A highway slope reinforcement device

Abstract

This invention relates to the field of slope reinforcement, and more particularly to a highway slope reinforcement device, comprising a reinforcement device body installed on the surface of the slope body. The reinforcement device body is arranged at equal intervals along the surface of the slope body. The reinforcement device body includes slope reinforcement components, inserts, protective components, and reinforcing ribs through which pipes pass. The inserts are implanted into the slope body at an inclined downward position. Their flared cross-section design allows the large diameter end to face outward and the small diameter end to penetrate inward. When rainwater seeps in and softens the surrounding soil, the flared structure does not simply rely on lateral friction resistance during the stress process. Instead, it transforms the downward trend into an active wedging of the surrounding soil through the inclined embedding posture. That is, under external loads such as the displacement of the upper soil or local collapse, when the inserts undergo slight displacement along the inclined direction, their flared edges will continuously squeeze and reshape the adjacent soil, forming a dynamically self-reinforcing dense zone.

Description

Technical Field

[0001] This invention relates to the field of slope reinforcement, specifically a highway slope reinforcement device. Background Technology

[0002] Rainfall is one of the main causes of instability in highway ecological slopes. This instability is caused by the erosive power of rainwater. Under continuous rainfall conditions, the surface soil of highway slopes is easily eroded by runoff and precipitation. Instability of highway ecological slopes will have an adverse impact on driving safety. The existing treatment method is to build a U-shaped retaining wall on the slope surface and cover the middle of the retaining wall with netting and vegetation to stabilize the soil and prevent falling objects from the soil surface. However, in cases of heavy rainfall, this method of remediation can lead to vegetation and soil loss due to the small planting area, exposing stones in the soil. Under the continuous erosion of rainwater, these stones are very likely to detach from the soil and fall. The existing retaining wall surface is covered with a fixed connection point to the retaining wall and does not have a corresponding buffer structure. When larger stones detach from the soil and fall, the netting is easily torn by gravity. Summary of the Invention

[0003] This invention provides a highway slope reinforcement device that overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this invention to solve its technical problem is: A highway slope reinforcement device includes a reinforcement device body installed on the surface of the slope body. The reinforcement device body is arranged at equal intervals along the surface of the slope body. The reinforcement device body includes a slope reinforcement component, an insert, a protective component, and a reinforcing rib penetrating through the slope reinforcement component. The insert is located on the side of the slope reinforcement component close to the slope body and is inclined downward. The reinforcing rib penetrates through the insert and is inserted into the slope body. The protective component is located on the side of the insert away from the slope body. An angle is formed between the protective component and the insert, and there is a gap between the insert and the protective component for falling objects to pass through. The embedded part has a flared cross-section, with the larger diameter end of the embedded part facing the protective part. The embedded part is inserted into the slope body from the outside to the inside, and the slope reinforcement part is abutted against the surface of the slope body. The lower horizontal plane of the embedded part is lower than the lower horizontal plane of the slope reinforcement part.

[0005] In a preferred embodiment, the end of the embedded member near the slope reinforcement member is provided with a vegetation layer, and the vegetation layer is arranged equidistantly between the protective member and the slope reinforcement member.

[0006] In a preferred embodiment, the insert is provided with a filling cavity for accommodating soil and stones, the filling cavity is connected to the notch, a reinforcing rib is provided in the filling cavity, and an outwardly protruding intercepting protrusion is provided at the lower end of the filling cavity, the intercepting protrusion being provided near the small diameter end of the insert. The upper end of the filling cavity is provided with multiple outwardly communicating guide holes, which extend along the width direction of the filling cavity.

[0007] In a preferred embodiment, the protective component includes a frame, a safety net, and a buckle plate. Two rotating shafts are symmetrically arranged on the side of the lower end of the slope reinforcement component away from the embedded component. The frame is rotatably connected to the rotating shafts through a connecting shaft at its lower end. The frame has a notch in the middle, and a net covers the surface of the notch. One end of the net is connected to the upper edge of the notch, while the other end is fixed to the surface of the frame by a buckle plate. The buckle plate has a C-shaped cross section and is fastened to the lower surface of the notch. The buckle plate also has a handle on its surface.

