A curtain grouting auxiliary device

Abstract

This invention belongs to the field of curtain grouting technology, specifically a curtain grouting auxiliary device. The invention includes a grouting machine, with a fixed ring fixedly connected to the operating platform on one side of the drilling rig. A ratchet is rotatably connected within the fixed ring, and a second grouting pipe is fixed via two conical rollers. The conical rollers allow the first and second grouting pipes to rotate and move simultaneously within the ratchet, enabling the first grouting pipe to be pulled out through the fixed ring while the second grouting pipe remains fixed within it. When the drilling rig is started and reversed, the connector drives the first grouting pipe to reverse as well. At this point, a locking block locks the ratchet, preventing the second grouting pipe from reversing when the first grouting pipe reverses, thus allowing the first grouting pipe to be disassembled from the second grouting pipe. This solves the problem of having to rotate and remove the threaded connector of the grouting pipe first, leading to the inability to disassemble the grouting pipe and requiring secondary disassembly. This reduces the workload of grouting workers and increases the efficiency of grouting pipe disassembly.

Description

Technical Field

[0001] This invention belongs to the field of curtain grouting technology, specifically a curtain grouting auxiliary device. Background Technology

[0002] Curtain grouting is a widely used method to enhance the impermeability of various soil layers and buildings. Curtain grouting involves injecting a special grout into boreholes with a specific spacing. The grout is injected into the cracks and pores of the rock or soil layer, and the grout in each hole is connected to form a curtain-like concrete anti-seepage wall. This cuts off the water flow, reduces the seepage flow and lowers the seepage pressure, thereby achieving the purpose of preventing seepage and plugging leaks.

[0003] During grouting, multiple threaded grouting pipes are inserted into the grouting hole section by section using a threaded connector. After the curtain grouting is completed, the grouting pipes are pulled out section by section using the equipment. When a section of the grouting pipe is completely pulled out, the equipment stops rotating and pulling it out. One end of the grouting pipe is then fixed by manual tools. The equipment is then restarted to rotate the threaded connector in the opposite direction, allowing the grouting pipe to be rotated off and collected.

[0004] The existing equipment described above, when rotating and removing the grouting pipe segment by segment, stops rotating and pulling out a section of the grouting pipe when it is completely pulled out. Then, when workers limit and fix one end of the grouting pipe and reverse it to remove it, the threaded connector of the grouting pipe is rotated off first, leading to the inability to disassemble the grouting pipe and requiring secondary disassembly. Furthermore, disassembling and collecting the grouting pipe is time-consuming and labor-intensive, increasing the workload of workers. The existing method of directly collecting the disassembled grouting pipe after grouting work is completed leaves grout residue inside the pipe and at the grouting port. When the grout solidifies, the effect of the next curtain grouting will be poor, increasing the grouting time required and reducing grouting efficiency.

[0005] Therefore, the present invention provides a curtain grouting auxiliary device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

One end of a transmission rod is fixedly connected to the output end of the motor, and the other end of the transmission rod is rotatably connected to the L-shaped plate. Clamping structures are provided on both sides of the transmission rod. Each clamping structure includes a transmission gear fixedly connected to one side of the transmission rod. Fixed plates are fixedly connected to both sides of the L-shaped plate on the transmission gear. Two intermittent gears are rotatably connected between the two fixed plates on one side of the transmission gear. Both intermittent gears are incomplete gears lacking some teeth. The two intermittent gears mesh with each other. The transmission gear meshes with the intermittent gear near the transmission rod. Clamping rings are fixedly connected to the missing teeth of both intermittent gears. The two clamping rings are opposing semi-circular rings that clamp the first grouting pipe near the clamping ring. The transmission rod is rotatably connected to the fixed plate.

[0011] Preferably, the operating platform is fixedly connected to a support plate on one side of the drilling rig, the operating platform is slidably connected to a moving plate on one side of the support plate, the moving plate is fixedly connected to a fixed cylinder, a fixed frame is fixedly connected to one side of the moving plate, a rotating rod is fixedly connected to the fixed frame, a cleaning block is fixedly connected to one end of the rotating rod, the fixed cylinder is slidably connected to the support plate, and the fixed cylinder is slidably connected to the first grouting pipe.

