The air shaft 65 is communicated with the cable channel 8 and the under-rail channel 32 through a ventilation pipeline pre-buried in the air shaft bottom plate. The fan 65 may be periodically activated to supply air into the cable duct 8 and the under-rail duct 32 during normal vehicle operation. One specific way is as follows: in two adjacent air shafts 6, the fan 65 in one air shaft 6 supplies air to the cable channel 8 and the under-rail channel 32, and the fan 65 in the other air shaft 6 exhausts air from the cable channel 8 and the under-rail channel 32, so that air forms orderly flow in the cable channel 8 and the under-rail channel 32, and a normal overhauling air environment in the cable channel 8 and a normal escape and rescue air environment in the under-rail channel 32 are provided.

When a fire breaks out in the transportation pipeline 2, the fan 65 can be started to supply air to the under-rail channel 32, so that passengers can keep breathing normally when entering the under-rail channel 32. Further, when the horizontally sliding containment door 9 is opened, the fumes in the transport pipe 2 enter the under-rail channel 32. The fan 65 in one air shaft 6 is adopted to supply air to the rail lower channel 32, the fans 65 in the adjacent air shafts 6 exhaust air from the rail lower channel 32 outwards to discharge smoke, and passengers can enter the air shafts to evacuate and escape against the flowing direction of the smoke.

In order to increase the efficiency of the utilization of the track 3, the track 3 may also comprise a switch structure.

As shown in fig. 3 and 5, equipment cable channels 8 are also provided in the transport pipe 2 and the station 4, where various equipment and cables can be arranged, such as: electrical wires, signal wires, etc.
