Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, and in particular to an anchoring method for slope reinforcement. Background Technology

[0002] Anchor bolt support is a reinforcement and support method used in surface engineering projects such as slopes and deep foundation pits, as well as in underground chamber construction such as tunnels and mining areas. Anchor bolts, made of metal, wood, polymer, or other materials, are driven into pre-drilled holes in the surface rock or the surrounding rock mass. Utilizing the special structure of the head and body of the bolt, or a supporting plate at the tail, or relying on bonding, the unstable rock mass is combined with the stable rock mass to produce a suspension effect, a composite beam effect, or a reinforcement effect, thus achieving the purpose of support. However, in the current use of slope protection anchor bolts in bridge and tunnel engineering, there are problems such as difficulty in installation during slope protection, and the anchor bolts are prone to falling off during positioning, thus affecting the effectiveness of the slope protection anchor bolts. Furthermore, the existing slope protection anchor bolts have poor stability, and the connection between the anchor bolt and the rock and soil may be weak, leading to detachment.

[0003] Therefore, how to improve the reinforcement effect of slopes is a technical problem that urgently needs to be solved in the existing technology. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an anchoring method for slope reinforcement, which can improve the anchoring effect on the slope, and the anchoring device is not easy to detach during use, thereby further improving the stability of the slope.

[0007] Step 2: Rotate the shaft inside the anchor rod in the forward direction, causing the nut to move along the axial direction of the shaft, thereby causing the reinforcing rod to retract back into the anchor rod and insert the anchor rod into the anchoring point. Rotate the shaft in the reverse direction, causing the nut to move along the axial direction of the shaft, thereby causing the reinforcing rod to extend out of the anchor rod and insert into the slope soil at the anchoring point. The pressure plate is close to the slope soil, and the anti-slip nail is inserted into the slope soil. Then, the reinforcement component is screwed into the slope soil.

[0008] Step 3: Inject cement grout into the anchor rod through the injection port. The cement grout overflows out of the anchor rod through the injection port, thereby filling the gap between the anchor rod and the slope soil.

[0009] Step 4: Pass the chain through several chain holes in sequence, connect multiple shafts through the chain, and then connect several anchoring devices to complete the reinforcement of the slope.

[0010] Furthermore, in step one, the reinforcing mechanism includes a nut and a reinforcing rod fixedly connected to the nut. The nut is sleeved on the rotating shaft and threadedly engaged with the rotating shaft. The rotating shaft can be rotated operably, so that the nut can move along the axial direction of the rotating shaft, thereby driving the reinforcing rod to extend out of the anchor rod and connect with the slope or retract back into the anchor rod.

[0011] The anchor rod includes a rod body, a cover plate at the end of the rod body, and a conical block at the bottom of the rod body. The rod body includes an outer tube and an inner tube inside the outer tube, with a predetermined gap between the inner tube and the outer tube. The rotating shaft is located inside the inner tube, and its two ends are rotatably supported by the cover plate and the conical block. The side walls of the inner tube and the outer tube are respectively provided with a connecting hole I and a connecting hole II that mate with the reinforcing rod. The reinforcing rod passes through the connecting hole I and is located inside the connecting hole II or inside the gap and can be driven to extend out of the connecting hole II for connection with the slope.

[0012] Furthermore, based on steps one and two, the reinforcing mechanism comprises several groups, which are evenly arranged along the axial direction of the rotating shaft. The nut includes nut I and nut II, and the reinforcing rod includes several reinforcing rods I fixedly connected to nut I and several reinforcing rods II fixedly connected to nut II. The reinforcing rod I is inclined upward relative to the rotating shaft, and the reinforcing rod II is inclined downward relative to the rotating shaft. Nut I and nut II can be driven to move in opposite directions or in opposite directions along the axial direction of the rotating shaft, which is used to drive the reinforcing rods I and II to retract into the outer tube or extend out of the connecting hole II to connect with the slope.

[0013] Furthermore, the rotating shaft is provided with threaded sections I and II with opposite directions of rotation at positions corresponding to the nuts I and II, and the nuts I and II are respectively provided with internal threads that mate with the threaded sections I and II;

[0014] The reinforcing mechanism further includes slider I and slider II. Slider I is sleeved on the rotating shaft and fixedly connected to the lower end of nut I.

The limiting ring I is disposed at the end of the threaded segment I, the limiting ring II is disposed between the slider I and the slider II, and the limiting ring III is disposed at the bottom of the threaded segment II.

