Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and in particular to an anchor bolt support reinforcement structure and its working method. Background Technology

[0002] Anchor bolt support is an engineering technique that uses anchor bolts installed in the rock and soil mass to reinforce and stabilize the pit wall. The anchor bolts "bind" multiple rock layers into a whole composite beam, preventing the rock from sliding along the bedding plane, avoiding delamination of the rock layers, enhancing the overall strength of the rock layers, and reducing bending strain and stress.

[0003] Chinese invention patent with publication number CN110410123A discloses a new type of high-strength anchor bolt support equipment for coal mines, which is equipped with an inner anchor sleeve. Its radially extended reinforcing structure can be well connected to the inner wall of the borehole. At the same time, the inner anchor sleeve is a circumferential expansion structure, which not only makes it easy to extend into the borehole, but also ensures the integral performance of the inner anchor sleeve and the inner wall of the anchor hole through grouting. Although the anchor bolt support device contacts the pit wall through an extended reinforced structure, its inner anchor sleeve is made of soft material. Before the grout solidifies, the outer anchor bolt needs to be threaded into the soft inner anchor bolt in the anchor hole to provide support. This operation is laborious. Furthermore, since a large number of anchor bolt supports are installed in a single pit wall, the grouting equipment needs to be repeatedly connected to the inner anchor sleeve for grouting. Some anchor bolt supports are installed at higher positions, requiring delicate high-altitude operations for connection and grouting. Increasing the time spent at height increases the risk factor of construction. In summary, the anchor bolt support device in this patent results in a time-consuming and laborious anchoring operation with a certain degree of risk. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a reinforced anchor bolt support structure and working method. By incorporating a piercing section that penetrates deep into the anchor bolt shaft, and by using an oblique opening to expand and deform the anchor bolt shaft, the resistance against the pit wall is strengthened. Simultaneously, the outer packaging of the grouting cylinder is pierced, and the grouting fluid is filled into the deep gaps of the anchor bolt hole through the extrusion force of a push rod. This allows for simultaneous deep grouting of the anchor bolt hole and installation of the anchor bolt shaft, reducing the installation time of the anchor bolt support. To achieve the above objective, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides an anchor bolt support reinforcement structure, comprising: An anchor rod section, including an anchor rod body with an oblique opening at its front end, wherein the anchor rod body is a hollow structure and contains a grout cylinder filled with grouting liquid; A piercing part is provided in the oblique opening. The piercing part includes a cone body. A sharp blade is fixed at the rear end of the cone body. A material conveying channel is opened at the end of the cone body near the sharp blade. A cavity communicating with the material conveying channel is opened inside the cone body. A discharge slot communicating with the cavity is opened on the side surface of the cone body. A reinforcing structure is provided at the end of the anchor rod body away from the oblique opening. The reinforcing structure includes a push rod that extends into the anchor rod body. By driving the push rod, the grout cylinder contacts and is punctured by the sharp edge of the puncture part. The grout in the grout cylinder flows through the material conveying channel, the cavity, and the discharge trough to fill the deep gaps in the anchor bolt hole.

[0005] As a further implementation, the anchor rod body is provided with material penetration holes evenly distributed at one end near the puncture part, and guide strips are evenly fixed on the outer surface of the anchor rod body, with each pair of guide strips corresponding to the position of the material penetration hole.

[0006] As a further implementation, the anchor rod body has a first threaded groove at the end away from the puncture part. The reinforcing structure includes a sleeve that is threadedly connected to the first threaded groove. The sleeve has an integrally formed cylinder inside it. A connecting rod passes through the inner wall of the cylinder. The front end of the connecting rod has an integrally formed threaded rod. The threaded rod is threadedly connected to the push rod. The push rod can slide on the inner wall of the anchor rod body.

[0007] As a further implementation, the cylinder is provided with a plurality of first feed holes, and the sleeve is provided with a plurality of second feed holes. The outlet of the second feed hole is exposed outside the anchor rod body. The grouting liquid enters the second feed hole through the first feed hole by compression and can seep into the gap between the reinforcing structure and the pit wall, as well as the outward gap between the anchor rod body and the pit wall.

[0008] As a further implementation, the sleeve is provided with a first magnetic ring at the end away from the anchor rod body, the first magnetic ring is magnetically attached to a magnetic cap, and a filling mechanism is provided on the first magnetic ring.

