A high and steep slope support structure

Abstract

This utility model discloses a support structure for steep slopes, relating to the field of slope protection technology. It includes a support structure with longitudinal and transverse supports intersecting on its inner wall. Pin holes are provided at the connections between the longitudinal and transverse supports, and anchor rods are threaded through the inner walls of these pin holes. Nail heads are fixed to the ends of the anchor rods, fitting snugly against the surface of the pin holes. Metal mesh is laid on the surfaces of the longitudinal and transverse supports. By laying the support structure on the steep slope and using the intersection of the longitudinal and transverse supports to create zones, the load-bearing capacity of the support structure is distributed, stress concentration is avoided, and localized damage prevents overall instability. Furthermore, localized deformation or damage is confined within a certain range by the surrounding mesh, preventing it from rapidly spreading to the entire slope, thus improving safety. A reinforcement mechanism further confines the support structure and anchor rods within the slope body, strengthening the connection with the slope.

Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a high and steep slope protection structure. Background Technology

[0002] With rapid economic development, regions have increasingly higher demands for convenient transportation, leading to the construction of numerous railways, highways, tunnels, and other transportation facilities in mountainous or hilly areas. Steep slopes have become a thorny issue threatening the safe operation of roads.

[0003] Slope protection refers to the measures taken to support, reinforce, and protect slopes to ensure their safety and that of their environment. High and steep slope protection is a common type of slope protection. Commonly used support structures include: gravity retaining walls, buttress retaining walls, cantilever supports, ribbed or lattice-type anchored retaining walls, pile anchored retaining walls, shotcrete supports, and the slope ratio method.

[0004] However, currently, anchor bolts are only connected to slopes through interfacial adhesion or friction. This connection method is easily affected by the external environment (such as weathering, rainwater erosion, temperature changes, etc.), which weakens the connection force and reduces the installation stability of the anchor bolts. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a high and steep slope support structure to solve the problems in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high and steep slope support structure includes: The support structure includes multiple longitudinal supports and multiple transverse supports, which are arranged to cross each other, and each longitudinal support and each transverse support has a pin hole at the connection point. Multiple anchor bolts are installed at the pin holes. Each anchor bolt is equipped with a reinforcement mechanism. The reinforcement mechanism includes a limiting groove and a top block disposed on the limiting groove. The reinforcement mechanism has a first working state and a second working state. When the reinforcement mechanism is in its first working state, the top block is entirely inside the anchor rod; When the reinforcement mechanism is in the second working state, the top block moves outward relative to the anchor rod along the radial direction of the anchor rod through the limiting groove, so that the top block can extend outside the anchor rod and insert into the slope body to prevent the anchor rod from detaching from the slope body.

[0007] Preferably, the end of the anchor rod is provided with a nail cap.

[0008] Preferably, the surface of the support structure is covered with a metal mesh.

[0009] Preferably, the end of the anchor rod is provided with a insertion hole, which extends from one end of the anchor rod toward the other end; The anchor rod has multiple through holes that communicate with the insertion hole on its surface. Each through hole contains a top block, and the top block is slidably connected to the anchor rod through the through hole. The reinforcement mechanism also includes a screw, the insertion hole is provided with a thread that meshes with the screw, the top block is provided with a thread that meshes with the screw on the side near the screw, and the thread on the surface of the top block meshes with the screw.

[0010] Preferably, the screw is used to switch the reinforcement mechanism to the first working state or the second working state; When the reinforcement mechanism is in the first working state, the screw moves toward the end away from the slope so that the screw is partially or completely disengaged from the insertion hole, so that the top block moves toward the insertion hole inside the anchor rod under the drive of the screw thread; When the reinforcement mechanism is in the second working state, the screw is threadedly connected to the insertion hole and inserted into the insertion hole in the direction of the slope, so that the top block moves in the direction of the anchor rod under the drive of the screw thread to insert into the slope body to prevent the anchor rod from separating from the slope body.

[0011] Preferably, the limiting groove is disposed on the inner wall of the through hole, and an I-shaped slider corresponding to the limiting groove is fixedly installed at the end of the top block, and the top block is slidably connected to the limiting groove through the I-shaped slider.

[0012] Preferably, the plurality of through holes are respectively arranged in an array on two opposite sides of the anchor rod; The top block has an inclined structure, and the top blocks located in the through holes on two opposite sides of the anchor rod are symmetrically arranged with the screw rod as the center.

[0013] Preferably, the screw end face has a cross groove.

[0014] Preferably, the support structure further includes a mounting frame, in which the plurality of longitudinal supports and the plurality of transverse supports are disposed, and the two ends of the longitudinal supports and the transverse supports are respectively connected to the inner wall of the mounting frame.

[0015] Preferably, positioning holes are provided at all four corners of the mounting frame.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. This utility model provides a high and steep slope support structure. After the anchor rod is driven into the slope, a reinforcement mechanism is used to further limit the support structure and the anchor rod within the slope body, enhancing the connection effect with the slope body. Specifically, the screw rod is threaded onto the inner wall of the insertion hole. During the process, the screw rod engages with the top block, thereby squeezing the top block and causing it to slide on the inner wall of the through hole. This causes the top block to protrude from the surface of the anchor rod and penetrate into the interior of the slope, thus firmly fixing the anchor rod to the high slope. This avoids the anchor rod and the slope being connected only through interface adhesion and friction, thereby improving the stability of the anchor rod installation.