[0016] Furthermore, the reinforcing mechanism also includes spring assemblies, which are correspondingly disposed on several reinforcing rods I and several reinforcing rods II. Each spring assembly includes a spring and a fixing block. The fixing block is disposed on the reinforcing rods I and II respectively. The spring is sleeved on the reinforcing rods I and II respectively, with one end of the spring fixedly connected to the fixing block and the other end of the spring fixedly connected to the inner wall of the inner tube.

[0017] Furthermore, in step three, the outer pipe is provided with a plurality of grouting ports, the grouting ports are in communication with the gap, and the cover plate is provided with an injection port in communication with the gap;

[0018] Several annular grooves are also formed on the outer wall of the outer tube.

[0019] Furthermore, in step two, the pressure plate is disposed on the outer circumference of the end of the outer tube, and the plurality of anti-slip nails are evenly distributed on the inner side of the pressure plate.

[0020] Furthermore, in step two, the reinforcing components are in several groups, and the several groups of reinforcing components are evenly distributed along the circumferential direction of the inner side of the pressure plate. The reinforcing components include screws and helical rods fixedly connected to the screws, and the screws are threadedly connected to the pressure plate.

[0021] Furthermore, in step four, the anchor rod also includes a limiting block I, a limiting block II, and a tightening part. The limiting block I is sleeved on the rotating shaft and located inside the cover plate. The cover plate has a through hole that mates with the rotating shaft.

[0022] The beneficial effects of the present invention are as follows: The anchoring method for slope reinforcement of the present invention, by setting a reinforcing mechanism, when the anchor rod is inserted into the slope soil, the nut is moved along the axial direction of the rotating shaft by rotating the shaft, thereby driving the reinforcing rod to be inserted into the slope soil.

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

[0033] Step 1: According to the construction requirements, determine the anchoring points of the slope, assemble the anchor rods, pivot 7 and reinforcing mechanism to form an anchoring device, and place several anchoring devices at the anchoring points; according to the construction requirements, determine the anchoring positions of the slope and complete the assembly of the anchoring devices.

[0034] Step 2: Rotate the shaft 7 inside the anchor rod in the forward direction, causing the nut to move axially along the shaft 7, thereby causing the reinforcing rod to retract back into the anchor rod, inserting the anchor rod into the anchoring point. Rotate the shaft 7 in the reverse direction, causing the nut to move axially along the shaft 7, thereby causing the reinforcing rod to extend out of the anchor rod and insert into the slope soil at the anchoring point. The pressure plate 2 is pressed tightly against the slope soil, and the anti-slip nail 9 is inserted into the slope soil. Then, the reinforcement component is spirally inserted into the slope soil. After the anchor rod is inserted into the slope soil, rotate the shaft 7 so that the reinforcing rod extends out of the anchor rod and inserts into the slope soil, thereby improving the connection strength between the anchor rod and the soil, preventing the anchor rod from falling off, and also distributing the force, further improving the anchoring effect on the slope. Then, the pressure plate 2 is pressed tightly against the soil, and the anti-slip nail 9 is installed to further improve the connection strength between the anchor rod and the slope.

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

[0036] Step 4: Pass the chain sequentially through several chain holes 15, connecting multiple rotating shafts 7 together to connect several anchoring devices, thus completing the slope reinforcement. By connecting several anchoring devices into one unit 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 could cause slope protection failure.

[0037] In this embodiment, in step one, the reinforcing mechanism includes a nut and a reinforcing rod fixedly connected to the nut. The nut is sleeved on the rotating shaft 7 and threadedly engaged with the rotating shaft 7. The rotating shaft 7 can be rotated, allowing the nut to move axially along the rotating shaft 7, thereby causing the reinforcing rod to extend out of the anchor rod and connect with the slope or retract back into the anchor rod. The reinforcing mechanism can be in several groups and evenly arranged along the axial direction of the rotating shaft 7. The rotating shaft 7 is rotatably disposed inside the anchor rod, and the nut is threadedly engaged with the rotating shaft 7. By rotating the rotating shaft 7 forward or backward, the nut is driven to move axially along the rotating shaft 7, thereby causing 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, thus improving the stability of the slope anchoring. Compared with the prior art, it can significantly reduce the probability of the anchor rod separating from the slope soil and improve the reinforcement effect of the slope. Compared with the prior art, the overall structure is simpler and the reinforcement effect of the slope is better.

