Description

Technical Field

[0001] This utility model relates to the field of slope protection structure technology, and more specifically, to a composite slope protection structure of anchor bolts and gabion mesh. Background Technology

[0002] In the field of slope protection engineering, traditional single anchor reinforcement is difficult to take into account surface protection, and single gabion mesh reinforcement lacks deep stability support. Moreover, both have insufficient drainage function, making it difficult for the protection system to cope with complex geological conditions and extreme climate environment, and unable to effectively resist the risk of soil weathering, collapse and landslide. Against this background, the composite slope protection structure of anchor and gabion mesh has emerged.

[0003] In the production process, the existing publication CN119896135A discloses a slope protection structure for vegetation buffer zone restoration, including a fixed base, an adjustment mechanism rotatably connected to the fixed base, an adjustment base rotatably connected to the adjustment mechanism, a rotating rod rotatably connected to the adjustment base, two slope protection frames fixedly connected to the rotating rod, multiple U-shaped frames fixedly connected to the slope protection frames, a reed planting mechanism rotatably connected to the U-shaped frames, a wave-breaking plate fixedly connected to one side of the U-shaped frame, and a sunshade mechanism rotatably connected inside the wave-breaking plate. By setting the reed planting mechanism on the slope protection frame, and by rotating the rod, the angle of the slope protection frame can be adjusted to suit the shallow water area of ​​the reservoir, thereby straightening and fixing the reeds planted in the shallow water area of ​​the reservoir. This utilizes the natural advantages of reeds to help restore the slope protection and soil and water conservation functions in water conservancy projects, enabling it to play an ecological restoration role in waterside areas such as shallow water areas of reservoirs. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing single-anchor slope protection structures rely solely on the anchor bolts themselves penetrating into the rock mass, resulting in a single anchoring method and a lack of coordinated reinforcement between components. This makes it difficult to fully transfer shallow loads to deep, stable strata, and there is no effective surface protection, making it unable to resist soil weathering and collapse. Furthermore, while traditional single gabion mesh reinforcement can cover the slope surface and use the weight of the stones to constrain the surface soil, it lacks deep, stable support. When encountering large soil displacements or landslide thrust, it is difficult to provide sufficient anti-sliding force, resulting in limited protective effects.

[0005] Therefore, a composite slope protection structure of anchor bolts and gabion mesh is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a composite slope protection structure of anchor bolts and gabion mesh to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a composite slope protection structure of anchor bolts and gabion mesh, including an anchoring mechanism, a gabion mesh mechanism, and a drainage component. The gabion mesh mechanism is installed on the side of the anchoring mechanism, and a drainage component is installed on the side of the gabion mesh mechanism away from the anchoring mechanism. The drainage component includes a guide plate, a diversion pipe, and a discharge pipe. A drainage pipe is installed below the guide plate, and a diversion pipe is installed on the side of the guide plate.

[0008] Preferably, the anchoring mechanism includes a main body component, a connecting component, and an anchor component, wherein the anchor component is mounted on the outer diameter surface of the main body component, and the connecting component is provided on the outer diameter surface of the anchor component.

[0009] Preferably, the main component includes a first anchor rod, a second anchor rod, and an anchor rod sleeve, wherein the second anchor rod is provided on the side of the first anchor rod, and the anchor rod sleeve is provided on the outer diameter surface of the second anchor rod.

[0010] Preferably, the anchor sleeve includes a sleeve body, a grouting pipe and a grout outlet pipe, and the grouting pipe is installed on the side of the sleeve body, and the grout outlet pipe is provided on the side of the grouting pipe away from the sleeve body.

[0011] Preferably, the connecting assembly includes a pressure plate, an anti-loosening component, and a fixing steel pipe, with the anti-loosening component installed on the top of the pressure plate and the fixing steel pipe installed on the side of the pressure plate.

[0012] Preferably, the anti-loosening component includes an anti-loosening bolt, a first rubber ring, and a second rubber ring, wherein the first rubber ring is provided on the outer diameter surface of the anti-loosening bolt, and the second rubber ring is provided below the first rubber ring.

[0013] Preferably, the anchor assembly includes an anchor fixing ring, an anchor cap, and a fixing steel bar, wherein the anchor fixing ring is fitted with an anchor cap on its side, and the anchor cap is provided with a fixing steel bar on its inner side wall.

[0014] Preferably, the gabion structure includes gabion mesh panels, edge wires, and a fixed steel frame, with edge wires installed on the side of the gabion mesh panels and a fixed steel frame installed on the side of the edge wires away from the gabion mesh panels.

[0015] Preferably, the fixed steel frame includes a vertical tube, a horizontal tube, and edge steel plates, and the edge steel plates are installed on the side of the horizontal tube, and the vertical tube is provided below the horizontal tube.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Compared with existing technologies, this composite slope protection structure of anchor bolts and gabion mesh forms a flexible integral slope cover after the gabion mesh is filled with stones. With the self-weight of the stones and the restraining force of the mesh, it can resist the weathering and collapse of the surface soil and adapt to the local deformation of the slope, thus playing a surface protection role for the local slope.

