发明名称 METHOD AND DEVICE FOR TRANSPORTING OVERBURDEN AWAY DURING TUNNELLING
摘要 A method and device for transporting overburden away during tunneling includes a seal that separates a first portion and a second portion of a transporting screw arrangement. As a result, in open tunneling or in earth-pressure-assisted tunneling, when the seal is closed, overburden can be transported out of a first opening, arranged ahead of the seal in the direction of removal and, in fluid-assisted tunneling, when the first opening is closed and the seal is open, the overburden can be transported into the second portion.
