[0002] A cast-in-place pile is a pile that is made by forming a pile hole in the foundation soil at the construction site through mechanical drilling, steel pipe squeezing or manual excavation, and placing a steel cage inside and pouring concrete. Depending on the hole-forming method, cast-in-place piles can be divided into several categories, such as sunken pipe cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles. Before pouring concrete, the sediment at the bottom of the bored cast-in-place pile needs to be cleaned to improve the strength of the bored cast-in-place pile.

[0034] By adopting the above technical solution, the device can seal the bottom of the slag removal tube 1 through the sealing mechanism after the slag cleaning is completed, wherein when the slag cleaning plate 8 is in the sealing state, it presents a truncated cone structure that is wide at the top and narrow at the bottom, thereby effectively preventing the sediment from falling from the bottom of the slag removal tube 1 during the upward movement, thereby greatly improving the slag cleaning quality and efficiency of the device.

[0035] In the implementation mode of the present application, Figure 2 and Figure 4 As shown, the lifting mechanism includes a second motor 12 installed on the top of the fixed plate 3 and a fixed cylinder 13 installed at the bottom of the fixed plate 3. The output end of the second motor 12 is fixedly connected to an externally threaded rod 14. The bottom of the externally threaded rod 14 extends to the interior of the fixed cylinder 13 and is movably connected to an internally threaded sleeve 15 through a limiting assembly. The bottom of the internally threaded sleeve 15 extends to the bottom of the fixed cylinder 13 and is fixedly connected to the movable plate 4.

[0036] By adopting the above technical solution, the device can quickly adjust the height of the sealing plate 7 through the lifting mechanism, so that the device can quickly clear slag from pile holes of different depths, thereby greatly improving the scope of application and practicality of the device.

[0037] In the implementation mode of the present application, Figure 4 As shown, the limiting assembly includes limiting grooves 16 opened on the inner walls of both sides of the fixing tube 13 , the limiting grooves 16 are internally movably connected with limiting blocks 17 , and the other end of the limiting block 17 is fixedly connected to the internal threaded sleeve 15 .

During adjustment, the operator can start the second motor 12 through the controller 18, so that the second motor 12 can drive the external threaded rod 14 to rotate. When the external threaded rod 14 rotates, it will drive the internal threaded sleeve 15 to move downward under the limiting action of the limiting groove 16 and the limiting block 17, so that the internal threaded sleeve 15 can drive the movable plate 4 to move downward, and then the movable plate 4 can drive the sealing plate 7 to move downward. When the sealing plate 7 moves to the sediment and waste soil at the bottom of the pile hole, the operator uses the rotary drilling rig to drive the sealing plate 7 to rotate, so that the sealing plate 7 can drive the slag guide block 19 to the bottom of the pile hole during the rotation process. The sediment on the top of the slag removal tube 1 is rotated to clean it. When the cleaning is completed, the operator starts the first motor 5 through the controller 18, so that the first motor 5 drives the screw rod 6 to rotate. When the screw rod 6 rotates, it will drive the screw nut 9 to move upward under the limiting action of the connecting rod 10. When the screw nut 9 moves upward, it will drive the slag cleaning plate 8 to flip upward through the connecting rod 10 and the connecting seat 11, so that the sediment on the top of the sealing plate 7 can be blocked. When the angle adjustment of the slag cleaning plate 8 is completed, the operator will lift the sealing plate 7 upward by using the above principle. When the bottom of the slag removal tube 1 contacts the conical inner wall of the slag cleaning plate 8, the slag cleaning plate 8 can be used to block the bottom of the slag removal tube 1, thereby effectively preventing the sediment from falling from the bottom of the slag removal tube 1 during the upward movement, thereby greatly improving the slag cleaning quality and efficiency of the present device.
