Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering disaster prevention and control, and more specifically, to an integrated device for filling and reinforcing fissures in unstable rock masses. The invention also relates to a method of using this integrated device for filling and reinforcing fissures in unstable rock masses. Background Technology

[0002] In the field of geotechnical engineering, the stability of unstable rock masses has always been a key factor concerning engineering safety and environmental safety. Unstable rock masses typically refer to geological bodies that are cut and separated by multiple structural planes, have poor stability, and may collapse in the form of toppling, falling, or sliding. Their existence seriously threatens the safety of surrounding buildings, transportation facilities, and the lives and property of people. The reinforcement of unstable rock masses usually involves drilling anchor bolts into both the unstable rock mass and the parent rock mass simultaneously, and then binding the two anchor bolts together with steel strands to fix the relative position of the unstable rock mass and the parent rock mass through the prestress formed by the two anchor bolts.

[0003] The existing integrated device for filling and reinforcing fissures in unstable rock masses has a relatively simple connection structure between anchor bolts during use, resulting in poor fixing effect. Furthermore, the anchor bolts, which are vertically inserted into the parent rock mass, are prone to swaying within the receiving groove, affecting the reinforcement effect.

[0004] Therefore, in view of the above situation, there is an urgent need to provide an integrated device for filling and reinforcing fissures in dangerous rock masses and its application method, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0007] To achieve the aforementioned first objective, the technical solution of the present invention is as follows: an integrated device for filling and reinforcing fissures in unstable rock masses, characterized in that: it includes a first anchor rod, a second anchor rod detachably connected to the side of the first anchor rod, a connecting mechanism, and a locking mechanism; the first anchor rod is a hollow structure, a first limiting block is provided at the top of the first anchor rod, a plurality of first filling holes are spaced apart on the side of the first anchor rod, and a first feeding pipe communicating with the first anchor rod is provided on the first limiting block;

Multiple second filling holes are spaced apart on the side of the second anchor rod. A second feed pipe communicating with the second anchor rod is provided on the second limiting block.

[0009] The connecting mechanism includes a rotating rod disposed inside the second anchor rod. One end of the rotating rod passes through the second limiting block and is fixedly connected to the driving block, and the other end passes through the second anchor rod and is provided with a first external thread.

[0010] The locking mechanism is located inside the first anchor rod; the first external thread is detachably connected to the locking mechanism via a thread.

[0011] In the above technical solution, the connecting mechanism further includes a support base and a threaded rod; the support base is fixedly installed on the second limiting block; one end of the threaded rod is provided with a knob, and the other end passes through the support base and is connected to the locking block. The threaded rod is threadedly connected to the knob, and the locking block is used to lock the rotating rod.

[0012] In the above technical solution, the locking mechanism includes a locking tube, a guide assembly, and a locking assembly; the locking tube is located inside the first anchor rod, and both ends of the locking tube penetrate the side wall of the first anchor rod and are flush with the outer wall of the first anchor rod;

[0013] The guide assembly includes a guide rod fixed inside the locking tube, a first spring fitted on the guide rod, and a support frame slidably connected to the guide rod;

[0014] The locking assembly includes a clamping block and a pressing rod; a support rod is provided in the middle of the clamping block, and the support rod is slidably connected to the pressing rod; the second external thread on the outer wall of the pressing rod is connected to the internal thread on the inner wall of the locking tube; the first external thread matches the internal thread; the support frame is fitted onto the pressing rod.

[0015] In the above technical solution, a linkage block is provided on the rotating rod, and a hexagonal hole matching the linkage block is provided on the pressing rod; a second spring is provided between the pressing block and the pressing rod; the second spring is fitted on the support rod.

[0016] The above technical solution also includes a first blocking component, which includes a first blocking cover located inside the first anchor bolt, a first connecting hole opened on the first blocking cover and matching the first filling hole, and a rotating shaft rotatably installed inside the first anchor bolt; a first gear and a second gear are fixedly installed on the rotating shaft;

[0017] The outer wall of the support frame is provided with a rack that meshes with the first gear; the inner wall of the first blocking cover is provided with an inner toothed ring that meshes with the second gear.

[0018] In the above technical solution, the first blocking cover has an opening at the locking mechanism.