[0017] 2. This utility model provides a high and steep slope support structure. By laying the support structure on the high and steep slope and dividing it into sections by the intersection of longitudinal and transverse supports, the bearing capacity of the support structure is distributed more evenly. This can distribute the sliding force and lateral earth pressure of the slope soil more evenly to the entire support structure and anchors, avoid stress concentration, prevent local damage from causing overall instability, and limit local deformation or damage to a certain range by the surrounding mesh, making it less likely to spread rapidly to the entire slope, thus improving safety. The metal mesh can also effectively block small gravel, preventing injury to workers. Attached Figure Description

[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] like Figures 1 to 5As shown, the present invention provides a high and steep slope support structure, including a support structure 1. The inner wall of the support structure 1 is provided with longitudinal support rods 11 and transverse support rods 12. A pin hole 13 is provided at the connection between the longitudinal support rods 11 and the transverse support rods 12. An anchor rod 2 is provided through the inner wall of the pin hole 13. A nail head 21 is fixed at the end of the anchor rod 2. The nail head 21 is attached to the surface of the pin hole 13. Metal mesh is laid on the surface of the longitudinal support rods 11 and the transverse support rods 12. By laying the support structure 1 on the steep slope and dividing it into sections by the intersection of longitudinal support rods 11 and transverse support rods 12, the bearing capacity of the support structure 1 is distributed more evenly. This allows the sliding force and lateral earth pressure of the slope soil to be distributed more evenly across the entire support structure 1 and anchor rods 2, avoiding stress concentration and preventing local damage from causing overall instability. Furthermore, local deformation or damage is confined to a certain range by the surrounding mesh, making it less likely to spread rapidly to the entire slope. This improves the redundancy and safety of the system. The metal mesh also provides a good barrier effect against small gravel, preventing injury to workers.

[0022] The anchor bolt 2 is equipped with a reinforcement mechanism, which includes a limiting groove 24 and a top block 26 disposed on the limiting groove 24. The reinforcement mechanism has a first working state and a second working state. When the reinforcement mechanism is in its first working state, the top block 26 is completely inside the anchor rod 2; When the reinforcement mechanism is in the second working state, the top block 26 moves outward relative to the anchor rod 2 in the radial direction of the anchor rod 2 through the limiting groove 24, so that the top block 26 can extend out of the anchor rod 2 and insert into the slope body to prevent the anchor rod 2 from separating from the slope body.

[0023] Specifically, the reinforcement mechanism also includes a screw 27, which is used to switch the reinforcement mechanism to a first working state or a second working state; When the reinforcement mechanism is in the first working state, the screw 27 moves toward the end away from the slope so that the screw 27 is partially or completely disengaged from the insertion hole 22, so that the top block 26 moves toward the insertion hole 22 inside the anchor rod 2 under the thread drive of the screw 27. When the reinforcement mechanism is in the second working state, the screw 27 is threadedly connected to the insertion hole 22 and inserted into the insertion hole 22 in the direction of the slope, so that the top block 26 moves in the direction of the anchor rod 2 outward under the thread of the screw 27, so as to insert into the slope body to prevent the anchor rod 2 from separating from the slope body.

[0024] An anchor rod 2 has a recessed insertion hole 22 at its end, and a through hole 23 communicating with the insertion hole 22 is opened through the surface of the anchor rod 2. A top block 26 is slidably sleeved on the inner wall of the through hole 23, and a screw 27 is threadedly sleeved on the insertion hole 22. The top block 26 has a thread on the side near the screw 27, and the thread on the surface of the top block 26 is engaged with the screw 27. After the anchor rod 2 is driven into the slope, the screw rod 27 is threaded onto the inner wall of the insertion hole 22. During this process, the screw rod 27 engages with the top block 26, thereby squeezing the top block 26 and causing it to slide on the inner wall of the through hole 23. This causes the top block 26 to protrude from the surface of the anchor rod 2 and penetrate into the slope body, thus firmly fixing the anchor rod 2 to the high slope. This avoids the anchor rod 2 and the slope being connected only through interface adhesion and friction, thereby improving the stability of the anchor rod 2 installation.

[0025] A limiting groove 24 is recessed in the inner wall of the through hole 23. An I-shaped slider 25 is fixedly installed at the end of the top block 26. The I-shaped slider 25 slides in the limiting groove 24. When the screw 27 is not inserted into the insertion hole 22, the top block 26 can retract into the through hole 23 by the threaded connection when the screw 27 moves out of the insertion hole 22, so as to avoid affecting the anchor rod 2 when it is driven into the slope. When the screw 27 is inserted into the insertion hole 22, the sliding of the I-shaped slider 25 on the inner wall of the limiting groove 24 plays a limiting role, preventing the top block 26 from sliding out of the through hole 23.

[0026] If necessary, an elastic pull rope can also be provided outside the through hole 23. When the screw 27 is inserted into the insertion hole 22, the top block 26 extends out of the through hole 23 and causes the elastic pull rope to undergo elastic stretching deformation. When the screw 27 is not inserted into the insertion hole 22 or moves out of the insertion hole 22, the elastic pull rope recovers so that the top block 26 can be retracted into the through hole 23 by the elastic force of the elastic pull rope.

[0027] The top block 26 has an inclined structure, and the top blocks 26 on both sides are symmetrical about the screw 27 as the center; The end face of the screw 27 has a cross groove recessed inside; Positioning holes 28 are provided at all four corners of the support structure 1; and positioning steel nails are installed at the positioning holes. By inserting the positioning steel nails into the slope, the support structure 1 can be firmly covered on the slope to prevent it from falling off and improve the protection effect.

[0028] The support structure 1 includes a plurality of longitudinal supports 11 arranged in parallel with each other, and a plurality of transverse supports 12 arranged in parallel with each other. The support structure 1 also includes a mounting frame, in which the plurality of longitudinal supports 11 and the plurality of transverse supports 12 are arranged, and the two ends of the longitudinal supports 11 and the transverse supports 12 are respectively connected to the inner wall of the mounting frame.
