Abstract
The housing contains a mechanism for absorbing the drive return force, together with a smoothing head for shaping the face of the cladding, on the shield for constructing tunnels. The shaping device has a contouring component (6) on the same axis in the housing (1), able to swivel with the housing during pressing, and then to be offset along the shield's longitudinal axis, on completion of a section. A rear support component (7) is displaceable along the longitudinal axis of the cladding (3). This prevents fissure formation in concrete, and ensures waterproof tunnel cladding.
