Abstract

L'axe XX du corps F de la foreuse définit l'axe d'enfoncement Le moteur d'entraînement, situé à la partie supérieure, entraîne, à vitesse convenable, les forets A1, A2 par l'intermédiaire d'éléments d'engrenages depuis l'arbre 42. Au moins deux des forets sont décalés de l'axe Des dispositifs de refoulement mettent la boue de forage en circulation. La surface extérieure du corps comporte des saillies qui servent au guidage du corps en même temps qu'à l'équilibrage du couple de forage pour empêcher la rotation des forets décalés autour de l'axe XX. Au moins trois des forets sont disposés selon un contour fermé pour détacher une masse ou carotte de terrain à extraire.
