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

Abstract

PURPOSE: To produce an excessive gap water pressure in the ground and to reinforce the ground through the discharge of drain, by a method wherein a bag substance, whose diameter at its expansion time is larger than that of a bored hole, is placed upright in a hole bored in the ground to be amended, and the bag substnce is expanded by pouring.
CONSTITUTION: A pouring inner pipe 9 is inserted into a pouring outer pipe 6, and it is lowered to a lowermost position to pour into a bag substance. The pouring inner pipe 9 provides with a strainer part, and hackers 11 are mounted at the upper and lower parts. The outer pipe 9 can freely move at the inside of the pouring pipe 6, and thereby a pouring material can be poured by press into the desired bag substance. Resulting from the expansion of the bag substance to its original shape through pouring of the pouring material, the expanded bag substance consolidates and reinforces a spherical ground to generate a gap water. So generated gap water penetrates up to the upper part of the bag substance by a capillary phenomenon for the discharge.
