Caissons For Construction Work Under Water

Caissons For Construction Work Under Water

Caissons are large watertight structures that are used in underwater construction projects. They are typically made of concrete or steel and are designed to withstand the pressure of water while providing a dry working environment for construction workers. Caissons are used for a variety of construction projects, including bridge piers, tunnels, and offshore oil platforms. The construction of a caisson begins with the excavation of a large hole in the waterbed. The caisson is then lowered into the hole and the space between the caisson and the walls of the hole is filled with a mixture of sand and gravel, known as the caisson fill. This creates a stable foundation for the caisson and prevents it from shifting or sinking. Once the caisson is in place, workers enter the structure through an airlock and begin construction. The interior of the caisson is pressurized to keep water out and to allow workers to breathe comfortably. Construction materials and equipment are brought in through the airlock, and waste materials are removed in the same way. Caissons are an important tool in underwater construction because they allow workers to operate in a dry environment, which is safer and more efficient than working underwater. They also provide a stable foundation for construction projects, which is essential for the safety and longevity of the structure being built.
