Abstract

L'invention concerne une machine permettant de creuser des galeries, tunnels ou similaires. Cette machine comprend des outils travaillant par contre-dépouille, montés sur des bras qui pivotent dans le sens radial et sont situés sur une tête de travail rotative (3). Cette dernière est logée dans un bâti de machine (1) sur lequel est monté un support (21) pourvu de dispositifs de support réglables (25, 26). Il est possible de régler la position relative du support (21) et du bâti (1), dans le sens transversal de la machine, de façon à ce qu'ils forment un angle et /ou soient parallèles. Un procédé de modification ou de correction de la direction du creusement permet de commander les mouvements des bras des outils selon au moins deux cycles de travail successifs, de sorte que la machine, pendant un cycle de travail succédant à un autre cycle, creuse un profil, dont la position par rapport à l'axe longitudinal de la machine est différente de celle du profil creusé lors du cycle de travail précédent.
