Abstract
A foundation driller for anchoring of components in soil is provided that includes an apparatus in which the foundation driller comprises a base body with at least one cylindrical area and at least one cutting blade that provides forward advancement, in which the base body comprises at least two cylindrical areas with different diameters, wherein the area nearer to the soil has a smaller diameter and the at least one cutting blade providing forward advancement is attached at the area nearer to the soil and has an even incline.
Claims18
A screw-in ground anchor for anchoring structural elements in soil, the screw-in ground anchor comprising:
- a base member including at least three regions having at least two cylindrical regions and at least one conical region wherein said at least three regions are arranged so that there are alternating cylindrical and conical regions with decreasing size in the direction towards the ground;
- and
- at least one cutting blade that produces forward motion,
- wherein each of the at least one cutting blade extends over only one of said cylindrical regions and does not extend over and does not extend beyond an extent of said one cylindrical region and does not extend over any region which has a conical shape,
- wherein the at least one cutting blade that produces forward motion is produced by forging or a casting process, is attached to the lower cylindrical region, and has a uniform pitch, and
- wherein a filling of a curable material is introduced into the upper cylindrical region of the base member, in which material a support is fastened directly or indirectly.
A screw-in ground anchor for anchoring structural elements in soil, the screw-in ground anchor comprising:
- a base member having an open bottom end and including at least three regions having at least two cylindrical regions and at least one conical region wherein said at least three regions are arranged so that there are alternating cylindrical and conical regions with decreasing size in the direction towards the ground;
- and
- at least one cutting blade that produces forward motion,
- wherein each of the at least one cutting blade extends over only one of said cylindrical regions and does not extend beyond an extent of said one cylindrical region and does not extend over any region which has a conical shape,
- wherein the cutting blade that produces forward motion is composed of a plurality of individual cutting blades, which include segments that are arranged on a thread pitch or next to one another at a height, and
- wherein a filling of a curable material is introduced into the upper cylindrical region of the base member, in which material a support is fastened directly or indirectly.
