Abstract (en)
[origin: EP0974732A1] For the continuous tunneling work through loose rock, using ring segments to be assembled into rings (1), in the first step with extended leader presses (7) and withdrawn telescope presses (8) and retracted press shields (11), the telescope presses (8) are extended and the leader presses (7) are withdrawn. In the next step, after the press shield (11) has been advanced and positioned at the tunnel wall, the leader presses (7) are extended for the next advance. The telescope presses (8) are operated to be followed by the assembly of a further ring (1).
