Description

Technical Field

[0001] This application relates to the field of anchor bolt implantation technology, specifically a post-pressure grouting anchor bolt implantation reinforcement system. Background Technology

[0002] Anchor bolt support is a widely used support method in slope reinforcement projects. Its basic principle is to drill holes at predetermined locations on the slope, insert anchor bolts into the holes, and grout them to form a unified structure with the surrounding soil and rock. Combined with subsequent slope construction, this effectively improves the stability of the slope. In existing slope anchor bolt reinforcement construction, multiple sets of anchor bolts are typically first stacked at a designated storage point on the construction site. During construction, the anchor bolts are spliced ​​on-site according to the design depth requirements of each borehole. The spliced ​​anchor bolts are then transported to the respective borehole locations for insertion. After the anchor bolts are in place, pressure grouting is performed into the holes using grouting equipment, filling the gaps between the anchor bolts and the borehole walls with grout, ultimately forming a stable anchoring system.

[0003] However, in actual operation, the existing construction method described above requires the anchor bolt installation equipment to sequentially complete the installation of each group of boreholes on the slope. During equipment movement, operators or transport equipment need to repeatedly travel between the stacking point and each construction borehole to move the anchor bolts. As the number of boreholes increases and the construction area expands, the frequency and distance of anchor bolt transportation increase significantly, consuming a large amount of manpower and resources, and affecting the overall anchor bolt installation efficiency.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figures 1-5 As shown, this embodiment of the invention discloses a post-pressure grouting anchor bolt implantation reinforcement system, which is installed on the surface of a slope 1. A support frame 101 is installed on the surface of the slope 1, and a load plate 102 is installed on the support frame 101. The system includes an operating platform 2, a guide frame 3, an anchor bolt seat 4, and a limiting mechanism. A storage box 201 is installed on the top of the operating platform 2. A partition 202 is provided inside the storage box 201, which divides the storage box 201 into a grouting groove 203 and a bolt groove 204. The operating platform 2 is also equipped with... A grouting mechanism is provided to inject cement grout into the borehole. A guide frame 3 is inclinedly set at the bottom of the operating table 2. The upper end of the guide frame 3 is provided with a through hole for connecting rod groove 204. An anchoring seat 4 is set on the operating table 2. The anchoring seat 4 is provided with a V-shaped groove 401, which is aligned with the bottom of the guide frame 3. A push rod mechanism is provided on the anchoring seat 4 to insert the anchor rod into the borehole. A limiting mechanism is set on the anchoring seat 4 to adjust the movement of the anchor rod on the guide frame 3.

[0021] In at least one embodiment, the limiting mechanism includes a motor, a turntable 5, a protrusion 501, a crossbar 502, and a stop bar 504. The planting base 4 has an installation cavity 405. The turntable 5 is rotatably disposed in the installation cavity 405. The protrusion 501 is fixedly disposed on the turntable 5. The crossbar 502 is slidably disposed in the installation cavity 405. The crossbar 502 has a groove 503 in the middle. The protrusion 501 is slidably disposed in the groove 503. The two ends of the top of the crossbar 502 are fixedly disposed with stop bars 504. The top of the installation cavity 405 has a through hole aligned with the stop bar 504. The guide frame 3 has a groove aligned with the stop bar 504. The motor is fixedly disposed on the outer wall of the planting base 4. The output shaft of the motor is fixedly connected to one end of the turntable 5.

[0022] When the operating platform 2 moves to the drilling position, the anchor bolt unit section in the rod groove 204 moves to the inclined section of the guide frame 3 through the through hole on the guide frame 3, and the stop bar 504 in the limiting mechanism abuts and blocks the lowest anchor bolt unit section. When it is necessary to move the anchor bolt into the V-groove 401, the operator starts the motor 1 on the outer wall of the rod planting seat 4. The output shaft of the motor 1 drives the turntable 5 to rotate. The protrusion 501 on the turntable 5 pushes the crossbar 502 in the mounting cavity 405 by abutting against the inner wall of the sliding groove 503 on the crossbar 502. The horizontal bar 502 moves up and down, which in turn causes the top of the stop bar 504 at the top of the horizontal bar 502 to extend and retract. When the stop bar 504 retracts into the perforation, a set of anchor bolt unit sections on the guide frame 3 rolls down along the inclined guide frame 3, thereby moving into the V-shaped groove 401 of the anchor bolt seat 4. After a set of anchor bolt unit sections fall, the horizontal bar 502 causes the top of the stop bar 504 to extend above the guide frame 3, thereby blocking the next set of anchor bolt unit sections, realizing the control of the falling of the anchor bolt unit sections, and ensuring the effective advancement of the anchor bolt in the V-shaped groove 401.

