Structure paving panel electric structure

The invention relates to a structural panel electric heating structure, in particular to a building surface and a paving panel electric heating structure with conductive concrete.

At high latitudes, climatic conditions often make roads prone to frost and snow, and cause serious impacts on pedestrians, vehicles and other users on the road, and even have security concerns. If the snow is serious, it is necessary to close the transportation modes such as roads and airports because of the safety considerations, which will bring a lot of impacts on passenger and freight transportation, and cause economic losses. Therefore, in order to keep roads open and safe, it is necessary to adopt immediate, rapid and effective frosting or snow removal in the cold and bad weather. It has always been a test of road traffic in high latitudes.

Conventional road de-icing methods include mechanical de-icing and chemical melting. Mechanical de-icing is nothing more than mechanical removal of snow through manual or de-icing equipment. This method is suitable for large-area cleaning operations, but when the temperature is low, the bonding force between the ice and the ice is large. The removal of snow is not complete. In addition, when the deicing equipment is in operation, the traffic must be interrupted to facilitate the smooth operation of the deicing operation. The chemical ice melting method melts snow by pouring a chemical agent to lower the freezing point of water. The most common type is mainly to melt the snow by pouring salt such as sodium chloride or calcium chloride. However, in the way of dumping salt, it will have an impact on the concrete structure and the environment, such as rusting the steel in the structure, causing damage to the erosion, and causing environmental pollution and many other negatives. problem.

It can be seen that the traditional way of road de-icing still has many shortcomings.
