The invention relates to a construction method of a three-step type subsection, which comprises the following steps: dividing a three-step type section to be constructed into three sections, namely anupper platform section, a middle platform section and a lower platform section, respectively constructing and forming on a planar jig frame, and then reversely folding the middle platform section andthe lower platform section by taking the middle platform section as a base plane; and after welding is completed, two step segments are formed, the two step segments are turned over by 180 degrees and placed on the linear jig frame in a normal state, then the upper platform segment and the two step segments are folded in a normal state, overall welding is completed, and the three-step segment isobtained. By means of the construction method, the problems that the three-step type subsections are directly folded and formed on the plane jig frame in an inverted state, and the manufacturing height of the jig frame is too high are solved, fragmentation construction is adopted in the construction mode, the height of the jig frame is reduced, construction risks are greatly reduced, and the construction efficiency is improved.
本发明涉及一种三阶梯型分段建造方法,将待建造三阶梯型分段划分为上平台片段、中平台片段和下平台片段三个片段,分别在平面胎架上建造成型,然后先将中平台片段、下平台片段两种片段以中平台片段为基面反态合拢,焊接完工成两阶梯片段,两阶梯片段翻身180度正态搁置在线型胎架上,再将上平台片段与两阶梯片段正态合拢,整体焊接完工,得到三阶梯型分段。本发明的实施解决了三阶梯型分段直接在平面胎架上反态合拢成型,胎架制作高度过高的难题,在建造方式上采用片段化建造,降低胎架高度,大大降低了施工风险,提高了建造效率。