[0012] Preferably, two positioning blocks are fixedly connected inside the first grouting pipe, and the fixed cylinder has two positioning grooves that match the positioning blocks. The two positioning blocks are slidably connected to the corresponding positioning grooves.

[0013] Preferably, the first grouting pipe has multiple grouting holes, and the fixed cylinder has multiple cleaning structures. Each cleaning structure includes a support cylinder fixedly connected to the fixed cylinder, a limit rod fixedly connected inside the support cylinder, a toothed plate slidably connected between the limit rod and the support cylinder, the limit rod and the toothed plate being slidably connected, a second spring sleeved on the outside of the limit rod, one end of the second spring being fixedly connected to the support cylinder, the other end of the second spring being fixedly connected to the toothed plate, a cleaning column matching the grouting hole being fixedly connected to one end of the toothed plate, multiple racks being fixedly connected to the rotating rod, the multiple racks meshing with the toothed plate, and the fixed cylinder having multiple cleaning holes matching the cleaning column.

[0014] Preferably, limit blocks are fixedly connected to both sides of the toothed plate, and two limit grooves matching the limit blocks are opened in the support cylinder, with the two limit blocks slidably connected to the corresponding limit grooves respectively.

[0015] Preferably, a rotating cylinder is rotatably connected inside the fixed cylinder, the rotating cylinder has multiple movable ports, multiple support cylinders are slidably connected to the movable ports, and the rotating cylinder has multiple cleaning holes that match the cleaning column.

[0016] Preferably, one end of the rotating cylinder is fixedly connected to a ring tooth, one side of the moving plate is rotatably connected to a drive gear, and both the drive gear and one side of the fixed frame are fixedly connected to a rotating handle.

[0017] Preferably, the operating platform is provided with two electric slide rails. The electric slide rail on the side closer to the drilling rig is slidably connected to the drilling rig via a slide table, and the electric slide rail on the side closer to the moving plate is slidably connected to the moving plate via a slide table.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The curtain grouting auxiliary device of the present invention drives the drilling rig to move on the operating table. When the first grouting pipe is fully pulled out, the rotating block is rotated so that one end of the rotating block is locked into the slot. The bolt is screwed into the rotating block and the fixing rod to fix the rotating block. In this way, when the drilling rig reverses and disassembles the first grouting pipe through the connector, the rotating block locks the first grouting pipe, allowing the first grouting pipe to be disassembled from the second grouting pipe. This prevents the first grouting pipe from being rotated off the connector first when disassembling the first grouting pipe. The conical rollers move the first grouting pipe and the second grouting pipe together. The device can rotate and move within the ratchet, allowing the first grouting pipe to be pulled out through the rotating fixed ring. The second grouting pipe is fixed within the fixed ring. When the drilling rig is started and reversed, the connector head drives the first grouting pipe to reverse as well. At this time, the ratchet is locked by the locking block, preventing the second grouting pipe from reversing when the first grouting pipe reverses. This allows the first grouting pipe to be removed from the second grouting pipe, solving the problem of having to rotate and remove the threaded connector of the grouting pipe first, which would prevent the grouting pipe from being removed and require secondary disassembly. This reduces the workload of the grouting workers and increases the efficiency of grouting pipe disassembly.

