Abstract

The invention relates to a method for manufacturing a sheet pile wall component such as a sheet pile, a connection profile or a carrier that exhibits at least one interlock with a uniform cross-section extending across the entire length of the sheet pile wall component for engaging the interlock of an additional sheet pile wall component. According to the invention, a preliminary product is produced by forming using this method, and the interlock when viewed in its cross-section is manufactured at least in sections by shape-cutting at the section of the preliminary product that is to be provided with the interlock, whereby the cross-section of the section is dimensioned sufficiently such that the dimensional deviations caused by forming at the preliminary product are taken into account for the shape-cutting of the interlock.

Claims

1. A method for manufacturing a sheet pile wall component which exhibits at least one interlock with a uniform cross-section extending across the entire length of the sheet pile wall component, for engaging the interlock of an additional sheet pile wall component, said method comprising the steps of:

Producing a preliminary product through forming, and shape-cutting the interlock, when viewed in its cross-section, at the section of the preliminary product that is to be provided with the interlock, wherein the cross-section of the section is dimensioned sufficiently such that the dimensional deviations caused by forming at the preliminary product are taken into account for the shape-cutting of the interlock.

2. A method as set forth in claim 1, wherein a material accumulation is formed during the forming of the preliminary product at the section that is to be provided with the interlock and the interlock is produced by shape-cutting from the material accumulation, whereby the cross-section of the material accumulation is dimensioned such that the dimensional deviations that occur through forming at the preliminary product are taken into account for the shape-cutting of the interlock.

3. A method as set forth in claim 2, wherein the material accumulation is molded during the forming of the preliminary product such that the material accumulation is adapted to the shape of the interlock to be produced when viewed cross-sectionally.

4. A method as set forth in claim 3, wherein the section of the preliminary product that is to be provided with the interlock or the material accumulation that is molded at the preliminary product is formed to the final interlock shape after shape cutting at least in sections, when viewed cross-sectionally.

5. A method as set forth in claim 4, wherein the area of the section that is still to be formed after shape-cutting to form the final interlock shape or the material accumulation is heated to a heat forming temperature.

6. A method as set forth in claim 1, wherein shape-cutting of the interlock is carried out through several chip-removing tools, preferably in several successive processing steps.

7. A method as set forth in claim 1, wherein shape-cutting is performed using at least one cutting tool with a geometrically defined cutting edge.

8. A method as set forth in claim 1, wherein the preliminary product with its material accumulation is guided past a stationary processing station for shape-cutting.

9. A method as set forth in claim 1, wherein the interlock is created using a mobile processing station.

10. A method as set forth in claim 1, wherein shape-cutting is carried out through form-milling and/or form-grinding.

11. A method as set forth in claim 1, wherein shape-cutting is carried out immediately following the forming of the preliminary product.

17. A method as set forth in claim 1, wherein shape-cutting is performed using at least one cutting tool with a geometrically undefined cutting edge.

12. A sheet pile wall component which exhibits at least one interlock with a uniform cross-section extending across the entire length of the sheet pile wall component for engaging the interlock of an additional sheet pile wall component, the improvement wherein the sheet pile wall component is produced by forming and wherein the at least one interlock is produced at least in sections by shape-cutting.

13. A sheet pile wall component as set forth in claim 12, wherein a material accumulation is formed at the section of the sheet pile wall component that is provided with the interlock, and wherein said interlock is formed in said material accumulation through shape-cutting.

14. A sheet pile wall component as set forth in claim 13, wherein the interlock is formed into its final interlock shape after shape-cutting through subsequent forming.

15. A sheet pile wall component as set forth in claim 14, wherein the formed interlock is selected from the group consisting of a Larssen interlock, a Hoesch claw, a Hoesch button, a ball interlock, a socket interlock, a flat profile interlock, a trapezoidal groove, a trapezoidal interlock, a trapezoidal flange and a dovetail groove.

16. A sheet pile wall component as set forth in claim 12, wherein the sheet pile wall component is a wedge-shaped carrier.