[0009] As a further implementation, the packing mechanism includes an air pump, a connecting pipe fixed to the output end of the air pump, a second magnetic ring fixed to the end of the connecting pipe away from the air pump, a transparent hopper fixed to the end of the connecting pipe near the second magnetic ring, a PTFE membrane fixed to the end of the transparent hopper near the air pump, and the second magnetic ring and the first magnetic ring magnetically adsorbed to achieve the connection between the packing mechanism and the reinforcing structure.

[0010] As a further implementation, a second positioning post is fixed on the second magnetic ring, and a positioning hole adapted to the second positioning post is provided on the first magnetic ring.

[0011] As a further implementation, the filling mechanism also includes a first fixed plate and a second fixed plate. A slide rod is fixed between the first fixed plate and the second fixed plate. A slider is sleeved on the slide rod. A long cylinder sleeved on the connecting pipe is integrally formed at the rear end of the slider. A pull plate is integrally formed at the end of the long cylinder away from the slider. The pull plate is located at the rear end of the second fixed plate. A circular hole that slides and connects with the long cylinder is opened at the center of the second fixed plate.

[0012] As a further implementation, the slurry cylinder includes an outer packaging and grout filling inside the outer packaging, wherein the outer packaging is a cylindrical polypropylene plastic bag.

[0013] In a second aspect, the present invention provides a method for operating the anchor bolt support reinforcement structure according to the first aspect, comprising the following steps: First, insert the piercing tip into the anchor bolt hole on the borehole wall with the piercing tip facing outward. Then, place the grout cylinder into the anchor bolt body, install the reinforcing structure, and place the anchor bolt body into the anchor bolt hole. Next, push the push rod into the inner wall of the anchor bolt body. The grout cylinder contacts the piercing tip as the push rod is pushed, and the grout cylinder is pierced and enters the cavity through the material conveying channel on the cone. The grout is squeezed out of the cavity by the push rod and squeezed into the outlet trough to fill the depth of the anchor bolt hole and the gap between the gravel. After the grout cylinder is squeezed, the push rod simultaneously drives the anchor bolt body deeper into the anchor bolt hole. The oblique opening contacts the cone, and the cone opens the oblique opening, causing the oblique opening of the anchor bolt body to deform to both sides. The anchor bolt body is stuck in the anchor bolt hole through deformation. As the anchor bolt body is opened, part of the grout in the grout cylinder fills the space between the anchor bolt body and the pit wall through the material penetration hole.

[0014] The beneficial effects of the present invention are as follows: (1) The present invention sets a piercing part that penetrates into the anchor rod part, and expands and deforms the anchor rod part through the oblique opening to enhance the resistance to the pit wall. At the same time, it pierces the outer packaging of the grout cylinder and fills the gap deep in the anchor rod hole with grout through the extrusion force of the push rod. This realizes that the grouting deep in the anchor rod hole and the installation of the anchor rod part are carried out at the same time, reducing the installation time of the anchor rod support. Meanwhile, the solid push rod fills the inner wall of the hollow anchor rod part to play a reinforcing role.

[0015] (2) The present invention connects the anchor rod and the push rod with a reinforced structure, while sealing the space between the anchor rod and the pit wall and forming a unique grout inlet. This enables bidirectional filling from the outside to the inside of the anchor hole, and more thorough filling of the gap between the anchor support and the anchor hole. Furthermore, by setting a guide strip, the bidirectional grout flows more evenly. The guide strip, which can be deformed by external force, and the grout filling between the guide strips and between the guide strips and the pit wall increase the contact area with the pit wall, thereby strengthening the support.

[0016] (3) By setting up a grouting cylinder, the present invention can realize the operation of filling the outer packaging with grout and sealing the injection port on the ground, reducing the time for climbing and making most of the grouting liquid injection realize the grouting operation deep in the anchor hole at the same time as the anchor rod is installed, so that the grouting deep in the anchor hole is more sufficient.

[0017] (4) The present invention uses an air pump to pump the required grout into a transparent silo by setting a filling mechanism. The material can be taken according to the grouting amount. The length of the grouting connection pipe is suitable for high-altitude grouting. At the same time, the pipe does not need to be filled with grout to avoid waste. At the same time, magnetic attraction realizes the connection between the connection pipe and the cylinder, which makes the grouting connection method simple and saves the labor of workers.

