Larssen sheet piling was developed in 1906 by Tryggve Larssen, engineer from Bremen (Germany). [ 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 ...
Sheet piles are used to restrain soft soil above the bedrock in this excavation. Sheet piling is a form of driven piling using thin interlocking sheets of steel to obtain a continuous barrier in the ground. The main application of sheet piles is in retaining walls and cofferdams erected to enable permanent works to proceed. Normally, vibrating ...
One approximate relationship between SPT N-value, relative density, and bulk density for coarse-grained material can be seen in the table below. This is cited in the US Army Corps of Engineers engineering manual publication on sheet pile design developed after Terzaghi and Peck (1948) and Teng (1962). [2]
These cofferdams are typically a conventional embankment dam of both earth- and rock-fill, but concrete or some sheet piling also may be used. Usually, upon completion of the dam and associated structures, the downstream coffer is removed and the upstream coffer is flooded as the diversion is closed and the reservoir begins to fill.
Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
A steel sheet pile being hydraulically pressed. Hydraulic press-in equipment installs piles using hydraulic rams to press piles into the ground. This system is preferred where vibration is a concern. There are press attachments that can adapt to conventional pile driving rigs to press 2 pairs of sheet piles simultaneously.
Bored pile retaining wall in Lisbon, Portugal. Bored pile retaining walls are built by assembling a sequence of bored piles, followed by excavating away the excess soil. Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer.
Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering, hydrogeology or soil mechanics as a first check for problems of flow under hydraulic structures like dams or sheet pile walls. As such, a grid obtained by ...
