In winter, the roads in most parts of our country will freeze due to natural weather such as snow and freezing rain, which will cause obvious harm to the smoothness of the road and safe driving. In severe cold areas and highways, highways, bridges and tunnel construction tunnels with high altitudes in Yunnan, because they are located in natural waters or above the Grand Canyon, the wind is relatively strong. When the cold weather comes, the road and bridge deck are very easy to freeze. High-speed ice-prone sections. In order to better ensure the smoothness and safety of the road surface, the road traffic unit needs to stimulate a lot of human resources and material resources to participate in the anti-icing protection in winter. Although the results are good, the cost is very high.
There are relatively few scientific studies on the melting of ice and snow on bridge deck structures in China, and the relevant scientific research results are not satisfactory. For example, the application of industrial salt, organic chemical snow-melting agents, etc., the harm caused by melting ice and snow to the natural environment is immeasurable. At the level of raw material composition, trying to reduce the ice degree of the bridge deck bitumen top layer or using ductile pavement to generate self-ice breaking road pavement structure cannot achieve satisfactory actual results in combination with the actual situation.
The heat transfer medium of the heating cable uses the power engineering as the power energy, the heating cable as the heater, converts the electromagnetic energy into heat, transfers the heat to the surface of the object according to the solid layer, and then develops according to the heat exchanger between the surface of the object and the wind and snow. The way to melt ice and snow. The heating cable heating system has the advantages of zero pollution, low operating cost, good heat resistance, and convenient operation. At this stage, heating cable heating equipment is mainly used in industrial buildings, outdoor equipment and road surfaces, and bridge deck snow removal.
