Abrégé

An apparatus for positioning a sinking tunnel section comprises a frame (1) with two substantially vertically extending legs (2) which at their upper ends are connected by a substantially horizontally extending beam (3). The frame is devised for extending with its legs outwardly of two opposite transverse sides (4) of the tunnel section and extending with its beam (3) above the roof (6) of the tunnel section. The frame is provided with suspension means (7) from which the tunnel section can be suspended. The lower ends of the legs are vertically movable relative to the sinking tunnel and the legs each are provided with clamping members (14) for engaging said opposite transverse sides (4) of the tunnel section. The clamping members are settable substantially in the plane defined by the legs and beam of the frame.
