Abstract (en)
The installation has a translation displacement head sliding along a vertical mast for driving a kelly (18) along a vertical direction. A soil drilling and mixing head (20) is fixed to lower end of kelly, where the head (20) has rotating tools (22, 24) whose axles are parallel between them and parallel to horizontal direction. Flaps (50, 52) are mounted at end of the kelly for controlling angulation of the head (20) with respect to the vertical of the head (20) around an axis orthogonal to the direction. An independent claim is also included for a method of correcting trajectory of mixing and drilling head of a buried wall making installation.
