Then, connect the new submerged box to this trolley, drive the cart to the joint end of the existing submerged box, lower the submerged box, and join the joint ends of the existing submerged box and the new submerged box. Next, the trolley was returned to the original mounting point, another immersed box was connected again, and the immersed boxes were joined one after another to the joint end of the existing immersed box using the same procedure as above, and the structure was placed underwater. An immersed construction method characterized by construction.
