Abstract
A drive system for driving a sheet pile member at a desired location in the ground. The drive system comprises a source of pressurized air, an actuator system defining a drive axis, and an adapter member. The actuator system comprises 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. The adapter member is rigidly connected to the housing assembly. The adapter member further defines at least a first pair of first and second guide slots. In use, 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. 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.
