CONSTITUTION:First lot of caisson 3 is built up on a base box 2 landed on a mound 1, and a crane device 6 is assembled through a base 8 and a post 9 on the caisson 3. Form panels 10 are carried in by the crane device 6 and assembled, and concrete is placed to build up the second lot of caisson. The base box 2, together with the caisson 3 and the crane device 6, is floated, towed to a place of deep sea, and sunk to float the caisson 3. The caisson 3 so floated is towed and settled on the second mound 11 to build up third and fourth lots of caisson through the crane device 6 and a concrete hose 12. |