[0038] The anchor rod includes a rod body, a cover plate 13 disposed at the end of the rod body, and a conical block 6 disposed at the bottom of the rod body. The rod body includes an outer tube 1 and an inner tube 8 disposed within the outer tube 1. A predetermined gap is formed between the inner tube 8 and the outer tube 1. The rotating shaft 7 is disposed within the inner tube 8, and both ends of the rotating shaft 7 are rotatably supported by 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 within the connecting hole II or within the gap and can be driven to extend 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 outer tube 1 are hollow tubular structures with openings at both ends; the inner tube 8 and outer tube 1 are rectangular tubular structures; and the cover plate 13 and the conical block 6 are respectively located at the upper and lower ends of the rod (relative to the top and bottom of the rod). Figure 1(Up and down direction), the inner tube 8 is smaller than 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 grout can flow in the gap. The rotating shaft 7 is set inside the inner tube 8. At the same time, 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 it is necessary to connect the reinforcing rod to the slope soil, the rotating shaft 7 is rotated to drive the reinforcing rod to extend out of the connecting hole II and insert into the slope soil.

[0040] In this embodiment, based on steps one and two, the reinforcing mechanism consists of several groups, which are evenly arranged along the axial direction of the rotating shaft 7. The nut includes nut I16 and nut II22. 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 rods I5 are inclined upward relative to the rotating shaft 7, and the reinforcing rods II21 are inclined downward relative to the rotating shaft 7. Nuts I16 and nut II22 can be driven to move in opposite directions or away from each other along the axial direction of the rotating shaft 7, which is used to drive the reinforcing rods I5 and 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 rod includes at least two reinforcing rods I5 and at least two reinforcing rods II21, with the top and bottom positioned relative to each other. Figure 1 Nuts I16 and II22 are symmetrically arranged in the vertical direction. When reinforcing rods I5 and II21 extend out of the anchor and insert into the slope soil, the reinforcing rods I5 and II21 on the same side of nuts I16 and II22 form a V-shaped structure, which can form a two-way locking, further improving the connection strength between the anchor and the slope. It can bear the force from multiple directions and prevent the anchor from falling off. At the same time, nuts I16 and II22 are shaped like truncated pyramids. One end of reinforcing rods I5 and II21 is respectively provided with inclined surfaces that connect with nuts I16 and II22, thereby increasing the connection area between reinforcing rods I5 and II21 and nuts I16 and II22, and improving the connection strength between reinforcing rods I5 and II21 and nuts I16 and II22 respectively.

[0042] In this embodiment, the rotating shaft 7 is provided with threaded segments I and II with opposite directions of rotation, corresponding to the positions of nuts I16 and II22. Nuts I16 and II22 are respectively provided with internal threads that mate with threaded segments I and II. The rotating shaft 7 is provided with several sets of threaded segments corresponding to the positions of several sets of reinforcing mechanisms. Specifically, corresponding to the positions of nuts I16 and II22, threaded segments I and II have opposite directions of rotation. When the rotating shaft 7 rotates, it drives nuts I16 and II22 to move towards or away from each other along the axial direction of the rotating shaft 7. When nuts I16 and II22 move towards each other, reinforcing rods I5 and II21 retract into the inner tube 1. When nuts I16 and II22 move away from each other, reinforcing rods I5 and II21 extend out of the outer tube 1 and insert into the slope soil.

[0043] The reinforcing mechanism further includes slider I 17 and slider II 23. Slider I 17 is sleeved on the rotating shaft 7 and fixedly connected to the lower end of nut I 16. Slider II 23 is sleeved on the rotating shaft 7 and fixedly connected to the upper end of nut II 22. Slider I 17 and slider II 23 are arranged opposite to each other. (Up and down are relative to each other.) Figure 2 In the vertical direction, sliders I17 and II23 are rectangular structures, and sliders I17 and II23 slide in contact with the inner wall of the inner tube 8. By setting sliders I17 and II23, the rotating shaft 7 can be supported and the radial limit of the rotating shaft 7 can be set to prevent the rotating shaft 7 from deviating during rotation.

[0044] In this embodiment, the reinforcing mechanism further includes a limiting component, which includes a limiting ring I18, a limiting ring II25, and a limiting ring III24 sleeved on the rotating shaft 7. The limiting ring I18 is disposed at the end of the threaded segment I, the limiting ring II25 is disposed between the slider I17 and the slider II23, and the limiting ring III24 is disposed at the bottom of the threaded segment II. The limiting ring I18 is disposed above the nut I16 and is used to limit the upward movement distance of the nut I16. The limiting ring III24 is disposed below the nut II22 and is used to limit the downward movement distance of the nut II22. The limiting ring II25 is used to limit the maximum distance that the nuts I16 and II22 move towards each other.

