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.
Disclosure of Invention

③ binding the steel bars of the reinforced concrete vertical partition wall, pouring concrete in sections, and burying a buried rubber waterstop at the longitudinal construction joint;
④ constructing arch wall mold lining structure;
⑤ construction of drainage cover plate ditch and leveling layer in the evacuation channel, and drainage ditch in the smoke evacuation channel.
The invention has the advantages that the left and right partition tunnel auxiliary tunnel structure replaces the traditional auxiliary tunnel structure, on one hand, the principle of separating the human smoke in disaster prevention evacuation rescue is met, 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.
