Abstract
A hinged floating box caisson structure includes a central caisson, a pair of lateral caissons and a pair of end ballasts, these elements are adapted, when in a transport position, to be folded on one another. A system for straightening the end ballasts and for unfolding the lateral caissons is arranged to produce simultaneously a 180-degree rotation of the lateral caissons and the straightening of the end ballasts. One actuator is provided for controlling these simultaneous movements.
