Hello, everyone.
This is Enta.
We’re getting calls from all over asking us to handle emergency repairs.
Since we’re operating according to the general contractor’s schedule, there are some things we can’t help, but we’d like to cooperate as much as possible.
In doing so, we are proposing ways to shorten the construction schedule.
It’s hard to say anything about this since explaining and negotiating those details is the general contractor’s job, but if they could just hand everything over to us early on, it would make things easier for us and keep things running smoothly lol.
We're all in this together, so let's do our best to make these changes!! lol
But that's beside the point.
The Significance of Drilling for Slime Collection
You know how sometimes you end up with slime when you're doing anchor work, right!?
I don't usually take on first-tier subcontracts, but I will if instructed to do so.
What does this tell us, anyway??
To be honest, I don't really know anything about it lol
If I had to say,I guess it's just a matter of color, huh?
1 m, 2 m, 3 m... up to 20 m, and
Even if I collect samples every meter, they’re already completely mixed together, and in fact, I can’t even tell which part the slime came from.
They're busily catching them with a net, aren't they?
For example, because I forgot to pick up the slime,Even if you cut down the mountain next to it to harvest it, no one would be able to tell, lol.
I might be able to tell the colors, at least
Boring Log—Core Photographswhile watching
On site, comments like, “Oh, this looks just like the actual data,” or “The color and hardness are similar,”
It would be fine if it were used properly, but it seems to have turned into some kind of nonsensical situation where, if an inspector asks, “Did you take a slime sample?” you just end up taking one.
What’s more, even if you’ve obtained the documents, the government office won’t accept them when you submit them.
"Just take care of it over there..."
So what's that then?? (Already trash)
The Drilling Slime is not a target for inspection.
I’ve never once been asked during a final inspection if I made sure to remove all the slime.
Has anyone ever been told that??
Besides, it’s not even subject to inspection, is it?
It doesn't affect the score, either.
The inspector has never even asked me about slimes!
You cannot make design changes after collecting a slime.
You cannot make changes—such as increasing the design length simply because the color of the anchorage section differs—based on comparing the collected slime samples with the bar chart.
Generally speaking, there is no need to change the design of the anchor length itself, as long as the borehole diameter remains the same.
Since the friction on the circumference changes when the drilling diameter changes, the drilling length also changes.
The Position of the Japanese Geotechnical Society
Design and Construction Standards for Ground Anchors and Explanatory Notes, p. 91
It says this.
The color of the slurry during drilling and the drilling speed (which indicates the hardness of the rock) are used as references for assessing the suitability of the ground.
And, Appendix Table 3-1
Design and Construction Standards for Ground Anchors and Explanatory Notes, p. 140
Please see the note at the very bottom.
Even under the same geological and weathering conditions, the color tones often differ.
What this means is,
That just goes to show that you can't rely on a slime's color.
So it's just for reference, I guess lol
And that just goes to show, “I still don’t get it, lol,” lol.
It’s also quite common for the color to gradually oxidize and change.
As a construction manager,
From an administrator's perspective, I think either option is fine.
If you want to collect it, go ahead; the same goes for the opposite.
If you can say with certainty, “I won’t take it!” then that’s fine.
There is no penalty for not collecting the sample.
So it's all on you, huh? lol
See you later.
