According to the method, a low-temperature stainless steel plate and a carbon steel structural part to be installed on the reverse side of the low-temperature stainless steel plate are manufactured into the inner bottom stainless steel segment in advance in an inner field, and then the complete inner bottom stainless steel segment is hoisted into the tank; and finally, a special turtle-type trolley is used for lightering to a pump well area, so that assembling and welding are completed, the problems of large welding difficulty, low welding efficiency and poor construction quality of bulk of a large number of structural parts and dissimilar metal in a narrow and closed space in the cabin are effectively solved, the working environment is greatly improved, and the mounting efficiency is improved.
本发明公开了一种用于在液货舱内驳运内底不锈钢片段的龟式小车,本方法通过将低温不锈钢板及待安装在其反面的碳钢结构件在内场预先制作形成一个内底不锈钢片段,再将完整的内底不锈钢片段吊装进舱,最后通过一个专用的龟式小车将其驳运至泵井区域,从而完成装配和焊接,有效避免舱内狭小密闭空间里散装大量结构零件、异种金属焊接难度大、焊接效率低、施工质量差的问题,大幅改善作业环境并提高安装效率。
