Abstract

L'invention concerne un procédé et un ensemble de forage pour introduire une tige de forage avec une orientation correcte dans le sol. Ce procédé consiste à déterminer une orientation de la position de la tige de forage au moins au début de l'introduction, à ajuster ensuite l'orientation de la tige de forage au moyen d'un dispositif de réglage commandé par l'intermédiaire d'une unité de commande puis à introduire la tige de forage dans le sol au moyen d'un dispositif de forage. Selon l'invention, dans une zone de tête de la tige de forage sont disposés un élément de marquage et, de manière axialement opposée, un dispositif de mesure indépendant de la tige de forage, qui présente au moins deux unités de mesure de distance. Les unités de mesure de distance mesurent régulièrement la distance axiale par rapport à l'élément de marquage pendant le forage, chaque unité de mesure de distance fournissant des valeurs de mesure indépendantes. Ces valeurs de mesure de distance sont comparées dans l'unité de commande et utilisées pour ajuster la tige de forage pendant le forage.
