GROUND FOUNDATION IMPROVEMENT METHOD
To provide a novel method that can easily and inexpensively improve ground foundations.MEANS FOR SOLVING THE PROBLEM: A method for improving ground foundations, which have in the depth direction hard layers and soft layers whose strongness is different, includes a process to form a first improved body in which the hard layers are improved with a triple-tube high-pressure injection stirring method which has three paths, namely a compressed air flow path, a cutting fluid flow path, and a solidifying material slurry flow path, and surrounds with compressed air at least either cutting jet flow or solidifying material slurry jet flow, and a process to form a second improved body in which the soft layers are improved with a single-tube high-pressure injection stirring method. The first improved body and the second improved body are continuously arranged along the depth direction. The triple-tube high-pressure injection stirring method and single-tube high-pressure injection stirring method are performed using the same triple-tube high-pressure injection stirring device. The single-tube high-pressure injection stirring method adjusts the air of the triple-tube high-pressure injection stirring device and controls the improved diameters of the first improved body and the second improved body.SELECTED DRAWING: None
【課題】廉価かつ簡易に地盤改良を行うことができる新規な方法を提供する。【解決方法】深さ方向において、強度の異なる硬質層及び軟質層を有する地盤の改良方法であって、前記硬質層を、圧縮エア流路、切削流体流路及び固化材スラリー流路の３つを有し、切削流体噴流及び固化材スラリー噴流の少なくとも一方を圧縮エアで囲繞してなる三重管高圧噴射攪拌工法で改良し、第１改良体を形成するステップと、前記軟質層を単管高圧噴射攪拌工法で改良し、第２改良体を形成するステップと、を含み、前記第１改良体及び前記第２改良体は深さ方向に沿って連続して並んでおり、前記三重管高圧噴射攪拌工法と、前記単管高圧噴射攪拌工法とは、同一の三重管高圧噴射攪拌装置を用いて行い、前記単管高圧噴射攪拌工法は、前記三重管高圧噴射攪拌装置のエアを調整して、前記第１改良体及び前記第２改良体の改良径をコントロールする。【選択図】なし
