Larssen sheet piling is a kind of sheet piling retaining wall. Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending. The segments are typically made of steel or another metal. [1]
Larssen sheet piling was developed in 1906 by Tryggve Larssen. [2] [3] [4] Its applications include piers, oil terminals, waste storage facilities, shoreline protection, [5] bridges, houses, buildings, dry docks other construction sites and for the strengthening of pond banks, preventing slumping into a pit and flooding. [6] [7] [8]
Lengths can reach 36 meters.
Each segment is flipped 180° versus the preceding segment. The segments lock together using a variety of interconnections. [9]
The fully assembled structure is formed in a linear, circular, or other shape.
To reduce the filtering space, mixed sealant is injected. Additionally, it may be combined with the use of dowels, metal beams and pipes. [10]
Metal dowels are hot-rolled steel and cold-rolled.
Larssens are used in foundation pits, coastline strengthening, bridge construction, piers, tide control, flood protection, agriculture irrigation, water reservoir and other work requiring extremely strong support in a narrow geometry.
