  2. Caisson (engineering) - Wikipedia

    en.wikipedia.org/wiki/Caisson_(engineering)

    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.

  3. Suction caisson - Wikipedia

    en.wikipedia.org/wiki/Suction_caisson

    Suction caissons (also referred to as suction anchors, suction piles or suction buckets) are a form of fixed platform anchor in the form of an open bottomed tube embedded in the sediment and sealed at the top while in use so that lifting forces generate a pressure differential that holds the caisson down.

  4. Caisson (lock gate) - Wikipedia

    en.wikipedia.org/wiki/Caisson_(lock_gate)

    Rolling caissons are a development of sliding caissons fitted with rollers beneath. These do not rely solely on buoyancy to make them portable and so are easier to operate. [7] The caisson may only need to be lifted a few inches to make it movable on its track, which significantly reduces the ballast pumping time compared to a ship caisson.

  5. Caisson lock - Wikipedia

    en.wikipedia.org/wiki/Caisson_lock

    The caisson lock is a type of canal lock in which a narrowboat is floated into a sealed watertight box and raised or lowered between two different canal water levels. It was invented in the late 18th century as a solution to the problem posed by the excessive demand for water when conventional locks were used to raise and lower canal boats ...

    en.wikipedia.org/wiki/History_of_decompression...

    1841 – Jacques Triger documented the first cases of decompression sickness in humans when two miners involved in pressurised caisson work developed symptoms. [2] 1847 – The effectiveness of recompression for the treatment of decompression sickness (DCS) in caisson workers was described by B. Pol and T.J. Watelle. [2] [3]

  8. Breakwater (structure) - Wikipedia

    en.wikipedia.org/wiki/Breakwater_(structure)

    A breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass (e.g. with caissons), or by using a revetment slope (e.g. with rock or concrete armour units). In coastal engineering, a revetment is a land-backed structure whilst a breakwater is a sea-backed structure (i.e. water on both sides).

  9. Limbers and caissons - Wikipedia

    en.wikipedia.org/wiki/Limbers_and_caissons

    Horse artillery—rows of limbers and caissons, each pulled by teams of six horses with three postilion riders and an escort on horseback (1933, Poland). A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed.
