Rods are made of metal, wood, polymer or other materials and driven into pre-drilled holes in the surface rock or the rock surrounding the chamber. The special structure of the head and rod body, or the tail support plate, or the bonding effect is used to combine dangerous rocks with stable rock masses to produce a suspension effect, a composite beam effect, and a reinforcement effect, so as to achieve the purpose of support. However, in the use of existing slope anchor rods for bridge and tunnel projects, there are problems such as the anchor rods are difficult to install during the slope protection process of bridge and tunnel projects, and the slope anchor rods are easy to fall off during the positioning process, thereby affecting the use effect of the slope anchor rods.

[0032] like Figure 1-6 As shown: The anchoring method for slope reinforcement of this embodiment includes the following steps:

[0033] Step 1: According to the construction requirements, determine the anchoring position of the slope, assemble the anchor rod, rotating shaft 7 and reinforcement mechanism to form an anchoring device, and place several anchoring devices at the anchoring position; according to the construction requirements, determine the anchoring position of the slope and complete the assembly of the anchoring device.

[0034] The second step is to rotate the shaft 7 arranged in the anchor rod forward, drive the nut to move along the axial direction of the shaft 7, thereby driving the reinforcing rod to retract into the anchor rod and insert the anchor rod into the position to be anchored. The shaft 7 is rotated in the reverse direction to drive the nut to move along the axial direction of the shaft 7, thereby driving the reinforcing rod to extend the anchor rod and insert it into the slope soil at the position to be anchored. The pressure plate 2 is close to the slope soil, and the anti-slip nail 9 is inserted into the slope soil. Then, the reinforcement assembly is spirally inserted into the slope soil. After the anchor rod is inserted into the slope soil, the shaft 7 is rotated so that the reinforcing rod extends out of the anchor rod and is inserted into the slope soil, thereby improving the connection strength between the anchor rod and the soil and preventing the anchor rod from falling off. At the same time, it can disperse the force and further improve the anchoring effect of the slope. Then, the pressure plate 2 is pressed against the soil and anti-slip nails 9 are set to further improve the connection strength between the anchor rod and the slope.

[0035] Step 3: Inject cement slurry into the anchor rod through the filling port 12. The cement slurry overflows out of the anchor rod through the grouting port 4, thereby filling the gap between the anchor rod and the slope soil. Injecting cement slurry into the anchor rod through the filling port 12 can reinforce the slope soil around the anchor rod, further improving the anchoring effect of the slope.

[0036] Step 4: Insert the chain through the chain holes 15 in sequence, connecting the multiple shafts 7 through the chain, thereby connecting the multiple anchoring devices and completing the slope reinforcement. By connecting the multiple anchoring devices together through the chain, when subjected to external forces, the force can be transmitted through the chain, thereby dispersing the force and avoiding localized force concentration that may cause slope protection failure.

[0037] The nut is threadably engaged with the shaft 7 and the reinforcing rod is fixedly connected to the nut. The nut is sleeved on the shaft 7 and is threadably engaged with the shaft 7. The shaft 7 can be rotated so that the nut can move along the axial direction of the shaft 7, thereby driving the reinforcing rod to extend out of the anchor rod and connect with the slope or retract into the anchor rod; the reinforcing mechanism can be a plurality of groups and evenly arranged along the axial direction of the shaft 7. The shaft 7 is rotatably arranged in the anchor rod, and the nut is threadably engaged with the shaft 7. The forward or reverse rotation of the shaft 7 drives the nut to move along the axial direction of the shaft 7, thereby driving the reinforcing rod to retract back into the anchor rod or extend out of the anchor rod and insert into the slope soil, thereby improving the connection strength between the anchor rod and the slope soil, so as to improve the stability of the slope anchoring. Compared with the existing technology, the probability of the anchor rod being separated from the slope soil can be greatly reduced, and the reinforcement effect on the slope can be improved. Compared with the existing technology, the overall structure is simple and the reinforcement effect on the slope is good.

[0038] The anchor rod includes a rod body, a cover plate 13 arranged at the end of the rod body and a conical block 6 arranged at the bottom of the rod body. The rod body includes an outer tube 1 and an inner tube 8 arranged in the outer tube 1. A set gap is formed between the inner tube 8 and the outer tube 1. The rotating shaft 7 is arranged in the inner tube 8 and the two ends of the rotating shaft 7 are rotatably supported on the cover plate 13 and the conical block 6. The side walls of the inner tube 8 and the outer tube 1 are respectively provided with a connecting hole I and a connecting hole II that cooperate with the reinforcing rod. The reinforcing rod passes through the connecting hole I and is located in the connecting hole II or in the gap and can be driven out of the connecting hole II for connection with the slope.

