METHOD AND DEVICE FOR POSITIONAL STABILISING OF TUNNEL LINING ELEMENTS

摘要

The invention relates to a method for positional stabilising of tunnel lining elements (2) applied in tunnel tubes (1) over the region adjacent to the shield tail (8) of the driving shield of a tunnel boring machine in which the backfilling (10) and stabilising are carried out. A retaining construction (5) is detachably connected to the inner surfaces (7) of the tunnel lining elements (2) to exert a tensile force, which is exerted in an essentially radially symmetrical fashion in the tunnel tubes (1) and to hold the tunnel lining elements (2) in the set position, wherein the detachable connection between the tunnel lining elements (2) and the multi-part retaining construction (5) is essentially maintained by a vacuum relative to the external air pressure or by a magnetic field acting on the reinforcements in the tunnel lining elements (2).
