SCRAPED-UP SNOW PILE MELTING DEVICE

PROBLEM TO BE SOLVED: To previously prevent a vehicle accident and an accident resulting in injury or death, to secure a road width or a parking zone to eliminate a trafic jam, or to secure a parking space by successively melting the scraped-up snow pile formed on the shoulder of a road and on a site. SOLUTION: In a scraped-up snow pile melting device, a hot-water feeding pipe 11 is arranged inside a drainage ditch 4 that has been embedded in the roadbed. At that time, a large number of injection nozzles 15 are upwardly arranged at intervals perpenduclar to the axial direction in the feed branch pipes 13 constituting the hot-water feeding pipe 11. Then, a part of melted snow drainage water taken in from the drainage ditch 4 is heated to a temperature of, for instance, approximately 30deg. by means of a hot-water generator 16, and the produced hot water is jetted toward the scraped-up snow pile through the injection nozzles 15 by means of a hot-water injection pump 25. The temperature of the jetting hot water and the temperature of melted snow drainage water are detected by temperature sensors 29, 30, and a control board 31 carries out automatic control for stopping the injection of hot water when a prescribed temperature difference is converged.