[0039] Specifically, the conical block 6 facilitates the insertion of the anchor rod into the soil. The inner tube 8 and the outer tube 1 are hollow tubular structures with openings at both ends. The inner tube 8 and the outer tube 1 are rectangular tubular structures. The cover plate 13 and the conical block 6 are respectively arranged at the upper end and the lower end of the rod body (relative to the Figure 1In the vertical direction), the size of the inner tube 8 is smaller than that of the outer tube 1, so that a set gap is formed between the outer wall of the inner tube 8 and the inner wall of the outer tube 1, that is, the gap is generally large enough to ensure that the slurry can flow in the gap. The rotating shaft 7 is arranged in the inner tube 8, and the reinforcing rod extends out of the inner tube 8 through the connecting hole I and is located in the gap or in the connecting hole II. When the reinforcing rod needs to be connected to the slope soil, the rotating shaft 7 is rotated to drive the reinforcing rod to extend out of the connecting hole II and be inserted into the slope soil.

[0040] In this embodiment, based on step one and in step two, the reinforcing mechanism is composed of several groups, and the several groups of reinforcing mechanisms are evenly arranged along the axial direction of the rotating shaft 7. The nut includes nut I16 and nut II22, and the reinforcing rod includes several reinforcing rods I5 fixedly connected to nut I16 and several reinforcing rods II21 fixedly connected to nut II22. The reinforcing rod I5 is arranged obliquely upward relative to the rotating shaft 7, and the reinforcing rod II21 is arranged obliquely downward relative to the rotating shaft 7. The nut I16 and the nut II22 can be driven to move toward or away from each other along the axial direction of the rotating shaft 7, so as to drive the reinforcing rod I5 and the reinforcing rod II21 to retract into the outer tube 1 or extend out of the connecting hole II to connect with the slope.

[0041] Specifically, such as Figure 2 As shown, the reinforcing rods include at least two reinforcing rods I5 and at least two reinforcing rods II21, the upper and lower parts of which are relative to each other. Figure 1 In the upper and lower directions, nuts I16 and nuts II22 are symmetrically arranged, so that when the reinforcing rods I5 and II21 extend out of the anchor rods and are inserted into the slope soil, the reinforcing rods I5 and II21 located on the same side of nuts I16 and II22 form a V-shaped structure, thereby forming a two-way locking, which can further improve the connection strength between the anchor rod and the slope, and can bear forces from multiple directions to prevent the anchor rod from falling off. At the same time, the nuts I16 and II22 are in the shape of a quadrangular pyramid, and one end of the reinforcing rods I5 and II21 is respectively provided with an inclined surface connected to the nuts I16 and II22, thereby increasing the connection area of ​​the reinforcing rods I5 and II21 with the nuts I16 and II22, and improving the connection strength of the reinforcing rods I5 and II21 with the nuts I16 and II22 respectively.

[0042] In this embodiment, the positions on the rotating shaft 7 corresponding to the nut I16 and the nut II22 are provided with thread segments I and thread segments II with opposite rotation directions, and the nut I16 and the nut II22 are respectively provided with internal threads that cooperate with the thread segments I and thread segments II; the positions on the rotating shaft 7 corresponding to the plurality of reinforcing mechanisms are provided with several groups of thread segments, specifically, corresponding to the positions of the nut I16 and the nut II22, the thread segments I and the thread segments II have opposite rotation directions. When the rotating shaft 7 rotates, the nut I16 and the nut II22 are driven to move toward or away from each other along the axial direction of the rotating shaft 7. When the nut I16 and the nut II22 move toward each other, the reinforcing rod I5 and the reinforcing rod II21 are contracted inside the outer tube 1. When the nut I16 and the nut II22 move away from each other, the reinforcing rod I5 and the reinforcing rod II21 extend out of the outer tube 1 and are inserted into the slope soil.

[0043] The reinforcing mechanism further includes a slider I 17 and a slider II 23. The slider I 17 is sleeved on the rotating shaft 7 and fixedly connected to the lower end of the nut I 16. The slider II 23 is sleeved on the rotating shaft 7 and fixedly connected to the upper end of the nut II 22. The slider I 17 and the slider II 23 are arranged relative to each other. Figure 2 In the up and down directions, slider I 17 and slider II 23 are rectangular structures, and slider I 17 and slider II 23 slide with the inner wall of the inner tube 8. By arranging slider I 17 and slider II 23, support can be formed for the rotating shaft 7, and the radial position of the rotating shaft 7 can be limited to prevent the rotating shaft 7 from offset during rotation.

[0044] In this embodiment, the reinforcement mechanism further includes a limiting assembly, which includes a limiting ring I 18, a limiting ring II 25, and a limiting ring III 24, which are sleeved on the rotating shaft 7. The limiting ring I 18 is disposed at the end of the threaded segment I, the limiting ring II 25 is disposed between the slider I 17 and the slider II 23, and the limiting ring III 24 is disposed at the bottom of the threaded segment II. The limiting ring I 18 is disposed above the nut I 16 and is used to limit the upward movement distance of the nut I 16. The limiting ring III 24 is disposed below the nut II 22 and is used to limit the downward movement distance of the nut II 22. The limiting ring II 25 is used to limit the maximum distance that the nuts I 16 and II 22 can move toward each other.