[0019] The above technical solution also includes a second blocking component, which includes a second blocking cover located inside the second anchor rod and fitting against the second anchor rod, a second connecting hole on the second blocking cover that matches the second filling hole, and a spring with one end fixedly connected to the rotating rod and the other end fixedly connected to the second blocking cover; when the spring is in its natural state, the second filling hole and the second connecting hole are offset from each other.

[0020] In the above technical solution, a limiting block is provided at one end of the second anchor rod near the first anchor rod, and a groove is opened on the second blocking cover to slide with the limiting block.

[0021] In the above technical solution, both the first limiting block and the second limiting block are provided with fixing rings; the end of the second anchor rod near the first anchor rod is an arc-shaped concave surface that fits against the side of the first anchor rod.

[0022] To achieve the second objective mentioned above, the technical solution of the present invention is: a method for using an integrated device for filling and reinforcing fissures in unstable rock masses, characterized by comprising the following steps:

[0023] Step 1: Open a receiving groove in the parent rock for placing the first anchor rod, and open a receiving groove in the secondary dangerous rock for placing the second anchor rod. The shape of the top of the receiving groove corresponds to the first limiting block and the second limiting block.

[0024] Step 2: After the first and second anchor rods are placed into their corresponding receiving slots, continue pushing the second limiting block, causing it to press the end of the second anchor rod towards the first anchor rod. Simultaneously, the driving block drives the rotating rod to rotate. When the linkage block is engaged in the hexagonal hole, the rotation of the rotating rod drives the pressing rod to rotate. Utilizing the meshing of the second external thread and the internal thread, the pressing rod moves towards the abutment block during rotation. At the same time, after the rotating rod extends into the locking tube, the first external thread meshes with the internal thread, achieving a stable connection between the rotating rod and the locking tube. The continuous rotation of the rotating rod causes the pressing rod to move continuously, thereby using the second spring to push the abutment block against the side wall of the second anchor rod, achieving a stable connection between the first and second anchor rods.

[0025] Step 3: In step 2, when the rotating rod rotates, the spring pulls the second blocking cover to rotate. Due to the limiting effect of the limiting block, the second blocking cover stops after rotating with the rotating rod at a certain angle. At this time, the second filling hole coincides with the second connecting hole, and the filling operation can be performed.

[0026] During the movement of the support frame, the rack will move synchronously. The meshing of the rack with the first gear will drive the rotating shaft to rotate. The meshing of the rotating shaft with the second gear will drive the inner gear ring to rotate. The inner gear ring will drive the first blocking cover to rotate. Since the movement displacement of the support frame is restricted by the opening, the first blocking cover will stop after rotating a certain angle. At this time, the first filling hole and the first connecting hole coincide, and the filling operation can be performed.

[0027] Step 4: After reinforcement is completed, rotate the knob to drive the threaded rod to rotate, causing the threaded rod to move to one side of the rotating rod. Use the locking block to press the rotating rod to fix it and prevent the rotating rod from rotating.

[0028] Compared with the prior art, the present invention has the following advantages.

[0029] 1) By combining the connecting mechanism and the locking mechanism, this invention avoids the problems of existing integrated devices for filling and reinforcing cracks in dangerous rock masses, where the connection structure between anchor rods is relatively simple, the fixing effect is poor, and the anchor rods inserted vertically into the parent rock mass are prone to swaying in the receiving groove, affecting the reinforcement effect.

[0030] 2) The first and second blocking components of the present invention effectively prevent impurities such as sand and gravel from entering the first and second anchor rods during installation, thereby improving the reinforcement effect. Attached Figure Description

[0050] The connecting mechanism 300 includes a rotating rod 310 disposed in the second anchor rod 200. One end of the rotating rod 310 passes through the second limiting block 210 and is fixedly connected to the driving block 320, and the other end passes through the second anchor rod 200 and is provided with a first external thread 330. A polygonal hole is provided in the driving block 320, preferably a triangular hole, to facilitate the use of a triangular wrench.

[0051] The locking mechanism 400 is disposed inside the first anchor rod 100; the first external thread 330 is detachably connected to the locking mechanism 400 via a thread.

[0052] The connecting mechanism 300 also includes a support base 340 and a threaded rod 350; the support base 340 is fixedly installed on the second limiting block 210; one end of the threaded rod 350 is provided with a knob 351, and the other end passes through the support base 340 and is connected to the locking block 352. The threaded rod 350 is threadedly connected to the knob 351, and the locking block 352 is used to lock the rotating rod 310.

