On Saturday, February 2020, 2, I visited the Kannana-Dori Avenue Underground Control Pond in Tokyo.After receiving an explanation about the facility outline, operation method, construction method adopted at the time of construction, etc., we went down the stairs to a depth of about 22 m underground and entered the inside of the regulating pond with an inner diameter of 40 m through the connecting pipe. ..In addition to the difficulty of planning and construction work, the tour is also pondering the importance of the role that this facility plays to prevent floods and the difficulty of maintenance, which is almost filled with river water during heavy rains. I was allowed to.

Unfortunately, the tour of the Sumida River bridges from the water bus was canceled due to the strong wind, but I think that the tour of the underground regulating pond alone was a rich tour.We would like to take this opportunity to thank the Tokyo Metropolitan Government Bureau of Construction and Tobu Toptours Co., Ltd. for organizing the tour.
