I don't usually have a chance to go to the "ventilator". "Take-chan" is also the first visit to a ventilation station in my life.

This ventilation station, built at Tsukiji 5-chome, Chuo-ku, has a structure consisting of three floors above ground and three floors below ground. There is a machine room on the second floor and an exhaust gas room on the third basement floor. The ventilation station has the role of collecting exhaust gas in the tunnel on the third basement floor, filtering it in a place called the exhaust air ventilator, creating clean air, and then discharging it to the ground.

It was written in the description.

It seems that this nameplate is the work of Yuriko Koike, Governor of Tokyo. By the way, the nameplate of "Tsukiji Ohashi" right next door is the work of former Governor Yoichi Masuzoe.

When I entered the tunnel, there was a description in some places like a museum. According to the report, "The height of the tunnel is 5.5m, about the same as a male giraffe. The width of the tunnel is 7m, just as much as a crocodile." 7m is the same as a crocodile, so I don't know much about the image. 。

Probably, as soon as you enter the tunnel from the Tsukiji side by car, a left curve toward Yotsuya / Tameike will appear. If you go to the ground at the exit of Shiodome / Daiichi Keihin, you can drive on the right lane and go to the ground around the left curve.

This is an air circuit breaker. According to the description, "It's a facility to prevent cars from entering in the event of an accident or disaster."

The reason for the error circuit breaker is that the wind pressure from the side is blown up. It's like "Koinobori".

I often see this in the tunnel. It seems to be called "Jet fan".

"In the event of a fire, it is a facility that transports smoke to the doorway." It seems to be a great machine that can generate a fiercely strong wind with a wind speed of 35m per second (126km / h).

Walking through tunnels is a lot of study.

There were descriptions like this in some places, and I felt worried that the participants would not get tired.

A return to the ground near Dentsu headquarters in Shiodome. It was an event that both children and adults could enjoy.

I can't wait for the opening.
