A sunk panel of ceilings or soffits.
A watertight box or cylinder used in excavating for foundations or tunnel pits to hold out water so concreting or other construction can be carried on.
A 10" or 12" diameter hole drilled into the earth and embedded into bedrock three to four feet; servers as structural support for a type of foundation wall, porch, patio, etc. Two or more "sticks" of reinforcing bars (rebar) are inserted into and run the full length of the hole and concrete is poured into the caisson hole
A cylindrical shaft drilled into competent material, at which depth the bottom of the shaft is sometimes reamed, or belled, into a conical shape to provide a larger base for foundation support. The shaft is reinforced with steel and filled with concrete.
watertight structure with work carried on inside to block the entrance of a canal or dock, or a box with an open top fastened to the side of a ship for hull repairs
an ornamental sunken panel in a ceiling or dome
large watertight chamber used for construction under water
a huge box made of steel-reinforced and waterproof concrete with an open central core
a large cylinder or box chamber that is sunk into the riverbed
a large, usually bottomless box or cylindrical shell, made of wood, concrete or steel, which is used in the construction of foundations located in water or below the ground-water level
a water-tight box, usually of sheet iron, and constructed so that it
A watertight, dry chamber in which people can work underwater
A 10" or 12" diameter hole drilled into the earth and embedded into bedrock 3 - 4 feet. The structural support for a type of foundation wall, porch, patio, monopost, or other structure. Two or more "sticks" of reinforcing bars (rebar) are inserted into and run the full length of the hole and concrete is poured into the caisson hole.
underwater housing for structure or foundation.
The commonly used name for a cylindrical casing which becomes the structural support for a piling. The piling is inserted and concrete is usually poured into the casing. Used in areas where it may be impossible or impractical to drive piling alone without this extra support. Example.
a watertight chamber used in construction work under water or as a foundation
A pressurized, bell-shaped structure which allows construction fully under the water. Compare with cofferdam.
A boatlike structure used to seal a dry dock so that water can be pumped out and maintenance and repair work carried out on ships
A drilled pier which aids in supporting foundation walls, posts, and other structures.
A hollow, watertight box which is used to construct and mold pier foundations in water channels. The caisson is sunk where the pier is to be constructed and eventually becomes part of the pier itself.
A watertight structure within which construction work is carried on under water
a watertight chamber used to install the foundation of a structure
A structure or chamber in water well construction which is usually sunk or lowered by digging from the inside.
A casing sunk or constructed below ground or water level.
In engineering, a caisson is a retaining, watertight structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. These are constructed so that the water can be pumped out so the working environment is dry. When piers are to be built using the open caisson and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation.
