CAISSON INSTALLATION METHOD AND DEVICE

PROBLEM TO BE SOLVED: To solve problems in a conventional caisson installation method involving danger with inferior human workability because a person works on board a caisson at a destination. SOLUTION: The caisson installation method and device are provided on the caisson to be installed, with drainage and lubricating water pumps, a drawing winch, a water sensor in the caisson, a GPS mobile station, and a data transmission device and a radio transmission device for sending operation status signals of the drainage/lubricating water pump and drawing winch and data on the water level sensor and GPS mobile station to a mother ship and receiving start/stop signals of the drainage/lubricating water pump and drawing winch from the mother ship. A base station at a remote place is provided with a GPS base station, a correction information transmitter for sending correction information from the GPS base station to the GPS mobile station provided on the caisson, and a correction information receiver. Water in the caisson to be installed is drained by remote operation to float the caisson to be installed, and the caisson is towed to the destination and filled with water by remote operation. The caisson is then installed in a desired position by water filling operation and winch operation corresponding to information on the inclination and position of the caisson.
