Inter-district tunnels are relatively closed spaces, connected to the station at both ends of the tunnel, with a general length of 1200m and various pipelines set up on both sides of the tunnel side walls. Due to the constraints of the tunnel section design limits, the train body basically occupies the entire tunnel cavity, in an emergency, it is very unfavorable for the evacuation and rescue of passengers and staff, there are emergency evacuation safety risks.