[0023] In at least one embodiment, the push rod mechanism includes a hydraulic rod 402, a mounting base 403, and a push plate. The mounting base 403 is fixedly disposed at one end of the rod holder 4, and the hydraulic rod 402 is fixedly disposed on the mounting base 403. The output shaft of the hydraulic rod 402 is aligned with the V-groove 401 and is provided with a push plate.

[0024] After the anchor bolt unit section falls into the V-groove 401, the operator splices the anchor bolt unit section in the borehole with the anchor bolt unit section in the V-groove 401. Then, the hydraulic rod 402 is activated, and the output shaft of the hydraulic rod 402 drives the push plate to extend, thereby abutting against the anchor bolt unit section in the V-groove 401 and pushing it into the borehole, thus completing the implantation of the anchor bolt.

[0025] In at least one embodiment, the grouting mechanism includes a grouting pump 6 and a grouting pipe 601. The bottom of the grouting tank 203 is provided with a discharge port, which is connected to the inlet of the grouting pump 6. The discharge port of the grouting pump 6 is connected to one end of the grouting pipe 601.

[0026] After the anchor bolts are fully implanted in a set of boreholes, the operator starts the grouting pump 6 and performs grouting operations in the boreholes through the grouting pipe 601. During grouting, the grout is injected from the bottom of the borehole to the outside of the borehole to ensure effective penetration of the grout into the borehole sidewall.

[0027] In at least one embodiment, a connecting rod 301 is provided on the guide frame 3, a pressure plate 302 is fixedly provided at the bottom of the connecting rod 301, and screws 303 are rotatably provided on both sides of the guide frame 3, with each end of the connecting rod 301 being fitted with a set of screws 303.

[0028] The operator rotates the screws 303 on both sides of the guide frame 3 according to the size of the anchor bolt unit section. The screws 303 and the connecting rod 301 are threaded together to drive the connecting rod 301 and the pressure plate 302 to rise and fall. The distance between the pressure plate 302 and the top surface of the guide frame 3 is adjusted to control the arrangement of the anchor bolt unit sections falling from the through hole to the inclined section of the guide frame 3, so as to ensure that the anchor bolt unit sections are arranged as a whole on the guide frame 3 and to ensure the smooth falling of the anchor bolt unit sections.

[0029] In at least one embodiment, a fixed rod 205 is fixedly installed on the top of the operating platform 2, and the storage box 201 is fixedly connected to the fixed rod 205. The bottom of the fixed rod 205 is provided with a countersunk hole penetrating the operating platform 2. A frame 7 and a hydraulic rod 701 are provided at the bottom of the operating platform 2. The top of the frame 7 is inserted into the countersunk hole, and a crossbeam is fixedly installed at the bottom of the frame 7. The two ends of the hydraulic rod 701 are respectively connected to the operating platform 2 and the crossbeam. When the operating platform 2 moves along the loading plate 102 to the drilling position, the operator activates the hydraulic rod 701 according to the drilling position, so that the output shaft of the hydraulic rod 701 pushes and moves the frame 7, thereby adjusting the height of the anchor rod seat 4 to ensure that the anchor rod unit section in the V-groove 401 is aligned with the drilling hole.

[0030] In at least one embodiment, a track 103 is provided on the loading plate 102, and a slot aligned with the track 103 is provided at the bottom of the frame 7. A roller is rotatably provided in the slot, and the operating table 2 moves along the track 103 via the roller, thereby improving the ease of movement of the operating table 2.

[0031] In at least one embodiment, the end of the anchoring base 4 away from the hydraulic rod 402 is rotatably connected to the operating table 2. The end of the anchoring base 4 near the hydraulic rod 402 is provided with a hydraulic rod 404. The bottom of the hydraulic rod 404 is hinged to the operating table 2, and the top of the hydraulic rod 404 is hinged to the top of the anchoring base 4. The operator starts the hydraulic rod 404 according to the inclination angle of the borehole. The output shaft of the hydraulic rod 404 drives the end of the anchoring base 4 near the hydraulic rod 402 to be lifted, thereby changing the angle between the anchoring base 4 and the hydraulic rod 402, ensuring that the anchor rod in the V-groove 401 is accurately implanted into the borehole.

