Disaster Countermeasures

Municipal Subways carried out seismic reinforcement work on tunnels and viaducts after the Great Hanshin-Awaji Earthquake, and completed it by 2003.

Currently, we are implementing seismic reinforcement work on structures so that subway operations can be resumed as soon as possible even after an earthquake of the Great East Japan Earthquake.

Reinforcement by wrapping concrete pillars with iron plates.

Inundation at the station will hinder operation and station functions, and it is expected that restoration will take some time.Inundation countermeasures, such as installing an inundation prevention device at the entrance of the underground station where there is a risk of flooding, We are taking measures such as installing an inundation prevention device at the ventilation opening on the road surface.
