BLOCK FOR LIGHTWEIGHT RETAINING WALL, AND LIGHTWEIGHT RETAINING WALL STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a block for a lightweight retaining block, which is lightweight, and can suitably maintain a balance of the load of a retaining wall structure, and to provide the lightweight retaining wall.;SOLUTION: The lightweight retaining wall is manufactured by employing a foamed resin body as a body, and arranging offset load adjusting concrete on a rear side lower portion of the foamed resin body, and then the lightweight retaining wall structure is constructed by using the block. Herein the volume ratio of the foamed resin body and an offset load adjusting concrete portion is set to the range of 70:30 to 95:5, and provided that the block for the retaining wall is divided into four divided regions by a horizontal plane that includes the center of gravity of the foamed resin body and is almost level with a bottom surface and a top surface, and a vertical plane that includes the center of gravity of the foamed resin body, is perpendicular to the horizontal plane, and divides a front side and a rear side of the block for the retaining wall, 50% or more of the offset load adjusting concrete portion is included in the divided region including a rear surface and the bottom surface.;COPYRIGHT: (C)2009,JPO&INPIT
