Zusammenfassung:	FIELD: building industry, particularly underground pipeline laying. SUBSTANCE: method involves digging out stepped trench having upper step formed as backfill trench of rectangular or trapezoid profile and lover step having rectangular profile; solidifying base for pipeline laying by means of plate having convex shell with radius equal to outer pipeline diameter; changing rectangular lower trench step profile to semicircular profile; lying pipeline into lower trench step; layered filling trench with soil from either pipeline sides; smoothing soil; solidifying the first soil layer by working plate having concave shall with radius equal to outer pipeline diameter; filling trench with the second and following layers and solidifying thereof; solidifying the last soil layer by means of flat plate, solidifying soil above trench at the height of not less than 0.3 m by means of flat plate or vibroroller. EFFECT: increased reliability of pipeline securing. 9 dwg
