Reinforced soil method using the temporal variation of flow characteristics and consolidation characteristics of its own hard-plastic-like gel

摘要

PROBLEM TO BE SOLVED: To provide a reinforced earth method of placing fill of self-hardening/plastic gel containing slug obtained form industrial wastes, as a main ingredient.;SOLUTION: The reinforced earth method is implemented by alternately and repeatedly carrying out a step of piling up wall surface blocks 2 on each other in multiple layers, a step of filling the self-hardening/plastic gel on a rear side of the wall surface blocks 2 as the fill 3, and a step of laying a plurality of fill reinforcing materials 4 on the rear side of the wall surface blocks 2. Each wall surface block is formed so as to have a self-standing shape. The height of the wall surface blocks 2 piled up in a single piling procedure is set to a value that can withstand earth pressure of an injection amount of the fill 3 in the course of a single injection procedure. Further the injection amount of the fill 3 in the single procedure is set to a value that is equal to the piled-up height of the wall surface blocks 2 in the course of the single piling procedure. Then the fill formed 3 of the self-hardening/plastic gel containing slug (material S), a calcium-based powdery curing expression material (material C), and water (material W) as effective ingredients, is injected, and a fill reinforcing material 4 is laid on the fill 3 after hardening the same in every procedure.;COPYRIGHT: (C)2007,JPO&INPIT
