Description

Background of the Invention Field of the Invention The present invention relates to a road snow melting system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road snowmobiling system and a method of installing the same, and more particularly, to a road snowmobiling system capable of removing heat when snow or ice is piled on a road in the winter season, and a method of installing the snowmemory system.

Generally, when snow or ice occurs on a road, it is physically removed by a snow removal vehicle or chemically removed by using calcium chloride or the like, thereby causing a safety accident due to snow slip on the road or icing on the road, and occurrence of traffic paralysis , And establishes traffic safety.

That is, in the past, in order to perform such snow removal work, the road maintenance person always waits for the weather deterioration or the cold weather to appropriately perform the snow removal work. In recent years, when the heating line is buried in the road to reduce such inconvenience, A snow melting system using an electric heating line was developed that supplies electricity to this heating line to easily melt and remove snow and ice.

However, since such a snow melting system consumes a large amount of electric energy during operation, the importance of energy saving is emphasized due to the exhaustion of fossil fuel energy and the suppression of carbon dioxide emission for environment friendliness. There is a problem.

In order to overcome such a problem, a snow melting system, in which a heat radiating pipe capable of circulating a coolant such as an antifreezing liquid is buried in a road, and snow and snow are melted on the road using relatively warm geothermal heat .

The snow melting system using such a heat pipe is a system that circulates the antifreeze inside the heat pipe and transmits the geothermal heat to the road when snowing or freezing occurs on the road.

However, in order to apply the snow melting system using such a heat pipe, it is necessary to place the heat pipe on the base packing layer at the time of road pavement and then to carry out the asphalt pavement so as to cover the heat pipe, , Which is by no means an easy task.

The reason is that a large dump truck that transports and supplies the asphalt mixture at the time of road pavement and the asphalt mixture supplied from the dump truck are automatically run while the asphalt mixture is laid down to a predetermined width and thickness and heat is applied to harden the asphalt mixture, Packaging equipment such as an asphalt finisher for finishing the packaging passes through the heat radiating pipe disposed on the base packing layer, and pressure and impact are applied to the heat radiating pipe, which severely damages the heat radiating pipe.

In particular, when a dump truck, over which tens of tons to twenty tones or more of load is concentrated on less than ten wheels, passes over the heat radiating pipe disposed on the base packaging layer, the heat pipe is largely distorted by the concentrated load, When the asphalt finisher equipped with the track caterpillar passes over the heat radiating pipe, the plate made of the steel plate forming the caterpillar strongly contacts with the surface of the heat radiating pipe, and the surface of the heat radiating pipe is greatly damaged by the impact.

When the heat pipe is severely damaged, it is necessary to remove the asphalt again in order to replace or repair the heat pipe. However, the same problem may occur in the process of laying the asphalt, and the construction cost may increase.
