Patent ID: 6896071

Claim:
A drive system for driving a sheet pile member at a desired location in the ground comprising: a source of pressurized air; an actuator system defining a drive axis, the actuator system comprising a housing assembly having an inlet port connected to the source of pressurized air; and a piston member adapted to move along the drive axis relative to the housing assembly; and an adapter member rigidly connected to the housing assembly, where the adapter member defines a plurality of pairs of guide slots and each pair of guide slots is configured to accommodate a different type of sheet pile member; whereby the sheet pile member is arranged at the desired location; the adapter member is arranged such that the first and second guide slots at least partly receive portions of the sheet pile member; the pressurized air causes the piston member to move along the drive axis; and the piston member impacts the sheet pile member as the piston member moves along the drive axis, thereby displacing the sheet pile member along the drive axis into the ground at the desired location.
