For the tubulose screw rod basis of anchoring, such as the component on ground, have the matrix with cylindrical region and multiple sand spades of the circumference by surrounding screw rod basis at tunnel element.

摘要

The present invention relates to a base (1) for anchoring of components in the ground, which has at least one cylindrical area and generating a forward movement of the cutting blade, in particular according to prior art de 102008011869.The object of the invention is to provide a base (1), in which an adaptation to different soil conditions is possible.According to the invention, the object is achieved with an arrangement, in which the propulsion of the cutting blade (2.1) which generates on a sleeve (2) is mounted, which can be releasably connected to the base body (1) of the screw is connected to the foundation and the base body (1) is provided with three cylindrical regions (1.1, 1.2, 1.3) with different diameters, wherein the near-earth regions (1.3) the smallest diameter and the upper region (1.2) has the largest diameter and the propulsion of the cutting blade (2.1) which generates on the central region (1.1) is mounted.
