摘要： The invention relates to a machine (10) for making columns in ground, the machine comprising a carrier (12) having a mast (14) extending along a longitudinal direction; a movable carriage (16) mounted to slide along the mast (14); a ground perforation tool (20) extending along a longitudinal axis parallel to said longitudinal direction and secured to said movable carriage, presenting a top end connected to building material feed means, and a bottom end provided with an orifice (28) for injecting the first building material; a rotary drive system (18) for driving the perforation tool (20) in rotation; and a body (40) extending around the perforation tool (20) so that the perforation tool is suitable for sliding through said body. According to the invention, the machine has a coupling system (60) for coupling together the body (40) and the perforation tool (20) in translation and in rotation.

摘要： A device (10) for treating a portion of soil comprises a rotary shaft (20), at least one deployable mixer tool (40) secured to the rotary shaft (20), and a longitudinal pipe (22) for injecting a fluid in the proximity of the mixer tool (40). According to the invention, the treatment device (10) further includes a boring tool (24) situated at the bottom end of the shaft (20), an outer tubular element (30) extending parallel to the rotary shaft (20), the rotary shaft (20) being arranged inside said tubular element (30), and a coupling system (50) between the rotary shaft (20) and the tubular element (30). In a first configuration, the coupling system (50) is suitable for constraining the tubular element (30) and the rotary shaft (20) to move together in rotation about the main axis (X), in at least one direction of rotation, and for constraining the tubular element (30) and the rotary shaft (20) to move together in translation along the main axis (X), at least in the downstream direction. These movements in rotation and translation can be released in a second configuration of the coupling system (50).
