FIELD: construction engineering; erection of pipe lines on slope of mountainous terrain. SUBSTANCE: pipe is transported by rail track laid in bottom of trench, joints of pipes are insulated by thermally shrinkable couplings and are protected by envelopes; part of pipe line thus prepared is placed on supports made from soil sacks, after which rail track is dismantled, percolation strips are fitted and trench is filled with ground soil. EFFECT: enhanced reliability.
