Abstract

L'objectif de la présente invention est de fournir un procédé d'amélioration du sol qui peut empêcher la persistance de morceaux de sol avec de grandes dimensions représentatives. Pour cela, dans le procédé d'amélioration du sol de la présente invention, des appareils d'injection (1, 10) injectent du fluide de coupe (par exemple, de l'eau à haute pression ou de l'air à haute pression, contenant parfois un matériau de solidification) pour effectuer la coupe, fournissent le matériau de solidification, et mélangent et agitent le sol coupé (G), le fluide, et le matériau de solidification pour produire un corps consolidé souterrain. Les appareils d'injection (1, 10) comprennent une pluralité de buses (N1, N2) positionnées dans la direction verticale avec des espaces entre elles. Lors de l'injection du fluide de coupe, les appareils d'injection injectent le fluide de coupe obliquement vers le bas (J1) à partir d'une buse supérieure (N1), et injectent le fluide de coupe obliquement vers le haut (J2) à partir d'une buse inférieure (N2).
