Patent ID: 8096733

Claim:
A system for the insertion of curved sheet pile, the system comprising: a pile driver comprising: a head portion configured to connect to a unit of positioning machinery, said head portion defining a first fixed pivot element, said first fixed pivot element defining a pile driver axis of rotation about which said pile driver is rotatable; and a body portion having an upper support head and a lower drive head, said upper support head connected to said head portion, said lower drive head connected to said upper support head to define a second fixed pivot element, said second fixed pivot element defining an insertion axis, said lower drive head including a connection mechanism, said insertion axis being spaced from said connection mechanism by an insertion distance; and a section of curved sheet pile having a pile radius of curvature, said pile radius of curvature being substantially equal to said insertion distance, wherein, with said section of curved sheet pile secured to said connection mechanism, a point defining a center of said pile radius of curvature lies substantially on said insertion axis.
