Description

technical field [0001] The invention belongs to the field of first-aid equipment for flood control at tunnel entrances, in particular to first-aid equipment for flood control at tunnel entrances. Background technique [0002] Although the tunnel entrance is generally equipped with waterproof facilities, when there is heavy rain, there is still a large amount of rainwater flowing down from the top of the mountain and pouring into the tunnel entrance, or the tunnel cave is located in a relatively low-lying area, resulting in water accumulation in the tunnel, vehicles stalling, and people being trapped. Being trapped in the tunnel brings inconvenience to people's travel, and sometimes the speed of accumulated water will cause the people in the tunnel to be unable to evacuate in time, which poses a greater threat to the safety of people's lives. [0003] The existing waterproof methods generally use sandbags to block or block through baffles at zero time, which is inconvenient t...

[0002] Although the tunnel entrance is generally equipped with waterproof facilities, when there is heavy rain, there is still a large amount of rainwater flowing down from the top of the mountain and pouring into the tunnel entrance, or the tunnel cave is located in a relatively low-lying area, resulting in water accumulation in the tunnel, vehicles stalling, and people being trapped. Trapped in the tunnel, it brings inconvenience to people's travel, and sometimes the speed of accumulated water will cause the people in the tunnel to be unable to evacuate in time, which poses a greater threat to the safety of people's lives

[0003] The existing waterproof methods generally use sandbags to block or block through baffles at zero time, which is inconvenient to use, or the rescuers use water pumps to pump water into the tunnel, but it takes time for the rescuers to rush to the tunnel, so there is an urgent need for an automatic detection method. Tunnel water level and rapid and efficient waterproofing of tunnel entrance flood control first aid equipment