[0008] In a preferred embodiment, the frame surface is further provided with a fixing strip for fixing the net. The fixing strip has a C-shaped structure, the opening of the fixing strip faces the buckle plate, the fixing strip is fixed to the edge of the net, and there is a gap between the fixing strip and the buckle plate.

[0009] In a preferred embodiment, the protective component is inclined, and the slope reinforcement component has an outwardly protruding part on the side near the protective component. The protruding part abuts against the lower end of the frame near the slope reinforcement component. The slope reinforcement component is symmetrically provided with limiting posts on the side away from the protruding part, and both limiting posts abut against the side of the frame away from the buckle plate. When the frame is stationary, it abuts against both the limiting post and the protrusion.

[0010] In a preferred embodiment, the limiting post includes an outer tube, a telescopic post, and a spring. The telescopic post is movably installed inside the outer tube. A magnetic block for adsorbing the frame is provided on the side of the telescopic post away from the outer tube. The spring is located inside the outer tube and is connected to the end of the telescopic post away from the magnetic block. When the frame rests against the surface of the telescopic column and is stationary, the spring is not under force.

[0011] Compared with existing technologies, this technical solution has the following advantages: The insert is implanted into the slope at an angle downwards. Its flared cross-section design makes the large diameter end face outwards and the small diameter end penetrate inwards. When rainwater seeps in and softens the surrounding soil, the flared structure does not simply rely on side friction resistance during the stress process. Instead, it transforms the downward trend into an active wedging into the surrounding soil through the flared embedding posture. That is, when the insert undergoes a small displacement along the inclined direction under external loads such as the upper soil displacement or local collapse, its flared edge will continuously squeeze and reshape the adjacent soil, forming a dynamically self-reinforcing dense zone.

[0012] Furthermore, the filling cavity is directly connected to the notch, allowing soil and gravel sliding down from above to fall naturally into the cavity. Reinforcing ribs are installed axially along the center of the cavity, with the portion inside the cavity encased by the filled soil and gravel, enhancing the frictional interlocking between the ribs and the soil. An intercepting protrusion is located at the lower end of the filling cavity, near the small-diameter end of the insert. Its outward convex profile smoothly transitions with the flared inner wall of the insert, neither hindering the smooth sliding of soil and gravel into the cavity under gravity nor hindering the gravel from sliding further out along the inclined direction of the insert when it reaches the bottom of the cavity. This ensures that the fallen material is stably retained in the lower part of the cavity. This retention effect causes the filling cavity to gradually accumulate local mass during service, increasing not only the overall weight of the insert but also, due to its location on the outer side of the lower end of the insert, significantly increasing the anti-overturning moment of the device around the lower fulcrum of the insert. This effectively suppresses any slight rotation or upward tendency that may occur after rainfall softens the soil. Attached Figure Description

Detailed Implementation

[0024] like Figures 1 to 9 As shown, the present invention proposes a highway slope reinforcement device, including a reinforcement device body 1 installed on the surface of a slope body 100. The reinforcement device body 1 is arranged at equal intervals along the surface of the slope body 100. The reinforcement device body 1 includes a slope reinforcement component 11, an insert 12, a protective component 13, and a reinforcing rib 14 that passes through the slope reinforcement component 11. The insert 12 is disposed on the side of the slope reinforcement component 11 close to the slope body 100 and is inclined downward. The reinforcing rib 14 passes through the insert 12 and is inserted into the slope body 100. The protective component 13 is disposed on the side of the insert 12 away from the slope body 100. An angle is formed between the protective component 13 and the insert 12, and there is a gap between the insert 12 and the protective component 13 for falling objects to pass through. The embedded part 12 has a flared cross section, with the larger diameter end of the embedded part 12 facing the protective part 13. The embedded part 12 is inserted into the slope body 100 from the outside to the inside. The slope reinforcement part 11 abuts against the surface of the slope body 100, and the lower horizontal plane of the embedded part 12 is lower than the lower horizontal plane of the slope reinforcement part 11.