[0020] 2. The curtain grouting auxiliary device of the present invention, when cleaning residual grout on the grouting hole, fixes the rotating rod to fix the toothed plate through the rack, thereby compressing the second spring through the limiting rod. At this time, the cleaning column is in the fixed cylinder. When the fixing of the rotating rod is removed, the second spring returns to its deformation, causing the toothed plate to move in the support cylinder through the limiting rod. The movement of the toothed plate causes the cleaning column to move, allowing the cleaning column to clean the grouting hole through the cleaning hole. Multiple spirally arranged cleaning structures can clean the spirally arranged grouting holes. After cleaning, rotating the rotating rod causes the toothed plate to move through the rack. The toothed plate moves on the limiting rod to compress the second spring, causing the cleaning column to retract into the fixed cylinder as the toothed plate moves. The fixed cylinder and the cleaning structure can then be removed from the first grouting pipe for the next cleaning. This solves the problem that residual grout in the grouting pipe and grouting port will cause the curtain grouting effect to deteriorate when the grout solidifies, reducing the time required for grouting and accelerating the grouting efficiency.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figures 1 to 11As shown in the embodiment of the present invention, a curtain grouting auxiliary device includes a grouting machine 1, an operating table 2 fixedly connected to the grouting machine 1, a drilling machine 4 slidably connected to the operating table 2, a connector 5 fixedly connected to the output end of the drilling machine 4, a first grouting pipe 6 internally threadedly connected to the connector 5, slots 7 being provided on both sides of the first grouting pipe 6, and a snap-fit ​​structure being provided on both sides of the connector 5. The snap-fit ​​structure includes a fixed rod 8 fixedly connected to one side of the connector 5, a rotating block 9 rotatably connected to the fixed rod 8, and a bolt 11 threadedly connected to the fixed rod 8 and the rotating block 9.

[0037] The operating platform 2 is located on one side of the drilling rig 4 and is fixedly connected to a fixing ring 12. A ratchet 14 is rotatably connected inside the fixing ring 12. A locking block 17 is rotatably connected inside the fixing ring 12 through a connecting column. A connecting rod 18 is fixedly connected to one side of the fixing ring 12 and the locking block 17. A first spring 19 is fixedly connected between the connecting rod 18 and the locking block 17. A placement groove 13 is opened in the ratchet 14. Two fixing blocks 15 are fixedly connected to both sides of the placement groove 13. A conical roller 16 is rotatably connected between the two corresponding fixing blocks 15. The second grouting pipe 37 is fixed by the two conical rollers 16.

[0038] Specifically, after grouting is completed, the drill rig 4 is started to rotate the connector 5, and then the drill rig 4 is driven to move on the operating platform 2. The first grouting pipe 6 can be pulled out segment by segment. When the first grouting pipe 6 is completely pulled out, the rotating block 9 is rotated so that one end of the rotating block 9 is locked into the slot 7. The bolt 11 is screwed into the rotating block 9 and the fixing rod 8 to fix the rotating block 9. In this way, when the drill rig 4 reverses and disassembles the first grouting pipe 6 through the connector 5, the rotating block 9 locks the first grouting pipe 6, allowing the first grouting pipe 6 to be disassembled from the second grouting pipe 37. This prevents the first grouting pipe 6 from being rotated off the connector 5 first when disassembling it. When the drill rig 4 rotates and pulls out the first grouting pipe 6, the conical roller 16 supports and fixes the first grouting pipe 6 and the second grouting pipe 37. The conical roller 16 can make the ratchet 14 fix the first grouting pipe 6 and the second grouting pipe 37 when they rotate. Rotating within ring 12, the first grouting pipe 6 and the second grouting pipe 37 can move simultaneously within ratchet 14 via conical roller 16. This allows the first grouting pipe 6 to be pulled out through the fixed ring 12, while the second grouting pipe 37 remains fixed within the fixed ring 12. When the first grouting pipe 6 is removed from the second grouting pipe 37, the drilling rig 4 reverses, causing the connector 5 to rotate and pull the first grouting pipe 6 in the same direction. At this time, the locking block 17, under the tension of the first spring 19, presses tightly against the ratchet 14, locking the ratchet 14. The conical roller 16 then locks the second grouting pipe 37, preventing it from rotating when the first grouting pipe 6 reverses. This allows the first grouting pipe 6 to be removed from the second grouting pipe 37, solving the problem of having to rotate and remove the threaded connector 5 of the grouting pipe first, which would otherwise prevent the grouting pipe from being removed and necessitate a second disassembly. This reduces the workload of the grouting workers and increases the efficiency of grouting pipe disassembly.

[0039] like Figure 3 As shown, the rotating block 9 is an L-shaped block, and the end of the rotating block 9 is provided with teeth.

