发明名称 METHOD AND DEVICE FOR TRANSPORTING OVERBURDEN AWAY DURING TUNNELLING
摘要 In the case of a method and a device for transporting overburden away during tunnelling, a seal (27) that separates a first portion and a second portion of a transporting screw arrangement (19, 31) is provided. As a result, in open tunnelling or in earth-pressure-assisted tunnelling, when the seal (27) is closed, overburden can be transported out of a first opening (22), arranged ahead of the seal (27) in the direction of removal, whereas, when the first opening (22) is closed and the seal (27) is open, the overburden can be transported into the second portion in fluid-assisted tunnelling.
