Technical Field

[0001] The present application relates to the technical field of construction site construction, in particular to a sediment cleaning device and method for a supporting rotary drilled cast-in-place pile hole. Background Art

[0002] A supporting rotary drilled cast-in-place pile refers to a deep foundation engineering pile that uses a rotary drilling rig for drill pipe construction, injects cement slurry while forming a hole, and forms a cast-in-place body after excavating the soil. It combines the advantages of rotary drilling and cast-in-place piles, and improves the quality and stability of the pile body by pouring concrete, thereby forming a strong supporting system.

[0003] After construction, there is usually some sediment at the bottom of the pile hole. In order not to affect subsequent construction, manual cleaning is used, but the efficiency of manual cleaning is low, and it is impossible to manually clean deeper piles. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present application is a sediment cleaning device and method for a supporting rotary drilled cast-in-place pile hole to solve the problem of difficult cleaning of sediment in the pile hole.

[0005] The above object of the present application is achieved through the following technical solutions: A sediment cleaning device for a supporting rotary drilled cast-in-place pile hole, including a control board and a cleaning structure at the bottom of the control board for cleaning the sediment at the bottom of the pile hole. An adjusting structure for moving the control board is provided at the upper end of the control board, and the control board is composed of a pair of sector-shaped boards.

[0006] By adopting the above technical solutions, the control board is placed into the pile hole through the adjusting structure. After the control board is placed at the bottom of the pile hole, the sediment at the bottom of the hole is cleaned through the sediment cleaning structure, and mechanical cleaning replaces manual cleaning, thereby solving the technical problem that it is impossible to manually clean deeper pile holes.

[0007] Further, the cleaning structure includes a pair of sector-shaped cleaning boards. One end of the pair of sector-shaped cleaning boards far from their outer arc surfaces is fixedly connected together. An inclined surface is provided at one end of each sector-shaped cleaning board. A rotating shaft is rotatably connected to the middle of the control board. The rotating shaft extends downward between the pair of sector-shaped cleaning boards. The pair of sector-shaped cleaning boards are fixedly connected to the rotating shaft. A butt plate fixedly connected to the control board is provided at the end of the sector-shaped cleaning board far from the inclined surface. A butt inclined surface corresponding to the inclined surface of the sector-shaped cleaning board is provided on the butt plate. An auxiliary cleaning structure is provided at the bottom of the sector-shaped cleaning board, and a driving device for rotating the rotating shaft forward and backward is provided at the upper end of the rotating shaft.

[0008] By adopting the above technical solution, when the control plate falls to the bottom of the pile hole, it is driven by the driving device to drive the rotating shaft to rotate, thereby driving the two fan-shaped cleaning plates to rotate. The inclined surface on the fan-shaped cleaning plate will push the sediment at the bottom of the pile hole onto the fan-shaped cleaning plate. At the same time, when the inclined surface of the fan-shaped cleaning plate reaches the abutting inclined surface on the abutting plate, the fan-shaped cleaning plate will clean up the sediment in the area, and then the control plate will be recovered by adjusting the structure, thereby recovering the cleaning structure.

[0009] Furthermore, the auxiliary cleaning structure includes a second cleaning plate arranged at one end of the bottom of the fan-shaped cleaning plate away from the inclined surface, and a placement groove for placing the second cleaning plate is opened at the bottom of the fan-shaped cleaning plate, and a connecting spring fixedly connected to the fan-shaped cleaning plate is arranged in the placement groove, and the second cleaning plate is fixedly connected to the connecting spring.

[0010] By adopting the above technical solution, the second cleaning plate is first touched to the ground through the adjustment structure before cleaning, and then the fan-shaped cleaning plate is driven to move by the driving device, so that the second cleaning plate pushes the sediment at the bottom of the fan-shaped cleaning plate to one side, and then the control plate is moved under the adjustment structure, and the second control plate is returned to the placement groove as the connecting spring is compressed, and then the fan-shaped cleaning plate is driven to move by the driving device to clean the sediment.

