A system for assembling a cofferdam. In a first example embodiment, a cofferdam may be assembled on-site using a plurality of walls that couple each other to form the cofferdam. In a second example embodiment, a plurality of walls and a plurality of connectors may be assembled to form the cofferdam. The walls and/or connectors disassembled for transport and/or storage, yet quickly assembled on-site to form the cofferdam. The panels and/or the connectors may form cofferdams of various shapes and sizes. The walls and/or connectors are made of a durable material that permits multiple uses. The cofferdam may be assembled to hold back the water of a body of water from around a culvert while work or repairs are performed.

A pipe pile, for use in a foundation or a retaining wall, comprises a substantially cylindrical, and preferably steel, pipe body extending longitudinally between two opposite ends, the pipe body being formed of a plurality of pipe sections, interlocked or welded together end-to-end and arranged on a common central longitudinal axis between the two ends. All of the pipe sections have substantially the same outside diameter; however, two or more pipe sections have differing inside diameters, and thus a differing wall thickness, between the two ends of the pipe pile.

The invention relates to a profiled connection section with a constant cross-section for coupling at least two Larssen sheet piles (Sx, Sy, Sz) at an angle of 90°, comprising two identically designed hooked strips (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106). Each hooked strip (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106) has a hook-shaped hook section (16), a lock base (18, 24; 50; 68, 70; 88; 110) which adjoins one end of the hook section (16) and runs in a straight manner, and a stop (20, 26, 48, 52; 72, 74; 86, 90; 108) which adjoins the lock base perpendicularly to the lock base (18, 24; 50; 68, 70; 88; 110). The free end of the hook section (16) together with the stop (20, 26; 48, 52; 72, 74; 86, 90; 108) forms a lock jaw (24, 28; 54; 92) for hanging the sheet pile lock of the Larssen sheet pile (Sx, Sy, Sz), and when viewed in a cross-sectional direction, each hooked strip (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106) has an imaginary anchor point (A, B, C) on which the main contact point of the lock profile of the sheet pile (Sx, Sy, Sz) is arranged in an ideal assembly position. According to the invention, the anchor point (A, B, C) of each hooked strip (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106) has a specified distance (Ay, Bxz, Cy) which is normal to the main direction (X; Y; Z) of the Larssen sheet pile (Sx, Sy, Sz) hung on the respective other hooked strip (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106) in the ideal assembly position, wherein the distances between the anchor points (A, B, C) normal to the main directions (X, Y, C) of the Larssen sheet piles (Sx, Sy, Sz) hung on the hooked strips (12, 14; 42, 44, 46; 62, 64, 66; 82, 84; 102; 104; 106) in the ideal assembly position are identical.