[0045] In this embodiment, the reinforcing mechanism further includes spring assemblies, which are correspondingly disposed on several reinforcing rods I5 and II21. Each spring assembly includes a spring 19 and a fixing block 20. 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 fixedly connected to the inner wall of the inner tube 8. By providing the spring 19, when the nuts I16 and II22 move in opposite directions, the spring 19 is compressed. When the nuts I16 and II22 move in opposite directions, the spring 19, under the action of elastic force, applies force to the reinforcing rods I5 and II21, making it easier for the reinforcing rods I5 and II21 to retract inside the outer tube 1.

[0046] In this embodiment, in step three, the outer pipe 1 is provided with a plurality of grouting ports 4, which are connected to the gap. The cover plate 13 is provided with a filling port 12 that is connected to the gap. The filling port 12 on the cover plate 13 facilitates the injection of grout into the gap through the filling port 12. The injected grout flows into the gap and flows out of the outer pipe 1 through the grouting port 4, seeping into the slope soil, thereby reinforcing the slope soil and further improving the reinforcement effect of the anchoring device on the slope.

[0047] Several annular grooves 3 are also provided on the outer wall of the outer pipe 1. By setting the annular grooves 3, the contact area between the outer pipe 1 and the slope soil can be increased, thereby improving the connection effect between the anchor and the slope.

[0048] In this embodiment, in step two, the pressure plate 2 is disposed 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 pressure plate 2. The anti-slip studs 9 are relative to... Figure 1 The anchor rod is positioned at the bottom of the pressure plate 2 in the vertical direction. The pressure plate 2 is positioned on the outer circumference of the upper part of the outer pipe 1. By setting anti-slip nails 9, the connection effect between the anchor rod and the slope soil can be increased.

[0049] In this embodiment, in step two, the reinforcement components are in several groups, evenly distributed along the circumferential direction of the inner side of the pressure plate 2. Each reinforcement component includes a screw 10 and a spiral rod 11 fixedly connected to the screw 10. The screw 10 is threadedly connected to the pressure plate 2. The inner side is the side closest to the slope soil. The pressure plate 2 has several threaded holes that mate with the screw 10. By screwing the screw 10 into the pressure plate 2, the spiral rod 11 can be rotated and inserted into the slope soil, thereby further improving the connection strength between the anchor and the slope.

[0050] In this embodiment, in step four, the anchor rod further includes a limiting block I 27, a limiting block II 26, and a tightening part 14. The limiting block I 27 is sleeved on the rotating shaft 7 and located inside the cover plate 13. The cover plate 13 has 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 limiting block II 26 is sleeved on the rotating shaft 7 and located between the tightening part 14 and the cover plate 13. The tightening part 14 has a chain hole 15.

[0051] Specifically, the limiting block I 27 is set on the inner side of the cover plate 13 to limit the rotating shaft 7 and prevent it from coming out. By setting the limiting block II 26, when the rotating shaft 7 is rotated by 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 column structure, which is convenient for users to operate. At the same time, through the chain hole 15, several anchor rods can be connected into one piece by a chain through the chain hole 15 during use, which can play a role in distributing the force and further improving the anchoring effect.

[0052] The anchoring method for slope reinforcement of the present invention assembles the rotating shaft 7, anchor rods, and reinforcing mechanism into one unit. Rotating the rotating shaft 7 causes nuts I16 and II22 to move in opposite directions along the axial direction of the rotating shaft 7. Under the restoring force of the spring 19, reinforcing rods I5 and II21 retract inside the outer tube 1, inserting the conical block 6 into the slope body until the entire outer tube 1 is inserted into the slope body. Rotating the rotating shaft 7 via the tightening part 14 causes nuts I16 and II22 to move in opposite directions along the axial direction of the rotating shaft 7, causing reinforcing rods I5 and II21 to retract 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 nail 9 is inserted into the slope surface, the spiral rod 11 is rotated and inserted into the slope surface, and cement grout is injected into the gap between the inner tube 8 and the outer tube 7 through the injection port 12. The cement grout 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 anchoring device in sequence to realize the connection of several anchoring devices and complete the reinforcement of the slope.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
