Description

Technical Field

[0001] This invention relates to the field of slope protection technology, and in particular to a rock slope support and reinforcement device. Background Technology

[0002] Rock slopes are slopes composed of rocks, commonly found in mountainous areas, river valleys and other geological environments. Due to natural factors such as weathering and rainfall, rock slopes are prone to geological disasters such as collapses and landslides, threatening human life and property safety. Currently, the protection and support of rock slopes are usually achieved by using support anchors and support nets.

[0003] Although the current support structure is simple, it has low reliability. The support anchors are arranged perpendicularly to the rock strata, which makes the support method prone to overall slippage. Furthermore, after the anchors are inserted into the strata, the contact between them and the rock is insufficient, resulting in low friction. Although concrete is poured for reinforcement, if the surface of the anchors is not sufficiently roughened, the anchors can easily be pulled out of the concrete when the slope vibrates or a landslide occurs. This renders the entire support structure ineffective and unable to effectively support the rock slope. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rock slope support and reinforcement device, comprising a protective component, including a barrier net, support legs disposed at the ends of the barrier net, and a support plate hinged to the ends of the support legs; and,

[0006] The reinforcement assembly includes a fixed post fixed to the end of the barrier net, a push ring sleeved on the outer wall of the fixed post, a first reinforcement ring and a second reinforcement ring sleeved on the outer wall of the fixed post, a shaped block hinged to the inner wall of the second reinforcement ring, a push rod hinged to the end of the shaped block, and a limiting post disposed on the outer wall of the push rod.

[0007] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, wherein: a conical column and a fixing ring are sleeved at the end of the fixing column, a groove is provided on the outer wall of the push ring, and a first elastic element is provided on the outer wall of the push ring.

[0008] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, wherein: a first limiting rod is hinged to the inner wall of the first reinforcement ring, a sliding groove is provided at the end of the first limiting rod, a first movable rod is hinged to the end face of the first limiting rod, and the other end of the first movable rod is hinged to the inner wall of the groove.

[0009] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, the second reinforcement ring has a second limiting rod hinged to its inner wall, the end of the second limiting rod has a through groove, the outer wall of the second limiting rod has a placement groove, and the end of the through groove is hinged to the fixing block fixed to the outer wall of the fixing column.

[0010] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, the inner wall of the second limiting rod is provided with a receiving cavity, the outer wall of the second limiting rod is hinged with a second movable rod, and the other end of the second movable rod extends to the inner wall of the groove and slides therewith.

[0011] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, wherein: the end of the irregular block is provided with a bend and an end corner, the end of the irregular block is hinged to a hinge block, the outer wall of the bend is hinged to a hinge rod, and the end corner is hinged to the inner wall of the through groove.

[0012] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, wherein: the end of the push rod is hinged to the hinge rod, and the other end of the push rod extends to the inner wall of the second limiting rod and moves inside the accommodating cavity.

[0013] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, the outer wall of the push rod is provided with a connecting block, and the end face of the connecting block is provided with a sliding column.

[0014] As a preferred embodiment of the rock slope support and reinforcement device of the present invention, wherein: the end of the limiting column is hinged to the inner wall of the placement groove, the end of the limiting column is provided with a connecting rod, and the end face of the connecting rod is provided with a movement groove.

[0015] In a preferred embodiment of the rock slope support and reinforcement device of the present invention, the push rod cooperates with the limiting column, the connecting block is movably disposed on the inner wall of the connecting rod, and the end of the sliding column extends to the inner wall of the motion groove and slides therewith.

[0016] The beneficial effects of this invention are as follows: This invention uses a support plate to fix the retaining net onto the rock slope, which can adjust the overturning angle of the net. At the same time, the support plate rests on the ground and can bear part of the force in the event of a landslide, preventing the reinforcement components from easily detaching from the rock layer. In addition, the first and second limiting rods open outward after being inserted into the rock layer, increasing the contact with the rock and increasing the bonding strength with the concrete after pouring. This prevents the reinforcement components from being easily pulled out of the concrete under vibration or other conditions, thus improving the support capacity. Attached Figure Description

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a rock slope support and reinforcement device.