[0045] In this embodiment, the reinforcing mechanism further includes a spring assembly, which is disposed one-to-one on a plurality of reinforcing rods I5 and a plurality of reinforcing rods II21. The spring assembly includes a spring 19 and a fixing block 20, wherein the fixing block 20 is disposed on each of the reinforcing rods I5 and II21. The spring 19 is sleeved on each of the reinforcing rods I5 and II21, with one end of the spring 19 fixedly connected to the fixing block 20 and the other end of the spring 19 fixedly connected to the inner wall of the inner tube 8. By providing the spring 19, when the nut I16 and the nut II22 move away from each other, the spring 19 is compressed. When the nut I16 and the nut II22 move toward each other, the spring 19, under the action of the elastic force, applies a force to the reinforcing rods I5 and II21, making it easier for the reinforcing rods I5 and II21 to retract within the interior of the outer tube 1.

[0046] In this embodiment, in step three, a plurality of grouting ports 4 are provided on the outer tube 1, and the grouting ports 4 are communicated with the gap. A filling port 12 communicated with the gap is provided on the cover plate 13; the filling port 12 is provided on the cover plate 13 to facilitate the filling of slurry into the gap through the filling port 12. The filled slurry flows into the gap and flows out of the outer tube 1 through the grouting port 4, and penetrates into the slope soil, thereby reinforcing the slope soil and further improving the reinforcement effect of the anchoring device on the slope.

[0047] The outer wall of the outer tube 1 is also provided with a plurality of annular grooves 3. By providing the annular grooves 3, the contact area between the outer tube 1 and the slope soil can be increased, thereby improving the connection effect between the anchor rod and the slope.

[0048] In this embodiment, in step 2, the pressing plate 2 is arranged on the outer circumference of the end of the outer tube 1, and the plurality of anti-slip studs 9 are evenly distributed on the inner side of the pressing plate 2. Figure 1 The upper and lower directions are arranged at the lower part of the pressure plate 2, and the pressure plate 2 is arranged on the outer circumference of the upper part of the outer tube 1. By arranging the anti-slip nails 9, the connection effect between the anchor rod and the slope soil can be increased.

[0049] In this embodiment, in step 2, the reinforcement components are arranged in several groups, evenly distributed along the circumference of the inner side of the pressure plate 2. The reinforcement components include screws 10 and screw rods 11 fixedly connected to the screws 10. The screws 10 are threadedly connected to the pressure plate 2. The inner side is the side close to the slope soil. The pressure plate 2 is provided with several threaded holes that cooperate with the screws 10. By screwing the screws 10 into the pressure plate 2, the screw rods 11 can be rotated and inserted into the slope soil, thereby further improving the connection strength between the anchor rod and the slope.

[0050] In this embodiment, in step four, the anchor rod also includes a limit block I27, a limit block II26 and a tightening part 14, the limit block I27 is sleeved on the rotating shaft 7 and is located on the inner side of the cover plate 13, the cover plate 13 is provided with a through hole that cooperates with the rotating shaft 7, the rotating shaft 7 extends out of the through hole and is fixedly connected to the tightening part 14, the limit block II26 is sleeved on the rotating shaft 7 and is located between the tightening part 14 and the cover plate 13, and the tightening part 14 is provided with a chain hole 15.

[0051] Specifically, the limit block I27 is arranged on the inner side of the cover plate 13, and is used to limit the rotating shaft 7 to prevent the rotating shaft 7 from falling out. By setting the limit block II26, when the rotating shaft 7 is rotated through the tightening part 14, it can play a role in preventing loosening and tightening, and can reduce the force on the cover plate 13. The tightening part 14 is generally a polygonal columnar structure, which is convenient for users to operate. At the same time, through the chain hole 15, when in use, a chain can be used to connect several anchor rods into one through the chain hole 15, which can disperse the force and further improve the anchoring effect.

[0052] The anchoring method for slope reinforcement of the present invention is to assemble the rotating shaft 7, the anchor rod and the reinforcement mechanism into one body, rotate the rotating shaft 7, drive the nut I16 and the nut II22 to move toward each other along the axial direction of the rotating shaft 7, under the action of the restoring force of the spring 19, the reinforcing rod I5 and the reinforcing rod II21 are contracted inside the outer tube 1, and the conical block 6 is inserted into the slope until the entire outer tube 1 is inserted into the slope, and rotate the rotating shaft 7 by the tightening part 14, drive the nut I16 and the nut II22 to move away from each other along the axial direction of the rotating shaft 7, so that the reinforcing rod I5 and the reinforcing rod II21 are contracted inside the outer tube 1. Rod II 21 extends out of the outer tube 1 and is inserted into the slope soil around the anchor rod. At this time, the pressure plate is close to the ground, the anti-slip nails 9 are inserted into the slope surface, and the spiral rod 11 is rotated and inserted into the slope surface. Cement slurry is injected into the gap between the inner tube 8 and the outer tube 7 through the filling port 12. The cement slurry overflows into the soil around the anchor rod through the grouting port 4, thereby filling the gap between the outer tube 1 and the soil. The chain (not shown in the figure) is passed through the chain hole 15 of the anchor device in sequence to realize the connection of several anchor devices and complete the reinforcement of the slope.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
