Stability enhancement stop water for injection liquid chemical composition of the soil and stability strengthening water stopping construction method using the same

摘要

PROBLEM TO BE SOLVED: To provide a grouting chemical composition for soil stabilizing, strengthening, and water stopping, which has sufficient strength which enables stopping a large amount of water leakage and sump water; does not generate white turbidness and does not foam too much when it comes in contact with water; and moreover is sufficiently low in viscosity so as not to impose much load on equipment at site; and to provide a stabilizing, strengthening, and water stopping method using the same.SOLUTION: Provided is a substantially water-free grouting chemical composition for soil stabilizing, strengthening, and water stopping, comprising (A) component containing a polyol and an amine compound and (B) component containing an isocyanate compound. The polyol contains a polyether polyol (a1) and the amine compound contains an amine compound (b1) having a primary or secondary amino group.
