Abstract

PURPOSE:To exactly prevent the upward effluence of a stabilizing grout by injecting a specific unit amount of a quick-setting grout from the upper injection port into the ground in the stabilizing treatment work of the ground by using a grout. CONSTITUTION:The liquids A and B of a two-component quick-setting grout are sent under pressure through inner tubes 2 and 3 into the first mixing portion 6 of the top device of an injection pipe P. The mixed first liquid G1 is then injected into the ground from the first injection port 7 in an unit amount of 1-6 liters/min, where the mixed grout G1 solidifies without cracks being developed. Then, liquids C and D as grouts suitable for the ground to be improved are sent under pressure through inner tubes 4 and 5 into the second mixing portion 8, and the mixed grout G2 is discharged from the second injection port 9.
