Abstract

A device for uniting a residue sheet pile and a main sheet pile into an aggregate sheet pile wherein a lowermost sheet of the residue sheet pile rests upon and uppermost sheet of the main sheet pile includes a displacement device having a drive; and a rake displaceable by the displacement device along a displacement path in a pile slide-in direction from a first to a second position and from the second to the first position in a direction opposite to the slide-in direction. The residue sheet pile is seated with its undermost sheet on the rake in the second position thereof, and the main sheet pile is in engagement with the rake from below with the uppermost sheet thereof, in one phase of the pile uniting process. The rake has traversed the displacement path in the direction from the second to the first position thereof, in a final phase of the pile uniting process. The rake is formed of lattice bars having respective free ends extending in the slide-in-direction, and the free bar ends have a cross-section reducing in height substantially constantly in the slide-in direction; the reduction in cross section of the free ends of the lattice bars being such that when the residue sheet p…
