Hello, everyone.
This is Enta.
Lately, on the Enta website, this "New Enta Slope Management School" blog, and just the other day, the LINE app.
There has been a significant increase in unauthorized login attempts to the site.
Before long, the whole site might get hacked and things could get pretty crazy. lol
If something weird happens, just assume the account's been hacked lol
That said, my junior was a victim of a LINE account hijacking last year.
That’s the thing where people used to buy WebMoney—which was all the rage for a while—at convenience stores, right?
A friend's LINE account was hacked, so I decided to mess around with the hacker.
But it’s a scary world, isn’t it? It seems to be getting worse every year, so this is no longer just someone else’s problem.
Please be careful with your own social media accounts and blogs as well.
If anything happens, call the police right away!
But that's beside the point.
How to Make a Packer: Part 2
But before that, I received a question regarding Part 1 of the previous post.
Q: For the "settling length," is the calculated value acceptable? What should we do in the case of compressed types?
This is a tough problem, isn't it?
Personally, I think that when using a packer,Isn't the all-packer design the correct anchor structure?I think so.
When using a packer, it is used in cases where cement slurry escapes or leaks.
Or use this option if you don't want grouting done in other areas.
I think that's the true spirit of a packer.
However, the question above raises the point: “Aren’t tension-type anchors and compression-type anchors different?”
For now, let's set aside the possibility that the grout might be leaking.
Please consider the structure of a ground anchor.
In the case of tension anchors, the load is concentrated at the boundary between the anchored section and the free length.
That means an enormous compressive force is applied to the cement paste in that area.
Let's say there's a packer there. The edge is cut off, right?
Don't you think an all-packer is the way to go, after all? lol
Even if it’s practically impossible, I think it’s best to have a packer that’s at least 1 meter longer than the embedment length, if possible.
This is purely a structural issue.
*The pink part in the image above is the packer.
I think there are pros and cons to this way of thinking.
Here's what I actually think about tension anchors.
However, in actual construction projects, packers are rarely included in the design specifications, and even when design changes are made, the funding allocated is often rather meager.
Since we don't have enough money to use all-packers—even with ingenuity and corporate efforts—we tend to end up using only the fixing unit.
According to government-set prices, a standard, genuine packer costs over 5,000 yen per meter, lol.
I guess the "real" part is a bit of a stretch... lol
Next time, I'll write about compression anchors.
See you later.
