LIGHTWEIGHT FILL METHOD AND LIGHTWEIGHT FILL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a lightweight fill method which prevents a support and a wall surface material from being deformed by a pressing force during foaming and a tensile force generated by contraction during cooling, and a lightweight fill structure which prevents the deformation etc. of the support and the wall surface material.;SOLUTION: The lightweight fill structure is constructed by using an assembly for fill, which comprises: a bedrock 3; the support 4 erected on the bedrock; the wall surface material 5 supported by the support; a panel 21 for a buffer layer, mounted on the slope side of the support; and a buffer panel 22 for a partition, arranged in such a manner as to be laid between the wall surface material and the panel for the buffer layer and separated from the support. The lightweight fill method comprises a step of a lightweight fill body forming step, a buffer layer forming step, and a support portion foam forming step. The support portion foam forming step is performed after the completion of the lightweight fill body forming step and the buffer layer forming step, so that the lightweight fill structure can be constructed.;COPYRIGHT: (C)2011,JPO&INPIT
