mounting the fixed seat on the end part of the tubular pile and enabling the first through hole to correspond to the pile core; providing a sleeve cap, wherein the sleeve cap is columnar and hollow, the bottom end of the sleeve cap is open, the top end of the sleeve cap is provided with a top plate, the top plate corresponds to the pile core and is provided with a second through hole matched with the pile core, the sleeve cap is sleeved on the end part of the pile, the fixed seat is installed on the sleeve cap, the first through hole, the second through hole and the pile core are aligned, the side wall of the sleeve cap is provided with a plurality of through holes, the through holes are fixedly provided with nuts, the threaded holes of the nuts are aligned with the through holes, a first fastener is provided, the first fastener is screwed on the nuts and penetrates through the corresponding through holes to abut against the pile, the pile is clamped tightly by the first fastener through a plurality of second fasteners, the second fasteners are at least three, and the bottom end of the second fastener abuts against the end part of the pile, the length of each second fastening piece in the sleeve cap can be adjusted by adjusting the second fastening pieces, so that the fixed seat can be adjusted to be in a horizontal state, and the fixed seat is ensured to be in the horizontal state, so that a guide rod arranged on the fixed seat is not inclined;
providing a drilling tool assembly, wherein the drilling tool assembly comprises a drill bit arranged corresponding to the first through hole, the drill bit is matched with the pile core, the drilling tool assembly is movably arranged on the guide rod, the guide rod is sleeved with a shell fixedly connected with the drilling tool assembly, a worm extending out of the shell is arranged in the shell in a penetrating manner, a shaft rod is fixedly arranged in the shell, a worm wheel meshed and connected with the worm is sleeved on the shaft rod, a rack is arranged along the length direction of the guide rod, the rack is meshed and connected with the worm wheel, the worm wheel is driven to rotate by rotating the worm, the worm wheel can move along the length direction of the rack, and then the drilling tool assembly can move along the length direction of the guide rod, so that the drill bit can extend into the pile core to clean the pile core; and
cleaning the core by moving the drill assembly along the guide rod such that the drill bit extends into the core;
the drilling tool assembly comprises a shell fixedly connected to the shell and a motor installed in the shell, the drill bit is hollow, the bottom end of the drill bit is open, a drainage tube is provided, the drainage tube penetrates through the shell and the motor and extends into the drill bit, when the drill bit rotates, water flowing out of the drainage tube is sprayed on the inner wall of the drill bit and flows to the bottom end of the drill bit through water injection into the drainage tube, and the water at the bottom end of the drill bit rotates along with the rotation of the drill bit and is sprayed to wash and clean the pile core;
and a level gauge is arranged on the casing, and the level gauge detects whether the casing is in a horizontal state or not, so that whether the drill bit is in a vertical state or not is judged.