[0032] In at least one embodiment, a motor 8 is fixedly installed on the outer wall of the storage tank 201, and a rotating shaft is rotatably installed inside the grouting tank 203. An agitator 801 is fixedly installed on the rotating shaft. The output shaft of the motor 8 is connected to one end of the rotating shaft. During the grouting operation, the operator starts the motor 8, and the output shaft of the motor 8 drives the rotating shaft and the agitator 801 to rotate, thereby agitating the cement slurry in the grouting tank 203 and ensuring the fluidity of the cement slurry.

[0033] In at least one embodiment, the bottom of both the grouting groove 203 and the rod groove 204 is provided with an inclined surface, and the cement grout and anchor rod unit sections in the grouting groove 203 and the rod groove 204 can fall along the inclined surface at the bottom to ensure the smoothness of the material falling.

[0034] In at least one embodiment, a control terminal is provided on the operating table 2, and a limit switch 304 is provided at one end of the guide frame 3 near the anchor rod seat 4. The limit switch 304, hydraulic rod one 402, hydraulic rod two 701, hydraulic rod three 404, motor one, and motor two 8 are all electrically connected to the control terminal. The operator can conveniently control each part through the control terminal. The operation is convenient. After the stop bar 504 is retracted into the hole, the anchor rod unit section on the guide frame 3 falls along the inclined section. When the anchor rod unit section moves to the lowest end of the guide frame 3 and falls, it presses the limit switch 304 on the guide frame 3. At this time, the control terminal starts motor one again through the transmission signal of the limit switch 304, so that motor one drives the stop bar 504 to extend to the top surface of the guide frame 3, thereby blocking the subsequent anchor rod unit section.

[0035] When performing anchor bolt installation and reinforcement work on a slope, operators erect steel pipe support frames 101 step by step from bottom to top along the slope, and lay load plates 102 on the support frames 101. The support frames 101 and load plates 102 are fixed with bolts. Then, drilling equipment drills holes on the load plates 102 according to the set arrangement. After drilling, the drilling equipment uses a high-pressure air blowing device to clean the holes of sediment. Afterwards, the operator moves the operating platform 2 to the load plate 102 and moves it horizontally along the drilling direction. At this time, the storage box 20 on the top of the operating platform 2... The grouting tank 203 inside the 1 contains cement grout, and the anchor bolt unit sections are arranged in the rod groove 204. Each anchor bolt unit section has an internal threaded hole and an external threaded section at both ends. When the operating platform 2 moves to the drilling position, the operator uses the limiting mechanism on the rod base 4 to move the anchor bolt unit sections in the rod groove 204 one by one into the V-shaped groove 401 on the rod base 4 via the inclined guide frame 3. Then, the push rod mechanism on one side of the rod base 4 pushes the anchor bolt unit sections in the V-shaped groove 401 towards the drilling hole, causing the anchor bolt unit sections to partially insert into the drilling hole. The push rod mechanism completes the pushing of the anchor bolt unit sections and then... After repositioning, the limiting mechanism controls another set of anchor bolt unit sections to move into the V-groove 401. At this time, the operator splices the anchor bolt unit sections in the borehole with those in the V-groove 401 using threaded connections. After splicing, the push rod mechanism pushes and inserts the spliced ​​anchor bolt. The operator's on-site splicing of the anchor bolt unit sections ensures the stability of the spliced ​​sections. Compared to transporting the spliced ​​anchor bolts from the stacking point to each set of boreholes, this avoids accidental loosening during the movement of the spliced ​​anchor bolts. Through the reciprocating operation of the limiting mechanism and the push rod mechanism, multiple anchor bolt units are... The anchor bolt unit sections are moved and spliced ​​one by one and then inserted into the borehole to complete the anchor bolt implantation. Afterwards, the cement grout in the grouting groove 203 is injected into the borehole through the grouting mechanism on the operating platform 2 to complete the grouting operation. After the anchor bolt implantation and grouting operation are completed for a set of boreholes, the operating platform 2 moves along the carrying plate 102 to the next set of boreholes. In the overall reinforcement operation, by placing the anchor bolt unit sections and cement grout in the rod groove 204 and grouting groove 203 in the storage box 201 respectively, the operator avoids having to repeatedly travel back and forth to move the anchor bolts from the anchor bolt stacking point, thus improving the anchor bolt implantation efficiency.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