[0028] Specifically, the protective component 100 includes a barrier net 101, support legs 102 disposed at the ends of the barrier net 101, and a support plate 103 hinged to the ends of the support legs 102; and,

[0029] The reinforcement component 200 includes a fixed post 201 fixed to the end of the barrier net 101, a push ring 202 sleeved on the outer wall of the fixed post 201, a first reinforcement ring 203 and a second reinforcement ring 204 sleeved on the outer wall of the fixed post 201, a shaped block 205 hinged to the inner wall of the second reinforcement ring 204, a push rod 206 hinged to the end of the shaped block 205, and a limiting post 207 disposed on the outer wall of the push rod 206.

[0030] The barrier net 101 covers the surface of the rock slope. The support foot 102 at the bottom of the barrier net 101 is hinged to the top of the support plate 103, which can adjust the angle of the barrier net 101. The support plate 103 is supported on the ground. When the slope landslides or other situations occur, in addition to the reinforcement component 200 bearing the force, the support plate 103 will also share part of the force of the reinforcement component 200, so that the reinforcement component 200 will not be easily shaken out of the rock layer.

[0031] The entire reinforcement component 200 is inserted into the hole drilled in the rock slope. The tail of the fixing column 201 is fixed to the steel plate connection of the netting 101. The fixing column 201 is inclined downward into the hole to avoid the problem that it is easy to fall out of the rock layer if inserted straight. When the landslide impacts the netting 101, the inclined setting of the fixing column 201 makes the landslide need to impact the netting 101 obliquely upward in order to successfully knock the netting 101 off the slope.

[0032] The push ring 202 is fitted onto the outside of the fixed column 201. When the fixed column 201 is inserted into the hole, the push ring 202 pushes forward, causing the first limiting rod 203a and the second limiting rod 204a on the outer walls of the first reinforcing ring 203 and the second reinforcing ring 204 to move and open within the hole, increasing the friction with the rock layer and preventing the fixed column 201 from being easily pulled out of the rock layer. When the first limiting rod 203a and the second limiting rod 204a open, the internal irregular block 205 drives the push rod 206 to move, causing the limiting column 207 to open outward. After the limiting column 207 opens outward, the bonding force between it and the poured concrete increases again, improving the overall bonding degree between the fixed column 201 and the concrete and enhancing the support capacity.

[0033] In summary, during use, the reinforcement component 200 is first inserted into the drilled hole in the rock slope. After the reinforcement component 200 extends into the hole, the movement of the push ring 202 drives the first limiting rod 203a and the second limiting rod 204a to move. The outer walls of the first reinforcement ring 203 and the second reinforcement ring 204 open and are locked onto the inner wall of the hole. At the same time as the first limiting rod 203a and the second limiting rod 204a open, the internal push rod 206 moves downward under the action of the irregular block 205, causing the limiting posts 207 on both sides to open outward. Then, concrete is poured inward, and finally, the netting 101 is placed over the reinforcement component 200 to complete the slope support work.

[0034] Example 2

[0035] Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a conical column 201a and a fixing ring 201b are sleeved at the end of the fixing column 201, a groove 202a is provided on the outer wall of the push ring 202, and a first elastic element 202b is provided on the outer wall of the push ring 202.

[0037] The conical column 201a, which is fitted at the top of the fixed column 201, can push away the soil debris remaining in the hole when it is inserted into the hole. The fixed ring 201b is fixed at the rear of the fixed column 201. The push ring 202 is fitted near the fixed ring 201b and can slide outside the fixed column 201. Initially, the push ring 202 is close to the fixed ring 201b, and at this time the first elastic element 202b is also in a compressed state.

