Abstract

The invention relates to a method for constructing a foundation for a tower structure, comprising at least one structure-side connection profile in the form of a pipe segment. The method has the steps of providing a foundation pile with a diameter which differs from the diameter of the pipe segment, vibrating and/or ramming the foundation pile into a supporting substratum, aligning and fixing the pipe segment coaxially and concentrically to the foundation pile introduced into the substratum such that an annular space is formed between the pipe segment and the foundation pile, and filling the annular space with a curable casting compound.

First claim

What is claimed is:

1. A method for constructing a foundation for a tower structure having at least one structure-side connection profile in the form of a pipe segment, wherein the method comprises the following steps:
supplying a number of foundation piles selected from a group comprising tubular profiles, T-shaped profiles, I-shaped profiles, Z-shaped profiles or other sheet-pile-wall segments;
driving the number of foundation piles into a load-bearing foundation soil, wherein the driving-in method is selected from a group comprising introduction by vibration, ramming or drilling or combinations thereof, wherein the number of foundation piles are driven into the foundation soil over a circular arc, the circular arc arranged coaxially in relation to a longitudinal axis of the tower structure;
orienting and securing the pipe segment coaxially in relation to the circular arc of the number of foundation piles;
partially filling the pipe segment with a settable casting compound; and
wherein the pipe segment is supported on the number of foundation piles prior to partially filling the pipe segment with the settable casting compound.

2. The method as claimed in claim 1 , wherein the pipe segment is oriented and secured coaxially in relation to the circular arc of the foundation piles such that a center of the pipe segment is coaxial with the center of the circular arc of the number of foundation piles, and the settable casting compound has an annular shape.

3. The method as claimed in claim 1 , further comprising at least one supporting bracket, which supports the pipe segment on at least one of the foundation piles of the number of foundation piles.

4. The method as claimed in claim 1 , wherein the number of foundation piles are each of a flange-free design.

5. The method as claimed in claim 1 , further comprising at least one spacer which orientates the pipe segment.

6. The method as claimed in claim 1 , wherein the pipe segment and the circular arc each have a diameter, and the diameter of the pipe segment is greater than the diameter of the circular arc of the number of foundation piles.

7. The method as claimed in claim 1 , wherein the foundation is constructed onshore.

8. The method as claimed in claim 1 , wherein the pipe segment is supported on the number of foundation piles at a distance from the foundation soil.

9. An onshore tower structure comprising:
a structure-side connection profile in the form of a pipe segment, and
a number of foundation piles driven into a foundation soil and selected from a group comprising tubular profiles, T-shaped profiles, I-shaped profiles, Z-shaped profiles or other sheet-pile-wall segments,
wherein the pipe segment and the number of foundation piles surround one another to form an annular space, and
wherein the pipe segment is at least partially filled with a set casting compound, and
wherein the pipe segment is fastened on at least one of the number of foundation piles at a distance from the foundation soil and/or the pipe segment is supported on at least one of the number of foundation piles via at least one supporting bracket.

10. The onshore structure as claimed in claim 9 , wherein the number of foundation piles are each of a flange-free design.

11. A method for constructing a foundation for a tower structure having at least one structure-side connection profile in the form of a pipe segment, wherein the method comprises the following steps:
supplying a number of foundation piles selected from a group comprising tubular profiles, T-shaped profiles, I-shaped profiles, Z-shaped profiles or other sheet-pile-wall segments;
driving the number of foundation piles into a load-bearing foundation soil, wherein the driving-in method is selected from a group comprising introduction by vibration, ramming or drilling or combinations thereof, wherein the number of foundation piles are driven into the foundation soil over a circular arc, the circular arc arranged coaxially in relation to a longitudinal axis of the tower structure;
orienting and securing the pipe segment coaxially in relation to the circular arc of the number of foundation piles;
partially filling the pipe segment with a settable casting compound; and
wherein the pipe segment is supported on the number of foundation piles at a distance from the foundation soil.