[0011] Furthermore, the driving device includes a forward and reverse motor fixedly connected to the control board, a driving tooth is fixedly connected to the output end of the forward and reverse motor, a driven tooth is fixedly arranged on the rotating shaft, and the driving tooth is meshed with the driven tooth.

[0012] By adopting the above technical solution, the forward and reverse motors are set to drive the rotating shaft to rotate, so that the automatic forward and reverse rotation of the rotating shaft can be achieved.

[0013] Furthermore, the adjustment structure includes a connecting rope fixedly connected to both ends of the control panel, a winding device is provided at the upper end of the connecting rope, and the winding device includes a pair of connecting rods and a connecting frame, the connecting rod is horizontally installed on the connecting frame, two connecting ropes are respectively fixedly connected to the two connecting rods, a pair of connecting rods are rotatably connected to the connecting frame, and a driving gear is fixedly connected to the opposite end of each connecting rod, a driving rod is rotatably provided on the connecting frame, a driving gear is fixedly provided on the driving rod, and the driving gear engages with the driving gear on the two connecting rods, and a power-assisting handle is fixedly provided on the end of the driving rod away from the driving gear, and a placement frame placed outside the pile hole is provided around the connecting frame.

[0014] By adopting the above technical solution, the connecting frame is placed outside the pile hole, and the driving teeth are rotated to drive the driving teeth on both sides to rotate, thereby rotating the connecting rod so that it can lower the two connecting ropes at the same time to achieve simultaneous up and down adjustment. In this application, a motor can also be used to drive the rotating teeth.

[0015] Furthermore, the connecting frame is rotatably connected to the placing frame.

[0016] By adopting the above technical solution, it is convenient to adjust and control the angle of the lower control board.

[0017] Furthermore, extrusion cylinders are arranged on both sides of the control board, and the output ends of the extrusion cylinders face the side wall of the pile hole.

[0018] By adopting the above technical solution, through the arrangement of the extrusion cylinders on both sides, after the control board is lowered, by driving the extrusion cylinders, the output ends of the extrusion cylinders squeeze the side wall of the pile hole, thereby fixing the control board.

[0019] Furthermore, a buffer layer is fixedly connected to the output end of the extrusion cylinder.

[0020] By adopting the above technical solution, the setting of the buffer layer is used to reduce the damage to the output end of the extrusion cylinder.

[0021] Furthermore, the buffer layer is made of a polymer material.

[0022] Furthermore, a method for cleaning sediment in a supporting bored cast-in-place pile hole is applicable to the supporting bored cast-in-place pile hole sediment cleaning device described in any one of the above technical solutions, and includes the following steps:

[0023] S1. Place the placing frame outside the pile hole to ensure that the connecting frame can rotate smoothly;

[0024] S2. Operate the winding device, drive the driven ratchet by rotating the driving ratchet, and then make the connecting rod rotate, and slowly lower the two connecting ropes; as the connecting ropes are lowered, the control board gradually enters the pile hole until its bottom touches the bottom of the pile hole;

[0025] S3. Start the extrusion cylinders on both sides, make their output ends move towards the side wall of the pile hole, and gently squeeze the side wall;

[0026] S4. The buffer layer can reduce the damage to the side wall of the pile hole and ensure that the control board is stably fixed in the pile hole;

[0027] S5. Start the forward and reverse motor, drive the rotating shaft to rotate through the meshing of the driving ratchet and the driven ratchet, the rotating shaft drives the sector-shaped cleaning plate to rotate, and the inclined surface on the sector-shaped cleaning plate pushes the sediment at the bottom of the pile hole to the top of the sector-shaped cleaning plate;

[0028] S6. When the inclined surface of the sector-shaped cleaning plate reaches the abutting inclined surface on the abutting plate, the sector-shaped cleaning plate will clean the sediment in this area;