[0018] (5) The present invention supports the soft connecting pipe by setting a fixed first fixing plate, a second fixing plate and a sliding rod, and a sliding slider, a pull plate and a long cylinder to support the soft connecting pipe. This enables grouting of anchor bolts installed at high places from the ground, which can reduce or avoid the time spent climbing to high places due to grouting, save time and effort, and improve the safety of anchor bolt installation.

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 2 As shown, an anchor bolt support reinforcement structure includes an anchor bolt section 1, a puncture section 2, a reinforcement structure 4, a filling mechanism 5, and a grout cylinder 6.

[0024] The anchor rod portion 1 includes an anchor rod body 101. The front end of the anchor rod body 101 has an oblique opening 102, and a piercing portion 2 is provided inside the oblique opening 102. Material passage holes 103 are evenly distributed at one end of the anchor rod body 101 near the piercing portion 2. A slurry cylinder 6 is placed on the inner wall of the anchor rod body 101. For example... Figure 3 and Figure 4 As shown, the puncture part 2 includes a cone body 201, a sharp blade 205 fixed at the rear end of the cone body 201, a material conveying channel 204 opened at one end of the cone body 201 near the sharp blade 205, a cavity 202 communicating with the material conveying channel 204 opened inside the cone body 201, and a discharge slot 203 communicating with the cavity 202 opened on the side surface of the cone body 201.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a reinforcing structure 4 is provided at the end of the anchor rod 1 away from the puncture part 2. A first threaded groove 104 is provided at the end of the anchor rod body 101 away from the cone 201. The reinforcing structure 4 includes a sleeve 401 threadedly connected to the first threaded groove 104. The sleeve 401 is threadedly connected to the anchor rod body 101 through a third threaded groove 407 on its inner wall. A coaxial cylinder 402 integrally formed therein is provided in the sleeve 401. A connecting rod 404 passes through the inner wall of the cylinder 402. A threaded rod 405 is integrally formed at the front end of the connecting rod 404. A push rod 403 is threadedly connected to the threaded rod 405. The push rod 403 can slide on the inner wall of the anchor rod body 101. Figure 10 and Figure 11 As shown, a first magnetic ring 413 is provided at the end of the sleeve 401 away from the anchor rod body 101. A magnetic cap 410 is magnetically attracted to the first magnetic ring 413, and a filling mechanism 5 is provided on the first magnetic ring 413.

[0026] like Figure 10 As shown, the magnetic cover 410 has a first positioning post 411 integrally formed on it. The first positioning post 411 and the second positioning post 512 have the same specifications. In this embodiment, after the grouting is completed, the first positioning post 411 is aligned with the positioning hole 412 and the magnetic cover 410 is attracted to the first magnetic ring 413 to seal the cylinder 402, so as to prevent the grouting liquid 602 from flowing out through the cylinder 402.

[0027] In this embodiment, the piercing part 2 with its tip 205 facing outward is first inserted into the anchor bolt hole on the bore wall. The grout cylinder 6 is then placed into the anchor bolt body 101. The threaded rod 405 on the connecting rod 404 contacts the second threaded groove 406 of the push rod 403. The connecting rod 404 and the push rod 403 are installed by rotating them in opposite directions. One end of the third threaded groove 407 on the sleeve 401 faces the push rod 403, and the cylinder 402 is fitted onto the connecting rod 404. The anchor bolt body 101 is then placed into the anchor bolt hole, and the push rod 403 is subsequently pushed in. The inner wall of the anchor rod body 101 is punctured by the push rod 403, which contacts the sharp edge 205. The slurry cylinder 6 is punctured and enters the cavity 202 through the material conveying channel 204 on the cone body 201. The slurry is squeezed out of the cavity 202 by the push rod 403 and squeezed into the discharge slot 203, filling the deep part of the anchor bolt hole and the gap between the gravel. After the slurry cylinder 6 is squeezed, the sleeve 401 can contact the first threaded groove 104 on the anchor rod body 101. At the same time, the push rod 403 drives the anchor rod body 101 to go deeper into the anchor bolt hole (the push rod 403 is wrapped with a sleeve). The silicone rubber layer, through which the push rod 403 is in close contact with the inner wall of the anchor rod body 101 (with strong friction), the oblique opening 102 contacts the cone 201 and the cone 201 expands the oblique opening, causing the oblique opening of the anchor rod body 101 to deform to both sides. The anchor rod body 101 is stuck in the anchor hole through deformation. As the anchor rod body 101 is expanded, part of the grouting liquid 602 in the grout cylinder 6 fills the space between the anchor rod body 101 and the pit wall through the material passage hole 103. The third thread of the sleeve 401... The groove 407 is aligned with the first threaded groove 104 on the anchor rod body 101 and rotated in opposite directions to install the sleeve 401 (at this time, the anchor rod body 101 does not block the first feed hole 408). The sleeve 401 contacts the pit wall, and the connecting rod 404 is rotated to unscrew the threaded rod 405, exposing the inner wall of the cylinder 402. Grouting liquid can be injected through the inner wall of the cylinder 402 through the filling mechanism 5. After the grouting liquid is injected, it can be sealed by magnetic attraction of the magnetic cap 410 to the first magnetic ring 413 to reduce the outflow of undried grouting liquid.

