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.
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.
In modern caissons this is usually simplified to a single-curvature arch, rather than a compound curved hull. Some shipyards made a particular trade of building caissons or lock gates. Edward Finch's bridge works was established in Chepstow in the mid 19th century to build ironwork for Brunel's Chepstow Railway Bridge directly above it.
Caisson (French for "box") may refer to: . Caisson (engineering), a sealed underwater structure Caisson (vehicle), a two-wheeled cart for carrying ammunition, also used in certain state and military funerals
The caissons—always submerged, as at Combe Hay—were without bottoms and were arranged so that their sides dropped into deep underwater channels formed by "minor walls" inside the main walls. The vertical movement of the two caissons was effected by a balance pipe ("the channel of communication") passing under the lock floor between the two ...
Also called caissons, drilled shafts, drilled piers, cast-in-drilled-hole piles (CIDH piles) or cast-in-situ piles, a borehole is drilled into the ground, then concrete (and often some sort of reinforcing) is placed into the borehole to form the pile. Rotary boring techniques allow larger diameter piles than any other piling method and permit ...
One can walk through the four caissons. Two of the B1 type Phoenix breakwaters (73 and 74) were sold to Sweden in 1949, and towed in July. Raised from Arromanches, they were initially towed to Frihamnen port in Stockholm and moved on 20 September 1956 to the newly-built heat and power plant in Hässelby where they remain as of 2021. [2]
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.
