With the rapid development of cities, the scale of expressways and urban roads is getting larger and larger, and the total length of roads is increasing. However, traffic congestion and aircraft downtime are becoming more and more frequent. Research and research have shown that good road conditions are the key to normal road conditions an important factor in operation.

In winter, especially on snowy days, however, snow and ice on the roadway reduce the friction between the tires and the road, making it difficult to maintain the direction of the car. Therefore, how to solve the problem of snow accumulation on the street, now I will present a safe and environmentally friendly method of snow melting, electric snow melting.

When electric heating technology is applied to road surfaces, the entire system consists of a heating system and a control system. When the system is installed, it usually needs to be designed according to the composite structure of the road surface and the performance of the heating cable: cut a groove of 2 cm (width) x 2 cm (depth) on the surface of the concrete pavement layer. and then lower the heating cable into the groove (the heating cable is very preheated). Leave excess length, To avoid excessive force on the cable when the road surface is deformed). And fix it in the groove with wire braces and cement nails, and then lay the temperature control cable in the same way. After laying the cable, an asphalt concrete layer is laid. The heating cable and temperature control cable are removed from the edge of the road surface and enter the cable slot through the side ditch of the road surface to connect to the control circuit to control the heater's remote control system. Cable.

After the installation and laying of the snow cable on the overpass is completed, the heating cable can increase the road surface temperature by 1-9.9 ° C to achieve the effect of melting ice and snow. To prevent the snow from melting too quickly after heating and snow water entering other parts of the road causing the road to freeze, the rate of snow melting can be controlled by adjusting the temperature so that the water does not flow into the river. In addition, we can build rainwater ditches or lay rainwater pipes on both sides of the road. Even if the water flows down, the snow water can drain directly into the rainwater ditches.

The TXLP series heating cable can be used not only for most common road materials such as asphalt, cement and floor tiles, but also for snowmelt roads, bridges, roadways, sidewalks, car parks, airport runways, outdoor steps and other outdoor activities. Objects Ice melting and ground heating, snow melting of gutlets, lawn heating, fire protection of tunnel pipelines, etc.
