PROBLEM TO BE SOLVED: To discourage a retaining wall fixed to a post from being damaged by a pressure of the water accumulating in the space between the posts, relating to a lightweight banking structure in which foam body blocks are stacked.SOLUTION: In a lightweight banking structure, a retaining wall 21 made from a concrete panel or the like is fitted to a front surface side of a post 14 including an H-steel provided upright by a plurality of numbers on a foundation 11, and foam body blocks 35 made from styrene foam are stacked on the foundation on a rear surface side of the post 14. A resin foam material 41 such as hard polyurethane foam material is injected and foamed between the posts 14 between the retaining wall 21 and the foam body block 35, so that a foam body made from hard polyurethane foam body material, semi-hard urethane foam material, or the like, is packed between the posts 14 between a retaining wall 21 and the foam body block 35. |
