FIELD: pipeline laying technology. SUBSTANCE: according to method, bore-hole is made in ground bank between feeding and receiving basins according to design axis. After that, seated in bore-hole is steel casing. Internal diameter of steel casing is not less than external diameter of pipeline made of non-metallic material. Now pipeline is inserted into steel casing. After seating of steel casing through its entire length it is removed from bore-hole. Before removal of casing, pipeline is shaped as required to correspond to its working condition and this shape is maintained during removal of steel casing from bore-hole. EFFECT: increased operating reliability of pipeline with simultaneous affording possibility of laying pipelines in ground of practically any category of hardness. 4 cl, 3 dwg
