Claims

[Scope of utility model registration request]

At the joint of an immersed box constructed by sequentially connecting elements of a box-like body consisting of an inner shell and an outer shell underwater, a water stop plate is attached along the outer periphery of the outer shell at the joint end of the elements, and a water stop plate is attached to the inner periphery of the outer shell. A joint plate is attached to the side, a bolt is passed through the joint plate to fasten both elements, and a gasket is sandwiched between the water stop plates. At the same time, the inner shells are welded to each other, and both parts near the joint are connected. Alternatively, a joint structure for a submerged box characterized by incorporating a U-shaped member into either the inner shell or the outer shell to create an expandable structure.
