Hello, everyone.
This is Enta.
I'm starting on-site today!
Although it's still experimental, I plan to start posting videos on how to operate the rotary percussion machine at this site.
For now, I'm thinking of doing a live stream on Enta's Facebook page.
But since I messed up last time, I wonder how this will turn out? lol
Stay tuned lol

But that's beside the point.
There are some spots where vegetation is so thick that you can't pour concrete, right?
It would be great if it just cut through, but if it just won't cut no matter what, this is the solution!

Drill a hole using a core drill.
You're probably thinking, "You can't drill a hole with that, can you?" But you can! lol
This method is actually quite common in the Kanto region, isn't it?
It is frequently used, particularly in railway construction projects.
When installing rock bolts as part of seismic retrofitting work in Tokyo,
We are using a core drill to install rock bolts in a very confined space.
It's really hard work to dig by hand, but even so, you can still make progress little by little.
When working with 200V, you can use automatic feeders, which makes the job a little easier.

When the core begins to accumulate inside the core tube, remove it and let it drain out.
Then, while continuing to connect the sections, drill the hole to the specified length.
Enta Construction's track record is
3 inches (φ75) and 2,500 mm (100V core drill)
4 inches (φ100) at 3,000 mm (200V core drill)
It depends on the soil, but two a day would be perfect lol.
I think it would be fine if we could finish about one per day.
Since the drilling is mostly done manually, it takes time both to pull out the casing tube and to remove it.
And it uses quite a bit of water, too.
The construction equipment is compact, which is great because you can take it anywhere, but the actual construction work is extremely difficult.
That said, we’ve got the skills (or is it just sheer grit?) to handle any job, so we’ll just go ahead and do it anyway lol
If you're working in a really tight space, I'd recommend using a core drill.
However, please keep in mind that choosing the right soil type is the most important factor.
I remember having a really hard time with charts (rocks) back in the day lol
See you later.
