Description

Technical Field

[0001] The utility model relates to the technical field of tunnel antifreeze electric heating tapes, in particular to an antifreeze electric heating tape for tunnels. Background Art

[0002] Electric heating cables are constructed from a conductive polymer, two parallel metal conductors, and an insulating sheath. Their characteristic is the conductive polymer's high positive temperature coefficient. When connected in parallel, they automatically adjust their output power and limit the heating temperature as the temperature of the heated system changes. They can be shortened or extended within a certain range, and they can be crossed and overlapped multiple times without the risk of hot spots or burns.

[0003] In tunnels in cold regions, concrete structures can be subject to freeze-thaw cycles, leading to cracks and damage. Heating cables can be embedded in the concrete structure to provide an additional heat source. This uniform heating reduces the amount of moisture that freezes within the concrete, reducing the risk of freeze-thaw damage and extending the life of the tunnel structure.

[0004] Tunnel concrete in the existing technology requires the use of electric heating tape to increase the concrete on the tunnel side walls to prevent cracks caused by freezing. However, the traditional electric heating tape has a high pressure inside the concrete and is easily damaged, affecting the use effect. Utility Model Content
