The OPEN CELL® bulkhead, used primarily on such structures as coffer-dams and docks, is a cellular flat sheet pile structure in which each cell’s sheet piles are driven in the shape of a U when viewed from above. This system functions as a horizontally tied membrane, relying solely on the vertical soil-friction flat sheet pile anchor wall to restrain a curved flat sheet pile arch face. The bulkhead becomes a series of U-shaped horizontal member structures that need no toe embedment for stability.
