Abstract

Drilling device for in situ mixing of soil with a binder to form a pile in the ground, comprising a drivable shaft with a bottom end, pre-mixing means mounted at the bottom end of the shaft for loosening the soil, injection means for injecting the binder into the loosened soil, a bore-crown mounted on the shaft above the bottom end, which bore-crown is provided on at least a part of its periphery with cutting means, wherein the pre-mixing means for loosening the soil comprise at least one arm having a first and a second end, said first end being connected at one end to the bottom end, said second end lying at a distance of the bore-crown, the distance between the second end and the shaft being smaller than the radius of the bore-crown, wherein said at least one arm is provided with teeth.
