A-Jacks are a commercially made concrete product used in both open channel and coastal applications. They consist of two concrete T-shaped pieces joined perpendicularly at the middle, forming six legs. [1] They are a product owned and patented worldwide by Poseidon Alliance Ltd.
A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties. One of the earliest designs is the Tetrapod, invented in 1950.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod . Weighing up to 8 tonnes (8.8 short tons ), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.
The concrete elements may be reinforced or prestressed. Such modern bridges include girder , plate girder , and box girder bridges, all types of beam bridges. Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them.
The pier of a bridge is an intermediate support that holds the deck of the structure. It is a massive and permanent support, as opposed to the shoring , which is lighter and provides temporary support.
