SOIL IMPROVEMENT METHOD BY SOLIDIFICATION PILE SITE PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide a soil improvement method by solidification pile site preparation which can develop high-strength solidification pile of stable quality without being influenced by original position soil in soil improvement work.;SOLUTION: A supply material is formed by mixing an aggregate such as gravel, crushed stones or the like with cement milk at a predetermined mixing ratio by a hopper 7 attached at the top of a casing pipe 4 by using a soil improvement construction machine provided with the casing pipe 4 which can be inserted in the ground. Then the supply material, which is formed by mixing the aggregate such as gravel, crushed stones or the like with cement milk at a predetermined mixing ratio, is charged from the hopper 7 into the casing pipe 4, and the casing pipe 4 is inserted in the ground. Then pull-out/back pouring is repeated while discharging the supply material from the inserted casing pipe 4, and the solidification pile is prepared in the ground. Thus, the soft ground can be improved into the stable ground by the soil improvement method by solidification pile site preparation.;COPYRIGHT: (C)2010,JPO&INPIT
