Abstract: A sheet pile module with at least three sheet piles including a central sheet pile, wherein the central sheet pile has a first coupling segment with a first coupling feature along a first longitudinal edge, a second coupling segment with a second coupling feature along a second longitudinal edge that is opposite and parallel to the first longitudinal edge, and an intermediate segment between and connected to the first coupling segment and to the second coupling segment, a first U-sheet or Z-sheet pile is connected to the first coupling feature, and a second U-sheet or Z-sheet pile is connected to the second coupling feature.
