This time, let's take a look at the situation at the subway station that was heavily damaged by heavy rains in Seoul last week.

There were several places that were submerged and closed due to the pouring water, but when we investigated, it was confirmed that there were devices that could prevent rainwater from entering the station, but they were not used properly and the damage was great.

On the night of the 8th, Isu Station on Seoul Subway Line 7.



The water fell like a waterfall, and the ceiling suddenly collapsed, and the inside of the station was filled with muddy water in an instant.



As a result of SBS coverage, it was confirmed that there were devices that could prevent such flood damage at the time, but they were not used in time.



At Exit 9 of the subway station, where the most rainwater flowed in due to the low ground, there was a water gate that completely blocked the inside and outside, and a water plate about 30cm in height was located at all entrances and exits.



However, these devices were installed only after water had already entered the station.



There is no manual in case of flooding, so we missed the golden time by installing only at the judgment of the on-site staff.



[Seoul Transportation Corporation official: It's a bit unusual to get water like this here, so I'll work on drainage here and install the shroud.

You are making your own judgment in this way.]



The damage that has grown out of control has not yet been repaired.



Exit 9 of Isu Station.



This escalator is broken and not working, and about half of this entrance is closed with a steel gate like this.



Dongjak Station, which was heavily damaged by flooding, became a problem because the station entrance and exit management was different.



Exit 6, which received the most rainwater, is managed by Dongjak-gu Office, not the subway operator.



The operator asked the ward office to remove the locked water plate and install it, but the ward office staff arrived at the site an hour later.



There is no Chasu Gate at Dongjak Station.



This is because, according to the urban railroad construction rules, flood protection facilities are optional and not compulsory.



With this flood damage as an opportunity, it is pointed out that it is necessary to prepare the minimum necessary equipment and manuals to protect subway stations that are vulnerable to heavy rain.



[Park Chang-geun/Professor of Civil Engineering, Catholic Kwandong University: When the torrential rain comes, you can install it in advance.

There should be a manual, of course, but since there is no manual, measures have to be taken.]
