FIELD: construction.
SUBSTANCE: installation of a pipe canal along the water reservoir bottom provides for completion of preparatory and main stages of its erection. At the first stage hydraulic insulation of the pipe canal is done. Then water impermeable elements - reservoirs - are placed on its surface. These reservoirs are filled with a hardened hydrophobic composition, for instance, a thermally oxidised mixture of soil and oil. Excavation is done in the bottom sediments of the trench. Helical piles are installed in it. The thermally oxidised mixture of soil and oil is injected into cavities of piles. Bottom sediments adjoining the piles are strengthened. The pipe canal towing, lowering, installation and fixation to piles is one, as well as trench filling with bottom sediments.
EFFECT: invention provides for durability and safety of pipe canal operation in northern regions.
