Abstract: In the light of the characteristics of loose and fragile and large deformation in quick-sand strata, pressure injection with composite chemical solidified liquid was used to reinforce quick-sand strata fleetly. A composite chemical solidified liquid was prepared by vinyl epoxy resin and catalyst, and the characteristics, mechanical property of consolidation and solidification effect were investigated. The obtained results indicate that the composite chemical solidified liquid possessed lower viscosity, better injection, corrosion resistant and better fire resistance. The caking property between the new grouting material and fine sand is good, the non-deformability is better and the strength of solidification rock mass is strong. The engineering application has proved the validation of the new chemical grouting material.
