Monopile foundation and monopile foundation installation for an offshore structure and method for establishing a monopile foundation installation

摘要

The invention relates to a monopile foundation (2) for an offshore structure, in particular for a wind power plant (W), with a foundation pile (3, 41, 74) for supporting the structure and a foundation pile (3, 41, 74) outside. subsequent foundation reinforcement (4,22,44,61), whereby the foundation reinforcement (4,22,44,61) has a collar (4,45,63,75), a collar (9,64,76) and at least one support ( 8), wherein the collar (4,45,63,75) is assigned to the foundation pile (3,41,74) and the collar (9,64,76) over the at least one support (8) to the outside of the collar ( 4,45,63,75) is held at a distance, the foundation pile (3,41,74) having a foundation section (GA) for introduction into the seabed (M) and a reinforcement section (VA) for connecting the foundation pile (3,41, 74) with the cuff (4,45,63,75) above the seabed (M) and wherein the collar (9,64,76) is designed for at least partial introduction into the seabed (M). So that a satisfactory foundation can be achieved for such foundation piles, it is provided that the foundation reinforcement (4,22,44,61) several, in particular two, three or four reinforcement elements ( 11, 12, 20, 21, 47, 48) and that the sides of the reinforcing elements (11, 12, 20, 21, 47, 48) which are adjacent to one another in the circumferential direction are designed for form-fitting, articulated and / or force-fitting connection to one another.
