I went to the closure training of "Yodogawa Rikka" to shut down the bridge by dropping a huge iron door 24 meters long

Because disaster drills to close the bridge by moving the 24-meter long tapped iron door corresponding to the height of a 7 to 8-story building are to be done, go to the scene and make the whole story a picture and a movie I've included it.

The training site that covered this time is Osaka prefectureLanding gear at Yodogawa Bridge(Rikko).


Inside of this is a "tidal iron door" stored.



The intersection in front of the bridge looks like this.


There are a total of 4 lanes of roads on the bridge, and a considerable number of cars are in and around even at midnight, but at training time both people and cars will be closed.


A plate written as "Yoda Hajoshi".



There are the following embankments on both sides, but the part of the bridge is low, so it was created to prevent the river from overflowing from there, the "tide oil door" used in this training .



About two hours before closure began, the cars turning red light started gathering, and the site is packed with a fresh atmosphere.



People who seemed to be related people by taking a bus gathered.


A fire engine is also on standby.


People who wore uniforms written on the back with the Ministry of Land, Infrastructure and Transportation also appeared.


I approached the building where "tide prevention door" is stored and I am doing some work.


I saw the root part of the door.


Looking from afar, you can see the tip of "Anti-tide iron door" comes out.


A lot of elongated iron lumps are gradually getting up like a huge crane car boom (pole) often seen in construction sites.


Rotate this part 180 degrees to start, block the bridge structure.


The operation panel looks something like this.




It took about 3 minutes to slowly rise to about 45 degrees.


Compared with the person standing below, you can see the enormousness of the door.


When it becomes vertical it is like this.



Looking from the top of the bridge is as follows.


The state that the door rises slowly can be seen in the following movie.

When the door is almost vertical, the bridge is closed.


People who tried to pass through the bridge without knowledge of training were stopped by security guards.


The door comes down to the road.





Yodogawa Ohashi, closed closed.


Please check with the following movie for the whole story until you block the road parallel to the ground standing vertically.

Looking a bit further away, the strange sight that the road is suddenly blocked by a huge red lump.


Looking at the "tide oil door" in the near future.



The height of the door is 3 meters, and it is incredibly huge to see this moving as you see it at hand.



Looking from the top it looks like this.


When it is confirmed that the door normally got off, this time the work to rotate the door in the opposite direction and store it in the original place started.


A gap was visible under the door.


I will lift with Gungun.


After one minute we have created a space where one person can afford to pass.


It looks like this from the root side.


The state that the bridge lifts slowly can be seen in the following movie.

In 5 minutes, the door will come up to an angle of about 45 degrees, but the bridge is still closed for traffic.


People who watch the training.


The door slowly returns to its original location.


Almost complete storage.


When the road closure was lifted, the car started running as if nothing had been done as usual, and the training ended.


This training was carried out in the Yodogawa and Kanzaki rivers flowing in Osaka prefecture from midnight on July 7th 2012 to early in the morning of the 8th, and in addition to the Yodogawa Ohashi there are also a total of 17 tide iron doors such as the legendary bridge and the Kanzaki Ohashi bridge It was opening and closing.

In addition, training of similar contents is done every year, so there is no need to apply for observation, so you can watch the powerful working landscape just by going to the scene on the day, It is surely a fun that can be enjoyed when you visit the shrine.
