Patent number: 9157208Abstract: A pile driver assembly consisting of a plurality of pile driver units interconnected together to a rigid base frame that uses the push and pull method to drive a group of raked piles. The pile driver units progressively push one pile at a time for a short distance into the ground while being pull down by the rest of the stationary driven piles in a repeated cyclical driving sequence until the required pile driving force is reached for every pile in the group. The pile driver assembly consists a plurality of interconnected pile driver units, a pile driver base adaptor, a pile clamping system and strong base frame to drive the piles in a two dimensional array of variously raked pile group from 1V: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.Type: GrantFiled: June 14, 2012Date of Patent: October 13, 2015Inventor: Chin Chai Ong

Patent number: 9151010Abstract: An article for joining concrete piles having an annular plate mounted at one end of the pile, a central opening, a front surface an obverse surface and an interlocking profile having a plurality of first and second complementary configurations. Each configuration is defined in a substantially equalized sector and arranged radially in an alternate fashion on the front surface, the first configuration is a protrusion and the second configuration is a recess, wherein the lateral edges of each protrusion carries a horizontally extending groove. When mating of two identical articles, each mounted at the ends of two separate piles, the protrusions of one article mate with the recesses of another article forming of a passageway by two adjacently positioned grooves of two contiguous protrusions of the mated articles, the passageway allows interlocking of the mated articles by inserting a pin there through.Type: GrantFiled: September 13, 2013Date of Patent: October 6, 2015Inventor: Chin Chai Ong

Patent number: 8827336Abstract: A pile clamp assembly to clamp a pile that consists of the following main components; top pile clamp device, the bottom pile clamp device, a plurality clamp wedges and a plurality vertical hydraulic clamps which combines to make a flat clamp wedge contact with the surface of a deviated and twisted pile. This clamping mechanism reduces bending in the driven pile by enabling the next adjoining pile to conform as much as possible to the alignment of the existing driven pile and gradually corrects the pile's vertical alignment and twist as it penetrates the ground through interactions of the unique swiveling clamp wedges.Type: GrantFiled: May 23, 2011Date of Patent: September 9, 2014Inventor: Chin Chai Ong
