Improvements introduced in the devices intended to drill the land with extraction of land, characterized in that the extractor is suspended from a cable provided with an individual control and is dragged rotationally by the lower element of the helical outer tube by means of a device used for coupling and uncoupling at will these two organs, and because it eventually adapts to the base of the helical tube, during drilling, a cap that can be put on and removed from the outside, either the perforation intended for the construction of piles in situ and achieved by compression of the ground (understandable land) or by injection (incomprehensible land).
