Abstract (en)

[origin: EP0663475A1] The machine has two or more parallel shafts (1) equipped with rotary augers (2) with cutting heads (3) on their free ends, with the distance between the axes of the shafts smaller than the diameter of the augers. The shafts and augers have through channels (1a,5a) for delivering a fluid for mixing with the soil. The shafts and augers are in even numbers - at least four - and are situated, when viewed from above, at the corners of a regular polygon, such a hexagon or octagon. The machine is driven by a motor and reduction gear system (8,9) and is used e.g. suspended from a crane.
