Hello, everyone.

This is Enta.

I turned 47 today lol

When I was younger, I thought that at 47, I’d be a lot more of an old man.

But even though I look like an old guy, I don't seem to be that much of a geezer on the inside, lol.

But that's beside the point.

When inserting rebar using single-hole drilling methods, such as suspended drilling, there are times when the rebar just won’t go in, right?

Here's what to do in such situations.

That said, in places where the hole walls keep collapsing no matter how many times you drill, it’s just a drop in the bucket, lol.

 

First, if we think about why it won’t go in, the answer is obvious: the hole’s walls will collapse!

So why does it collapse? That’s right! It’s because the design is bad!! lol

But there's no point in saying that, and,Design isn't all-purpose.That's right.

 

The soil in the key areas had a solid N-value, so the mountain was supposed to be self-supporting. (According to the design)

However, contrary to expectations, there are many parts where that isn't the case, so you can't see into the mountains.

Since the construction team is the only one who can handle this, let's go ahead and do it.

 

First of all, how much of it doesn't fit? Does almost none of it fit, or just a part of it?

Is it just the beginning and the very end?

 

As a simple method, drill a hole once to the specified length and in the specified direction.

After that,Drill the hole while shifting it horizontally or vertically by about the width of one bit.I will.

Also, drilling slowly causes the hole to widen, making it even slightly easier to insert the object.

The most time-consuming part is forcing rebar into places where it doesn't fit.

Even if it takes a little longer, it’s easier on both your energy and your time to just drill a hole.

Just putting in the rebar is exhausting, lol.

It's more efficient to thoroughly clean the inside of the holes as well.

 

Even this might not fit in some cases!

So, what should we do about that? Is there any other option?

That’s something that makes you wonder, isn’t it?

 

Surprisingly, the moat is actually a great choice.

When water is injected, the surrounding rock is compacted by the water, making it easier for the borehole wall to remain self-supporting.

It's a good idea to mix some water with the air.

Just make sure to lubricate the machinery thoroughly with lock oil or grease at the end of the workday to prevent rust and other issues!

There's no problem as long as you're drilling with a swivel.

But since the area gets really messy, you'll need to clean it with a pressure washer lol

 

See you later.
