CAISON Meaning and Definition

  1. A "caisson" refers to a large watertight structure or enclosure used in underwater construction, particularly for creating a dry working environment below the water's surface. The word originates from the French term "caisson" meaning "box" or "chest." Caissons are commonly constructed from reinforced concrete and are often used in the building or repair of bridges, piers, or other structures submerged in water.

    In the construction process, a caisson is positioned at the desired location on the seabed or riverbed. It is then pumped with compressed air to displace water and maintain a dry space within. Workers can enter the caisson through an airlock system and carry out tasks such as excavation or placement of foundations for the structure being built. The pressurized air inside the caisson creates a stable environment and prevents groundwater or other fluids from infiltrating the workspace.

    Caissons are essential in engineering projects where traditional excavation methods would be challenging or unfeasible due to water presence. They help maintain structural integrity and facilitate construction activities in water bodies. Additionally, caissons can act as temporary or permanent support structures, providing stability during the construction process and ensuring the longevity of the overall structure.

    Overall, the term "caisson" refers to a specially designed, water-impermeable enclosure used in underwater construction to facilitate dry working conditions and foundation placement.

Etymology of CAISON

The word "Caison" has a French origin. It comes from the French word "caisson", which means "box" or "chest". In turn, "caisson" is derived from the Late Latin word "capsa", which also means "box" or "chest". The term "caisson" was initially used to refer to a wooden box or chest used for storing or transporting goods. Over time, its meaning expanded to include various other related concepts, such as a watertight structure or compartment, as well as a part of a ship or a sunken structure used in construction.
