at the connection between the slope protection wire mesh 2 and the repair wire mesh 4. It is not necessary to install new anchor rods at the connection between the slope protection wire mesh 2 and the repair wire mesh 4, which reduces the workload of repairing the slope protection wire mesh 2 and improves the work efficiency of repairing the slope protection wire mesh 2.

[0030] See Figures 1-3 , Figure 5 The support arm 5 plate has multiple first screw holes 6 on one side, which are arranged along the length of the support arm 5 plate. The screw 11 is threaded into the first screw hole 6. The outer surface of the end of the screw 11 away from the pressure plate 12 is equipped with a handle 13. By opening multiple first screw holes 6 on the support arm 5, it is convenient to adjust the position of the screw 11 on the support arm 5 plate, and thus it is convenient to adjust the position of the pressure plate 12 according to the connection between the repair wire mesh 4 and the slope protection wire mesh 2.

[0031] See Figure 4 , Figure 5 and Figure 7A plug 23 for sealing the open end of the threaded cylinder 19 is slidably installed inside the threaded cylinder 19. A positioning plate 25, which is circular, is installed inside the threaded cylinder 19 near the nut 15. A spring 24 is installed between the positioning plate 25 and the plug 23, and the spring 24 is arranged along the length of the threaded cylinder 19. The side of the plug 23 facing the positioning plate 25 is recessed to form a blind hole. The side of the spring 24 away from the positioning plate 25 is installed in the blind hole. A rubber sheet 22, which is circular, is glued to the side of the plug 23 away from the positioning plate 25. The diameter of the plug 23 is smaller than the diameter of the rubber sheet 22, and the diameter of the rubber sheet 22 is the same as the inner diameter of the threaded cylinder 19. With the support of the spring 24, the plug 23 is positioned at the open end of the threaded cylinder 19. The plug 23 acts as a stopper, which seals the open end of the straight threaded cylinder 19 in real time, preventing foreign objects from entering the cylinder and affecting the assembly of the stud 20 and the cylinder 19. When the stud 20 is screwed into the cylinder 19, it presses against the plug 23, which in turn presses against the spring 24, causing the spring 24 to deform elastically. Under the rebound force of the spring 24, the stud 20 and the cylinder 19 are prevented from rotating relative to each other, thus preventing loosening. When the distance between the plug 23 and the positioning piece 25 decreases, the spring 24 is in the blind hole, preventing it from being damaged by excessive compression. By installing a rubber piece 22 on the plug 23, the deformable properties of the rubber piece 22 are utilized to improve the sealing effect on the open end of the straight threaded cylinder 19.

[0032] See Figures 1-3 , Figure 6 Three second screw holes 21 are equidistantly arranged in a ring on one edge of the pressure plate 12. Long bolts 16 are threaded into the second screw holes 21. A knob head 17 is installed at one end of the long bolt 16. The knob head 17 and the bolt 16 are integrally formed. After the pressure plate 12 presses the connection between the slope protection wire mesh 2 and the repair wire mesh 4, the two long bolts 16 on the pressure plate 12 are turned so that the long bolts 16 come into contact with the slope surface. Then, with the support of the three long bolts 16, the pressure plate 12 can make stable contact with the uneven slope surface, thereby improving the stability of the structure.