[0029] S7. While the sector cleaning plate is rotating, if residual sediment is still observed at the bottom of the sector cleaning plate, the auxiliary cleaning structure can be activated;

[0030] S8. The second cleaning plate will move along with the movement of the sector cleaning plate, pushing the sediment at the bottom of the sector cleaning plate to one side;

[0031] S9. When it is necessary to retract the second cleaning plate, the control plate can be slightly lifted through the adjustment structure, so that the second cleaning plate returns to the placement groove along with the compression of the connecting spring;

[0032] S10. After the cleaning is completed, by operating the winding device in the reverse direction, the connecting rope is wound up, thereby slowly lifting the control plate; during the lifting process, ensure that the output end of the extrusion cylinder gradually disengages from the side wall of the pile hole to avoid unnecessary damage to the side wall.

[0033] By adopting the above technical solution, by firmly placing the placement rack outside the pile hole and ensuring that the connecting rack can rotate smoothly, a solid foundation is provided for the entire cleaning operation. With the precise cooperation of the driving ratchet and the driven ratchet, the connecting rod rotates slowly, the two connecting ropes are lowered stably, and the control plate (exquisitely composed of a pair of sector plates) gradually penetrates into the pile hole until its bottom precisely touches the bottom of the pile hole. At this time, the output end of the extrusion cylinder (specially equipped with a buffer layer to reduce damage) gently presses against the side wall of the pile hole, ensuring the stable fixation of the control plate and greatly reducing the potential damage to the pile hole structure.

[0034] The precise start of the forward and reverse motor, through the close meshing of the driving ratchet and the driven ratchet, drives the rotating shaft to rotate efficiently, and then drives the sector cleaning plate to rotate flexibly. The inclined surface on the sector cleaning plate is ingeniously designed, which can effectively push the sediment at the bottom of the pile hole to its top, and when the inclined surface reaches the abutting inclined surface on the abutting plate, the sediment is completely cleaned. At the same time, the addition of the auxiliary cleaning structure (i.e., the second cleaning plate, flexibly connected to the bottom of the sector cleaning plate through a connecting spring) further improves the cleaning efficiency. Especially when dealing with the sediment that may remain at the bottom of the sector cleaning plate, the second cleaning plate can move flexibly along with the movement of the sector cleaning plate, pushing the sediment to one side.

[0035] When it is necessary to retract the second cleaning plate, by slightly lifting the control plate through the adjustment structure, the second cleaning plate easily returns to the placement groove along with the compression of the connecting spring, which is both convenient and efficient. After the cleaning is completed, by operating the winding device in the reverse direction, the connecting rope is slowly wound up, the control plate is stably lifted, and at the same time, ensure that the output end of the extrusion cylinder gradually disengages from the side wall of the pile hole to avoid unnecessary damage.

[0036] In summary, the present application includes the following beneficial technical effects: The sediment cleaning device for the supporting bored cast-in-place pile hole integrates an adjustment structure and a cleaning structure, and adopts a fan-shaped control plate design to achieve efficient mechanized cleaning of the sediment at the bottom of the deep pile hole. This device not only significantly improves the depth and efficiency of the cleaning operation, but also fundamentally solves the problems of difficult, time-consuming and potential safety hazards in manually cleaning the sediment at the bottom of the deep pile hole, ensuring the thoroughness of pile hole cleaning and the safety of construction, and providing a strong guarantee for the construction quality and progress of the bored cast-in-place pile.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following further describes the present application in detail with reference to the accompanying drawings.

