Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to a reinforcement anchor bolt based on tunnel construction. Background Art

[0002] Tunnel construction is the abbreviation of the New Austrian Tunnel Construction Method. It is a reasonable construction method proposed by Austrian scholars from the perspective of rock mechanics during their long-term tunnel construction practice. It is a new engineering construction method formed by adopting shotcrete technology, monitoring and measurement, and a system composed of rock mechanics theory. During tunnel construction, it is generally necessary to use anchor bolts to reinforce various components inside the tunnel so that the components inside the tunnel fit tightly with the rock wall. However, when using anchor bolts, chemical anchor bolts are generally used to achieve reinforcement work. Chemical anchor bolts generally place chemicals into the inside of the hole first, and then insert the anchor bolt into the hole, puncture the chemicals, so that the chemicals stick to the anchor bolt and the inside of the hole, and then perform other operations to complete the installation of the anchor bolt. However, the above operations make the installation steps of the anchor bolt cumbersome and the installation efficiency low. At the same time, because the protective layer on the surface of the chemical agent is very thin, the user needs to be very careful when taking the chemical agent, which is very easy to cause safety accidents. Therefore, we propose a reinforced anchor bolt that can integrate the chemical agent and the anchor bolt, which is convenient for users to take and store it, and omits the step of placing the chemical agent, thereby improving its installation efficiency. Summary of the Invention

[0003] In response to the deficiencies in the prior art, the present invention provides a reinforced anchor bolt based on tunnel construction, which solves the problem of placing chemicals into the interior of the hole, then inserting the anchor bolt into the hole, puncturing the chemical agent, allowing the chemical effect to stick to the anchor bolt and the inside of the hole, and then performing other operations to complete the installation of the anchor bolt. However, the above operations make the installation steps of the anchor bolt cumbersome and the installation efficiency low. At the same time, since the protective layer on the surface of the chemical agent is very thin, the user needs to be very careful when taking the chemical agent, which is very prone to safety accidents.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A reinforcement anchor bolt for tunnel construction includes an anchor rod, a positioning plate fixedly mounted on one side of the anchor rod, a reinforcement mechanism provided inside the anchor rod, the reinforcement mechanism including a threaded hole extending through the interior of the anchor rod, and a threaded rod threadedly mounted inside the threaded hole.

[0006] A plurality of guide grooves and connecting grooves are provided inside the threaded hole, and a storage bag is provided inside each of the guide grooves;

[0007] A push plate is movably installed inside each of the connecting grooves, and the ends of the push plates close to each other are respectively fitted with the threaded rods;

[0008] A plurality of guide grooves are provided on one side of the anchor rod away from the positioning plate, and the guide grooves are respectively connected to the guide grooves.

[0009] Preferably, temporary storage grooves are provided inside the guide grooves, and the storage bags are placed inside the temporary storage grooves respectively;

[0010] The storage bag is used for storing chemicals.

[0011] Preferably, a placement groove is provided inside the threaded hole and on the side away from the positioning plate, and the placement grooves are respectively connected to the guide grooves. A connecting block is movably installed in the middle of the placement groove, and the connecting block is also movably installed inside the threaded hole, and the connecting block and the push plate fit together.

[0012] Preferably, a plurality of blades are installed on the outer sides of the connecting blocks, and the blades are movably installed inside the guide grooves, and the blades are used to cut the storage bags;

[0013] The connecting block and the threaded rod are fitted with each other.

[0014] Preferably, the push plate has a rounded corner at one end close to the positioning plate;

[0015] A plurality of positioning rods are fixedly mounted on one end of the push plate away from the threaded rod. One end of the positioning rods is set to be conical, and the positioning rods are used to be inserted into the hole to assist in positioning the anchor rod.

[0016] Preferably, both ends of the connecting groove, which are inside the connecting groove and away from the threaded rod, are provided with stoppers, and the stoppers are used to limit the push plate.

[0017] Preferably, a sealing groove is provided on the side of the positioning plate away from the anchor rod, and the sealing groove and the threaded hole are connected to each other. A nut is installed on one end of the threaded rod located on the outside of the positioning plate through a thread, and a sealing plate is installed on one side of the nut, and the sealing plate and the threaded rod are movably connected, and the sealing plate is snap-fitted and installed inside the sealing groove.

