Segmented U-shaped construction method for chimney of large container ship

The invention relates to a U-shaped construction method for a chimney segment of a large container ship, which comprises the following steps of: determining a segment construction base plane according to the arrangement characteristics of outfitting pieces in the segment, sequentially installing an internal platform assembly, a stand column, a left enclosure bulkhead assembly and a right enclosure bulkhead assembly, and finally installing a top platform assembly to form a U-shaped structural frame, and carrying out layered preassembling on the outfitting pieces at the moment, and after preassembling is complete, the front bulkhead assembly is turned over and installed, and a complete chimney section is formed. According to the method, the problem that the chimney subsection outfitting piece is difficult to install is solved, the site construction difficulty is reduced, the completeness of outfitting is improved, and the construction period of the chimney subsection is shortened. The method is suitable for seg
