ABSTRACT:
A protective housing (12) is provided for a sheet pile (10) and has a length extending beyond the upper end (10A) and lower end (10B) of the sheet pile (10). A separate force transmitting member (26) is mounted on the protective housing (12) and has a horizontal plate (28) engaging the upper end (10A) of the sheet pile (10) for driving the sheet pile (10) downwardly upon exertion of a downward force from a suitable power source (44) to force the protective housing (12) downwardly. To separate protective housing (12) from sheet pile (10) upon driving of the sheet pile (10) to a desired predetermined depth so that protective housing (12) may be withdrawn, a fluid pressure device (50) is mounted between protective housing (12) and the force transmitting member (26). Upon actuation of fluid pressure device (50), protective housing (12) is moved upwardly while sheet pile (10) remains in position thereby to initially break loose the protective housing (12). After the initial separation of protective housing (12) the protective housing (12) along with the force transmitting member (26) may be lifted upwardly for removal by a suitable overhead lift means such as a crane.
