Hello, everyone.

This is Enta.

The other day, I was so close to drilling four 23-meter holes lol

I have to be present for the entire count, but I don't get there until a little before 10:00.

If there weren't such losses...

Just saying that won't get me anywhere, so I'll do my best!

Life is a constant learning experience, lol.

But that's beside the point.

I often measure drilling times on site.

That doesn't really mean much, but it does serve as a rough guide.

I often use a stopwatch to time myself, saying things like, “That one was tough, so it took me five minutes,” or

"That one was a little soft, so it took about 4 minutes."

Actually, you can't really count on that, lol.

 

The reason is that,

The operator is making adjustments in response to changes in soil conditions (which they can't see, but can sense through the machine's movements).

When you notice it’s gotten a little stiff, gradually increase the feed pressure. (Turn the dial little by little.)

Then, we monitor the impact pressure and feed pressure to adjust the feed rate.

I'll stop at the point where I've made the most progress.

Once it softens, you lower the feed pressure to prevent the tip from clogging.

 

So,Drilling time is not a critical factor because soil conditions vary.That's the point.

If you want to measure time accurately, you need to keep the feed pressure and the impact pressure constant.

Otherwise, there would be nothing to compare it to. (I do think it’s actually quite difficult to maintain consistency.)

However, the total time from the start of drilling to the completion of grouting and subsequent movement is only an estimate.

The question is, "How many hours does it take to make one?"

Let's say a task that usually takes two hours to complete took two and a half hours due to a problem.

However, since it can be completed in an hour and a half at some locations, the number of units that can be installed in a day ranges from 3 to—

That's how it goes.

This is merely a rough estimate and depends on the number of meters drilled.

This guideline is extremely important for process management.

The key to project management lies in how quickly you can get a handle on the situation at the job site.

Are you able to identify the general guidelines for on-site construction?

Furthermore, since this guideline will affect your future pay rate, it’s important to fully understand it.

 

See you later.
