[0066] Specifically, the first vertical lifting piece of the mobile lifting assembly is controlled to rise to axially lift the T-shaped sliding rail 2 of the annular assembly along the outer periphery of the pile foundation steel bar cage until the steel bar extruder 25 is located at a distance of 20-30 cm from the lower end of the extrusion sleeve 18 on the pile foundation steel bar 23.

[0067] Step 3: The pile foundation steel bar 23 is fixed by controlling the radial positioning assembly of the steel bar to move along the radial direction of the annular assembly.

[0068] Specifically, before fixing, it is ensured that the radial positioning assembly of the steel bar and the pile foundation steel bar 23 are radially opposite in sequence, and then the first horizontal telescopic cylinder 8 is controlled to drive the sliding rod 4 to move along the translation sliding sleeve 5, so that the U-shaped clamping groove 11 at the front end of the sliding rod 4 nests the outer periphery of the pile foundation steel bar 23, and then the top wire 9 on both sides of the U-shaped clamping groove 11 is locked to fix the U-shaped clamping groove 1 and the pile foundation steel bar 23.

[0069] Step 4: The extruder moving assembly is controlled to move along the circumferential direction of the annular assembly at intervals, and the movement is stopped when the steel bar extruder 25 is radially opposite to the pile foundation steel bar 23; within the interval time when the radial positioning assembly of the steel bar stops moving, the steel bar extruder 25 is controlled to move to the connecting position of the pile foundation steel bar 23 to extrude and connect the pile foundation steel bar 23.

[0070] Specifically, the driving reducer 17 of the reinforcing steel radial positioning assembly drives the sliding wheel 22 to move along the outer periphery of the T-shaped slide rail 2. During the movement, the reinforcing steel position sensor detects the position of the pile reinforcing steel 23 in real time. When the reinforcing steel extrusion machine 25 is radially opposite to the pile reinforcing steel 23, the reinforcing steel position sensor detects the pile reinforcing steel 23. At this time, the reinforcing steel position sensor sends a signal to the controller 27, and the controller 27 controls the driving reducer 17 to stop running for a period of time and then continue to run to the position of the next pile reinforcing steel 23. The above process is repeated in sequence.

[0071] The reinforcing steel position sensor can sequentially detect the positions of the pile reinforcing steels in sequence, or can sequentially detect the positions of the pile reinforcing steels and then control the driving reducer to stop. The specific method depends on the connection height of the extrusion sleeve of the pile reinforcing steel.

[0072] When the connection heights of the extrusion sleeves of the pile reinforcing steels 23 are spaced and layered, that is, the connection positions of the extrusion sleeves of the pile reinforcing steels arranged in odd numbers (first, third, fifth, seventh, etc.) are the same, and the connection positions of the extrusion sleeves of the pile reinforcing steels arranged in even numbers (second, fourth, sixth, eighth, etc.) are the same. At this time, the reinforcing steel position sensor is controlled to stop after sequentially detecting the positions of the pile reinforcing steels arranged in odd numbers (first, third, fifth, seventh, etc.), and then the reinforcing steel position sensor is controlled to stop after sequentially detecting the positions of the pile reinforcing steels arranged in even numbers (second, fourth, sixth, eighth, etc.).

[0073] As a preferred embodiment, the reinforcing steel position sensor sequentially detects the positions of the pile reinforcing steels in sequence, that is, when the position of the first pile reinforcing steel is detected, the second vertical lifting cylinder 12 is controlled to rise to the position where the reinforcing steel extrusion machine 25 reaches the axial extrusion connection position of the extrusion sleeve 18, and then the second horizontal telescopic cylinder 16 is controlled to move horizontally to drive the reinforcing steel extrusion machine 25 to reach the radial extrusion connection position of the extrusion sleeve 18, and finally the reinforcing steel extrusion machine 25 is controlled to start extruding the extrusion sleeve 18 to connect the pile reinforcing steel. After the connection of the first pile reinforcing steel is completed, the second horizontal telescopic cylinder 16 returns to the original position, and the second vertical lifting cylinder 12 remains stationary. The driving reducer 17 continues to start until the reinforcing steel position sensor detects the position of the third pile reinforcing steel, and then the reinforcing steel position sensor sends a signal to control the driving reducer 17 to stop. Then the second horizontal telescopic cylinder 16 is controlled to move horizontally to drive the reinforcing steel extrusion machine 25 to reach the radial extrusion connection position of the extrusion sleeve of the third pile reinforcing steel, and then the reinforcing steel extrusion machine 25 is controlled to start extruding the third pile reinforcing steel. After the extrusion connection of the third pile reinforcing steel is completed, the second horizontal telescopic cylinder 16 returns to the original position, and the second vertical lifting cylinder 12 remains stationary. The above process is repeated in sequence to complete the connection of the pile reinforcing steels arranged in odd numbers (first, third, fifth, seventh, etc.). After the connection of the pile reinforcing steels arranged in odd numbers is completed, the above process is repeated to complete the connection of the pile reinforcing steels arranged in even numbers (second, fourth, sixth, eighth, etc.).

[0074] Of course, it can also be selected that when the steel bar position sensor detects the pile steel bar position in turn, that is, after the extrusion connection of the first pile steel bar is completed, the second horizontal telescopic cylinder 16 and the second vertical lifting cylinder 12 are simultaneously controlled to return to the original position, and then reach the extrusion sleeve extrusion connection position of the second pile steel bar, and then the second vertical lifting cylinder 12 and the second horizontal telescopic cylinder 16 are controlled to move in turn to complete the connection of the second pile steel bar, and then the second horizontal telescopic cylinder 16 and the second vertical lifting cylinder 12 are controlled to return to the original position again; in turn, the extrusion connection of the third, fourth, fifth, sixth, seventh, eighth... pile steel bars is sequentially completed.
