FIELD: construction, water engineering.
SUBSTANCE: said utility invention relates to hydrotechnical construction, namely, to concrete works in the winter time. The device for heating concrete pavings in the winter time includes concrete heaters and thermal insulation covering the concrete on the surface. The heaters are designed as a system of parallel tubes laid on the concrete, on the dam slope, at a distance from one another. They are connected with one another continuously and cyclically for the circulation of liquid in them. The system input and output are connected to a heating boiler.
EFFECT: increased concrete quality and decreased energy consumption during works.
