Abstract:
The purpose of the present invention is to provide: a road structure whereby installation accuracy can be ensured regardless of topography, and the construction period and costs can be controlled; a forming jig to be used in the construction of the road structure; and a construction method for the road structure. This road structure includes a steel pipe pile including a first steel pipe pile and a second steel pipe pile to be staked in the ground juxtaposed in a first direction in which a road extends and in a second direction that crosses the first direction; a steel pipe prop connected above the first steel pipe pile; an upper end joint steel pipe disposed on an upper end of the second steel pipe pile or the steel pipe prop; a girder member that connects two adjacent upper end joint steel pipes; and a road floor slab disposed on the upper end joint steel pipe and the girder member. In a case in which, of the first steel pipe pile, the second steel pipe pile, the steel pipe prop, and the upper end joint steel pipe, the members positioned below are called lower members, and the members joined above the lower members are called upper members, joining sections between the lower members and the upper members are joined by eccentric joint members capable of joining so that a center axis of the lower member and a center axis of the upper member are eccentric to each other.
