The position of the mold 4 can be determined with high accuracy after the positioning is performed with relatively rough accuracy. When a cant is further required, the movable beam 12 can be tilted according to the required cant as shown in FIG. 2, and then the formwork 4 can be accurately tilted by the jack 14 to the required cant angle. Therefore, it is possible to construct the side wall 5 at an accurate position and with an accurate shape even in a track portion having a cant.

Therefore, it is possible to construct the side wall 5 with high accuracy. Moreover, since the formwork 4 is moved together with the gate form support frame 11 while being assembled, it is not necessary to assemble the formwork for each concrete placing, the movement and the formwork assembly are simplified, and the construction time of the side wall 5 can be shortened. become. Preferably, a gate type support frame
