Panels which are driven into ground with press used in trench digging

摘要

The holes (15) in the panels extend only through part of the thickness of the panel. Bolts which are inserted in the holes engage with a beam (3) on a press with which the panels are either driven into or extracted from the ground. Instead of with round holes, the bolts (41) can engage with cutouts which are formed by a groove in the side of the panel and by blocks which have been welded into the groove to separate the cutouts. These cutouts also do not pass through the panels. The edges of the panels, which are stacked on top of one another have matching V-shaped cross-sections or other interlocking sections.
