AI Technical Summary
The existing PHC pipe pile driving equipment has poor accuracy in desert areas, which makes PHC pipe piles prone to tilting in soft soil and reducing stability.
A high-frequency hydraulic vibratory hammer combined with a limit rod and support plate structure is used. A servo motor drives a screw rod and a bevel gear transmission system to achieve the positioning and fixation of PHC pipe piles and prevent tilting.
It improves the accuracy of pile driving equipment, ensuring that PHC pipe piles do not tilt when inserted into soft soil, thus guaranteeing the stability of the pipe piles.
