ABSTRACT:
Yet another embodiment of the present disclosure relates to a sheet pile installation apparatus for inserting a sheet pile vertically into a soil formation, the installation apparatus including an elongated body configured to releasably receive the sheet pile, the body having an upper end, a lower end, a lower edge, a top surface, a bottom surface, and at least one aperture formed at said lower end. The installation apparatus further includes a catch having a first portion and a second portion, the catch being pivotally mounted in the aperture about said pivot axis such that the first portion and the second portion are disposed on opposed sides of the lower end of the body when the catch is in an at-rest position. The first portion of the catch is configured such that insertion of the body into the soil formation rotates the first portion upwardly such that the first portion engages a lower end of the sheet pile disposed adjacent the top surface of the body.
