Hello, everyone.
This is Enta.
Today, I finally took the tension test for ground anchors, which I wrote about earlier, and
Video of the moment the anchor comes looseWe will publish it.
Please take a look for now.
Finally, there was a "pop," and it came out.
The way this comes off is,The bond between the cement slurry and the prestressed steel strands failedHere's how to remove it.
The reason is that when the bond between the natural ground and the cement slurry breaks, the ground gradually gives way.
Even when a load is applied, the load decreases slowly.
However, in this case, the "pop" sound occurred at the exact moment when the load caused the bond between the PC steel strands and the cement slurry to break.
I doubt you'll ever get to see this miraculous video. It's really rare footage, lol (patting myself on the back).
I was commissioned by another company to perform stress analysis, but the anchors at this site pull out under loads less than half of what was specified in the design.
Since its behavior seemed suspicious at the time, I decided to record a video just in case.
And then I managed to slip away just as planned, lol
Seventy percent of the installed units have come loose.
Probably a construction errorThat's it.
As long as ground anchor work is carried out according to standard procedures, construction defects are virtually nonexistent.
That's because the installation itself is simple, so there are few mistakes.
I'll cover the common mistakes next time.
By the way, we had the anchor here re-installed at Enta.
See you later.
