Daruma-otoshi Building Demolition


(YouTube link)

This is astonishing. Japanese company Kajima Corporation is using a building demolition method called daruma-otoshi in which they replace the support columns on the bottom floor with huge computer-controlled jacks. They dismantle the entire bottom floor, then lower the building floor-by-floor! Compared to blowing it up, this method saves time and space, pollutes the air less, and makes material recycling easier. And as much as we like to see old-fashioned implosions, you have to admit this is pretty cool to watch. Link -via the Presurfer

Peter, I think if you take all things into account: the time it takes to get permission to use explosives in a tightly controlled environment such as that (i.e. buildings nearby), the time it takes to plan, safety precautions, clean up afterwards (the dust cloud would probably be immense) and so forth I'm not at all amazed that this method is faster.

The actual tearing down phase may take longer than a quick kaboom, but there's so much more surrounding it, and I don't think you can beat this for safety anyway :)

I have been watching this since say, October... such a catchy tune. I always use it to cheer me up! <3

check out the user's other videos as well... equally cute and hilarious!

Well, of course it sticks in your head; it's insipid. That's why I can never understand people who use "catchy" as a positive term. Catchy is incredibly easy to write and annoying to anyone with any sense of musical taste.

I'm just amazed that anyone could find that rubbish catchy.

Maybe I'm just tired of the endless spew of cute animal videos accompanied by crappy songs. Maybe we need some real animal situations.

There's a bulldog squatting on my lawn.

It's a sack, full of kitty cats. And they meow, meow, meow, and they splash, splash, splash.

OK. That was undeniably cute. Now pass me the ear bleach. The "Demon DJ" in my head is going to get a lot of use out of that little tune...
