METHOD FOR CONSTRUCTING FLUID SEALING INNER STRUCTURE ENCLOSED BY OUTER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a large-scaled inner structure enclosed by an outer structure by which assembly at the site can be quickened while coping with the limit of vertical property of a column and by which assembly prior to transportation to the site can be realized. SOLUTION: An inner structure part 1 is joined with a corresponding outer structure part 5 in each module so as to construct n sets of modules. The n sets of modules are joined with each other at the site so that they form an inner structure enclosed by an outer structure. This construction method is applied to a long air distilling column.
