Abstract (en)
[origin: WO2011015711A1] A helical flange equipped pile drivable into the ground, which in a screwing process pulls itself into the ground, such that the displaced volume of soil is less than the soil volume loosened by the flange in its drilling process, wherein the material of a pile shaft 6 is reinforced concrete, having some of its reinforcement (4, 5) or the like high-tension-resistant structure provided in a helix-shaped spiral (5) or shell, which is attached to pile driving elements and to a segment (3) associated with the helical flange, such that the rotation, established in the process of driving the helical flange into the ground, generates on the helix-shaped segment a tensile force which further generates a compressive force on the concrete.
