Description

Technical Field

[0001] The invention relates to a heating and drainage scheme suitable for tunnel ice melting technology, and in particular to a drainage type heating plate suitable for tunnel ice melting. Background Art

[0002] When a tunnel passes through an aquifer, an area with developed karst fissures, or an area with abundant groundwater and shallow burial depth, tunnel leakage will occur. According to the location and size of the leakage, it can be divided into seepage, flow, leakage, and bubbling. When the temperature in the tunnel drops to around 0℃ in winter, ice often forms in the leaking area. Some of the leaks are sealed after freezing, and the ice continues to develop, invading the limit and affecting driving. Severe cases will cause the contact network to be electrified, ice will spread over the rails, damage the rails and accessories, and the sidewalls will invade the limit, causing serious harm to driving safety. In order to eliminate the formation of icicles at the seepage points in the tunnel and ensure the safety of railway power supply, a heating and drainage scheme suitable for tunnel ice melting technology is studied, which is specially used for deicing in tunnels. It can prevent ice from forming at the seepage points just above the contact network feeder and the load-bearing cable, and drain the melted water. Summary of the invention

The drainage plate guides the water after the ice melts to one side, and is installed on the tunnel wall through the drainage type heating plate installation hole to radiate heat to the tunnel cement wall surface. The radiation heating plate is provided with a guide hole, and the drainage plate is installed under the radiation heating plate. The water after the ice melts is guided to one side and discharged in the required direction to prevent the water from being transferred to the traction line or the rail to cause secondary disasters.
