Are Exams Pointless, Honestly? Why the Maximum Load-Holding Time Is What Really Matters | The Truth About Ground Anchor Tension Management
Hello, everyone. This is Enta. Obon is over, so I imagine things are finally back to normal on the job sites. The weekend is just around the corner! Let’s keep up the good work. lol Anyway, I wrote an article a while back about stress management for ground anchor workers. Ground anchors…
Where Are the Mistakes in Ground Anchor Installation? The Complete Guide | How to Create Anchors That Won’t Come Loose: Drilling, Grouting, Tensioning, and Head Finishing
Hello, everyone. This is Enta. I wrote a series on construction errors involving ground anchors on this blog back in 2018, and I rewrote it again in 2023, but to be honest, both versions ended up feeling a bit half-baked, lol. This time, when I reread my old posts, I thought, “Wait, this…”
The Fixed-Point Problem in Ground Anchor Tension Control | Displacement Measurement Is Difficult
Hello, everyone. This is Enta. When managing stress in ground anchors, we look at the load and the amount of elongation, right? It’s not enough to just look at the load cell and say, “Okay, that’s good.” We also check how much the prestressed steel strands have elongated and whether there are any unusual deviations from the design elongation. Basically, this is important, isn’t it? Qualification tests and…
What Is Set Loss? | How Tension Stabilization of Ground Anchors Reduces Load and On-Site Countermeasures
Hello, everyone. This is Enta. Young engineers often ask me, “Is set loss really necessary?” Come to think of it, even though the term “set loss” is thrown around all the time on job sites, there are actually a lot of people who’ve never had it properly explained to them. Back in the day, when I was installing ground anchors…
Is it really necessary to attach a dial gauge to the compression plate in ground anchor construction? An explanation from a veteran’s perspective for beginners lol
Hello, everyone. This is Enta. When you’re tensioning ground anchors, you attach a dial gauge or digital meter to the jack side, right? That’s to measure the elongation of the prestressed steel strands. It’s not enough to just check the tension load—you need to verify both the load and the elongation. For beginners…
I've written a detailed description of the procedures for tension control in ground anchor construction.
Hello, everyone. This is Enta. I’d like to outline the procedures for tension control in ground anchor installation. ■ Purpose of Tension Control The tensioning (pulling) of ground anchors is performed to apply tension to the installed prestressed steel strands and to verify that the force is being effectively transmitted to the ground through the anchorage…
The Actual Installation Location for Ground Anchor Work Is... Not What I Expected! (Part 1)
Hello, everyone. This is Enta. Do you know the actual location of ground anchors? Huh? You’re probably thinking, “What are you talking about?” lol. As a construction manager, you measure the anchor installation location based on layout tolerances, right? But layout tolerances only apply to the final head position…
Movement of the Dial Gauge
Hello, everyone. It’s Enta here. Well, it’s another weekend off this week, lol. Seriously, there have been way too many long weekends this year—I can’t seem to get my work done. Are your project deadlines getting pushed back? Anyway, today I’ve got a video showing how a dial gauge moves when managing tension, lol. Some of you might be thinking, “What on earth is that?!”…
Personally, I think the aptitude test is pointless, so I believe the maximum load-holding time on the verification test is what really matters.
Hello, everyone. This is Enta. Work starts again tomorrow, doesn’t it? Let’s try to shift our mindset a bit today! Don’t let *Sazae-san* get you down, lol. Anyway, when it comes to ground anchor construction, you’re managing stress, right? Things like suitability cycle tests and confirmation tests. First…