[0040] Specifically, when fixing the first grouting pipe 6 by rotating block 9, rotating block 9 is set to L-shape and teeth are set at the end, which can better clamp and fix the first grouting pipe 6 when rotating and disassembling the first grouting pipe 6, so that the first grouting pipe 6 also rotates when the drilling rig 4 drives the connector 5 to rotate.

[0041] like Figure 1 , Figure 4 and Figure 5As shown, a protective plate 3 is fixedly connected to one side of the operating table 2. Two cylinders 20 are fixedly connected to one side of the protective plate 3. An L-shaped plate 21 is fixedly connected to the output ends of the two cylinders 20. A fixed housing 22 is fixedly connected to one side of the L-shaped plate 21. A motor 23 is fixedly connected inside the fixed housing 22. One end of a transmission rod 24 is fixedly connected to the output end of the motor 23. The other end of the transmission rod 24 is rotatably connected to the L-shaped plate 21. Clamping structures are provided on both sides of the transmission rod 24. The clamping structures include transmission gears 25 fixedly connected to one side of the transmission rod 24. The L-shaped plate 21 is located on both sides of the transmission gears 25. A fixed plate 26 is fixedly connected to the transmission gear 25. Two intermittent gears 27 are rotatably connected between the two fixed plates 26 on one side. Both intermittent gears 27 are incomplete gears with missing teeth. The two intermittent gears 27 are meshed together. The transmission gear 25 is meshed with the intermittent gear 27 on the side near the transmission rod 24. Clamping rings 28 are fixedly connected to the missing teeth of the two intermittent gears 27. The two clamping rings 28 are semi-circular rings arranged opposite each other. The first grouting pipe 6 on the side near the clamping rings 28 is clamped by the two clamping rings 28. The transmission rod 24 is rotatably connected to the fixed plate 26.

[0042] Specifically, when the first grouting pipe 6 is removed from the second grouting pipe 37, the cylinder 20 pushes the L-shaped plate 21, which in turn pushes the fixed shell 22 and the fixed plate 26 to move together, causing the motor 23 and the transmission rod 24 to move together with the clamping structure. When the clamping ring 28 is pushed to the first grouting pipe 6, the motor 23 starts and causes the transmission rod 24 to rotate. Through the transmission rod 24, the transmission gear 25 rotates, causing the two intermittent gears 27 to rotate in opposite directions between the fixed plate 26. Through the rotation of the intermittent gears 27, the two clamping rings 28 rotate relative to each other or in opposite directions, so that the clamping rings 28 can rotate and close to clamp the first grouting pipe 6. At this time, the bolt 11 is unscrewed, allowing the rotating block 9 to hang down naturally. The bolt 11 is then screwed in to fix the rotating block 9. At this time, the rotating block 9 leaves the slot 7, releasing the fixation of the first grouting pipe 6. Then, the drilling machine 4 is rotated to make the connector 5 rotate, so that the first grouting pipe 6 can be removed from the connector 5, completing the disassembly of the first grouting pipe 6.

[0043] like Figure 6 As shown, the operating platform 2 is fixedly connected to a support plate 29 on one side of the drilling rig 4. The operating platform 2 is slidably connected to a moving plate 30 on one side of the support plate 29. The moving plate 30 is fixedly connected to a fixed cylinder 31. A fixed frame 34 is fixedly connected to one side of the moving plate 30. A rotating rod 40 is fixedly connected to the fixed frame 34. A cleaning block 41 is fixedly connected to one end of the rotating rod 40. The fixed cylinder 31 is slidably connected to the support plate 29 and to the first grouting pipe 6.

[0044] Specifically, after the first grouting pipe 6 is disassembled, the clamping structure is moved by the cylinder 20 to move the first grouting pipe 6 to one side of the support plate 29. The fixed cylinder 31 is moved into the first grouting pipe 6 by moving the moving plate 30. The movement of the moving plate 30 also moves the fixed frame 34, causing the rotating rod 40 to move. The fixed cylinder 31 drives the rotating cylinder 33 to move together. The movement of the rotating rod 40 causes the cleaning block 41 to move. The grout in the first grouting pipe 6 is cleaned by the movement of the fixed cylinder 31, the rotating cylinder 33 and the cleaning block 41.

