The Mystery of the Floating Rock (Shore Protection Work) | The Wonders of Structure

Hello, everyone.

This is Enta.

Since this was a construction method I saw for the first time at a NEXCO job site, I’d like to introduce it.

Shore Protection Work

This is the slope of the revetment.

A net with a mesh size of about 4.0 mm has been stretched across the entire mountain.

There's a rock stuck there.

When I first saw it, it seemed really strange, and I wondered, “How do they do that?”

It doesn't even look like there's any mortar or anything underneath.

It's really strange, isn't it!!?

 

And when I took a closer look...Shore Protection Work: Rocks

They drilled a hole in the rock, inserted a bolt, attached a metal bracket, and hooked it onto the net!

But it must take a ton of work, lol.

Each one was caught on the metal fastener.

 

The surface has been smoothed out to a certain extent, and there are few uneven spots.

I bet it was a lot of work to install this, lol.

I figured they'd point out even if just one was sticking out.

 

It must have been a very labor-intensive project, but the finished result looked great—it was the kind of work that really made me think, “Ah, I see!”

Naturally, the fasteners are secured from upstream to downstream, so it doesn't look like they'll come loose.

 

I wondered what this construction method was called, so I looked it up, but I couldn't find anything.

I couldn't find it online either.

It's surprising that there are actually construction methods out there that you can't find online, lol. (Manufacturers, get on the internet already! lol)

It would be a waste to go to the trouble of featuring something only for people not to watch it.

 

Still, this kind of unusual construction method is really interesting.

It will serve as a source of knowledge that builds your confidence.

It really strikes me—I really do love slopes!

 

See you later.

    I was really curious about this. So I looked it up, and I think this is probably it. It looks like it took a lot of time and effort, lol.
