Technical Field

[0001] The utility model relates to the technical field of tunnel operation safety, in particular to a highway water curtain early warning linkage system. Background Art

[0002] Tunnels, as special tubular structures, are often more disadvantageous than open roads in terms of rescue, evacuation and early warning of downstream vehicles. Therefore, when an emergency occurs in a tunnel, the highway tunnel management unit will immediately send tunnel traffic closure information through the information board and dispatch relevant personnel to set up roadblocks with rigid blocking devices such as cones and railings at the entrance.

[0003] However, in mountainous areas, it takes a certain amount of time for tunnel management units to rush to the tunnel entrance to set up roadblocks, which leads to a lag in vehicle prevention and control. This can easily lead to secondary accidents such as continuous collisions and fires after downstream vehicles enter the accident tunnel. At the same time, rigid roadblocks pose a great danger to drivers and passengers. Utility Model Content
