caisson
This term is primarily used in specialized technical registers, specifically civil engineering and military history. In a construction context, it refers to a massive structural tool designed to isolate a workspace from water, often associated with the high-pressure environments of deep-sea foundations. It is distinct from a simple cofferdam in that a caisson is typically a prefabricated structure that is sunk into the ground.
In a military context, the word evokes an image of historical artillery warfare, referring to the heavy wagons used to carry ammunition. While the engineering sense remains current in modern infrastructure projects, the ammunition chest sense is largely archaic or restricted to historical accounts of 18th and 19th-century armies.
Meanings
A large, watertight chamber used for underwater construction work, such as building bridge piers, which is sunk into the ground and pumped dry to allow workers to operate in a dry environment.
Examples
The engineers lowered the steel caisson into the riverbed to begin the foundation work.
We need to pump the water out of the caisson before the crew can enter.
The bridge pier was constructed using a massive pneumatic caisson.
They used a concrete caisson to stabilize the quay wall.
The soldiers struggled to pull the heavy ammunition caisson through the mud.
Check the caisson for any damaged shells before we move out.
A horse-drawn caisson carried the artillery supplies across the field.
