Along with the high-speed development of national economy, the speed, the load capacity and the like of a train are improved year by year, the number of the past trains is increased year by year, and the contradiction between the bearing capacity and the increase of the transportation capacity of the old equipment along the railway is increasingly prominent. When the tunnel passes through a water-bearing stratum and a rock fusion crack development section, water drops in the tunnel due to abundant underground water, when the temperature of air drops below 0 ℃ in winter, the water drops can be frozen, ice strips can be longer and longer until entering an insulation limit of a high-voltage contact net to cause a ground short circuit, so that a cable is burnt out, power supply is interrupted slightly, a net rack is scraped by a train, a support is pulled out, and derailment is caused. Therefore, deicing becomes a serious task in winter in the railway department. How to de-ice? The railway department also experiences a long and hard way of deicing, once a drainage method is found, namely, the drainage is carried out by drilling holes around the tunnel, but the hydrological runoff under geological conditions is too complex and the effect is very little. Later, diversion trenches are arranged on the wall of the tunnel, but the diversion trenches are often broken by ice arches. A cement leakage blocking method is also proposed, but after the hole is blocked, water is blown out from another place. 2011, someone applied for utility model patent once, direct contact's board ice-melt device that generates heat promptly, but only used less than two years on the tunnel wall, just dismantled totally, because its fate is the same with the guiding gutter, either burnt out by the ice hunch or the short circuit, perhaps do not switch on, in a word extremely unstable, extremely insecure reliable. In the period, manual ice making is not interrupted, a large amount of manpower, material resources and financial resources are consumed, and the method is original and low in efficiency.
