<P>PROBLEM TO BE SOLVED: To form a target body in a desired shape even if large internal pressure is applied to an inner surface of a box body from a heavy material when the target body is formed by expanding a folding type box body and charging the heavy material such as sediment in the internal space. <P>SOLUTION: The folding type box body includes: a pair of side walls 6 and 6, which extend in one horizontal direction X and face each other in an orthogonal direction Y to the one direction X; partition walls 8 which are positioned in a space 7 between both the side walls 6 and 6, and extend in the orthogonal direction Y to partition the space 7 into a plurality section spaces 7a in the one direction X; and a first hinge 9 through which respective edges of the partition walls 8 in the orthogonal direction Y are pivoted on the respective side walls 6. Each of the partition walls 8 includes a plurality of partition wall elements 12 arrayed in the orthogonal direction Y and a second hinge 13 through which mutually opposite edges of both the partition wall elements 12 and 12 adjoining each other in the orthogonal direction Y are pivoted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