[0053] The locking mechanism 400 includes a locking tube 410, a guide assembly 420, and a locking assembly 430; the locking tube 410 is located inside the first anchor rod 100, and both ends of the locking tube 410 penetrate the side wall of the first anchor rod 100 and are flush with the outer wall of the first anchor rod 100.

[0054] The guide assembly 420 includes a guide rod 421 fixed inside the locking tube 410, a first spring 422 fitted on the guide rod 421, and a support frame 423 slidably connected to the guide rod 421; the locking tube 410 has strip grooves on both sides, and the guide rod 421 is fixedly installed in the strip grooves; the first spring 422 provides elastic support to the support frame 423;

[0055] The locking assembly 430 includes a clamping block 431 and a pressing rod 432; a support rod 433 is provided in the middle of the clamping block 431, and the support rod 433 is slidably connected to the pressing rod 432; the second external thread 4321 on the outer wall of the pressing rod 432 is connected to the internal thread 411 on the inner wall of the locking tube 410; the first external thread 330 matches the internal thread 411; the support frame 423 is rotatably fitted onto the pressing rod 432 to achieve stable sliding and rotational guidance of the pressing rod 432 within the locking tube 410.

[0056] A linkage block 311 is provided on the rotating rod 310, and a hexagonal hole 4322 matching the linkage block 311 is provided on the pressing rod 432; a second spring 434 is provided between the pressing block 431 and the pressing rod 432; the second spring 434 is fitted on the support rod 433.

[0057] The invention can provide multiple sets of first anchor rods 100, and each set of first anchor rods 100 can be equipped with multiple sets of second anchor rods 200. The invention utilizes the locking mechanism 400 and the connecting mechanism 300 to achieve a precise connection between the first anchor rods 100 and the second anchor rods 200, thereby achieving a reinforcement function. The invention uses a first feed pipe 111 to introduce filling material into the first anchor rod 100, which then flows out through the first filling hole 120, facilitating the fixing of the first anchor rod 100 into the receiving groove. The invention also utilizes a second feed pipe 211 and a guide channel 230. The combined design allows the filling material to be introduced into the second anchor rod 200 and flow out through the second filling hole 220. This achieves fixation between the second anchor rod 200 and the receiving groove, while some of the filling material can enter the crack to fill it and further improve the reinforcement effect. The filling material is preferably an acrylate, which has excellent fluidity and can penetrate into ultra-fine cracks below 0.01mm. After curing, it becomes an elastomer with good impermeability and is suitable for filling fine cracks in humid environments. It is especially suitable for scenarios with complex crack networks that require comprehensive penetration reinforcement.

[0058] It also includes a first blocking assembly 500, which includes a first blocking cover 510 located inside the first anchor bolt 100, a first communicating hole 520 opened on the first blocking cover 510 and matching the first filling hole 120, and a rotating shaft 530 rotatably installed inside the first anchor bolt 100; a first gear 531 and a second gear 532 are fixedly installed on the rotating shaft 530.

[0059] The outer wall of the support frame 423 is provided with a rack 4231 that meshes with the first gear 531; the inner wall of the first blocking cover 510 is provided with an inner toothed ring 511 that meshes with the second gear 532.

[0060] The first blocking cover 510 is provided with an opening 512 at the corresponding locking mechanism 400; the opening 512 ensures that the first blocking cover 510 will not interfere with the locking tube 410 during rotation.

[0061] It also includes a second blocking assembly 600, which includes a second blocking cover 610 located inside the second anchor rod 200 and in contact with the second anchor rod 200, a second connecting hole 620 opened on the second blocking cover 610 that matches the second filling hole 220, and a spring 630 whose one end is fixedly connected to the rotating rod 310 and whose other end is fixedly connected to the second blocking cover 610; when the spring 630 is in its natural state, the second filling hole 220 and the second connecting hole 620 are offset from each other.

[0062] A limiting block 640 is provided at one end of the second anchor rod 200 near the first anchor rod 100, and a groove is provided on the second blocking cover 610 to slide with the limiting block 640.

[0063] Both the first limiting block 110 and the second limiting block 210 are provided with fixing rings 700. The fixing rings 700 facilitate the connection and fixation of multiple sets of second limiting blocks 210 and first limiting blocks 110 using steel strands, thereby further reinforcing the first anchor rod 100 and the second anchor rod 200 and improving the reinforcement effect on the parent rock and the sub-rock. The end of the second anchor rod 200 near the first anchor rod 100 has an arc-shaped concave surface that fits against the side of the first anchor rod 100, which facilitates a tight fit between the second anchor rod 200 and the first anchor rod 100, thereby improving the reinforcement effect.