[0043] Embodiment, referring to Figure 1 , Figure 2 , a sediment cleaning device for a supporting bored cast-in-place pile hole includes a control plate 1 and a cleaning structure installed at the bottom of the control plate 1. The cleaning structure is used to remove the sediment deposited at the bottom of the pile hole. An adjustment structure is installed at the upper end of the control plate 1, and the adjustment structure can perform up and down movement operations on the control plate 1 to adapt to the cleaning requirements of pile holes at different depths. The control plate 1 adopts a double fan-shaped plate structure, that is, it is composed of a pair of plate bodies shaped like fans spliced together. The cleaning structure includes a pair of fan-shaped cleaning plates 11. These two fan-shaped cleaning plates 11 are fixedly connected together at the end far from their outer arc surfaces to form a complete cleaning surface. An inclined surface is opened at one end of each fan-shaped cleaning plate 11, and these inclined surfaces can effectively push and concentrate the sediment at the bottom of the pile hole during rotation.

[0044] A rotating shaft 12 is rotatably arranged in the middle of the control board 1. The rotating shaft 12 extends downward all the way between a pair of sector-shaped cleaning plates 11. When the rotating shaft 12 rotates, it can drive the sector-shaped cleaning plates 11 to rotate synchronously, thereby generating a cleaning effect and achieving the effect of shoveling up sediment.

[0045] At one end of the sector-shaped cleaning plate 11 away from the inclined surface, there is an abutting plate 13. These abutting plates 13 are fixed on the control board 1. An abutting inclined surface corresponding to the inclined surface of the sector-shaped cleaning plate 11 is provided on the abutting plate 13. When the sector-shaped cleaning plate 11 rotates to a certain angle, its inclined surface will just be embedded in the abutting inclined surface, so as to achieve a more thorough cleaning of sediment.

[0046] In order to further improve the cleaning effect, an auxiliary cleaning structure is also provided at the bottom of the sector-shaped cleaning plate 11. This structure can clean the fine sediment at the bottom of the pile hole more carefully while the sector-shaped cleaning plate 11 rotates.

[0047] In addition, a driving device is installed at the upper end of the rotating shaft 12. This device has a forward and reverse rotation function and can flexibly adjust the rotation direction of the rotating shaft 12 according to needs, so as to achieve precise control of the rotation direction of the sector-shaped cleaning plate 11. Such a design not only improves the cleaning efficiency but also makes the whole cleaning process more flexible and controllable.

[0048] In this embodiment, referring to Figure 4 , the auxiliary cleaning structure includes second cleaning plates 41 provided at one end of the bottom of the sector-shaped cleaning plate 11 away from the inclined surface. A placement groove 42 for placing the second cleaning plates 41 is provided at the bottom of the sector-shaped cleaning plate 11. A connecting spring 43 fixedly connected to the sector-shaped cleaning plate 11 is arranged in the placement groove 42, and the second cleaning plates 41 are fixedly connected to the connecting spring 43. Before cleaning, the second cleaning plates 41 are first made to touch the ground through an adjustment structure, and then the sector-shaped cleaning plate 11 is driven to move by the driving device, so that the second cleaning plates 41 push the sediment at the bottom of the sector-shaped cleaning plate 11 to one side. Then, through the adjustment structure, under the control board 1, the second control board 1 returns to the placement groove 42 as the connecting spring 43 is compressed, and then the sector-shaped cleaning plate 11 is driven to move by the driving device to clean the sediment.

[0049] In this embodiment, the driving device includes a forward and reverse motor 3 fixedly connected to the control board 1. A driving ratchet 31 is fixedly connected to the output end of the forward and reverse motor 3. A driven ratchet 32 is fixedly arranged on the rotating shaft 12. The driving ratchet 31 and the driven ratchet 32 are meshed. By setting the forward and reverse motor 3 to drive the rotating shaft 12 to rotate, the forward and reverse rotation of the rotating shaft 12 can be realized automatically.

