FIELD: civil engineering. SUBSTANCE: anchor spindles are driven into ground at a distance of 4-20 their diameter from one another then D.C.. is passed through spindles, and its direction is changed periodically every 0.25-6.0 h. Before placing spindles into ground, each of them is fitted with a pointed end subsequently treated with coating consisting of, wt.-%: cement, 30-5-; sodium silicate, 50-70. EFFECT: higher efficiency. 2 dwg
