[0002] The bow section is generally composed of left and right side near-pyramid type semi-solid segments and a middle deck segment, and the left and right side segment bottom plates and side plates are double-curved and complex. Because of the reserved installation position of the bow section for the retractable gangway, and the connection of the tail section with the adjacent section to form a loading empty cabin, the left and right parts of the section are only connected by a middle single-deck, and the inside is hollow, and the left and right side segments also have cabin distribution, and the overall strength is weak. According to the previous construction method, in order to control the section welding precision, the section is assembled and welded in the form of a mold, the deformation is constrained by the mold, and the shape is maintained by installing a reinforcing tool inside before the section is removed from the mold.
