DEVICE FOR CONCRETE SLOPE CONSOLIDATION STRUCTURE HEATING IN WINTER PERIOD Russian patent published in 2006 - IPC E02B1/00 E02B3/12 

FIELD: hydraulic structures, particularly to perform concrete works in winter period.

SUBSTANCE: device comprises concrete heaters and heat insulation means. The heaters have pipe system including parallel perforated pipes laid on concrete mix of dam slope. The perforated pipes are connected to steam-boiler by common channel and are covered with polyethylene film or other insulation means from above. Distance between pipe perforation orifices and perforation orifice dimensions increase in direction from steam inlet point.
