LIGHT FILL DIRT STRUCTURE

摘要

PURPOSE: Light fill dirt structure is provided to prevent the plastic deformation of expanded plastic blocks used as fill dirt materials, thus achieving more stable and reinforced light fill dirt structure. CONSTITUTION: In the fill dirt structure constructed to wide a width of a slope to be charged with expanded plastic blocks between a front wall(3) and a rear inclined plane(2), the partial expanded plastic blocks(1b) used in at least one layer including the lowest portion of a charging layer has a compressive strength higher than a compressive strength of the partial expanded plastic blocks(1a) used thereon.
