Abstract

L'invention a pour but de vérifier la verticalité d'un forage ou d'un puits 1. Une jauge 13 est descendue et centrée au fond du forage par un câble 12. On met le câble sous tension au moyen d'un treuil 14, puis on déplace la poulie 15 jusqu'à constater, au moyen d'un niveau 106, la verticalité du câble 12. On mesure ensuite l'écart 17 entre le câble et l'axe du forage, ce qui est représentatif de l'obliquité du forage. Application au contrôle des forages au cours de l'excavation en présence de boue à la bentonite.