[0038] Preferably, a first limiting rod 203a is hinged to the inner wall of the first reinforcing ring 203, a sliding groove 203b is provided at the end of the first limiting rod 203a, a first movable rod 203c is hinged to the end face of the first limiting rod 203a, and the other end of the first movable rod 203c is hinged to the inner wall of the groove 202a.

[0039] The first limiting rod 203a array is arranged on the inner wall of the first reinforcing ring 203. A groove 203b is opened on the outer surface of the first limiting rod 203a. The other surface of the first limiting rod 203a is hinged to the first movable rod 203c. The other end of the first movable rod 203c is hinged to the inner wall of the groove 202a opened on the surface of the push ring 202. When the push ring 202 is pushed to move by the first elastic element 202b, the first movable rod 203c pushes the first limiting rod 203a to open outward and fit against the inner wall of the rock stratum.

[0040] The inner wall of the second reinforcing ring 204 is hinged with a second limiting rod 204a. The end of the second limiting rod 204a is provided with a through groove 204a-1, and the outer wall of the second limiting rod 204a is provided with a placement groove 204a-2. The end of the through groove 204a-1 is hinged to the fixing block fixed to the outer wall of the fixing column 201.

[0041] The second reinforcing ring 204 has the same structure as the first reinforcing ring 203, and the second limiting rod 204a has the same structure as the first limiting rod 203a. The only difference is that a groove 203b is opened on the outer surface of the first limiting rod 203a.

[0042] The end of the second limiting rod 204a is provided with a through groove 204a-1. The inner wall of the through groove 204a-1 is hinged to the fixing block on the outer wall of the fixing column 201. Multiple placement grooves 204a-2 are arrayed on the outer walls on both sides of the second limiting rod 204a.

[0043] Preferably, the inner wall of the second limiting rod 204a is provided with a receiving cavity 204b, and the outer wall of the second limiting rod 204a is hinged with a second movable rod 204c, the other end of the second movable rod 204c extending to the inner wall of the slide groove 203b and slidingly engaging with it.

[0044] The accommodating cavity 204b is connected to the end of the placement groove 204a-2 on the outer wall of the second limiting rod 204a. The other end of the second movable rod 204c, which is hinged to the inner wall of the second limiting rod 204a, slides inside the sliding groove 203b. When the push ring 202 pushes the first movable rod 203c to open the outer wall of the first reinforcing ring 203, the other end of the second movable rod 204c slides from one end near the first reinforcing ring 203 to the other end inside the sliding groove 203b of the first limiting rod 203a. At this time, the second limiting rod 204a is pushed by the second movable rod 204c and opens outside the second reinforcing ring 204.

[0045] In summary, during initial use, a cloth bag is fitted over the outside of the reinforcing component 200. At this time, the first limiting rod 203a and the second limiting rod 204a are pressed tightly against the outside of the fixing post 201. The push ring 202 is close to the fixing ring 201b, and the first elastic element 202b is compressed. When the reinforcing component 200 is inserted into the hole in the rock stratum, the cloth bag is pulled out. Without restraint, the first elastic element 202b recovers its deformation, causing the push ring 202 to move closer to the conical post 201a. The first movable rod 203c, hinged in the groove 202a on the outer wall of 202, pushes the first limiting rod 203a outward. At the same time as the first limiting rod 203a opens, the second movable rod 204c, hinged in the inner wall of the second limiting rod 204a, slides in the groove 203b on the outer wall of the first limiting rod 203a and pushes the second limiting rod 204a outward together. The first limiting rod 203a and the second limiting rod 204a are together locked inside the rock cavity, fixing the reinforcement component 200 in the rock stratum.

[0046] Example 3

[0047] Reference Figures 2-5 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0048] Specifically, the irregular block 205 has a bend 205a and an end corner 205b at its end, a hinge block 205c is hinged to the end of the irregular block 205, a hinge rod 205d is hinged to the outer wall of the bend 205a, and the end corner 205b is hinged to the inner wall of the through groove 204a-1.