[0018] 1. In the present invention, the storage bag is placed inside the temporary storage tank, so that the chemical agent and the anchor rod form a whole, which is convenient for users to carry the whole, and at the same time will not damage the chemical agent to cause safety accidents, and better protect it. When installing the anchor bolt, it is only necessary to insert the anchor rod into the drilled hole, and then rotate the threaded rod so that the threaded rod drives the blade to cut the storage bag, causing the chemical agent to leak, allowing the chemical agent to enter the hole and the threaded hole along the guide groove, so that the hole, anchor rod and threaded rod are adhered by the chemical agent, which greatly improves the stability of the anchor bolt after installation, and also improves the overall installation efficiency, which is more convenient.

[0019] 2. In the present invention, after the threaded rod enters the threaded hole through the thread, the threaded rod will squeeze the push plate through the rounded corners, so that the push plate drives the positioning rod to insert into the hole, which can not only position the anchor rod so that the anchor rod is located in the middle of the hole, but also facilitate the flow of chemicals, allowing the chemicals to fill the space between the anchor rod and the hole more evenly, and also increase the contact area between the anchor rod and the hole, thereby maximizing the stability of the anchor rod after installation.

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, a reinforcement anchor bolt based on tunnel construction includes an anchor rod 1, a positioning plate 2 is fixedly installed on one side of the anchor rod 1, a reinforcement mechanism 4 is provided inside the anchor rod 1, and the reinforcement mechanism 4 includes a threaded hole 401, which is provided through the interior of the anchor rod 1, and a threaded rod 3 is installed inside the threaded hole 401 through a thread;

[0031] The threaded hole 401 is provided with a plurality of guide grooves 402 and connecting grooves 408 , and each guide groove 402 is provided with a storage bag 404 ;

[0032] A push plate 409 is movably installed inside each connecting groove 408, and the ends of the push plates 409 close to each other are respectively fitted with the threaded rod 3;

[0033] A plurality of guide grooves 8 are provided on a side of the anchor rod 1 away from the positioning plate 2 , and the guide grooves 8 are respectively connected to the guide grooves 402 .

[0034] like Figure 4 and Figure 6 As shown, temporary storage grooves 403 are respectively provided inside the guide grooves 402, and storage bags 404 are respectively placed inside the temporary storage grooves 403; the storage bags 404 are used to store chemical agents.

[0035] By placing the chemical agent inside the storage bag 404 and then placing the storage bag 404 inside the temporary storage tank 403, the chemical agent and the anchor rod 1 can be integrated. This makes it convenient for the user to install the anchor bolt by simply placing the anchor rod 1 inside the drilled hole and then rotating the threaded rod 3 to complete the installation of the anchor rod 1. This eliminates the need for the user to place the chemical agent inside the hole, thereby improving the installation efficiency of the anchor bolt.

[0036] Furthermore, by placing the chemical agent inside the anchor rod 1, the chemical agent can be better protected, and it is also convenient to store the chemical agent when the anchor bolt is not needed, thereby better protecting the chemical agent.

[0037] like Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a placement groove 405 is provided inside the threaded hole 401 and on a side away from the positioning plate 2, and the placement grooves 405 are respectively connected to the guide grooves 402, and a connecting block 406 is movably installed in the middle of the placement groove 405, and the connecting block 406 is also movably installed inside the threaded hole 401, and the connecting block 406 and the push plate 409 fit together, and a plurality of blades 407 are respectively installed on the outside of the connecting block 406, and the blades 407 are movably installed inside the guide groove 402, and the blades 407 are used to cut the storage bag 404; the connecting block 406 and the threaded rod 3 fit together, and the push plate 409 is provided with a rounded corner at one end close to the positioning plate 2; Several positioning rods 410 are fixedly installed on the end of the push plate 409 away from the threaded rod 3. One end of the positioning rod 410 is set to be conical, and the positioning rod 410 is used to insert into the hole to assist in positioning the anchor rod 1. The inside of the connecting groove 408 and both ends away from the threaded rod 3 are provided with blocks, and the blocks are used to limit the push plate 409. The side of the positioning plate 2 away from the anchor rod 1 is provided with a sealing groove 7, and the sealing groove 7 and the threaded hole 401 are connected to each other. The end of the threaded rod 3 located on the outside of the positioning plate 2 is threadedly installed with a nut 5, and a sealing plate 6 is installed on one side of the nut 5, and the sealing plate 6 and the threaded rod 3 are movably connected, and the sealing plate 6 is snap-fitted and installed inside the sealing groove 7.

