FIELD: construction engineering; underground laying of pipe lines. SUBSTANCE: proposed method includes securing screw anchors in soil of trench bottom at definite depth followed by injection of binder into soil at pressure of 0.2 to 1.5 Mpa through holes in lateral surface of anchor rods. Injection of binder is performed in wide range of pressures depending on physico- chemical properties of soils. Laying insulated pipe line and connecting it with anchor rods shall be performed after securing the anchors. EFFECT: enhanced reliability. 2 cl, 1 dwg
