Abstract

L'invention concerne un procédé et un dispositif pour évacuer des déblais au cours du creusement d'un tunnel. Ledit dispositif comporte un système de fermeture (27) servant à séparer un premier segment et un second segment d'un ensemble vis sans fin (19, 31). Ainsi, lors d'un creusement ouvert ou d'un creusement par pression de terre, lorsque le système de fermeture (27) est fermé, les déblais sont évacués par une première ouverture (22) ménagée en amont du système de fermeture (27) dans le sens de l'évacuation, tandis que, lors d'un creusement par pression de boue, lorsque la première ouverture (22) est fermée et que le système de fermeture (27) est ouvert, les déblais peuvent être introduits dans le second segment.
