摘要

For the emergency sealing of the circular gap between the shield tail and the lining elements or tubbing, it is proposed to pass liquid nitrogen through pipes (4) running in an annular shape to the area of the circular gap. To this end, the shield tail area, in the area of the seals (2), carries pipes (4) having the appropriate connections. After icing over, damaged seals (2) can be renewed or repaired without risk.
