| 成果简介 | NOVELTY - Invention relates to the field of hydraulic engineering and can be used to restore water impermeability of a hydraulic structure in a developed cryolite zone to prevent bypass filtration in conditions of thawing of permafrost soils of the base. Method involves sequential pumping of 7% solution of polyvinyl alcohol, 0.3% solution of sodium tetraborate and pulp in the form of a mixture of water with products of kimberlite processing by interval injection under pressure less than pressure of hydraulic fracturing of soil material, through injection wells – injectors. Injectors are drilled along the line crossing the filtration zone into the body and base of the hydraulic structure. USE - Hydraulic engineering. ADVANTAGE - Reduced filtration of process water through soil. 1 cl |
