FIELD: construction.
SUBSTANCE: method comprises trenching, laying a section of pipe of diameter greater than that of the pipeline, passing the pipeline through the section of the pipe, sealing the clearance between the pipe section and pipeline, filling the pipe section through branch pipes with fluid of density higher than that of the agent to be pumped through the pipeline until the pipeline floats up, and filling the trench. The pipeline sections are interconnected with the compensators.
EFFECT: enhanced reliability of the pipeline.