[0045] like Figure 7 As shown, two positioning blocks 38 are fixedly connected inside the first grouting pipe 6. The fixed cylinder 31 has two positioning grooves 39 that match the positioning blocks 39. The two positioning blocks 38 are slidably connected to the corresponding positioning grooves 39 respectively.

[0046] Specifically, when the fixed cylinder 31 and the cleaning block 41 are cleaning the grout in the first grouting pipe 6, the fixed cylinder 31 slides on the positioning block 38 through the positioning groove 39, so that the fixed cylinder 31 slides within the first grouting pipe 6 in a limited manner.

[0047] like Figure 8 As shown, the first grouting pipe 6 has multiple grouting holes 46, and the fixed cylinder 31 has multiple cleaning structures. The cleaning structure includes a support cylinder 43 fixedly connected to the fixed cylinder 31. A limit rod 47 is fixedly connected inside the support cylinder 43. A toothed plate 51 is slidably connected between the limit rod 47 and the support cylinder 43. The limit rod 47 and the toothed plate 51 are slidably connected. A second spring 50 is sleeved on the outside of the limit rod 47. One end of the second spring 50 is fixedly connected to the support cylinder 43, and the other end of the second spring 50 is fixedly connected to the toothed plate 51. A cleaning column 52 matching the grouting hole 46 is fixedly connected to one end of the toothed plate 51. A rotating rod 40 is fixedly connected to multiple racks 42. The multiple racks 42 are meshed with the toothed plate 51. The fixed cylinder 31 has multiple cleaning holes 45 matching the cleaning column 52.

[0048] Specifically, when cleaning the residual grout on the grouting hole 46, the fixed rotating rod 40 fixes the toothed plate 51 through the rack 42, thereby compressing the second spring 50 through the limiting rod 47. At this time, the cleaning column 52 is inside the fixed cylinder 31. When the fixing of the rotating rod 40 is released, the second spring 50 returns to its deformation, causing the toothed plate 51 to move within the support cylinder 43 through the limiting rod 47. The movement of the toothed plate 51 causes the cleaning column 52 to move, allowing the cleaning column 52 to clean the grouting hole 46 through the cleaning hole 45. The multiple spiral cleaning structures can clean the spirally arranged grouting hole 46. After cleaning the grouting hole 46, the rotating rod 40 is rotated to move the toothed plate 51 via the rack 42. The toothed plate 51 moves on the limiting rod 47 to compress the second spring 50, causing the cleaning column 52 to retract into the fixed cylinder 31 as the toothed plate 51 moves. This allows the fixed cylinder 31 and the cleaning structure to be removed from the first grouting pipe 6 for the next cleaning. This solves the problem of residual grout in the grouting pipe and grouting port, which would cause the grouting effect of the next curtain grouting to deteriorate when the grout solidifies. It also reduces the time required for grouting and speeds up the grouting efficiency.

[0049] like Figure 9 As shown, limit blocks 48 are fixedly connected to both sides of the toothed plate 51, and two limit grooves 49 matching the limit blocks 48 are opened in the support cylinder 43. The two limit blocks 48 are slidably connected to the corresponding limit grooves 49 respectively.

[0050] Specifically, when the toothed plate 51 moves within the support cylinder 43, the movement of the toothed plate 51 within the support cylinder 43 is limited by the sliding of the limiting block 48 within the limiting groove 49, so that the toothed plate 51 can move better within the support cylinder 43.

[0051] like Figure 1 As shown, the operating table 2 is equipped with two electric slide rails 53. The electric slide rail 53 on the side closer to the drilling rig 4 is slidably connected to the drilling rig 4 through the slide table, and the electric slide rail 53 on the side closer to the moving plate 30 is slidably connected to the moving plate 30 through the slide table.

[0052] Specifically, when moving the drilling rig 4 and the moving plate 30, the drilling rig 4 and the moving plate 30 are moved by two electric slide rails 53 respectively.

