    摘要： Tunnel driving apparatus incorporates a cutter shield with a plurality of drive members or cutters arranged side-by-side in a cylindrical array. The drive members are supported and guided for individual longitudinal displacement on a cylindrical continuous cowl or casing forming at least part of a support frame. Rams which serve to shift the drive members and the frame are coupled therebetween and extend through sealed openings in an end wall of a recess formed on the exterior of the cowl and open towards the drive members.To facilitate the creation of a concrete lining for the tunnel behind the cutter shield, a rear shield is formed by reduced rearwardly extending tails of the drive members. A further cylindrical casing locates within the rear shield and supports a pair of annular rings. One of these rings combines with a sheathing extending inside the further casing and the rear shield to form a concrete reception space. The other ring is fixed to the further casing and locates with piston and cylinder units operable to move the further casing and the rings relative to the frame of the cutter shield. To enable the interior of the cutter shield to be maintained at excess pressure, the rings engage with slidable seals on the rear shield and on the sheathing while a further slidable seal is provided between the further cowl and the casing of the cutter shield frame.

    摘要： In tunnel construction with shield drive locational concrete is brought in stages directly behind the shield as tunnel lining. In order not to have to interrupt the shield progress during concreting it is proposed to provide a shield tail element consisting of a plurality of lamina movable relative to the shield, in addition to a shield tail element attached rigidly to the shield. This basically stands still during the continuous progress of the shield and is drawn forward into the shield by lamina only during the segment concreting, in order to remain immobile there relative to the earth until the next concreting stage.

    摘要： A sealing means is provided for sealing against passage of liquid between two surfaces, as between the tail-piece of a tunnelling machine and the tunnel lining to prevent ingress of working liquid into the tunnel workings, said sealing means comprising a mount for flexible fibers projecting brush-like therefrom, the mount being fixed in substantially liquid-tight manner to one said surface, such as that of a tail-piece, and arranged to permit said fibers to extend into contact with the second surface, such as that of the tunnel lining. The free ends of at least a portion of the fibers preferably extend parallel with the second surface and in contact with one another and/or that surface. Flexible sheeting may be arranged in combination with the fibers substantially to close off said space and inflatable air-bag means may be interposed between the free ends of the fibers (fiber/sheeting combination) and the first surface to increase the pressure of contact between the fibers and the first surface.