[0025] The insert 12 is implanted into the slope at an angle downward. Its flared cross-section design makes the large diameter end face outward and the small diameter end go inward. When rainwater seeps in and softens the surrounding soil, the flared structure does not rely solely on side friction resistance during the stress process. Instead, it transforms the downward trend into an active "wedge-compact" effect on the surrounding soil through the flared embedding posture. When the embedded part 12 undergoes a slight displacement along the inclined direction under external loads such as the displacement of the upper soil or local collapse, its flared edge will continuously squeeze and reshape the adjacent soil, forming a dynamic self-reinforcing annular dense area. On this basis, since the protective part 13 is arranged on the outside of the slope reinforcement part 11, all the stones that roll down from above will enter through the gap between the protective part 13 and the slope reinforcement part 11. This gap is suitable for collecting the soil and gravel falling from above. This gap is defined by the side surface of the embedded part 12 away from the slope body 100 and the side surface of the protective part 13 facing the slope body 100. When rainfall causes the upper soil to loosen, the surface vegetation to fall off, or local shallow peeling, the fallen soil particles and gravel slide down the slope under the action of gravity and fall directly into the gap area. Because the insert 12 is inclined downward and its lower end is lower than the lower end of the slope reinforcement member 11, the gap has a vertical height difference from top to bottom. At the same time, the large-diameter end of the flared section of the insert 12 faces outward, and its inner wall forms an outwardly opening guide surface at the entrance of the gap, which can effectively expand the capture range and guide the falling objects into the gap. After the falling objects enter the gap, they are limited by the space between the insert 12 and the protective member 13 and can only slide down along the length of the gap. Finally, they are collected between the slope reinforcement member 11 and the protective member 13, so that the matrix-arranged reinforcement device body 1 can evenly collect the falling rocks or soil.

[0026] Furthermore, a vegetation layer 2 is provided at one end of the embedded member 12 near the slope reinforcement member 11, and the vegetation layer 2 is arranged equidistantly between the protective member 13 and the slope reinforcement member 11.

[0027] Furthermore, the insert 12 is provided with a filling cavity 121 for accommodating soil and stones. The filling cavity 121 is connected to the notch. The reinforcing rib 14 is disposed in the filling cavity 121. An outwardly protruding intercepting protrusion 122 is provided at the lower end of the filling cavity 121. The intercepting protrusion 122 is disposed near the small diameter end of the insert 12. The upper end of the filling cavity 121 is provided with a plurality of outwardly communicating guide holes 123, which extend along the width direction of the filling cavity 121. Because the filling cavity 121 is directly connected to the notch, the soil and gravel sliding down from above can fall naturally into the cavity. The reinforcing rib 14 is installed through the cavity along the central axis, and the part of it located in the cavity is wrapped by the filled soil and gravel, which enhances the frictional interlocking between the rib and the soil. The intercepting protrusion 122 is located at the lower end of the filling cavity 121, near the small diameter end of the insert 12. Its outward convex contour smoothly transitions with the inner wall of the flared opening of the insert 12. It does not hinder the soil and gravel from sliding smoothly into the cavity under the action of gravity, and it can also form a physical limit when the gravel reaches the bottom of the cavity, preventing it from continuing to slide out along the inclined direction of the insert 12, thereby ensuring that the fallen material is stably retained in the lower part of the cavity. This retention effect causes the filling cavity 121 to gradually accumulate local mass during service, which not only increases the overall weight of the insert 12, but also significantly increases the anti-overturning moment of the device around the lower end support point of the insert due to its position on the outer side of the lower end of the insert 12, effectively suppressing the slight rotation or upward tendency that may occur after the soil is softened by rainfall. Furthermore, since the guide hole 123 is located on the upper side wall of the filling cavity 121 and extends along the width of the cavity, and is arranged horizontally or slightly downwardly, the guide hole 123 provides a directional growth entrance for the vegetation layer 2 or the roots of the planted trees on the slope surface. The roots can extend into the filling cavity 121 through the hole and continue to develop in the soil and rock medium inside the cavity. Vegetation with longer roots can also wrap around the surface of the reinforcing rib 14 and the surrounding filling material, improving the fixation of the soil and the body 1 of the reinforcement device.

