FIELD: construction. SUBSTANCE: artificial base 2 is placed on ice field 1 along the pipe line trajectory. The base is made up as a metallic grid or textile mat filled with a soil. Pipe line 3 is laid on the artificial base and secured to the base. Hole 7 is drilled in ice. Piles-stands 8 are lowered through the holes and secured to the bottom of a reservoir. Ice is cut along the pipe line on both side of it outwardly of piles-stands 8 and the part of the ice is lowered together with the pipe line to the reservoir bottom. EFFECT: enhanced reliability. 3 cl, 2 dwg
