A construction method for pile driving using a vibratory pipe pile driver

This invention relates to a construction method for driving piles using a vibratory driven pile unit. The original walking pile frame is replaced with a crawler crane. Utilizing the flexible movement of the crawler crane, the machine can move immediately after driving one pile to drive the next. At this time, crushed stone can be added to the previous pile, and then the pile can be extracted. This back-and-forth operation greatly improves construction efficiency. The crawler crane is equipped with an adjustment frame, which is fixed at the bottom by a bottom-fixing cylinder. The mast adjusts the upper position of the pile frame, and the adjustment frame adjusts the lower position of the pile frame, ensuring the verticality of the crushed stone piles during driving and extraction. During use, the mast adjusts the position of the pile frame, and the vibratory lifting mechanism drives the hoisting rope to move the vibratory hammer up and down through the slide frame for driving or extracting piles.
