Patent ID: 7972083

Claim:
A system for aligning a pile during pile driving, comprising: a pile having a laterally protruding coupling for a tether; and a pile guide for supporting the pile as it is driven into a substrate, comprising a base frame and a pile guide member mounted on the base frame, characterised in that the pile guide member has in its periphery a slot which is configured to allow the laterally protruding coupling to pass therealong as the pile is guided through the pile guide; and in that the pile and pile guide member comprise two pairs of slidably interfitting profiles which are configured to resist gaping of the slot of the pile guide member as the pile is driven therethrough into the substrate, wherein the pile guide member has a longitudinal axis, wherein the slot has two laterally spaced-apart edges relative to the longitudinal axis of the pile guide, wherein, during pile driving, one pair of the slidably interfitting profiles is laterally spaced-apart from the other pair of slidably interfitting profiles relative to the longitudinal axis of the pile guide member such that one pair of the slidably interfitting profiles is near one edge of the slot and the other pair of slidably interfitting profiles is near the other laterally spaced-apart edge of the slot.
