Abstract

For installing panels consisting of diaphragm portions and reinforcements into recesses in the ground a deflection body is provided which is movable along the opening of the ground recess, the upper surface of the deflection body being curved so that the panels can be inserted into a suspension in the ground recess via the deflection body without discontinuities and without bending the panels over a deflection radius smaller than the smallest possible bending radius of the panels. Welding machines are disposed on the deflection body for joining the panel sections transversely and longitudinally to form a web having a length which corresponds to the depth of the suspension filled recess in the ground.
