Abstract
In the cutter shield used for driving cavities in the ground, thrust-piston mechanisms (17) supported on the common supporting frame (10) lie protected in the interior of the driving cutters (11). Brackets (31) for attaching the piston rods (20) of the thrust-piston mechanisms (17) are arranged at the rear end of the supporting frame (14). The piston rods (20), with the arrangement of a seal (24), are led out at the rear from the interior spaces (16) of the driving cutters (11) and are attached to the brackets (31) of the supporting frame (14). Consequently, a cutter shield which is of short construction and is therefore readily controllable can be created, contamination and jamming of the thrust-piston mechanisms (17) being avoided at the same time.
