<p>The pile driver (1) assembly consisting of a plurality of pile driver units (2) interconnected together to a rigid base frame (3) that uses the push and pull method to drive a group of raked piles. The pile driver units(2) progressively push one pile (5) at a time for a short distance into the ground while being pull down by the rest of the stationary driven piles (5) in a repeated cyclical driving sequence until the required pile driving force is reached for every pile in the group. The pile driver (1) assembly consists a plurality of interconnected pile driver units (2), a pile driver base adaptor (4), a pile clamping system (7) and strong base frame (3) to drive all the piles (5) in a two dimensional array of variously raked pile group from IV: 1H to true vertical in the z-axis and rotated to any angle in the x-y plane at a minimum pile's spacing of three times the pile's diameter.</p> |
