Hello, everyone.

This is Enta.

The other day, I was compiling a list of Vietnamese workers.

There are too many names, so I can't tell which is which.

Names are tough, aren't they?

It seems that even in Japan, people with so-called “flashy names” are having a hard time, and we’ve reached a point where those whose daily lives are affected by them are even going so far as to change their names.

Language changes so dramatically—it really is, quite simply, difficult.

But that's beside the point.

Have you ever done static crushing?

It's actually pretty tough. (Or should I just say it's a hassle?)

 

That said, I’ve only done it a few times myself, but it’s easy to do.

Drill a hole in the rock with a rock drill → Pour in the prepared blasting agent → Plug the hole with a sponge. (This is optional.)

Finally, cover the top with a protective sheet to prevent anything from falling out.

That's it.

If you use the fast-acting type, it will break down in about an hour.

For that reason,During that time, be careful not to go under there under any circumstances.Please do so.

The slower ones can take about three hours, so you never know when they'll crack. (Sometimes, surprisingly, they don't crack at all.)

For safety reasons, we recommend setting up the static blasting charges around 11:00 a.m. and then taking your lunch break.

Naturally, the lower area is off-limits.

When climbing a mountain, please climb from both the left and right sides.

 

Here's a tip: If the material seems hard, reduce the drilling pitch.

And let's order a little extra material and pour a little more than usual.

If you skimp on this and it breaks, you'll end up having to do it all over again.

Surprisingly, if you skimp on this, it can actually end up breaking lol

If you can't do your job without breaking them, don't hold back—hit them hard and break them quickly.

When you factor in the material delivery period, leased equipment, and labor costs, the material costs end up being lower.

In practice, the process involves breaking the surface with a crushing agent and then inserting a crowbar into the crack to pry it open.

 

The cost estimate is approximate, but for medium-hard rock, it’s around 50,000 yen per cubic meter.

It depends on the specifications, but I think you should expect to pay roughly between 50,000 and 80,000.

Of these, labor accounts for about 60%, materials for 30%, and machinery for 10%.

This is strictly based on the design price.

Please refer to the cost estimate documents for details.

 

See you later.
