Larssen sheet piling

History
Larssen sheet piling has been used since 1912 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 of the fenced area.

Instructions
Dowels may be connected in section two or three of the tongue. Length rebates can reach 34 meters. Also, the hat profile is Z-shaped and flat tongues have locks.

Separate dowels, during pile diesel hammers or vibrators, turn relative to each other by 180°, and connect by inserting a dowel into the adjacent side slot (lock). The fully assembled structure is a steel wall that can be formed in 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, with tongues and produced plastics.

Design
Tongue Larssen - Tongue Larssens are up to 34 meters long and 80 centimeters wide. They have locks, which allow people to connect one profile to another vertically to create a sealed metal diaphragm wall. Contractor selection presented dowels hot and cold rolling with different transverse profile, such as S, Z, L, Ω (Omega) - a deep trough or Ω - shallow trough.
Special Profile - Special profiles are long, but narrow metal profiles without locks, which allows to create a wall of metal in the soil. They usually have a wavy or trough shape to increase the resistance to bending. Piles groovy - lists Larsen sheet piling, welded to each other, for example in the root volume profile, wide flat profile, etc..
Cantilever Wall Design - Bending moments and shears
are calculated under the assumption that the wall is a cantilever beam fixed at the bottom of the wall.

Anchored Wall Design- Bending moments, shears,
and anchor force are calculated under the assumption that the Wall is a beam with simple supports at the anchor elevation and at the bottom of the wall . With the bottom of the wall at the penetration consistent with a factor of safety of 1, the lateral reaction at the bottom support will be zero and the lateral reaction at the upper support will be the horizontal component of the anchor force.

Application
Foundation pits, strengthening coastlines, construction of bridges, piers and other work requiring the use of rebates or Larssen sheet piles are the most expensive work to strengthen the soil at penetrations open method because of the need to use large masses of sheet piling.