[0064] A method for using an integrated device for filling and reinforcing fissures in unstable rock masses, characterized by comprising the following steps:

[0065] Step 1: A receiving groove for placing the first anchor rod 100 is opened on the parent rock, and a receiving groove for placing the second anchor rod 200 is opened on the secondary dangerous rock. The shape of the top of the receiving groove corresponds to the first limiting block 110 and the second limiting block 210.

[0066] Step 2: After the first anchor rod 100 and the second anchor rod 200 are placed into their corresponding receiving slots, continue pushing the second limiting block 210, causing the second limiting block 210 to press the end of the second anchor rod 200 towards the first anchor rod 100, and simultaneously using the driving block 320 to drive the rotating rod 310 to rotate; when the linkage block 311 is engaged in the hexagonal hole 4322, the rotation of the rotating rod 310 can drive the pressing rod 432 to rotate, utilizing the meshing action of the second external thread 4321 and the internal thread 411 This causes the pressing rod 432 to move toward the abutment block 431 when it rotates. At the same time, after the rotating rod 310 extends into the locking tube 410, the first external thread 330 will engage with the internal thread 411, realizing a stable connection between the rotating rod 310 and the locking tube 410. The continuous rotation of the rotating rod 310 causes the pressing rod 432 to move continuously, thereby using the second spring 434 to push the abutment block 431 to press against the side wall of the second anchor rod 200, effectively preventing the first anchor rod 100 from shaking in the receiving groove and improving the reinforcement effect.

[0067] Step 3: In step 2, when the rotating rod 310 rotates, the spring 630 pulls the second blocking cover 610 to rotate. Due to the limiting effect of the limiting block 640, the second blocking cover 610 stops after rotating with the rotating rod 310 at a certain angle. At this time, the second filling hole 220 coincides with the second connecting hole 620, and the filling operation can be performed.

[0068] During the movement of the support frame 423, the rack 4231 will move synchronously. The meshing of the rack 4231 with the first gear 531 will drive the rotating shaft 530 to rotate. The meshing of the rotating shaft 530 with the second gear 532 will drive the inner gear ring 511 to rotate. The inner gear ring 511 will drive the first blocking cover 510 to rotate. Since the movement displacement of the support frame 423 is limited by the opening 512, the first blocking cover 510 will stop after rotating a certain angle. At this time, the first filling hole 120 coincides with the first connecting hole 520, and the filling operation can be performed.

[0069] Step 4: After reinforcement is completed, rotate the knob 351 to drive the threaded rod 350 to rotate, so that the threaded rod 350 moves to the side of the rotating rod 310. Use the locking block 352 to press the rotating rod 310 to fix the rotating rod 310 and prevent the rotating rod 310 from rotating.

[0070] In practical use, the present invention utilizes the supporting effect of the second spring 434 to change the distance between the pressing block 431 and the pressing rod 432, which facilitates meeting the feeding requirements of the rotating rod 310 and achieving a stable connection between the first anchor rod 100 and the second anchor rod 200. The guiding effect of the guide rod 421 and the elastic supporting effect of the first spring 422 further improve the stability of the first gear 531 during movement. The outer walls of both the first anchor rod 100 and the second anchor rod 200 are provided with crisscrossing grooves to increase the friction between them and the inner wall of the receiving groove, while allowing the filling material to penetrate between the first anchor rod 100, the second anchor rod 200, and the inner wall of the receiving groove, thereby improving the reinforcement effect. The end of the pressing block 431 has a crisscrossing toothed groove structure 4311 to increase friction.

[0071] The width of the first connecting hole 520 is greater than the diameter of the first filling hole 120. Therefore, the first blocking cover 510 can make the first connecting hole 520 coincide with the first filling hole 120 within a certain angle range.

