Abstract
L'invention concerne un outil d'excavation qui comprend : un tube de forage, un trépan annulaire de grand diamètre disposé de manière coaxiale côté extrémité distale du tube de forage, et un trépan pilote inséré dans le trépan annulaire à travers l'intérieur du tube de forage. Une tête de trépan dont le diamètre se dilate lorsqu'elle est tournée dans une direction de rotation de l'outil pendant l'excavation est montée sur une partie circonférentielle externe au niveau de l'extrémité distale du trépan pilote. Le trépan annulaire comprend : une mise en prise qui vient en prise avec la tête de trépan déployée dans la direction de rotation de l'outil et une première partie de butée qui peut venir en butée contre la tête de trépan dans la direction axiale.
