A few days ago, Hubei melted ice for the Baisangguan Bridge in the Yunshi section of the G59 Hubei Expressway through the electric snow melting de-icing system, which is the first time that hubei jiaotong hubei northwest operation company has officially put it into use after the pilot construction of the system. The reporter saw at the scene that the electric heat melting snow de-icing system melted all the snow on the lane and the passing lane wheel track line, forming a sharp contrast with other road surfaces.
The "Electric Blanket" system is being deployed
"Snow in winter is a very beautiful natural landscape, but it is a big problem for vehicles driving on mountain highways; after the vehicles roll over the snow, it is easy to freeze and slip, and the snow melts the road ice, making driving more dangerous." Northwest Hubei Operating Company site maintenance administrator said. At present, all localities carry out road snow removal, anti-freeze and anti-skid emergency protection work, and generally use mechanical snow removal or spreading snow melting agents, but there are problems such as secondary icing, corrosion of the road surface and pollution of the environment.
In order to solve this problem, the company and Hubei University of Technology to carry out scientific research cooperation, according to the winter mountain bridges are more prone to snow and ice characteristics, specially selected the Yunshi Expressway Baisangguan Bridge as the test section, along the one-way lane and overtaking lane each lay about 60 meters of carbon fiber line, for the bridge deck road equipped with "electric blanket".
Snow falls on the wheel track line
According to Xing Jiaming, Engineering and Conservation Department of Northwest Hubei Operation Company, the core of this system is to rely on carbon fiber heating technology, by opening the system 2 hours in advance to preheat the bridge deck, so that the surface temperature of the bridge is maintained between 3 and 6 ° C, to achieve snow on the ground, to provide protection for the elimination of snow in winter, emergency management and vehicle travel safety.