[0018] Compared with existing technologies, this composite slope protection structure of anchor bolts and gabion mesh connects the first and second anchor bolts through anchor bolt sleeves, significantly extending the anchoring depth. It also utilizes the "anchor-grout-rock" composite to enhance the bond strength with the soil and rock, effectively transferring shallow loads to deep, stable strata and greatly improving the overall stability of the slope. At the same time, its anchor assembly integrates multiple anchor bolts, making the tension distribution more uniform and avoiding local stress concentration. The combination of gabion mesh and anchor bolts achieves integrated protection from deep slope stabilization to surface protection, ensuring the overall stability of the slope and improving the durability of the protective structure.

[0025] 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. Example 1

[0026] As attached Figures 1 to 5 The illustrated anchor bolt and gabion mesh composite slope protection structure includes an anchoring mechanism 1, a gabion mesh mechanism 2, and a drainage component 3. The gabion mesh mechanism 2 is installed on the side of the anchoring mechanism 1, and the drainage component 3 is installed on the side of the gabion mesh mechanism 2 away from the anchoring mechanism 1.

[0027] Among them: when the anchoring mechanism 1 penetrates into the rock mass of the slope, it uses its own tensile properties and the bonding force formed by grouting to transfer the shallow load to the deep stable stratum, restrict the displacement of the soil, and provide stable support. The gabion mechanism 2 is installed on the outside of the anchoring mechanism 1. Its flexible structure is filled with stones and fits tightly against the slope surface. It relies on the weight of the stones and the constraint force to resist the weathering and collapse of the surface soil. The drainage component 3 is set on the outside of the gabion mechanism 2. The inclined structure guides the rainwater on the slope surface to drain quickly, avoids rainwater seeping into the slope, reduces pore water pressure, and reduces the risk of landslides caused by water damage. Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0029] In a preferred embodiment, the anchoring mechanism 1 includes a main body component 4, a connecting component 5, and an anchor component 6. The anchor component 6 is installed on the outer diameter surface of the main body component 4, and the connecting component 5 is provided on the outer diameter surface of the anchor component 6. The main body component 4 is embedded in the rock mass. The tensile strength of the main body component 4 and the bonding force of the grout restrict the displacement of the slope soil. The connecting component 5 connects and fixes the anchoring mechanism 1 and the gabion mechanism 2. The anchor component 6 ensures that the tensile force of the main body component 4 is effectively applied to the slope surface and can integrate multiple main body components 4.

[0030] In a preferred embodiment, the main component 4 includes a first anchor rod 7, a second anchor rod 8, and an anchor sleeve 9. The second anchor rod 8 is disposed on the side of the first anchor rod 7, and the anchor sleeve 9 is disposed on the outer diameter surface of the second anchor rod 8. The first anchor rod 7 and the second anchor rod 8 are connected by the anchor sleeve 9, extending the anchoring depth. Grouting is performed in conjunction with the grouting pipe 11 and the grout outlet pipe 12 inside the anchor sleeve 9, so that the anchor rod and the slope rock and soil form an "anchor-grout-rock" composite. After grouting, the cement grout fills the gap between the anchor sleeve 9 and the rock and soil, forming a gripping force, transferring the shallow load of the slope to the deep stable strata, and resisting the sliding force.

[0031] In a preferred embodiment, the anchor sleeve 9 includes a sleeve body 10, a grouting pipe 11, and a grout outlet pipe 12. The grouting pipe 11 is installed on the side of the sleeve body 10, and the grout outlet pipe 12 is provided on the side of the grouting pipe 11 away from the sleeve body 10. After connecting the first anchor 7 and the second anchor 8 using the anchor sleeve 9, pressurized grouting is performed into the sleeve body 10 through the grouting pipe 11. When the grout overflows from the grout outlet pipe 12, the operator needs to stop grouting and wait for the injected concrete to solidify. Then, the anchoring mechanism 1 is fixed into the interior of the slope rock and soil, so that the anchor and the slope rock and soil form an "anchor-grout-rock" composite. After grouting, the cement grout fills the gap between the anchor sleeve 9 and the rock and soil, forming a gripping force, transferring the shallow load of the slope to the deep stable strata, and resisting the sliding force.

[0032] In a preferred embodiment, the connecting assembly 5 includes a pressure plate 13, an anti-loosening component 14, and a fixing steel pipe 15. The anti-loosening component 14 is installed on the top of the pressure plate 13, and the fixing steel pipe 15 is installed on the side of the pressure plate 13. The pressure plate 13 is close to the slope surface, so as to evenly transmit the anchor bolt tension to the surface soil. The anti-loosening component 14 fixes the anchor assembly 6 to the connecting assembly 5. The fixing steel pipe 15 connects the pressure plate 13 and the gabion mechanism 2 to form a rigid-flexible force transmission path.

