Title: CLAMPING ADAPTER AND METHODS FOR SONIC PILE DRIVING
Abstract:
A pile driving adapter (10, 10a) includes an upper attachment portion (20, 20a) for selectively attaching the adapter (10, 10a) to a drill head (12) and a lower housing portion (22) including at least a first outer wall (50). The pile driving adapter (10, 10a) further includes at least one actuator (90, 92) including a first portion (110) slidably mounted to the lower housing portion (22) and a second portion (112) configured to expand from the first portion (110) in a direction perpendicular to the first outer wall (50). The first portion (110) may be slidably mounted to the lower housing portion (22) via a sliding mount (100, 102), and the lower housing portion (22) may include at least one elongate slot (180, 182) for receiving at least a portion of the sliding mount (100, 102). The pile driving adapter (10, 10a) advantageously couples the drill head (12) and the member to be driven so as to reliably transfer sonic energy.
