s2, sleeving a reinforcement cage: sleeving a custom reinforcement cage mould (9) on the part of the reinforcement cage extending out of the ground, wherein the requirement is that hoop reinforcing ribs of the reinforcement cage extend into hoop rib clamping steps (93) of the custom reinforcement cage mould (9) and rubber ring layers (92) which are in direct contact with a plurality of groups of vertical reinforcement bars are extruded to form a stable connecting structure;
s3, detecting an offset position: the damping outer bearing (1) on the outer side of the custom reinforcement cage mould (9) rotates around the reinforcement cage, whether the adjacent reinforcement cage points are vertical or not is detected by the deflection measuring instrument (4) in the rotating process, and when the deflection measuring instrument (4) detects that the deflection of the reinforcement cage points at a certain position in the rotating range is not vertical, the rotation is stopped immediately;
s4, inserting a bullet lock cylinder (15): inserting the bullet lock column (15) into the supporting plate (5) and the through hole (10) of the spring steel clamping piece (6) until two groups of inner grooves (16) of the bullet lock column (15) open the clamping feet (7) of the spring steel clamping piece (6) and then locking;
s5, adjusting a lifting column: the height of the lifting column (20) is adjusted to enable the connecting rod (12) and the damping outer bearing (1) to keep the same horizontal state, and a constructor treads the pedal plate (23) by using feet to enable the whole device to be fixed on the bottom surface of the outer side of the filling pile;
s6, correcting the deviation by the regulator: the anti-slip adjusting head (88) is screwed by hand to drive the rotating shaft (87) to rotate, so that the pinion (86) drives the large gear (85) to rotate in a decelerating way, the screw rod (81) rotates to cause the screw rod moving seat (17) on the screw rod (81) to move linearly and move slightly, and the screw rod moving seat (17) moves slightly to drive the damping outer bearing (1) and the customized reinforcement cage mould (9) to move along, so that the reinforcement cage in the steel cage corrects the deflection angle, and the correction effect is achieved;
s7, disassembling: then through rotating the adjusting bearing (13), the baffle seat (31) rotates 90 degrees from the position adsorbed by one group of limiting sheets (30) to the position adsorbed by the other group of limiting sheets (30), so that the spring steel clamping sheet (6) is unhooked and separated from the bullet head lock column (15), and the disassembling effect is achieved.