[0033] In a preferred embodiment, the anti-loosening component 14 includes an anti-loosening bolt 16, a first rubber ring 17, and a second rubber ring 18. The first rubber ring 17 is provided on the outer diameter surface of the anti-loosening bolt 16, and the second rubber ring 18 is provided below the first rubber ring 17. The anti-loosening bolt 16, together with the first rubber ring 17 and the second rubber ring 18, forms an elastic buffer to prevent the anti-loosening bolt 16 from loosening due to minor deformation of the slope.

[0034] In a preferred embodiment, the anchor assembly 6 includes an anchor bolt fixing ring 19, an anchor cap 20, and a fixing steel bar 21. The anchor cap 20 is installed on the side of the anchor bolt fixing ring 19, and the fixing steel bar 21 is provided on the inner side of the anchor cap 20. The anchor bolt fixing ring 19 locks the end of the anchor bolt and integrates multiple anchor bolts. The anchor bolts are fixed by the fixing steel bar 21 at intervals. The anchor cap 20 and the anchor bolt fixing ring 19 are interference fit to seal the end face of the anchor bolt.

[0035] In a preferred embodiment, the gabion structure 2 includes gabion mesh 22, edge wires 23, and a fixed steel frame 24. The edge wires 23 are installed on the side of the gabion mesh 22, and the fixed steel frame 24 is installed on the side of the edge wires 23 away from the gabion mesh 22. The gabion mesh 22 is woven from low-carbon steel wire into a gabion structure. After being filled with stones, it forms a flexible whole that closely covers the slope. The gabion mesh 22 is connected to the fixed steel frame 24 through the edge wires 23. While adapting to local deformation of the slope, it uses the weight of the stones and the restraining force of the mesh to prevent the weathering and collapse of the surface soil.

[0036] In a preferred embodiment, the fixed steel frame 24 includes vertical tubes 25, horizontal tubes 26, and edge steel plates 27. Edge steel plates 27 are installed on the sides of the horizontal tubes 26, and vertical tubes 25 are arranged below the horizontal tubes 26. The vertical tubes 25 and the horizontal tubes 26 form a grid-like support skeleton. The edge steel plates 27 fix the boundary of the mesh, distribute the local load of the gabion cage to the entire steel frame, avoid excessive local stress on the mesh and tearing, and enhance the overall integrity of the surface protection.

[0037] In a preferred embodiment, the drainage assembly 3 includes a guide plate 28, a diversion pipe 29, and a discharge pipe 30. A discharge pipe is installed below the guide plate 28, and a diversion pipe 29 is installed on the side of the guide plate 28. The guide plate 28 is inclined and set outside the gabion mesh to guide rainwater on the slope to flow downward along the plate surface and flow out from the diversion pipe 29. The discharge pipe leads directly to the ground. When the rainfall is heavy, the operator can open the discharge pipe to directly introduce the rainwater into the ground.

[0038] The working process of this utility model is as follows: First, the anchoring mechanism 1 is embedded in the rock mass. The first anchor rod 7 and the second anchor rod 8 in its main component 4 are connected by the anchor sleeve 9 to extend the anchoring depth. When the anchor sleeve 9 is grouted, pressurized grouting is performed into the sleeve body 10 through the grouting pipe 11. When the grout overflows from the grout outlet pipe 12, the operator needs to stop the grouting and wait for the injected concrete to solidify. Then, the anchoring mechanism 1 is fixed to the interior of the slope rock and soil to form an "anchor-grout-rock" composite. The tensile strength of the main component 4 and the bonding force of the grout limit the displacement of the slope soil. The anchor component 6 includes an anchor fixing ring 19, an anchor cap 20 and a fixing steel bar 21. By locking the end of the anchor rod and integrating multiple main components 4, it ensures that the tension is effectively applied to the slope surface. The bearing plate 13 of the connecting component 5 transmits the anchor rod tension to the surface soil.

[0039] The anti-loosening bolts 16 of the anti-loosening component 14 form an elastic buffer with the first rubber ring 17 and the second rubber ring 18 to prevent loosening. The fixed steel pipe 15 connects to the gabion mechanism 2, so that the gabion mechanism 2 and the anchoring mechanism 1 form a fixed whole. In the gabion mechanism 2, the gabion mesh 22 is connected to the fixed steel frame 24 composed of vertical pipe 25, horizontal pipe 26 and edge steel plate 27 through the edge steel wire 23. After filling with stones, a flexible whole is formed to cover the slope surface. The self-weight of the stones and the restraint force of the mesh prevent the soil from weathering and collapsing. The fixed steel frame 24 disperses the local load to enhance the overall integrity. In the drainage component 3, the guide plate 28 is inclined to guide rainwater down the plate surface and into the discharge pipe 30 through the diversion pipe 29. When the rainfall is large, the rainwater can be introduced into the ground through the drainage pipe. The three work together to achieve deep anchoring of the slope, surface protection and water hazard control. The above is the working principle of this composite slope protection structure of anchor rod and gabion mesh.
