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 ...
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.
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 hammer, t-crane and crawle drilling are used to establish sheet piles. [citation ...
Cofferdams are commonly used for construction or repair of permanent dams, oil platforms, bridge piers, etc., built within water. They also form an integral part of naval architecture. These cofferdams are usually welded steel structures, with components consisting of sheet piles, wales, and cross braces. Such structures are usually dismantled ...
Heavy construction equipment is usually used due to the amounts of material to be moved — up to millions of cubic metres. Earthwork construction was revolutionized by the development of the scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.
Screw piles are typically manufactured from high-strength steel [1] using varying sizes of tubular hollow sections with helical flights. The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft to suit the site specific ground conditions. Helices can be press-formed to a specified pitch or ...
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]
EN 1993-5 gives design rules for steel sheet piling and bearing piles to supplement the generic rules in EN 1993-1 and is intended to be used with Eurocodes EN 1990 - Basis of design, EN 1991 - Actions on structures and EN 1997-1 for Geotechnical Design.
