FIELD: machine building.
SUBSTANCE: method of pipeline routing on marshy land involves determination of boundaries of sections of mineral and peaty soils, underground routing in mineral soil and surface routing along the peat surface in banked ground at the marsh transition with fastening of pipeline at boundaries of sections adjacent to the marsh, when the pipeline profile is being made curved at transition from underground to surface section with minimum bending radii. Pipeline section arranged on the marsh in initial position is arranged linearly with alignment of its longitudinal axis with axis of sections adjacent to it in mineral soil, and curved transient pipeline sections are made so that they can be turned relative to axis of pipeline sections adjacent to them in mineral soil by means of sealed sleeve connections.
EFFECT: reduction of labour intensity during pipeline routing; improving operating reliability of pipeline.
