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 ...
Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1] Driving methods such as open-ended coring, rock socketing, and composite shaft construction are occasionally used to overcome unique site problems. [3]
Tracked vehicle configured as a dedicated pile driver. A pile driver is a heavy-duty tool used to drive piles into soil to build piers, bridges, cofferdams, and other "pole" supported structures, and patterns of pilings as part of permanent deep foundations for buildings or other structures. Pilings may be made of wood, solid steel, or tubular ...
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 ...
Upon installation, tiebacks are tested and usually pre-loaded. In specific, a combination of proof tests and performance tests are performed on every job. Proof testing involves the application of successively larger loads on the tieback with a loading jack, allowing for the recording of a load-elongation curve according to gauge readings.
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 ...
Composite or synthetic shingles are a relatively new type of shingle material that are made from a blend of materials, including asphalt, fiberglass, and other polymers. These shingles are designed to mimic the look of natural materials such as wood, slate, or clay and aim to increase the durability, strength, and resistance to weather elements ...
Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. [1] The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and ...
