Abstract

L'invention concerne un tube de forage utilisé pour produire un forage dans un sol d'un point de départ à un point d'arrivée le long d'une ligne de forage prédéfinie, en particulier pour la pose de câbles enterrés ou de canalisations enterrées dans le sol à proximité de la surface. Le forage est creusé au moyen d'un dispositif de forage muni d'un outil de forage permettant de désagréger le sol lors de l'avance du tube de forage, le tube de forage présentant respectivement à ses extrémités au moins une section de raccordement permettant de l'assembler de manière amovible et résistante à la traction à au moins un autre élément d'une tige de forage. Le tube de forage présente au moins un élément permettant de produire un assemblage résistant à la traction avec un élément correspondant d'un dispositif d'avance permettant d'avancer et/ou de reculer le tube de forage dans le trou de forage, et une paroi extérieure du tube de forage est réalisée d'un seul tenant. L'invention concerne par ailleurs un dispositif servant à introduire au moins un tube de forage dans un trou de forage et de l'en retirer, ainsi qu'un système et un procédé afférents.
