Therefore, some underground passages now have escalators or Ladders and other equipment for the disabled. And these equipments are in the open-air environment at exit, therefore, will be affected on its service life, and the underground passage entrance that escalator is installed is not convenient for directly installing rolling gate, therefore also is not convenient for closing the exit of underground passage. Contents of the invention [0003] The technical problem to be solved by the present invention ...

AI Technical Summary

Problems solved by technology

However, some underground passages may be built relatively deep due to consideration of their safety factors, which is very inconvenient for the elderly and disabled. Therefore, some underground passages now have escalators or escalators at the exit Ladders and other equipment for the disabled

And these devices are in the open-air environment at the exit, so their service life will be affected, and the entrance of the underground passage with escalators is not convenient for directly installing rolling gates, so it is not convenient to close the exit of the underground passage
