RECONSTRUCTION OF GROUND BY SOLIDIFICATION OF DRAINAGE BODY

PURPOSE:To obtain the superior supporting force and strength by forming a solidified body by pouring chemical liquid into a drainage body installed under the ground and forming a composite ground which is integrally formed from the press-compacted soil on the periphery and the solidified body. CONSTITUTION:A drainage body which is installed under the ground and for which press compaction acceleration is completed is charged with the suspension liquid of the inorganic fine particle pouring material through the low pressure type permeation pouring system and the suspension liquid is solidified. The load applied on the solidified body is reduced, and the solidified body and the press-compacted soil on the periphery are formed integrally, and a composite ground is formed. Accordingly, in comparison with a prepared pile, the product having the markedly superior strength and durability can be obtained.
