Hello, everyone.
This is Enta.
We've been using a new tool for our construction work since a few days ago.
It's a product called SoundScope.
Did you know?
This is a stethoscope used to listen to sounds transmitted through metal.
We are currently performing core drilling using the wireline method.
I listen for the sound it makes when I move that sampler (the part where you pack the core) to the tip.
If you extend it and simply place it against the casing, the internal sounds come through clearly.
According to the manufacturer, it was supposed to make a “click” sound when it was set, but,
It was hard to hear even when I put my ear to the casing, so I decided to buy one.
For now, we’re proceeding by starting the collection process after we hear the sound.
The reason we check is to ensure accurate installation.
Plus, I'm not used to this method yet, so I want to make sure I get it right, lol.
Once you get the hang of it, it’s not that hard to do, but I want to put my mind at ease ^^
This time, we drilled about 100 meters and collected samples.
At first, I wasn't able to get very good samples, but now I'm generally able to collect decent cores.
The soft parts melt a little, but it removes the hard parts thoroughly.
I think it's pretty good, since I can get about 80 percent of the points.
I'm hoping there'll be more jobs like this in the future, lol.
Please feel free to reach out to me ^^
Basically, I'll go anywhere!
Is the projected trajectory really accurate?
"What's the soil composition at the anchor's embedment point?" and so on
One of the advantages is that you can collect core samples in a relatively short amount of time.
This construction method is not common, but
It appears that this is being done as part of preliminary drilling in tunnels to identify fractured zones and the like.
See you later.
