Key equipment in this speedy pile-setting operation is the piston-driven swinghead which operates pneumatically, twisting the cassions through 40 ft. of silt and into the limestone bedrock about twice as fast as conventional hammering could sink them. A pile is then cast in place inside a permanent steel tube set in the caisson. Upon completion of the pile, the caisson is extracted and moved to a new pile location where the cycle is repeated. Only 6 caissons are required to install all the piles. The details of the setting up, concreting down, and pulling out operations are described.
