Determining how to strikingly reduce the accident rate on roads, ensure traffic flow and safety in the icy weather, and improve the capacity and efficiency of transportation in snow weather has become a tough issue nowadays. A new method was presented in which thermal water-jet cutting was combined with mechanical-milling deicing technology, basing on current different deicing methods. Then the structure and working principle of this device were introduced, together with the practicality design. The experimental results indicate that this device can perform well in deicing work, and satisfy the design requirements.
