下が図られる。(Effects of the Invention) In the present invention, the iron box is constructed in an assembled manner by fixing the opposing ends of a pair of left and right iron box component parts, and can sufficiently withstand the load in each direction of the train, and can be laid inside. Since the weight including the entire ballast track is sufficiently large, the height of the iron box on which the ballast track is laid can be reduced, and it can be used for a short time even in tunnels currently in operation and with narrow cross sections. A vertical elastic support is installed between the steel box and the bottom of the 1-basin road structure, and an elastic support in the rail direction and an elastic support in the direction perpendicular to the rail are installed between the side wall of the bottom of the R road structure. By interposing the steel box, the iron box is elastically supported in the vertical direction, the rail direction, and the direction perpendicular to the rail, thereby reducing the vibration of the obstacle structure.
