Tips for Preventing Collapse During De-watering Boring Operations

Hello, everyone.

This is Enta.

In dewatering drilling operations, after drilling the borehole, you insert a strainer pipe and then pull out the outer casing, right?

At that point, it all falls together (the inserted strainer tube falls along with it), right?

 

What do you do in situations like that?

Drain Pipe

I think I introduced something like this a while back.

 

It's nice to say things like this, too.

But, to be honest, it doesn't really matter much considering the price—it just slips out, lol.

They'll both go down together.

Every time I remove the casing.

 

I'll teach you my trick, lol.

It's quite effective on PVC.

Since SGP pipes (gas pipes) are heavy, please use plenty of them!

You're probably thinking, "What?" right?

PVC Eptosealer

It looks something like this.

For PVC, just attach it halfway around in two or three places, and you're good to go.

 

As the saying goesEptsealerThat's it.

If you wrap this around it halfway, it won't fall off.

Simply put, it increases circumferential friction resistance!

It's fine to wrap it around once.

 

If you wrap it around too many sections, it will be a little harder to slide it on.

And if you put too much in, it gets hard to take out lol

Connect the PVC pipes, and apply the Eptosealer while they are in this position.

Most of them have an adhesive backing, so they'll stick firmly, but if there's grease or mud on them, please wipe it off.

Then just stick it somewhere convenient, and you're all set.

 

This is for when the SGP is active, and since weight is applied when the angle is 5 degrees or more,

If you increase the friction—for example, by applying Eptsealer tape in several places along the length—it will become much harder to pull out.

It does make the inside of the casing a little heavier, but it still slides in easily.

 

Maybe we don't need that anti-slip mechanism at the tip anymore? lol

If you want to keep costs down, this is the best trick!

 

See you later.
