	caisson - Encyclopedia.com
		The open caisson is a cylinder or box, open at the top and bottom, of size and shape to suit the projected foundation and with a cutting edge around the bottom.
		Workers leaving a pneumatic caisson after hours of labor under high pressure are given special decompression treatment to accustom them to the lower atmospheric pressure and thus to prevent caisson disease (see decompression sickness).
		Caissons are also sometimes used for closing the entrance to dry docks or as a substitute for gates in canal locks.

	Caisson - LoveToKnow 1911
		A caisson in this sense implies a case or enclosure of wood or iron, generally employed for keeping out water during the execution of foundations and other works in water-bearing strata, at the side of or under rivers, and also in the sea.
		An example of a caisson with a water-tight bottom is furnished by the quays erected alongside the Seine at Rouen, where open-timber caissons were sunk on to bearingpiles down to a depth of 94 ft. below low-water, the brick and concrete lower portions of the quay-wall being built inside them out of water (see Dock).
		The term caisson is sometimes applied to flat air-tight constructions used for raising vessels out of water for cleaning or repairs, by being sunk under them and then floated; but these floating caissons are more commonly known as pontoons, or, when air-chambers are added at the sides, as floating dry-docks.

	Caisson (engineering) Summary
		Hence, the condition became known as caisson disease, and later by deep sea divers as "the bends." The symptoms are the result of too rapid decompression as a person ascends to the surface from a great depth or pressure, due to the expansion of bubbles of air trapped in joints, muscles, or blood.
		Shallow caissons may be open to the air, while deep caissons to penetrate soft mud may be sealed at the top and filled with compressed air to keep water and mud out at depth.
		Caisson disease is so named since it appeared in construction workers when they left the caisson and had rapid decompression.

	Caisson Lighthouse Construction Types
		The caisson construction method for lighthouses is based on the idea developed by Lawrence Potts, an English physician and inventor, who in 1845 sank a section of hollow tubing from the surface of the ocean to the sea floor.
		The caisson lighthouse type used a large cast-iron cylinder, which was sunk on the bottom and filled with rock and concrete to form a foundation.
		Caisson lighthouses were more complicated and on average about four to five times more expensive to build than screw pile lighthouses, but they were better able to withstand the pressure of flowing ice.

		Caissons can be up to 10 m (up to 33 ft) in diameter and are usually made of concrete or steel.
		Some caissons are used only to provide a work space underground or underwater and are removed once the construction project is complete.
		Other caissons are designed to become part of the foundation; these caissons are sunk deep into the ground until they reach bedrock, then are filled with concrete (see Building Construction).

	Abstract B162: Performance of Suction Caisson Anchors in Normally Consolidated Clay
		Suction caissons are anchors that utilize the large water pressure in deepwater during anchor installation, making it an efficient and economic alternative to driven piles.
		The second prototype caisson was built from two thin tubes forming a double-walled caisson capable of providing separate measurements of the components of axial capacity.
		The external side friction during pullout of the caisson was observed to increase with setup time until the external excess pore pressures were practically dissipated, while the end bearing resistance was not affected by the setup time.

	Caisson Lock
		Assuming the caisson had a drop of 46 feet, the various levels (level of the spoil heap and upper pound water level) match near-perfectly.
		It was at this end of the trench that the original ground level was confirmed to be much as it is today, but that from this point northward the whole surface was found to have been lowered by stripping off between 2 to 3 feet of subsoil and underlying natural clay.
		The Caisson was apparently still open when the lock flight and pump were installed early in 1805, as shown on the early c.1804 map, but had disappeared by the time of the next datable map of the lock flight, c.1809.

		The caisson team, knowing they were "in a bind" for time, left Lee and the damaged caisson in the care of others to return to the stables with the five other horses, unhitched, and the section sergeant's horse.

	Lateral Resistance of Suction Caisson Anchors
		The suction caisson is a relatively short, large diameter, open-ended cylindrical pile that can provide ideal anchors for laterally moored production structures in the deepwater such as the Gulf of Mexico.
		For the analysis, the caisson is assumed to rotate about a horizontal axis through its center line due to a horizontal mooring load.
		The effects of load-point application depth, caisson length to diameter ratio, soil strength characteristics, tip rotational resistance and soil unit weight effects are examined.

		The problem is that sometime before the concrete hardens, a vertical subsidence of 3 to 4 inches occurs in the middle of the caisson.
		The tremie-delivered concrete isn't vibrated, and it settles as the mass of concrete above it forces air from the concrete in the lower portion of the caisson.

	Fargo: A City Built on "Stilts"
		In part, then, Fargo is a city built on "stilts." Heavier structures are supported by concrete piers (caissons) or steel pilings that transmit the weight of the structure down to depths of 105 to 130 feet.
		Even the skywalks in downtown Fargo are supported by caissons, so as to assure that their weight won't cause them to drift in the weak clays underneath.
		Using at the completion of the augering of the hole, the base of the hole (where it is within glacial drift) is "belled": a special auger is used to widen the base of the hole (and caisson), so as to establish a larger surface area onto which the caisson will be supported.