[0072] Multiple sets of second filling holes 220 are arranged in an array along the length of the second anchor rod 200, and multiple sets of first filling holes 120 are arranged in an array along the length of the first anchor rod 100. This facilitates improved filling effect. When the second anchor rod 200 passes through the crack, the filling material can be injected into the crack using the second filling holes 220. By setting multiple sets of second anchor rods 200, injection can be performed at different locations, thereby improving the filling effect. At the same time, the arrangement of multiple sets of first filling holes 120 and second filling holes 220 can also evenly inject the filling material into the receiving groove, achieving a stable connection between the first anchor rod 100, the second anchor rod 200, and the receiving groove, further preventing loosening and thus improving the reinforcement effect.

[0073] All other unspecified parts belong to the prior art.

6. The integrated device for filling and reinforcing fissures in unstable rock masses according to claim 5, characterized in that: The first blocking cover (510) has an opening (512) at the locking mechanism (400).

7. The integrated device for filling and reinforcing fissures in unstable rock masses according to claim 5, characterized in that: It also includes a second blocking assembly (600), which includes a second blocking cover (610) located inside the second anchor rod (200) and fitting against the second anchor rod (200), a second connecting hole (620) opened on the second blocking cover (610) that matches the second filling hole (220), and a spring spring (630) with one end fixedly connected to the rotating rod (310) and the other end fixedly connected to the second blocking cover (610); when the spring spring (630) is in its natural state, the second filling hole (220) and the second connecting hole (620) are offset from each other.

8. The integrated device for filling and reinforcing fissures in unstable rock masses according to claim 7, characterized in that: A limiting block (640) is provided at one end of the second anchor rod (200) near the first anchor rod (100), and a groove is provided on the second blocking cover (610) to slide with the limiting block (640).

9. The integrated device for filling and reinforcing fissures in unstable rock masses according to claim 1, characterized in that: Both the first limiting block (110) and the second limiting block (210) are provided with fixing rings (700); the second anchor rod (200) has an arc-shaped concave surface that fits against the side of the first anchor rod (100) at the end near the first anchor rod (100).

10. A method for using an integrated device for filling and reinforcing fissures in unstable rock masses, characterized in that, Includes the following steps: Step 1: A receiving groove for placing the first anchor rod (100) is opened on the parent rock, and a receiving groove for placing the second anchor rod (200) is opened on the secondary dangerous rock. The shape of the top of the receiving groove corresponds to the first limiting block (110) and the second limiting block (210). Step 2: After the first anchor rod (100) and the second anchor rod (200) are placed into their respective receiving slots, continue to push the second limiting block (210), so that the second limiting block (210) drives the end of the second anchor rod (200) to press towards the first anchor rod (100), and at the same time, the driving block (320) drives the rotating rod (310) to rotate; when the linkage block (311) is inserted into the hexagonal hole (4322), the rotation of the rotating rod (310) can drive the pressing rod (432) to rotate, and the meshing action of the second external thread (4321) and the internal thread (411) is utilized. This causes the pressing rod (432) to move toward the abutment block (431) when it rotates. At the same time, after the rotating rod (310) extends into the locking tube (410), the first external thread (330) will engage with the internal thread (411), realizing a stable connection between the rotating rod (310) and the locking tube (410). The continuous rotation of the rotating rod (310) causes the pressing rod (432) to move continuously, thereby using the second spring (434) to push the abutment block (431) to press against the side wall of the second anchor rod (200), realizing a stable connection between the first anchor rod (100) and the second anchor rod (200). Step 3: In step 2, when the rotating rod (310) rotates, the spring (630) pulls the second blocking cover (610) to rotate. Due to the limiting effect of the limiting block (640), the second blocking cover (610) stops after rotating a certain angle with the rotating rod (310). At this time, the second filling hole (220) coincides with the second connecting hole (620), and the filling operation can be performed. During the movement of the support frame (423), the rack (4231) will move synchronously. The meshing of the rack (4231) with the first gear (531) will drive the rotating shaft (530) to rotate. The meshing of the rotating shaft (530) with the second gear (532) will drive the inner gear ring (511) to rotate. The inner gear ring (511) will drive the first blocking cover (510) to rotate. Since the movement displacement of the support frame (423) is limited by the opening (512), the first blocking cover (510) will stop after rotating a certain angle. At this time, the first filling hole (120) and the first connecting hole (520) coincide, and the filling operation can be performed. Step 4: After reinforcement is completed, rotate the knob (351) to drive the threaded rod (350) to rotate, so that the threaded rod (350) moves to the side of the rotating rod (310). Use the locking block (352) to press the rotating rod (310) to fix the rotating rod (310) and prevent the rotating rod (310) from rotating.
