FIELD: hydraulic building, particularly to erect hydraulic structures and to built, reconstruct and repair pressure pipelines subjected to atmospheric actions.
SUBSTANCE: water pipeline comprises metal facing and reinforced concrete shell. Outer reinforced concrete shell surface is provided with roofing cover made of corrosion-resistant sheet material. Vent channels are formed between roofing cover and reinforced concrete shell. The vent channels may be provided with air intake devices having gates provided with automatic or manual drives. Removable inventory air dryers and air heaters may be arranged in vent channels.
EFFECT: increased service life and increased resistance of reinforced concrete shell subjected to repeatedly freezing and thawing due to provision of dry concrete condition during pipeline operation.
