Efficiency Analysis on the Synthetically De-Icing Technology Combining Thermal Water-Jet Cutting with Mechanical Milling

Abstract

Transportation always plays a significant role in national economy, of which roads and bridges are the most important facilities. The conditions of the road surface have an overwhelming influence on the traffic flow and road safety, especially in winter and the regions with frequent snowfall, thus closely affected the development of the urbanization and economic prosperity. In view of this, this article has analyzed the characteristics of the existed de-icing technologies, coming up with a new synthetically de-icing method which consists of thermal water-jet cutting with mechanical milling technology. These two kinds of de-icing methods are combined as a set of multi-functional system, in which the thermal water-jet cuts the ice layer into separated sections, and the mechanical milling unit then easily removes the remaining sections out of the road. To obtain the prime influential factors in this new de-icing device, repeated indoor experiments were conducted, which provides some theoretical references to further advance the de-icing efficiency and make structural optimization.