[0053] Example 2

[0054] like Figure 11 As shown in Example 1, another embodiment of the present invention is as follows:

[0055] A rotating cylinder 33 is rotatably connected inside the fixed cylinder 31. The rotating cylinder 33 has multiple moving ports 44. Multiple support cylinders 43 are slidably connected to the moving ports 44. The rotating cylinder 33 has multiple cleaning holes 45 that match the cleaning column 52.

[0056] Specifically, when the cleaning of the grouting hole 46 is completed and the cleaning column 52 is retracted into the fixed cylinder 31, the rotating cylinder 33 is rotated to block the cleaning hole 45 on the fixed cylinder 31, so that the cleaning column 52 is inside the rotating cylinder 33. This prevents the cleaning column 52 from popping out when the rotating rod 40 is not fixed. When the cleaning column 52 needs to pop out for cleaning, the rotating cylinder 33 is rotated to remove the obstruction of the cleaning hole 45 on the fixed cylinder 31, allowing the cleaning column 52 to clean the grouting hole 46 through the rotating cylinder 33 and the cleaning hole 45 on the fixed cylinder 31.

[0057] like Figure 4 As shown, a ring tooth 32 is fixedly connected to one end of the rotating cylinder 33, and a drive gear 35 is rotatably connected to one side of the moving plate 30. A rotating handle 36 is fixedly connected to one side of both the drive gear 35 and the fixed frame 34.

[0058] Specifically, when the rotating cylinder 33 or the rotating rod 40 needs to rotate, the drive gear 35 and the rotating rod 40 are rotated by rotating the handle 36. The rotation of the drive gear 35 causes the rotating cylinder 33 to rotate through the ring gear 32, thus providing driving force for the rotation of the rotating rod 40 and the rotating cylinder 33.

[0059] Working principle: After grouting is completed, the drill rig 4 is started to rotate the connector 5, and then the drill rig 4 is driven to move on the operating platform 2. The first grouting pipe 6 can be pulled out segment by segment. When the first grouting pipe 6 is completely pulled out, the rotating block 9 is rotated so that one end of the rotating block 9 is locked into the slot 7. The bolt 11 is screwed into the rotating block 9 and the fixing rod 8 to fix the rotating block 9. In this way, when the drill rig 4 reverses and disassembles the first grouting pipe 6 through the connector 5, the rotating block 9 locks the first grouting pipe 6, allowing the first grouting pipe 6 to be disassembled from the second grouting pipe 37. This prevents the first grouting pipe 6 from being rotated off the connector 5 first when disassembling it. When the drill rig 4 rotates and pulls the first grouting pipe 6 out, The first grouting pipe 6 and the second grouting pipe 37 are supported and fixed by the conical roller 16. The conical roller 16 allows the ratchet 14 to rotate within the fixing ring 12 as the first grouting pipe 6 and the second grouting pipe 37 rotate. The conical roller 16 allows the first grouting pipe 6 and the second grouting pipe 37 to move simultaneously within the ratchet 14, enabling the first grouting pipe 6 to be pulled out through the fixing ring 12 while the second grouting pipe 37 remains fixed within the fixing ring 12. When the first grouting pipe 6 is removed from the second grouting pipe 37, the drilling rig 4 reverses, causing the connector 5 to rotate the first grouting pipe 6 in the same direction. At this time, the locking block 17, under the tension of the first spring 19, presses tightly against the ratchet 14, locking the ratchet 14. The second grouting pipe 37 is then locked by the conical roller 16, preventing it from reversing when the first grouting pipe 6 reverses. This allows the first grouting pipe 6 to be removed from the second grouting pipe 37. When the first grouting pipe 6 is fixed by the rotating block 9, the rotating block 9 is L-shaped with teeth at the end, which better clamps and fixes the first grouting pipe 6 during rotational disassembly, so that the first grouting pipe 6 rotates together with the connecting head 5 when the drilling rig 4 rotates. When the first grouting pipe 6 is removed from the second grouting pipe 37, the cylinder 20 pushes the L-shaped plate 21, which in turn pushes the fixing shell 22 and the fixing plate 26 to move together, causing the motor 23 and the transmission rod 24 to move along with the clamping structure. When the clamping ring 28 is pushed to the first grouting pipe 6, the transmission rod 24 rotates when the motor 23 starts. The transmission rod 24 causes the transmission gear 25 to rotate, which in turn causes the two intermittent gears 27 to rotate in opposite directions between the fixed plate 26. The rotation of the intermittent gears 27 causes the two clamping rings 28 to rotate relative to each other or in opposite directions, so that the clamping rings 28 can rotate and close to clamp the first grouting pipe 6. At this time, the bolt 11 is unscrewed so that the rotating block 9 hangs down naturally. The bolt 11 is then screwed in to fix the rotating block 9. At this time, the rotating block 9 leaves the slot 7 and the fixation of the first grouting pipe 6 is released. Then the drilling machine 4 is rotated to make the connector 5 rotate, so that the first grouting pipe 6 can be removed from the connector 5, and the disassembly of the first grouting pipe 6 is completed.

