Rotary Drilling Machine To Break Stones, Can Use Auger?

Today, let's talk about rotary drilling tools: twist drill.

Speaking of auger, are not unfamiliar, not on the ground!

Do a few years of leasing, no construction experience, see a lot of sites, see auger, are playing soil.

To be honest, a recent special investigation has dispelled the erroneous view that auger can only hit dirt.

Yes, I'm sorry to say, I used to think that auger couldn't break stone.

In fact, the biggest reason is also: never seen.

The current construction machinery, Chinese is the best?

The biggest, the first, the best in the world.

How about basic engineering research and drilling tools?

Do the main engine does not work method research, do the boss does not recognize the full function of the drill.

He who knows nothing is fearless.

In fact, think about it should also know.

With the complexity of piling,

How can it be just the bailers and the tubs?

Vision, limited my thinking;

Confidence, and an accomplice.

However, why do you see less auger when you hit the rock?

Is the customary operation of construction technology,

Can't use it?

Or the drill bit quality of the drill manufacturers is not up to standard,

Not durable?

Is that rock auger drill bits have limited ground applicability,

Not a good deal?

It's the drill guy, unprofessional, doesn't know,

Marketing not in place?

It is the auger construction, there are great disadvantages,

A replacement product?

Existence is reasonable, which is worth thinking about.

Of course, can not be used blindly, auger also has advantages and disadvantages.

For this reason, I consulted the senior practitioner Korean workers, and learned that the auger was used to hit the stone until the cone appeared, and the use was less.

Auger has great damage to the machine, especially the drill pipe and the power head; Easy deviation hole; Easy to break drill bit, high noise when drilling dry holes.

Yeah, old and new. It's normal.

What is the future of auger?

Han Gong said that the auger penetration rate is fast, suitable for short piles that do not require perpendicularity.

Yeah, there's no universal pile driver, and there's no universal drill.

With the progress of process technology, the integration of combined drilling tools may be the advantage of open-rock auger.

Some drill tools are not commonly used, better understood.
