FIELD: hydraulic engineering, particularly water conveyance structures of hydroelectric power plants and hydroelectric pumped storage power plants.
SUBSTANCE: water conveyance structure comprises composite reinforced concrete pipeline located at prepared base and provided with enclosing structure with covering forming cavity above prepared base. Pipeline is located inside the cavity. The water conveyance structure is provided with air heating means to heat air inside the cavity in cold period up to temperature exceeding 0°C. In the case of composite reinforced concrete pipelines usage the pipelines are located one near another and the enclosing structure covering defines cavity for all pipelines receiving. The covering may be at least partly formed of translucent material.
EFFECT: increased control reliability and structure life, reduced maintenance costs.
