Low-vacuum tunnel traffic system and evacuation structure for low-vacuum tunnel

The invention relates to the technical field of low-vacuum tunnel traffic, in particular to a low-vacuum tunnel traffic system and an evacuation structure for a low-vacuum tunnel. A rescue tunnel of the evacuation structure and the low-vacuum tunnel are arranged in parallel, and the interior of the rescue tunnel is in a normal-pressure environment; a plurality of cross passages are arranged between the low-vacuum tunnel and the rescue tunnel, and the cross passages are used for communicating the low-vacuum tunnel with the rescue tunnel; one telescopic suspended corridor is fixedly arranged onthe side, facing the low-vacuum tunnel, in each cross passage, the outer circumferential surfaces of the ends, facing the rescue tunnel, of the telescopic suspended corridors are connected with the inner circumferential surfaces of the cross passages in a sealed mode, and the other ends of the telescopic suspended corridors can stretch along the extension directions of the cross passages; and fireproof air-tight doors are
