Abstract
A foundation for an offshore structure, more particularly an offshore wind turbine structure, comprising: at least one tower-like foundation structure with a circumferential foundation wall extending in the longitudinal direction, the foundation wall being delimited at the lower end by a lower-end end face, the foundation wall being formed from a mineral construction material; and at least one binding element, which is formed from a metal material and is arranged on the lower-end end face, the length of the binding element from the lower-end face to a lower end of the binding element being at least 0.5 m.
Claims18
A foundation, comprising:
- at least one tower-shaped foundation structure with a circumferential foundation wall extending in a longitudinal direction, the circumferential foundation wall being bounded on an underside by an underside end face and the circumferential foundation wall formed of a mineral building material;
- at least one binding element formed of a metallic material and arranged on the underside end face;
- wherein a length of the at least one binding element from the underside end face to a lower end of the at least one binding element is at least 0.5 m;
- wherein the at least one binding element comprises a longitudinally extending circumferential tie-in wall which extends from the circumferential foundation wall;
- wherein the foundation is an offshore wind power structure foundation;
- and
- wherein the foundation is configured to be rammed and/or vibrated into a seabed.
A method to produce a foundation, comprising:
- providing on-shore a formwork, wherein the formwork has an annular gap from a first, upper end towards a second, lower end which remains constant;
- casting the formwork with a liquid mineral building material;
- curing the concrete such that the cured concrete mineral building material forms a tower-shaped foundation structure;
- and
- securing at least one binding element to the cured tower-shaped foundation structure;
- wherein the tower-shaped foundation structure has a circumferential foundation wall extending in a longitudinal direction, the circumferential foundation wall being bounded on an underside by an underside end face and the circumferential foundation wall formed of the mineral building material;
- wherein the at least one binding element is formed of a metallic material and arranged on the underside end face;
- wherein a length of the at least one binding element from the underside end face to a lower end of the at least one binding element is at least 0.5 m;
- wherein the at least one binding element comprises a longitudinally extending circumferential tie-in wall which extends from the circumferential foundation wall;
- wherein the foundation is an offshore wind power structure foundation;
- and
- wherein the foundation is configured to be rammed and/or vibrated into a seabed.
A binding element of a foundation, comprising:
- the binding element formed of a metallic material and having a length of at least 0.5 m;
- the binding element on an underside end face of a circumferential foundation wall of a tower-shaped foundation structure formed of a mineral building material of the foundation;
- wherein the binding element comprises a longitudinally extending circumferential tie-in wall which extends from the circumferential foundation wall;
- wherein the foundation is an offshore wind power structure foundation;
- and
- wherein the foundation is configured to be rammed and/or vibrated into a seabed.
