PURPOSE:To shorten a horizontal trunk and reduce its cost by forming a required number of wells at the contact area of a number of floating bodies that are to be adjacent to one another and sequentially joining the contact area of both floating bodies partially using these wells. CONSTITUTION:Wells 26 to 31 are formed at the contact areas of a number of floating bodies 2 that are adjacent to one another. Each of the floating bodies 2 is floated on the water level, pulled nearer, and is brought in contact with each other. When the contact areas are joined, a horizontal trunk 34 whose upper surface is opened and in which the sealing section is fit is brought in contact with the lower surface of each of the floating bodies 2 and a vertical trunk 43 with the same structure that is opened at the contact position of each of the floating bodies 2 is brought in contact with the inside of the wells 26 to 31. Then both trunks 34 and 43 are connected and fixed to each other. Mutually butting bottom plates and lateral bulkheads are welded after displacing water from both trunks. |