[0038] After the user has completed drilling the hole, the anchor rod 1 can be inserted into the hole. After the anchor rod 1 is inserted, the positioning plate 2 will fit with the inner wall of the tunnel or the component box, so that the positioning plate 2 can seal the hole to avoid leakage when the chemical is filled.

[0039] Then, after the anchor rod 1 is inserted, the user can install the threaded rod 3 through the thread, allowing the threaded rod 3 to enter the threaded hole 401 through the thread, and then as the threaded rod 3 continues to move, the threaded rod 3 will connect with the connecting block 406, and then as the threaded rod 3 continues to move, the connecting block 406 will push the push plate 409 through the rounded corner of the push plate 409, allowing the push plate 409 to drive the positioning rod 410 to extend outward, and finally allowing the push plate 409 to fit with the stop block, completing the pushing work of the push plate 409;

[0040] After the push plate 409 has moved, the positioning rod 410 is inserted into the hole through the conical top, thereby limiting the position of the anchor rod 1 and increasing the contact area between the anchor rod 1 and the hole, thereby improving the tightness between the anchor rod 1 and the hole when the chemical is filled, making the anchor rod 1 more stable;

[0041] After the push plate 409 is moved, as the threaded rod 3 continues to enter the threaded hole 401, the connecting block 406 drives the blade 407 to cut the storage bag 404, allowing the chemical inside the storage bag 404 to initially flow out, and the chemical enters the hole and the threaded hole 401 along the guide groove 402 to fill and adhere, completing the installation of the anchor rod 1;

[0042] When the anchor rod 1 is not in use, the connecting block 406 drives the blade 407 to be located inside the guide groove 402 and close to one end of the positioning plate 2, so that after the threaded rod 3 enters the threaded hole 401, the connecting block 406 is pushed, so that the connecting block 406 drives the blade 407 to cut the storage bag 404;

[0043] In order to ensure that the blade 407 does not damage the storage bag 404 when not in use, a silicone pad can be placed between the blade 407 and the storage bag 404 to separate the blade 407 and the storage bag 404. When needed, the silicone pad can be pulled out and used normally. The silicone pad can be reused, thereby reducing the production cost of the anchor bolt.

[0044] Then, after the threaded rod 3 is installed, the user drives the sealing plate 6 to be installed on the outside of the threaded rod 3 through the nut 5, and fits the sealing plate 6 with the sealing groove 7, which can not only assist in sealing between the threaded rod 3 and the threaded hole 401, but also help improve the stable connection of the threaded rod 3.

[0045] The working principle of this reinforcement anchor bolt based on tunnel construction:

[0046] When in use, first, after the hole is drilled, the user can insert the anchor rod 1 into the inside of the hole. Then, after the anchor rod 1 is inserted, the positioning plate 2 will fit with the inner wall of the tunnel or the component box. Then, after the anchor rod 1 is inserted, the user can install the threaded rod 3 through the thread, allowing the threaded rod 3 to enter the threaded hole 401 through the thread. Then, as the threaded rod 3 continues to move, the threaded rod 3 will connect with the connecting block 406. Then, as the threaded rod 3 continues to move, the connecting block 406 will push the push plate 409 through the rounded corner of the push plate 409, allowing the push plate 409 to drive the positioning rod 410 to extend outward, and finally allowing the push plate 409 to fit with the stop block, completing the pushing work of the push plate 409.

[0047] After the push plate 409 is moved, as the threaded rod 3 continues to enter the threaded hole 401, the connecting block 406 drives the blade 407 to cut the storage bag 404, allowing the chemical inside the storage bag 404 to initially flow out, and the chemical enters the hole and the threaded hole 401 along the guide groove 402 to fill and adhere, completing the installation of the anchor rod 1;

[0048] When the chemical agent is filled, the guide groove 8 guides the chemical agent to flow, thereby maximizing the filling degree of the chemical agent and allowing the chemical agent to adhere more tightly to the hole and the anchor rod 1;

[0049] Then, after the threaded rod 3 is installed, the user drives the sealing plate 6 to be installed on the outside of the threaded rod 3 through the nut 5, and fits the sealing plate 6 with the sealing groove 7, which can not only assist in sealing between the threaded rod 3 and the threaded hole 401, but also help improve the stable connection of the threaded rod 3.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
