Method and apparatus for inserting sheet piles within an earth formation

摘要

A method and apparatus for inserting a sheet pile (10) into an earth formation utilizing a protective housing (12) releasably connected to the sheet pile (10). The driving force exerted by a vibrator hammer (58) or drop hammer is applied against the protective housing (12) which in turn applies the driving force against the upper end of the sheet pile (10) for driving the sheet pile (10) into the formation. Movable flaps (28, 29) on the lower end of the housing (12) pivot inwardly to engage the lower end of the sheet pile (10) for releasably connecting the protective housing (12) to the sheet pile (10).
