APPARATUS FOR POSITIONING A SINKING TUNNEL SECTION
A positioning apparatus includes a frame and two substantially vertically extending legs. The frame includes a suspension device adapted to suspend a sinking tunnel section. The legs include upper ends connected by a substantially horizontally extending beam and lower ends vertically movable relative to the sinking tunnel section. The legs include clamping members for engaging opposite transverse sides of the tunnel section that are settable substantially in a plane defined by the legs and beam of the frame. The frame is devised for extending with its legs outwardly of the two opposite transverse sides of the tunnel section and extending with the beam above a roof of the tunnel section.
