[0002] Prestressed piles are hollow cylindrical slender concrete precast components made by prestressing technology and centrifugal forming. They are mainly composed of a square pile body, end plates and steel hoops.
[0003] After the construction process of prestressed square piles using the pre-tensioning method, the pressed piles are mostly left independently under the surface. After the piles are delivered and pulled out, the soil layer will be squeezed toward the pile hole under the action of pressure and gravity, causing the soil to squeeze into the hollow tube of the pressed pile. When the earthwork is excavated to the pile head, the pile core will be in a filled state, which will not only affect the subsequent construction, but the long-term retention will gradually increase the hardness of the soil inside the hollow tube, making the subsequent core pouring process more difficult.
[0004] The current treatment method is to fill the pile with water and use a long-handled scoop to repeatedly dig and clean. Not only is the construction method primitive and costly, but the hollow tube of the pile needs to be further pumped out after filling to avoid a reduction in concrete strength during core pouring.

[0016] Furthermore, the moving mechanism includes a rack 21 longitudinally arranged on the positioning column 2, a sleeve 22 is mounted on the positioning column 2, a rotating tube is rotatably connected inside the sleeve 22, a gear meshing with the rack 21 is mounted on the rotating tube, and the sleeve 22 extends from one end of the rotating tube and is connected to a hand crank 23. The hand crank 23 drives the rotating tube and the rack 21 to rotate, thereby driving the sleeve 22 to move up and down along the rack 21 on the positioning column 2.
[0017] Furthermore, a foot platform 6 is connected to the side of the fixed frame 1 away from the pile hole, an inclined support 62 is arranged between the positioning column 2 and the middle of the foot platform 6, and a height-adjustable support leg 61 is arranged at the bottom of the foot platform 6. The position around the pile is often lower than the pile top. After the fixed frame 1 is placed on the pile top, workers often have nowhere to stand stably when operating the hand crank 23. The workers can stand stably through the foot platform 6, and the support leg 61 is suitable for bottom surfaces of different heights.
[0018] Furthermore, the rotating rod 4 includes a connecting rod connected to the output end of the rotating motor 3, an extension rod is connected to the bottom of the connecting rod, a cleaning rod is arranged at the bottom of the extension rod, the spiral blade 5 is arranged on the cleaning rod, the cleaning rod cleans the soil, and the extension rod is used to adapt to piles of different depths.