[0028] like Figure 2 As shown, guide strips 3 are uniformly fixed on the outer surface of the anchor rod body 101. Every two guide strips 3 correspond to the position of the material penetration hole 103. In this embodiment, part of the grouting liquid 602 in the grout cylinder 6 seeps out through the material penetration hole 103. It can flow through the trajectory set by the guide strips 3 to make it flow to the area around the anchor rod body 101 more quickly. The guide strips 3 are spaced at regular intervals to make the flow more uniform. At the same time, the guide strips 3 made of silicone rubber increase the friction and fill the anchor rod hole more tightly through their soft and deformable characteristics. The grouting liquid 602 deep in the material penetration hole 103 and the grouting liquid squeezed in by the filling mechanism 5 fill the gaps between the guide strips 3 to avoid the generation of gaps.

[0029] like Figure 5As shown, the push rod 403 has a second threaded groove 406 at its rear end, which is threaded to the threaded rod 405. In this embodiment, the push rod 403 has a second threaded groove 406 (which is an internal thread) near the connecting rod end, which is threaded to the threaded rod 405, making the connecting rod 404 detachable and reusable. This also facilitates the integration of the connecting sleeve 401 and the push rod 403. The connecting rod 404 can be held and force applied to the surface of the sleeve 401. The sleeve 401 can be turned in promptly after the push rod 403 has fully entered the anchor rod body 101, thus optimizing the installation steps.

[0030] like Figure 7 As shown, the grout cylinder 6 includes an outer packaging 601 and grout 602 filled into the inner wall of the outer packaging 601. The outer packaging 601 is a cylindrical polypropylene plastic bag. In this embodiment, the operation of filling the outer packaging 601 with grout 602 and sealing the injection port can be carried out on the ground, reducing the time spent working at heights. This allows most of the grout to be injected into the deep part of the anchor bolt hole at the same time as the anchor bolt rod 1 is installed, making the grouting in the deep part of the anchor bolt hole more thorough.

[0031] like Figure 6 As shown, the cylinder 402 has multiple first feed holes 408, and the sleeve 401 has multiple second feed holes 409. The outlet of the second feed hole 409 protrudes outside the anchor rod body 101. In this embodiment, the filling mechanism 5 fills the cylinder 402 with grout 602. The grout 602 enters the second feed hole 409 through the first feed hole 408 and seeps into the gap between the reinforcing structure 4 and the pit wall, as well as the outward gap between the anchor rod body 101 and the pit wall. Guided by the guide strip 3, it comes into contact with the grout 602 already injected inside, achieving bidirectional filling from the outside to the inside of the anchor hole. This more fully fills the gap between the anchor support and the anchor hole, increases the contact area with the pit wall, and strengthens the support force.

