令和６年8月、台風第10号の影響による洪水を首都圏外郭放水路に取り込む様子を管理用のCCTVカメラで撮影した映像です。 ※排水後に調圧水槽を清掃する様子を追加しました（2024.9.12更新） 首都圏外郭放水路は倉松川、大落古利根川など中小河川の洪水を地下に取り込み、地底50ｍを貫く総延長6.3ｋｍのトンネルを通じて江戸川に流す、世界最大級の地下放水路です。平成14年に第３立坑までの施設が部分通水して以降、首都圏外郭放水路に水を取り込むのは今回で148回目となります。 江戸川河川事務所の公式HP https://www.ktr.mlit.go.jp/edogawa/in... 江戸川河川事務所の公式X https://x.com/mlit_edogawa This is a video taken by a CCTV camera in August 2024 of floodwaters caused by Typhoon No. 10 being taken into The Metropolitan Outer Area UnderGround Discharge Channel. *Added a video of cleaning the pressure adjusting tank after draining (Updated 2024.9.12) The Metropolitan Outer Area UnderGround Discharge Channel is one of the world's largest underground discharge channels, taking in floodwaters from small and medium-sized rivers such as the Kuramatsu River and the Ootoshi Furutone River underground and discharging them into the Edogawa River through a 6.3 km long tunnel that penetrates 50 meters underground. This is the 148th time that water has been taken into the The Metropolitan Outer Area UnderGround Discharge Channel since the facility up to the third shaft was partially opened in 2002.
