幅に短縮することができる。FIG. 15 shows that a foam resin layer (25) is formed by laminating foam resin bodies (11) on the ground (23) while interconnecting them with sheets (22), and embankment (30) is performed. This shows an embankment structure for a track (32) in which railroad ties (31) are arranged in parallel on the upper surface and the track (32) is laid. In this case, since the foamed resin body (11), which is a lightweight material, was used, it was possible to prevent consolidation settlement of the embankment structure of the track (32), and since the foamed resin bodies (11) were interconnected, the structure was made more robust. It can be done. In addition, a foamed resin body (11) is made of a sheet (22) coated with adhesive on both sides.
) The construction period can be significantly shortened because the interconnections are made in a layer.