[0032] like Figure 8 and Figure 9As shown, the filling mechanism 5 includes an air pump 501, a connecting pipe 502 fixed to the output end of the air pump 501, a second magnetic ring 510 fixed to the end of the connecting pipe 502 away from the air pump 501, a rubber ring 511 fixed to the front end of the second magnetic ring 510, a transparent hopper 509 fixed to the end of the connecting pipe 502 near the second magnetic ring 510, a PTFE membrane fixed to the end of the transparent hopper 509 near the air pump 501, a second positioning post 512 fixed to the second magnetic ring 510, a positioning hole 412 adapted to the second positioning post 512 provided on the first magnetic ring 413, a through hole for the second positioning post 512 to pass through on the rubber ring 511, and the connecting pipe 502 can be placed on the inner wall of the cylinder 402. In this embodiment, the air pump 501 is existing technology. The air pump 501 and the connecting pipe 502 are fixed in a detachable manner, and the fixing method is also existing technology, which will not be described in detail here. The end of the connecting pipe 502 (soft pipe) away from the air pump 501 is brought into contact with the grouting liquid 602. The air pump 501 is activated to pump the grouting liquid 602 into the transparent hopper 509 through the connecting pipe 502. The PTEE membrane (not shown in the existing technology drawings, it is a breathable but impermeable liquid material) isolates the grouting liquid 602 in the transparent hopper 509. After a suitable amount of grouting liquid 602 is drawn in, the air pump 501 is turned off, and the connecting rod 4 is... 04. Remove the exposed inner wall of the cylinder 402 and align the second positioning pin 512 with the positioning hole 412. At this time, the first magnetic ring 413 and the second magnetic ring 510 are strongly attracted by their strong magnets. The rubber ring 511 improves the sealing after magnetic attraction. The end of the connecting pipe 502 away from the air pump 501 enters the inner wall of the cylinder 402 along with the second magnetic ring 510. Run the air pump to release the air. The gas passes through the PTEE membrane and squeezes the grout 602 into the cylinder 402. The grouting connection method is simple in the above process. The material can be taken according to the grouting volume. The length of the grouting connection pipe is suitable for high-altitude grouting. At the same time, the pipe does not need to be filled with grout to avoid waste.

[0033] The filling mechanism 5 also includes a first fixing plate 506 and a second fixing plate 508. The first fixing plate 506 is fixedly connected to the connecting pipe 502. A slide rod 507 is fixed between the first fixing plate 506 and the second fixing plate 508. A slider 505 is sleeved on the slide rod 507. A long cylinder 504 is integrally formed at the rear end of the slider 505 and sleeved on the connecting pipe 502. A pull plate 503 is integrally formed at the end of the long cylinder 504 away from the slider 505. The pull plate 503 is located at the rear end of the second fixing plate 508. A circular hole is opened in the center of the second fixing plate 508 to slide and connect with the long cylinder 504. In this embodiment, for the anchor rod 1 installed at a high position, the pull plate 503 can be pulled, and the long cylinder 504 and the slider 505 move with the pull plate 503. As the pull plate 503 approaches the air pump 501, the connecting pipe 502, which is supported by the long cylinder 504, the first fixed plate, the second fixed plate 508, and the sliding rod 507, becomes longer. A rubber ring is provided between the slider 505 and the sliding rod 507 to increase friction. The slider 505 has a temporary stopping position on the sliding rod 507. The connecting pipe 502 can be controlled by holding the pull plate 503 or the second fixed plate 508 without climbing, so that the second magnetic ring 510 is attracted to the first magnetic ring 413. Since most of the required grouting liquid 602 has been injected into the grouting cylinder 6, the grouting time of the filling mechanism is shortened. There is no need to work with your head up for a long time and hold the pull plate 503 or the second fixed plate 508. The climbing time caused by grouting can be reduced or avoided, saving time and effort, and improving the safety of the anchor support installation work.

[0034] The slider 505, the long cylinder 504, and the pull plate 503 are all made of resin. In this embodiment, resin is inexpensive, has a smooth surface, and is rigid. It provides support to the connecting pipe 502 and causes minimal wear and damage.

