step two: the hoisting ring is externally connected with a crane, the gravel pile shell is lifted upwards, then the gravel pile shell is moved to the upper part of the gravel pile placing pit, and the gravel pile shell is placed in the gravel pile placing pit;
step three: the external controller controls the motor mechanism and the electric hydraulic mechanism, and the motor mechanism is started to drive the stabilizing column to rotate;
step four: starting the electric hydraulic mechanism to drive the rotating stabilization column to move downwards, so as to drill out a reinforcement pit;
step five: and cutting off the electric wires connected with the motor mechanism and the electric hydraulic mechanism, separating the crane from the lifting ring, and enabling the lifting ring to fall into the lifting ring placing shell.
