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 ...
A heavily damaged piling structure can be reinforced by cutting out the damaged section and replacing it with preservative-treated wood. [14] Wrapping piles with plastic barriers can provide protection from marine borers for 25 years or more. [14] Pile reinforcement with concrete can be sufficient by filling the void with coarse stone and ...
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.
Construction workers who leave the pressurized environment of the caisson must decompress at a rate that allows symptom-free release of inert gases dissolved in the body tissues if they are to avoid decompression sickness, a condition first identified in caisson workers, and originally named "caisson disease" in recognition of the occupational ...
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 ...
Screw piles, sometimes referred to as screw-piles, screw piers, screw anchors, screw foundations, ground screws, helical piles, helical piers, or helical anchors are a steel screw-in piling and ground anchoring system used for building deep foundations. Screw piles are typically manufactured from high-strength steel [1] using varying sizes of ...
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.
