A caisson is sunk by self-weight, concrete or water ballast placed on top, or by hydraulic jacks. The leading edge (or cutting shoe) of the caisson is sloped out at a sharp angle to aid sinking in a vertical manner; it is usually made of steel.
Caisson, in engineering, boxlike structure used in construction work underwater or as a foundation. It is usually rectangular or circular in plan and may be tens of meters in diameter. Learn more about caissons, including various types of the structure.
A caisson is a specialized type of watertight retaining structure used to create deep foundations for large structures. The term is derived from the French word for “box,” which accurately describes its function as a prefabricated or constructed enclosure designed to exclude water and soil materials during excavation.
“Caisson” comes from the French word for “box.” In operation, the shell acts as an impermeable, bottom-open chamber that can be placed underwater while keeping the interior dry.
In Civil Engineering, Caissons denote watertight structures which are constructed in connection with the excavation for foundations of bridges, piers, abutments in river and lake dock structure, foreshore protection, etc. The caisson remains in its pose and thus ultimately becomes as integral parts of the permanent structure.
In construction, a caisson is a watertight structure used to work on the foundations of a bridge, pier, or other construction projects that require working underwater.
A caisson is a watertight retaining structure used as a foundation element. Caissons are large, hollow cylinders made of materials such as concrete, steel, or wood, and are typically sunk into the ground to reach bedrock or stable soil.
