Abstract

Outil de forage rotatif à molettes. Cet outil comporte au moins une buse d'irrigation du front de taille située entre deux molettes et au moins une buse créant au-dessus des molettes un jet ascendant pour l'entraînement des déblais. Il est caractérisé en ce que la buse d'irrigation présente au voisinage de sa base au moins deux ouvertures adaptées à produire des jets fluides respectivement dirigés vers les deux molettes entre lesquelles est située cette buse d'irrigation. Application au forage du sol.