[0050] In this embodiment, referring to Figure 3, the adjusting structure includes connecting ropes 22 fixedly connected to both ends of the control board 1. A winding device is provided at the upper end of the connecting rope 22. The winding device includes a pair of connecting rods 21 and a connecting frame 2. The connecting rods 21 are horizontally installed on the connecting frame 2. The two connecting ropes 22 are respectively fixedly connected to the two connecting rods 21. The pair of connecting rods 21 are rotatably connected to the connecting frame 2. A driving ratchet 23 is fixedly connected to each opposite end of each connecting rod 21. A driving rod 24 is rotatably arranged on the connecting frame 2. A driving ratchet 25 is fixedly arranged on the driving rod 24. The driving ratchet 25 meshes with the driving ratchets 23 on the two connecting rods 21. A placing frame 4 placed outside the pile hole is arranged around the connecting frame 2. The placing frame 4 is placed outside the pile hole. By rotating the driving ratchet 25, the driving ratchets 23 on both sides are driven to rotate, so that the connecting rods 21 rotate, and the two connecting ropes 22 are lowered at the same time, realizing simultaneous up and down adjustment. In this application, a motor can also be used to drive the rotating ratchet.

[0051] In this embodiment, the connecting frame 2 is rotatably connected to the placing frame 4, which is convenient for adjusting and controlling the angle of the lower control board 1.

[0052] In this embodiment, extrusion cylinders 33 are arranged on both sides of the control board 1, and the output ends of the extrusion cylinders 33 face the side wall of the pile hole. Through the arrangement of the extrusion cylinders 33 on both sides, after the control board 1 is lowered, by driving the extrusion cylinders 33, the output ends of the extrusion cylinders 33 are made to press against the side wall of the pile hole, thereby fixing the control board 1. A buffer layer 34 is fixedly connected to the output end of the extrusion cylinder 33. The buffer layer 34 is provided to reduce the damage to the output end of the extrusion cylinder 33. The buffer layer 34 is made of a polymer material.

[0053] A method for cleaning sediment in a bored pile hole of a supporting bored cast-in-place pile is applicable to any one of the above technical solutions. A device for cleaning sediment in a bored pile hole of a supporting bored cast-in-place pile includes the following steps:

[0054] S1. Place the placing frame 4 outside the pile hole to ensure that the connecting frame 2 can rotate smoothly;

[0055] S2. Operate the winding device. By rotating the driving ratchet 25 to drive the driving ratchet 23, the connecting rod 21 is further rotated to slowly lower the two connecting ropes 22. As the connecting ropes 22 are lowered, the control board 1 (composed of a pair of sector plates) gradually enters the pile hole until its bottom touches the bottom of the pile hole;

[0056] S3. Start the extrusion cylinders 33 on both sides to make their output ends (with the buffer layer 34) move towards the side wall of the pile hole and gently press the side wall;

[0057] S4. The buffer layer 34 can reduce the damage to the side wall of the pile hole and ensure that the control board 1 is stably fixed in the pile hole;

[0058] S5. Start the forward and reverse motor 3. Through the meshing of the driving ratchet 31 and the driven ratchet 32, drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the fan-shaped cleaning plate 11 to rotate. The inclined plane on the fan-shaped cleaning plate 11 pushes the sediment at the bottom of the pile hole to the top of the fan-shaped cleaning plate 11;

[0059] S6. When the inclined plane of the fan-shaped cleaning plate 11 reaches the abutting inclined plane on the abutting plate 13, the fan-shaped cleaning plate 11 will clean the sediment in this area;

[0060] S7. While the fan-shaped cleaning plate 11 is rotating, if it is observed that there is still residual sediment at the bottom of the fan-shaped cleaning plate 11, the auxiliary cleaning structure can be started;

[0061] S8. The second cleaning plate 41 (connected to the bottom of the fan-shaped cleaning plate 11 through the connecting spring 43) will move with the movement of the fan-shaped cleaning plate 11, pushing the sediment at the bottom of the fan-shaped cleaning plate 11 to one side;

[0062] S9. When the second cleaning plate 41 needs to be retracted, the control plate 1 can be slightly lifted through the adjusting structure, so that the second cleaning plate 41 returns to the placement groove 42 as the connecting spring 43 is compressed;

[0063] S10. After the cleaning is completed, reverse the operation of the winding device to roll up the connecting rope 22, thereby slowly lifting the control plate 1; during the lifting process, ensure that the output end of the extrusion cylinder 33 gradually disengages from the side wall of the pile hole to avoid unnecessary damage to the side wall.

