After the concrete is submerged to a certain height, the pouring of concrete is stopped.

[0072] The driving mechanism 5 is started in reverse, the clamping assembly 8 and the close-fitting assembly 7 are forced to retreat under the action of the telescopic assembly 6, the lifting mechanism 3 is started, the support assembly 4 is forced to move upward, and the pouring assembly 9, the clamping assembly 8 and the close-fitting assembly 7 are forced to move upward synchronously until the output pipe 903 is exposed from the surface of the poured concrete.

[0073] The driving mechanism 5 is started again, the corresponding positions of the reinforcement cage are clamped by the clamping assembly 8 and the close-fitting assembly 7 under the action of the telescopic assembly 6, and the process is repeated in sequence, so that the device is continuously lifted, the different height positions of the reinforcement cage are clamped, the pouring of concrete into the pile hole is continuously performed, until the pile hole is completely poured to form a pile foundation, thereby realizing the control of the reinforcement cage, and the device is lifted away from the pile foundation by using the lifting device.

[0076] When the reinforcement cage is lowered, the lifting mechanism 3 is started, the lifting mechanism 3 forces the support assembly 4 to slowly descend, forces the telescopic assembly 6, the close-fitting assembly 7 and the clamping assembly 8 to descend, until the reinforcement cage is lowered to the bottom of the pile hole, the lowering work of the reinforcement cage is completed, the reinforcement cage is ensured to be vertically lowered along the pile hole, and the phenomenon that the reinforcement cage is skewed during lowering is reduced;

[0077] When the concrete is poured, the driving mechanism 5 is started, the bottom of the reinforcement cage is clamped by the clamping assembly 8 and the close-fitting assembly 7 under the action of the telescopic assembly 6, the concrete is poured into the pile hole by the pouring assembly 9, and the pouring of the concrete is stopped after the concrete is submerged to a certain height;
