In a conventional disaster prevention evacuation rescue project, particularly a repair-combined emergency rescue station in a tunnel, the evacuation requirement of people after a train on fire stops is met, and an independent people evacuation channel and a smoke evacuation channel are required to be arranged according to the principle of separating people from smoke, as shown in fig. 1 and 2. The personnel evacuation channel is connected with the evacuation flat guide and used for evacuating personnel outside the tunnel, and the smoke exhaust channel is connected with the smoke exhaust channel and used for exhausting fire smoke generated by the fire train, namely at least two auxiliary tunnels connected outside the tunnel need to be arranged on the tunnel body rescue station section. Due to the restrictions of terrain and geological conditions and environmental protection, the selection conditions and difficulties of the auxiliary tunnel with proper length and good entrance conditions are difficult to find on the key lines affecting the construction period of a newly built project, especially in the complicated and hard mountainous areas, so that the arrangement of the auxiliary tunnel at the rescue station is very necessary to be simplified.

⑤ constructing arch wall to form lining arch, arranging middle-buried rubber water stop belt around the arch to the construction joint;
⑥ constructing drainage cover plate ditches in the people evacuation channel.
The invention has the advantages that the upper and lower partition tunnel auxiliary tunnel structure is provided to replace the traditional auxiliary tunnel structure, on one hand, the principle of separating human and smoke in disaster prevention evacuation rescue is satisfied, so that the human evacuation and the smoke pumping are both in independent space, and the utilization rate of a single auxiliary tunnel during operation is improved; on the other hand, additional auxiliary tunnels are avoided, and the problem that the auxiliary tunnels are difficult to select addresses is effectively solved. Meanwhile, the scale of the auxiliary tunnel project is reduced, and the construction cost is reduced.
