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. Larssen sheet piling was developed in 1912 for use in the construction of piers, oil terminals, waste storage facilities, bridges, houses, buildings, other construction sites and for the strengthening of pond banks, preventing slumping into a pit and flooding. ==Construction== Lengths can reach 34 meters. Each segment is flipped 180° versus the preceding segment. The segments lock together using a variety of interconnections. 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. Metal dowels are hot-rolled and cold-rolled. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Larssen sheet piling」の詳細全文を読む スポンサード リンク
