Abstract

The invention relates to a foundation pile comprising a stabilization device that is located within the foundation pile and is connected to at least two inner surface sections of the foundation pile; the stabilization device allows compressive and/or tensile forces to be transmitted such that the stabilization device counteracts lateral deformation and/or torsional deformation of the foundation pile.

First claim

The invention claimed is:

1. A foundation pile ( 10 ), comprising:
a stabilization device ( 30 ; 31 - 38 , 39 _ 1 , 39 _ 2 , 39 _ 3 ) arranged within the foundation pile ( 10 ) and connected to at least two inner surface sections ( 11 ) of the foundation pile ( 10 ), wherein compressive and/or tensile forces can be transmitted by means of the stabilization device ( 30 ; 31 - 38 , 39 _ 1 , 39 _ 2 , 39 _ 3 ) configured to distribute wind, wave or tidal force within the foundation pile ( 10 ) when anchored in the seabed to provide a lateral stiffness and/or torsional stiffness of the foundation pile ( 10 ); and
wherein the stabilization device ( 30 ; 31 - 38 ) comprises at least two connected stabilization struts ( 31 - 38 ), two opposite ends of which are connected to two inner surface sections ( 11 ) of the foundation pile ( 10 ).

2. The foundation pile ( 10 ) of claim 1 , wherein the stabilization device ( 30 ; 31 - 38 , 39 _ 1 , 39 _ 2 , 39 _ 3 ) comprises a stabilization ring ( 39 _ 1 , 39 _ 2 , 39 _ 3 ) arranged within the foundation pile ( 10 ) and connected to at least two inner surface sections ( 11 ) of the foundation pile ( 10 ).

3. The foundation pile ( 10 ) of claim 1 , wherein
the stabilization device ( 30 ; 31 - 38 ) comprises at least two stabilization struts ( 31 - 38 ), components of extent of which do not extend parallel to one another, at least in some section or sections; and
respective ends of the stabilization struts ( 31 - 38 ) are each connected to one inner surface section ( 11 ) of the foundation pile ( 10 ).

4. The foundation pile ( 10 ) of claim 1 , wherein
the stabilization device ( 30 ; 31 - 38 ) comprises at least three stabilization struts ( 31 - 38 ), respective pairs of components of extent of which do not extend parallel to one another; and
respective ends of the stabilization struts ( 31 - 38 ) are each connected to one inner surface section ( 11 ) of the foundation pile ( 10 ).

5. The foundation pile ( 10 ) of claim 1 , wherein
the stabilization device ( 30 ; 31 - 38 ) comprises four stabilization struts ( 31 - 38 ), respective pairs of which do not extend parallel to one another; and
a first stabilization strut ( 31 - 38 ) and a second stabilization strut ( 31 - 38 ) define a first plane, and a third stabilization strut ( 31 - 38 ) and a fourth stabilization strut ( 31 - 38 ) define a second plane, wherein the first plane and the second plane enclose an angle.

6. The foundation pile ( 10 ) of claim 1 , wherein the stabilization struts ( 31 - 38 ) are connected to one another.

7. The foundation pile ( 10 ) of claim 1 , wherein
the stabilization device ( 30 ; 31 - 38 ) comprises eight stabilization struts ( 31 - 38 ); wherein two of the stabilization struts ( 31 - 38 ) in each case extend axially offset and in a collinear manner relative to one another, thus forming four stabilization strut pairs which do not extend parallel to one another;
a first stabilization strut pair and a second stabilization strut pair define a first plane, and a third stabilization strut pair and a fourth stabilization strut pair define a second plane, wherein the first plane encloses an angle with the second plane; and
the foundation pile ( 10 ) furthermore comprises a connecting device ( 40 ) for connecting the stabilization struts ( 31 - 38 ), wherein the connecting device ( 40 ) has eight receptacles ( 41 ) for respectively accepting one end of a stabilization strut ( 31 - 38 ), wherein the axial extents of two receptacles ( 41 ) in each case extend parallel to one another.

8. The foundation pile ( 10 ) of claim 1 , further comprising at least two foundation pile segments ( 20 ), wherein longitudinal axes of the respective foundation pile segments ( 20 ) extend in a substantially collinear manner relative to one another.

9. The foundation pile ( 10 ) of claim 8 , wherein the two foundation pile segments ( 20 ) are connected to one another by means of the stabilization device ( 30 ; 31 - 38 , 39 _ 1 , 39 _ 2 , 39 _ 3 ).

10. The foundation pile ( 10 ) of claim 8 , wherein the foundation pile segments ( 20 ) are each formed by at least two partial-cylinder segments ( 24 ) connected to one another by means of the stabilization device ( 30 ; 31 - 38 , 39 _ 1 , 39 _ 2 , 39 _ 3 ).

11. The foundation pile ( 10 ) of claim 10 , wherein longitudinal edges ( 21 ) of the mutually adjacent partial-cylinder segments ( 24 ) of the foundation pile segment ( 10 ) are spaced apart, with the result that the foundation pile ( 10 ) has through openings ( 14 ) between these longitudinal edges ( 21 ) of the partial-cylinder segments ( 24 ).

12. The foundation pile ( 10 ) of claim 1 , further comprising fastening devices ( 50 ) arranged on the inside of the foundation pile ( 10 ), wherein the stabilization device ( 30 ) is fastened on the fastening devices ( 50 ).
