てもよいし場所打ちコンクリートで形成してもよい。According to the method of the present invention, a track girder made of concrete and having alternately provided sleepers for the sleepers and recesses for the adjustment sleepers in the longitudinal direction is installed on each rail on the upper surface of the paved concrete. It is characterized by being integrally installed at a position and laying a rail on the convex portion, and can be applied to both the construction of a new track and the rebuilding of an existing track, and the implementation thereof. In this case, the track girder may use a ready-made product or may be formed of cast-in-place concrete.

A gap is formed between the track girder 1 and the paving concrete 6 when the rail surface is at a predetermined height, and the gap is adjusted when the level accuracy of the surface of the paving concrete 6 is poor.
