FIELD: construction. ^ SUBSTANCE: method includes mechanical displacement of soil particles so that the lower layer contains fractions with size particle below the rated value, and the upper layer - fractions with size particle higher than the rated value. The device for the method realisation includes a frame with a knife and a comb fixed on it and a vibration mechanism installed on the frame. The comb teeth are arranged as narrowing from the knife to the end of the form. ^ EFFECT: increased resistance to washing of gravel-pebble soils that form natural and artificial riverbeds, and reduced contamination of a waterway with suspended substances coming from the surface, when commissioning canals and doing adjustment works in the riverbeds. ^ 3 cl, 2 dwg |
