ABSTRACT:
A pile splice includes two splice plates, each having a dove-tail shaped groove aligned with the groove in the abutting plate. Slip cams are disposed in the channel, defined by the grooves, for outward movement to draw the plates together. Drive wedges are driven between the slip cams to drive them outwardly to draw and hold the plates together and to form a massive, strong pile splice. Wedge forces are distributed to increase clamping forces. Headed reinforcing bars are securely held in the splice plates by plastic bushings to facilitate splice plate alignment and pile casting. Methods are provided.
