PURPOSE:To consolidate a stabilizing solution uniformly without extreme variability of strength, by blending a stabilizing solution which is impregnated in digging of channel hole and comprises bentonite as a main component with a consolidating agent of cement type, an expansion agent, etc., while stirring after completion of digging. CONSTITUTION:In underground wall construction works, after completion of digging a stabilizing solution which is impregnated in digging of channel hole and comprises bentonite as a main component is blended with a consolidating agent of cement type which has 3.0-3.2 specific density, 3,200-3,700 fineness and chemical components comprising 0.7-1.2 ig/loss, 0.2-0.9 inso, 19.0-24.0 SiO2, 4.7-8.0 Al2O3, 1.8-3.0 Fe2O2, 50.0-64.0 Gao, 1.6-1.8 MgO and 7.0-10.0 SO3, an expansion agent, or further a dispersant and/or a strength enhancer in such a way that prepared consolidated material has about 2-30kgf/cm<2> uniaxial compression strength and about 0.2-2kgf/cm<2> shear strength and stirred. |
