[0002] Pile drivers are important mechanical equipment that occupy a dominant position in construction projects such as foundation piling, photovoltaic column piling, and guardrail piling. With the advancement of technology, the number of piling methods has gradually increased, such as drilling and grouting piling, prefabricated pile driving, etc., which are no longer limited to a single piling method. Pile drivers are usually composed of pile hammers, pile frames and ancillary equipment. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. according to the power source of the movement. Modern pile drivers have appeared in many different styles to adapt to different foundation construction environments. Pile drivers have been widely used in pile foundation construction of modern building bridge projects.

[0003] Most of the existing pile drivers are single-function and can only perform pile driving or drilling.
