  • Consolidation Of Soil By Introduction Of Solidifying Substances Into Soil (AREA)

Abstract

PURPOSE: To form a columnar solidified portion having excellent strength by a method in which in a process where a stirring blade group is penetrated, while the peripheral portion of the soft ground is solidified, in advance and also in a process where the stirring blade group is drawn out, the inside portion of the soft ground is solidified.
CONSTITUTION: In a solidifying work in which a grout is mixed with soft surrounding ground by a stirring blade group, in a stirring blade group-penetrating process, a gront is supplied only to the peripheral portion of the soft ground stirred to beforehand slidify the peripheral portion, and then in a stirring blade group withdrawal process, the grout is supplied only to the inside portion of the stirred soft ground to solidify the inside portion. Or, in the reverse penetration process, the solidifying treatment is first applied to the inside portion of the soft ground, and then in the withdrawal process, the solidifying treatment is applied to the peripheral portion. In addition, a solidifying treatment is also applied to the cross-sectional area of the partially lapped portion between the inside of the peripheral portion and the outside of the inside portion so as to increase the strength of the treated portion.
