NATURAL GROUND REINFORCING EARTH CONSTRUCTION METHOD AND NATURAL GROUND REINFORCED EARTH STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a natural ground reinforcing earth construction method and a natural ground reinforced earth structure for stabilizing a slope of the natural ground irrespective of a nature of the soil constituting the natural ground, geological formation, a shape of a sliding surface, etc.;SOLUTION: The natural ground reinforcing earth construction method comprises a drilling process for drilling a hole 4 in the ground 2, an insertion process for inserting a reinforcing material 10 and a water-permeable bag body 12 into the hole 4 in a state that at least one water-permeable bag body 12 is attached to the reinforcing material 10, a first grout material injection process for injecting the grout material 25 into the bag body 12 under pressure, a second grout material injection process for injecting the grout material 25 into the hole 4 after the grout material 25 in the bag body 12 is hardened, and a head part treatment process for settling a head part 11 of the reinforcing material 10 on a surface 3 of the ground 2 after the grout material 25 in the hole 4 is hardened. By injecting the gout material 25 into the bag body 12 under pressure, the bag body 12 is expanded and deformed to push and expand the hole 4 so that the adhesion force of the bag body 12 (the grout material 25) to the hole 4 is enhanced.;COPYRIGHT: (C)2006,JPO&NCIPI
