Abstract (en)
[origin: EP2390419A2] The machine (10) has a ground perforation tool i.e. vibratory needle (26), with an upper end (26a) connected to a supply unit made of construction material e.g. concrete, and a lower end (26b) with an orifice (28) to set the material. A tank (30) receives another construction material e.g. ballast. The tank is mounted at a lower end (18a) of a mast (18), and extended around the tool, so that the tool is slid via the tank. The tank has a truncated cone shaped lower end with an opening to dump the latter material. An introducing unit e.g. traction cable and gear, introduces tank in ground (S). An independent claim is also included for a method for realizing columns in the ground.
