Abstract (en)
[origin: CA2906244A1] 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.
