Research on the preset system for life rescue in tunnel door collapse
The construction of highway tunnels crosses mountains and valleys,and it is inevitable to pass through unfavorable geological bodies during the construction process.Due to insufficient judgment of unfavorable geological bodies or weak support structures,door collapse accidents occur when entering the tunnel entrance or during the main tunnel excavation process,posing a serious threat to the safety of construction workers.Under the existing tunnel evacuation and rescue measures,the safety needs of trapped personnel for escape and maintenance cannot be met;by analyzing accident rescue cases,a life rescue preset system has been developed.In the event of a tunnel door collapse,the system can smoothly establish a communication channel between the trapped space and the safe space,deliver supplies to them in a timely manner,and maintain the vital signs of the trapped person under the conditions of food,lighting,medicine,oxygen,and other materials;at the same time,contact the trapped personnel to obtain important information about their accidents and provide a basis for the rescue plan for tunnel collapse;winning valuable time for tunnel collapse rescue and improving the success rate of accident rescue.
