PROBLEM TO BE SOLVED: To extend its construction extension, when constructing an underground structure by crossing under a road and a roadway by using a pipe roof.;SOLUTION: When constructing the underground structure (a crossing part tunnel 3) by crossing under the road and the roadway, the pipe roof 4 is formed by burying a pipe 5 in parallel in the ground G so as to cross under these, and a foundation 7 supported by the ground G is arranged in a position opposed by sandwiching this pipe roof 4. A support member (a main girder 8) is extended to this opposed foundation 7 so as to straddle an upper part of the ground G1 on the pipe roof 4, and a suspending member 9 is arranged downward from this support member. While suspending and supporting the pipe roof 4 at a predetermined interval in its shaft direction via the suspending member 9, after excavating the ground G under the pipe roof 4, the underground structure is constructed.;COPYRIGHT: (C)2006,JPO&NCIPI
