ISHIDA MUNEHIRO / NAKAJIMA MASANARI / HISAZUMI KAZUMASA

To increase the rigidity of a joint while shortening the construction period at the site.SOLUTION: An underground structure 10 extends in the longitudinal direction and comprises a plurality of steel segments 31 arranged in the longitudinal direction and the circumferential direction of the underground structure 10, a steel skeleton 30 having an elongate joint for joining the steel segments 31 adjacent to each other in the longitudinal direction and a transverse joint for joining the steel segments 31 adjacent to each other in the circumferential direction, and a filling transmission material filled between the steel segments 31 adjacent in the longitudinal direction and fixing the same to the joint of at least one of the longitudinal joint and the transverse joint.SELECTED DRAWING: Figure 2

【課題】現場において工期を短縮しつつ、継手の剛性を高める。【解決手段】地下構造物１０は、長手方向に延びる地下構造物１０であって、長手方向、および地下構造物１０の周方向に配置された複数の鋼製セグメント３１と、長手方向に隣り合う鋼製セグメント３１同士を接合する長手継手と、周方向に隣り合う鋼製セグメント３１同士を接合する横断継手と、を有する鋼製躯体３０と、長手方向に隣り合う鋼製セグメント３１同士の間に充填され、長手継手および横断継手のうちの少なくとも一方の継手に固着することで同継手を固定する充填伝達材と、を備える。【選択図】図２