[0064] By firmly placing the placement rack 4 outside the pile hole and ensuring that the connecting rack 2 can rotate smoothly, a solid foundation is provided for the entire cleaning operation. With the precise cooperation of the driving ratchet 25 and the driven ratchet 23, the connecting rod 21 slowly rotates, and the two connecting ropes 22 are steadily lowered. The control plate 1 (composed of a pair of fan-shaped plates) gradually penetrates into the pile hole until its bottom precisely touches the bottom of the pile hole. At this time, the output end of the extrusion cylinder 33 (specially equipped with a buffer layer 34 to reduce damage) gently squeezes the side wall of the pile hole, ensuring the stable fixation of the control plate 1 while greatly reducing the potential damage to the pile hole structure.

[0065] The precise start of the forward and reverse motor 3 drives the rotating shaft 12 to rotate efficiently through the tight meshing of the driving ratchet 31 and the driven ratchet 32, and then drives the sector cleaning plate 11 to rotate flexibly. The inclined plane on the sector cleaning plate 11 is ingeniously designed to effectively push the sediment at the bottom of the pile hole to its top, and when the inclined plane reaches the abutting inclined plane on the abutting plate 13, the sediment is completely cleaned. At the same time, the addition of the auxiliary cleaning structure (i.e., the second cleaning plate 41, which is flexibly connected to the bottom of the sector cleaning plate 11 through the connecting spring 43) further improves the cleaning efficiency. Especially when dealing with the sediment that may remain at the bottom of the sector cleaning plate 11, the second cleaning plate 41 can move flexibly with the movement of the sector cleaning plate 11 and push the sediment to one side.

[0066] When the second cleaning plate 41 needs to be retracted, the control plate 1 is slightly lifted through the adjustment structure, and the second cleaning plate 41 can easily return to the placement groove 42 as the connecting spring 43 is compressed, which is convenient and efficient. After the cleaning is completed, by operating the winding device in reverse, the connecting rope 22 is slowly wound up, and the control plate 1 is steadily lifted. At the same time, it is ensured that the output end of the extrusion cylinder 33 gradually disengages from the side wall of the pile hole, avoiding unnecessary damage.

