Abstract: To simplify the production and expand the variability of structures to use, a grooved sheet pile having a trough-type body is produced by cutting a cylindrical segment (referred to as a troughlike element) (1) from a round tube along its length and fixing locking elements (2) and (3) to side edges of the troughlike element. The troughlike element (1) can be reinforced by attaching reinforcing elements (4) thereto and/or providing annular elements (15), (16). The troughlike element (1) has a section made of material of higher strength and/or corrosion-resistant and/or thickened material. The troughlike elements (1) can be arranged in parallel and fixed to each other to make a panel.

Abstract: The inventive grooved sheet pile having a though-type body is produced by cutting a cylindrical segment (1) from a round tube along the length thereof, and fixing locking elements (2 and 3) to the side edges of said segment. The segment (1) can be cut together with an annular section (15) of a tube (16) and reinforced by fixing elements (4), an internal (5) or external (6) strap, internal (8 and 9) and/or external (10 and 11) faceplates or stiffening ribs fixed thereto. Said segment can be embodied from sections of cylindrical segments welded to each other. At least one section (18) has an increased thickness or is made of a corrosion-resistant material. In order to produce an enlarged grooved pile, two or more cylindrical segments (1) cut from a tube are used. Said segments are disposed in a parallel position with respect to each other and fixed to each other with the aid of reinforcing elements (12, 13, and 14). The locking elements (2 and 3) are fixed to the lateral side of the thus obtained panel.
