It is known that water drips on the top of partial tunnels of railways in northern China exist all the year round due to geological or construction reasons, and the water drips gradually form inverted icicles to be hung on the top of the tunnels in winter. When the icicles are enlarged and increased to a certain degree, the icicles are lapped with a lower power circuit to cause a circuit failure, or the icicles fall down to collide with the traveling vehicles, which causes great threats to the safety of railway, highway traveling vehicles in the tunnel and construction in the tunnel.

At present, the tunnel engineering maintenance and the electric power maintenance adopt a manual ice shaving mode to carry out deicing. The difficulty of manual deicing operation in the tunnel is very high, and the reason is as follows: firstly, the icing position is usually at the position 6 to 8 meters high at the top of the tunnel, and the manpower is often difficult to reach; secondly, the lower part of the icing part is generally a high-voltage power contact network, the artificial deicing operation is extremely dangerous, and random power failure on a continuously operating traffic line is impossible; thirdly, the operating environment in the tunnel is narrow, and the operating tools such as long rods with ladders and the like have potential safety hazards to the travelling crane and the pedestrians; fourthly, the density of the existing train is high, and the normal dispatching of the line is influenced by applying for a 'skylight point' (a railway dispatching department issues a command to a certain line, stops the operation of a locomotive and reserves a time section for overhauling and constructing) frequently in a long period, so that the normal dispatching is difficult to realize. Therefore, tunnel deicing becomes a very troublesome task in field maintenance work, and a simple method is expected to appear by field maintenance personnel.