[0035] Example 2 This embodiment provides a working method for the anchor bolt support reinforcement structure described in Embodiment 1, including the following steps: On the ground, the grouting liquid 602 is filled into the outer packaging 601 and the injection port is sealed. First, the piercing part 2 with the tip 205 facing outward is inserted into the anchor bolt hole on the borehole wall. The grout cylinder 6 is placed into the anchor bolt body 101. The threaded rod 405 on the connecting rod 404 contacts the second threaded groove 406 of the push rod 403. The connecting rod 404 and the push rod 403 are installed by rotating them in opposite directions. One end of the third threaded groove 407 on the sleeve 401 faces the push rod 403. The cylinder 402 is then fitted into the connecting rod 404. The anchor bolt body 101 is placed into the anchor bolt hole. Then, the push rod 403 is pushed into the inner wall of the anchor bolt body 101. The grout cylinder 6 contacts the tip 205 with the push rod 403. The grout cylinder 6 is pierced and enters the cavity 202 through the material conveying channel 204 on the cone 201. The grout flows along with the material. The push rod 403 squeezes out of the cavity 202 and the discharge slot 203 to fill the deep part of the anchor bolt hole and the gravel gap. Part of the grout 602 in the grout cylinder 6 seeps out through the material passage hole 103 and can flow more quickly to the area around the anchor bolt body 101 through the trajectory specified by the guide strip 3. After the grout cylinder 6 is squeezed, the sleeve 401 can contact the first threaded groove 104 on the anchor bolt body 101. At the same time, the push rod 403 drives the anchor bolt body 101 to go deeper into the anchor bolt hole (the push rod 403 is wrapped with a silicone rubber layer, and the push rod 403 has a strong friction force in close contact with the inner wall of the anchor bolt body 101 through the silicone rubber layer). The oblique opening 102 contacts the cone 201 and the cone 201 opens the oblique opening, causing the oblique opening position of the anchor bolt body 101 to deform to both sides. The rod body 101 is deformed and locked into the anchor bolt hole. As the anchor bolt body 101 is expanded, part of the grouting liquid 602 in the grout cylinder 6 fills the space between the anchor bolt body 101 and the pit wall through the material passage hole 103. The third thread groove 407 of the sleeve 401 is aligned with the first thread groove 104 on the anchor bolt body 101 and rotated in opposite directions to install the sleeve 401 (at this time, the anchor bolt body 101 does not block the first material inlet hole 408). The sleeve 401 contacts the pit wall. The connecting rod 404 is rotated to unscrew the threaded rod 405, exposing the inner wall of the cylinder 402 and the outward gap between the anchor bolt body 101 and the pit wall. Guided by the guide strip 3, it contacts the grouting liquid 602 that has already been injected inside. The connecting pipe 502 (soft pipe) is moved away from the air pump 501. The end of the pipe 502 contacts the grouting fluid 602. The air pump 501 is activated to draw the grouting fluid 602 into the transparent hopper 509 through the connecting pipe 502. The PTFE membrane isolates the grouting fluid 602 within the transparent hopper 509. After a suitable amount of grouting fluid 602 is drawn in, the air pump 501 is turned off. The connecting rod 404 is removed, exposing it to the inner wall of the cylinder 402. The second positioning post 512 is aligned with the positioning hole 412. At this time, the first magnetic ring 413 and the second magnetic ring 510 are strongly attracted by their powerful magnets. The rubber ring 511 improves the sealing after magnetic attraction. The end of the connecting pipe 502 away from the air pump 501 enters the inner wall of the cylinder 402 along with the second magnetic ring 510. The air pump is activated to release the air, which passes through the PTFE membrane and forces the grouting fluid 602 into the cylinder 402.Grouting fluid 602 enters the gap between the reinforcing structure 4 and the pit wall through the first feed hole 408 of the cylinder 402 and is squeezed into the second feed hole 409 on the sleeve 401. For the anchor rod 1 installed at a high position, the pull plate 503 can be pulled. The long cylinder 504 and the slider 505 move with the pull plate 503. As the pull plate 503 approaches the air pump 501, the connecting pipe 50, which is jointly supported by the long cylinder 504, the first fixed plate 506, the second fixed plate 508 and the slider 507, is connected to the cylinder 50. 2. The length is longer, and a rubber ring is provided between the slider 505 and the slide rod 507 to increase friction. The slider 505 has a temporary stopping position on the slide rod 507, allowing for hand-held control of the connecting pipe 502 via the pull plate 503 or the second fixing plate 508 without climbing, so that the second magnetic ring 510 is attracted to the first magnetic ring 413 for grouting. After grouting is completed, the first positioning post 411 is aligned with the positioning hole 412, and the magnetic cover 410 is attracted to the first magnetic ring 413 to seal the cylinder 402.

[0036] In summary, by setting up the anchor rod part 1, the piercing part 2, the reinforcing structure 4, and the filling mechanism 5, the grouting deep into the anchor bolt hole and the installation of the anchor rod part 1 can be carried out simultaneously. This reduces the time required for grouting, reduces the time required for climbing to install anchor bolt support at heights, achieves bidirectional filling of the deep into the anchor bolt hole from the outside to the inside, more fully fills the gap between the anchor bolt support and the anchor bolt hole, increases the contact area with the pit wall, strengthens the support force, reduces grout waste, and improves the safety of anchor bolt support installation.