[0060] After the first grouting pipe 6 is disassembled, the clamping structure is moved by the cylinder 20 to move the first grouting pipe 6 to one side of the support plate 29. The moving plate 30 is moved to move the fixed cylinder 31 into the first grouting pipe 6. The movement of the moving plate 30 also moves the fixed frame 34, causing the rotating rod 40 to move. The fixed cylinder 31 drives the rotating cylinder 33 to move together. The movement of the rotating rod 40 causes the cleaning block 41 to move. Through the movement of the fixed cylinder 31, the rotating cylinder 33, and the cleaning block 41, the contents of the first grouting pipe 6 are cleaned. The grout is cleaned; when the fixed cylinder 31 and the cleaning block 41 clean the grout in the first grouting pipe 6, the fixed cylinder 31 slides on the positioning block 38 through the positioning groove 39, so that the fixed cylinder 31 slides within the first grouting pipe 6 within a limited range; when cleaning the residual grout on the grouting hole 46, the fixed rotating rod 40 fixes the toothed plate 51 through the rack 42, so that the second spring 50 is compressed through the limiting rod 47. At this time, the cleaning column 52 is inside the fixed cylinder 31. When the fixing of the rotating rod 40 is released, The second spring 50 recovers its deformation, causing the toothed plate 51 to move within the support cylinder 43 via the limiting rod 47. This movement of the toothed plate 51 moves the cleaning column 52, allowing it to clean the grouting hole 46 through the cleaning hole 45. The multiple spirally arranged cleaning structures can clean the spirally arranged grouting hole 46. After cleaning, rotating the rotating rod 40 moves the toothed plate 51 via the rack 42. The movement of the toothed plate 51 on the limiting rod 47 compresses the second spring 50, causing the cleaning column 52 to move along with the toothed plate 51. The fixed cylinder 31 and the cleaning structure can be moved out of the first grouting pipe 6 to allow for the next cleaning cycle. When the toothed plate 51 moves within the support cylinder 43, the movement of the toothed plate 51 within the support cylinder 43 is limited by the sliding of the limiting block 48 within the limiting groove 49, allowing the toothed plate 51 to move more effectively within the support cylinder 43. When moving the drilling rig 4 and the moving plate 30, the drilling rig 4 and the moving plate 30 are moved separately by two electric slide rails 53.

[0061] When the cleaning of the grouting hole 46 is completed and the cleaning column 52 is retracted into the fixed cylinder 31, the rotating cylinder 33 is rotated to block the cleaning hole 45 on the fixed cylinder 31, keeping the cleaning column 52 inside the rotating cylinder 33. This prevents the cleaning column 52 from popping out when the rotating rod 40 is not fixed. When the cleaning column 52 needs to pop out for cleaning, the rotating cylinder 33 is rotated to remove the obstruction of the cleaning hole 45 on the fixed cylinder 31, allowing the cleaning column 52 to clean the grouting hole 46 through the rotating cylinder 33 and the cleaning hole 45 on the fixed cylinder 31. When the rotating cylinder 33 or the rotating rod 40 needs to be rotated, the drive gear 35 and the rotating rod 40 are rotated by rotating the handle 36. The rotation of the drive gear 35 causes the rotating cylinder 33 to rotate through the ring gear 32, thus providing driving force for the rotation of the rotating rod 40 and the rotating cylinder 33.
