Description of the Related Art For example, in the case of a conventional caisson made of reinforced concrete or prestressed concrete, a partition is provided inside, and ballast water or the like is poured into a section defined by the partition so as to balance the whole. . In such caissons made of reinforced concrete or prestressed concrete, concrete panels are used as partition walls. However, since the thickness of the concrete panels is as large as 20 to 30 cm, the weight of the entire caisson becomes considerably heavy, and towing is performed. It has been a problem in time and in the ground improvement at the sunk position.

However, even in the case of this steel plate partition wall 3, a large number of stiffeners 4 are attached as shown in FIG. 9 in order to withstand ballast water pressure. Therefore, the partition wall 3 made of steel plate
In the case of (1), there is a problem that extra materials and man-hours are required since the stiffener 4 needs to be attached.

Since the shear stiffness is high and the stiffener 14 can be omitted, the weight can be reduced and the productivity can be improved. In addition, since it can be expanded and contracted by the corrugated shape, a predetermined amount of prestress can be introduced without exerting a reaction force in the prestress introduction direction and without causing buckling. This is the first box-shaped structure of the present invention. Reference numeral 15 in FIG. 1 denotes a PC steel wire that penetrates through a sheath tube 17 embedded in the outer wall 11b to introduce prestress.

After joining metal members 16 of the box-shaped structures to be connected to each other with, for example, bolts, a PC steel 15 wire is used. Through the sheath tube 17 to finally tension the PC steel wire 15. After the tension of the PC steel wire 15, the corrugated bulkheads 12 of the box-shaped structure to be connected are welded to each other. The welding of the corrugated partitions 12 is performed, for example, by butt welding as shown in FIG. 3B, welding in which the corrugated partitions 12 are overlapped as shown in FIG. 3C, or corrugation as shown in FIG. A flange 12a is attached to one of the butted end faces of the partition wall 12, and the flange 12a and the corrugated partition wall 12 are welded. Thus, the connection is completed.
