The invention discloses a positioning datum line-based sectional construction method for a transverse bulkhead of an ultra-large container ship, which comprises: a transverse bulkhead sheet body stageof mounting components by taking a 14m longitudinal section line and a 2m contour line as positioning datum lines for a transverse bulkhead, and after the sheet bodies are finished, reflecting the positioning datum lines to an unstructured surface; a transverse bulkhead assembling stage of placing the sheet bodies in the step S1 on an assembly jig, assembling, and welding to form an assembly; a transverse bulkhead segmentation stage of, after the assembly in the step S2 is segmented, forming positioning datum lines including a center line, a 14 m longitudinal section line, a 2 m contour line,a 150 MK line and a top plate transverse center line which are applied to the total assembling stage in segments; a transverse bulkhead total assembling stage of checking and correcting the positioning datum lines of the subsequent process after segmented manufacturing is completed; and combining the plurality of the segments into a large block. The segmentation precision is effectively improved,and the dock period is shortened.

    本发明公开了基于定位基准线的超大型箱船的横舱壁分段建造方法,包括:横舱壁片体阶段:对横舱壁以14m纵剖线和2m等高线为定位基准线安装构件,片体完工后,把定位基准线反驳非结构面;横舱壁组立阶段:将步骤S1中片体放置到胎架上进行装配焊接,拼成组立;横舱壁分段阶段:将步骤S2中组立装配成分段后,在分段上开设应用于总组阶段的定位基准线:中心线、14m纵剖线、2m等高线、150MK线和顶板横向中心线;横舱壁总组阶段:分段制作完工后对后道工序的定位基准线进行检查、修正;将多个分段组合成大型总段。有效提高了分段精度,并缩短船坞周期。