[0028] Furthermore, the protective component 13 includes a frame 131, a net 132, and a buckle plate 133. The slope reinforcement component 11 has two symmetrical rotating shafts 113 on the side away from the embedded component 12 at its lower end. The frame 131 is rotatably connected to the rotating shafts 113 through the connecting shaft 1311 at its lower end. The frame 131 has a notch in the middle, and a net 132 covers the surface of the notch. One end of the net 132 is connected to the upper edge of the notch, while the other end is fixed to the surface of the frame 131 by a buckle 133. The buckle 133 has a C-shaped cross section and is fastened to the lower surface of the notch. A handle 1331 is also provided on the surface of the buckle 133.

[0029] As can be seen above, the protective component 13 achieves graded interception and controlled discharge of falling soil and rocks through the mechanical linkage structure of the frame 131, the net 132, and the buckle plate 133: the lower end of the frame 131 is connected to the lower end of the slope reinforcement component 11 via the connecting shaft 1311 to form a rotatable hinge, giving it the freedom to rotate upwards around the rotating shaft 113; the net 132 covers the surface of the notch in the middle of the frame 131, with its upper end fixed to the upper edge of the notch, and its lower end fastened and pressed against the lower edge of the notch by the C-shaped buckle plate 133 from below, forming a closed support surface; when the soil or gravel above passes through the insert 12 and When the object slips through the gap between the protective components 13, it first enters the gap area in the middle of the frame 131 and is caught by the net 132. The net 132 is initially in a tensioned state, but because the buckle 133 only limits it from the bottom and does not lock it rigidly, when the object impacts or accumulates a certain weight, the net 132 undergoes a localized controlled sagging deformation, causing the object to slide along the surface of the net 132 and remain stably in the concave support area formed by the net 132 and the frame 131. This design avoids the stress concentration and tearing problem caused by the rigid connection of traditional fixed nets, and instead uses the structural rotation and mesh deformation to dissipate energy. During maintenance, the operator only needs to hold the handle 1331 and pull the buckle plate 133 upwards. The pulling action can quickly remove it from the lower edge of the gap, release the constraint on the lower end of the net 132, and the net 132 will then unfold and hang down. The collected soil and rocks will slide smoothly out along the surface of the net 132 to the slope foot aggregate area under the action of gravity, completing the emptying.

[0030] Furthermore, the surface of the frame 131 is also provided with a fixing strip 134 for fixing the net 132. The fixing strip 134 has a C-shaped structure, and the opening of the fixing strip 134 is set towards the buckle plate 133. The fixing strip 134 is fixed to the edge of the net 132, and there is a gap between the fixing strip 134 and the buckle plate 133.

[0031] Furthermore, the protective component 13 is inclined, and the slope reinforcement component 11 has an outwardly protruding protrusion 112 on the side near the protective component 13. The protrusion 112 abuts against the lower end of the frame 131 near the slope reinforcement component 11. The slope reinforcement component 11 has symmetrically arranged limiting posts 111 on the side away from the protrusion 112. Both limiting posts 111 abut against the side of the frame 131 away from the buckle plate 133. When the frame 131 is stationary, it abuts against both the limiting posts 111 and the protrusion 112.

[0032] Furthermore, the limiting post 111 includes an outer tube 1111, a telescopic post 1112, and a spring 1113. The telescopic post 1112 is movably installed inside the outer tube 1111. A magnetic block for adsorbing the frame 131 is provided on the side of the telescopic post 1112 away from the outer tube 1111. The spring 1113 is disposed inside the outer tube 1111 and connected to the end of the telescopic post 1112 away from the magnetic block. When the frame 131 abuts against the surface of the telescopic post 1112 and is stationary, the spring 1113 is not under force.

[0033] When a falling object impacts the frame 131 or the accumulated weight causes it to attempt to rotate outward around the pivot 113, its abutting side first overcomes the magnetic attraction and compresses the spring 1113. The telescopic column 1112 then retracts into the outer tube 1111. The spring 1113 stores elastic potential energy, forming a buffer reaction force that slows the rotation speed and reduces the impact peak. After unloading, the spring 1113 recovers its deformation, pushing the telescopic column 1112 back to its original position. The magnetic block re-attracts the frame 131, causing the protective component 13 to automatically return to its initial tilted posture. Therefore, the limiting column 111 is not a rigid lock. The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
