PROBLEM TO BE SOLVED : To provide an earth-pressure reducing construction method for a retaining wall having a constant retaining-wall back angle such as a masonry retaining wall, a concrete retaining wall or the like.
SOLUTION : A block-shaped foamed-resin molded form having inclined planes corresponding to the retaining-wall back angle and a ground stability gradient angle and having a specified shape is used. The molded form is carried out so that the inclined plane corresponding to the retaining-wall back angle of the molded form and the inclined plane corresponding to the ground stability gradient angle are arranged between the retaining wall and the natural ground so as to form a projecting-shaped wedge form or a trapezoidal shape in a lower section in parallel with the inclination of a retaining-wall back and the cut inclined plane of the natural ground respectively. |