[0049] Among them, the bend 205a of the irregular block 205 is located at the middle connection position of the end and the end corner 205b, and the end and the end corner 205b are connected perpendicularly. The hinge block 205c is hinged at the end of the irregular block 205. The end position of the hinge block 205c is fixed to the surface of the second reinforcing ring 204. The outer wall of the end corner 205b is hinged to the inner wall of the through groove 204a-1 opened at the end of the second limiting rod 204a.

[0050] The end slot 204a-1 of the second limiting rod 204a is hinged to the fixing block on the surface of the fixing post 201. When the second limiting rod 204a reverses and opens the second reinforcing ring 204, the end of the irregular block 205 is hinged and fixed to the inner wall of the second reinforcing ring 204. The end corner 205b of the irregular block 205 moves together with the second limiting rod 204a as it flips. At this time, the bend angle 205a of the irregular block 205 also moves, flipping from a position far away from the hinge block 205c and at a lower horizontal position to above the hinge block 205c.

[0051] Preferably, the end of the push rod 206 is hinged to the hinge rod 205d, and the other end of the push rod 206 extends to the inner wall of the second limiting rod 204a and moves inside the accommodating cavity 204b. A connecting block 206a is provided on the outer wall of the push rod 206, and a sliding column 206b is provided on the end face of the connecting block 206a.

[0052] Among them, the hinge rod 205d, which is externally hinged to the bend angle 205a of the irregular block 205, is located on both sides of the bend angle 205a. The other end of the hinge rod 205d is hinged to both sides of the end of the push rod 206. The push rod 206 moves inside the second limiting rod 204a. When the second limiting rod 204a flips, the bend angle 205a of the irregular block 205 moves. When the irregular block 205 moves, the bend angle 205a moves from a lower horizontal position to above the hinge block 205c, which drives the hinge rod 205d to move and pulls the push rod 206 outward from inside the second limiting rod 204a.

[0053] The end of the limiting post 207 is hinged to the inner wall of the placement groove 204a-2. A connecting rod 207a is provided at the end of the limiting post 207, and a motion groove 207b is opened on the end face of the connecting rod 207a.

[0054] The end of the limiting post 207 is hinged to the inner wall of the placement groove 204a-2. The limiting post 207 can swing with its end as the hinge point. The connecting rod 207a at the end of the limiting post 207 is hinged to the connecting blocks 206a on both sides of the push rod 206. The sliding post 206b on the surface of the connecting block 206a slides inside the motion groove 207b on the surface of the connecting rod 207a.

[0055] Preferably, the push rod 206 cooperates with the limiting post 207, the connecting block 206a is movably disposed on the inner wall of the connecting rod 207a, and the end of the sliding post 206b extends to the inner wall of the motion groove 207b and slides therewith.

[0056] When the push rod 206 is in its original position, the sliding column 206b is located at the upper end of the motion groove 207b, that is, at the end away from the limiting column 207. When the push rod 206 moves downward, the sliding columns 206b on both sides slide from the upper end of the motion groove 207b to the lower end of the motion groove 207b, causing the limiting column 207 to open to both sides inside the placement groove 204a-2.

[0057] In summary, during use, when the second limiting rod 204a flips outward on the outer wall of the second reinforcing ring 204, the irregular block 205 at the bottom of the second limiting rod 204a rotates along with the flipping of the second limiting rod 204a, causing the hinge angle 205a to rotate, which in turn drives the externally hinged hinge rod 205d to move. The push rod 206, which is hinged at the other end of the hinge rod 205d, moves downward inside the second limiting rod 204a, causing the limiting rod 207 inside the placement groove 204a-2 on the outer wall of the second limiting rod 204a to open outward. At this time, after concrete is poured into the rock stratum, the limiting post 207 on the outer side of the first limiting rod 203a and the second limiting rod 204a opens outward and comes into contact with the concrete, increasing the adhesion with the concrete and avoiding the problem that the fixed post 201 is easily pulled out of the concrete due to insufficient roughness. This improves the support capacity of the reinforcing component 200.