[0067] Specific implementation process: First, move the entire device near the pile hole to be cleaned and ensure that the placement rack 4 is stably placed outside the pile hole. Then, check all components, including the connecting rope 22, the winding device, the driving device, the cleaning structure, etc., to ensure that they are in good working condition. Next, operate the driving ratchet 25 of the winding device, drive the connecting rod 21 to rotate by driving the ratchet 23, thereby releasing the connecting rope 22, and slowly lower the control board 1 and the cleaning structure at its bottom into the pile hole. During the descent, observe the slack degree of the connecting rope 22 to ensure that the control board 1 descends smoothly and avoid colliding with the pile hole wall. When the control board 1 approaches the bottom of the pile hole, stop releasing the connecting rope 22 and prepare for sediment cleaning. At this time, start the extrusion cylinders 33 on both sides of the control board 1, make the output ends of the cylinders face the side wall of the pile hole and apply a certain pressure, reduce the friction with the pile hole wall through the buffer layer 34, and at the same time provide sufficient fixing force to ensure that the control board 1 remains stable during the cleaning process. Next, first make the second cleaning board 41 touch the ground through the adjusting structure, and use the elasticity of the connecting spring 43 to make the second cleaning board 41 closely adhere to the bottom of the pile hole. Then start the driving device (the forward and reverse motor 3), drive the rotating shaft 12 to rotate, and then make the fan-shaped cleaning board 11 start to rotate. The inclined surface on the fan-shaped cleaning board 11 pushes the sediment at the bottom of the pile hole towards the fan-shaped cleaning board 11. When the inclined surface reaches the abutting inclined surface on the abutting board 13, the fan-shaped cleaning board 11 clears the sediment from the abutting inclined surface. At the same time, the second cleaning board 41, under the push of the rotation of the fan-shaped cleaning board 11, pushes the sediment at the bottom of the fan-shaped cleaning board 11 to one side, further cleaning the bottom of the pile hole. During the cleaning process, observe the cleaning effect and adjust the rotation speed and cleaning time of the driving device as needed. After the cleaning is completed, turn off the driving device and stop the rotation of the fan-shaped cleaning board 11. Then operate the reverse drive of the winding device, make the connecting rod 21 rotate and tighten the connecting rope 22, and slowly lift the control board 1 and the cleaning structure at its bottom back out of the pile hole. During the lifting process, it is also necessary to observe the tension of the connecting rope 22 to ensure that the control board 1 rises smoothly. Finally, after completely removing the control board 1 and its cleaning structure from the pile hole, turn off all power supplies and driving devices, conduct necessary inspections and maintenance on the cleaning device to ensure that it can work properly during the next use, and clean the site, and properly store the device and related tools.

[0068] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.

6. A method for cleaning sediment in a supporting bored cast-in-place pile hole, applicable to the sediment cleaning device for a supporting bored cast-in-place pile hole described in any one of claims 1-5, characterized in that, It includes the following steps: S1. Place the placement frame (4) outside the pile hole to ensure that the connecting frame (2) can rotate smoothly. S2. Operate the winding device to drive the driven ratchet (23) by rotating the driving ratchet (25), thereby rotating the connecting rod (21) and slowly lowering the two connecting ropes (22); as the connecting ropes (22) are lowered, the control board (1) gradually enters the pile hole until its bottom touches the bottom of the pile hole. S3. Start the extrusion cylinders (33) on both sides to make the buffer layers (34) at their output ends move towards the side wall of the pile hole and gently squeeze the side wall. S4. The buffer layer (34) can reduce the damage to the side wall of the pile hole and ensure that the control board (1) is stably fixed in the pile hole. S5. Start the forward and reverse motor (3), drive the rotating shaft (12) to rotate through the meshing of the driving ratchet (31) and the driven ratchet (32), the rotating shaft (12) drives the sector cleaning plate (11) to rotate, and the inclined surface on the sector cleaning plate (11) pushes the sediment at the bottom of the pile hole to the top of the sector cleaning plate (11). S6. When the inclined surface of the sector cleaning plate (11) reaches the abutting inclined surface on the abutting plate (13), the sector cleaning plate (11) will clean the sediment in this area. S7. While the sector cleaning plate (11) is rotating, if it is observed that there is still residual sediment at the bottom of the sector cleaning plate (11), start the auxiliary cleaning structure. S8. The second cleaning plate (41) is connected to the bottom of the sector cleaning plate (11) through a connecting spring (43) and will move with the movement of the sector cleaning plate (11), pushing the sediment at the bottom of the sector cleaning plate (11) to one side. S9. When the second cleaning plate (41) needs to be recycled, slightly lower the control board (1) through the adjustment structure to make the second cleaning plate (41) return to the placement groove (42) as the connecting spring (43) is compressed, and then drive the sector cleaning plate (11) to move through the driving device to clean the sediment. S10. After the cleaning is completed, reverse-operate the winding device to roll up the connecting ropes (22), thereby slowly lifting the control board (1); during the lifting process, ensure that the output end of the extrusion cylinder (33) gradually disengages from the side wall of the pile hole to avoid unnecessary damage to the side wall.
