Applications of Displacement Data from Pressure-Bearing Structures | Utilizing Measurement Data
Hello, everyone. This is Enta. Until just the other day, Hokkaido was enjoying absolutely beautiful autumn weather, wasn’t it? It gets pretty chilly in the mornings and evenings, but the weather is pleasant overall. I’d like to make sure I don’t get sick from the temperature changes. Today, though, it’s cloudy and drizzling a bit. But enough of that. Why do we measure the sag of the load plate…
Cracks in the Backfill | Problems Under the Load-Bearing Slab
Hello, everyone. This is Enta. Here in Hokkaido, the leased machine we rented has been having one problem after another and is basically out of commission lol. Our in-house machine is running smoothly, thank goodness... but what a waste of lease money. We plan to wrap things up after we finish two more holes. It’s getting really tough to keep an eye on it. It’s a job site where one machine would be plenty, but they forced two in there…
Here's What to Watch Out for When Using a Jack Under Stress!
Hello, everyone. This is Enta. Sorry for posting nothing but anchor work lately, lol. A lot of people tend to mess this part up. You know what I’m talking about, right? This isn’t a securing wedge—it’s the wedge used on the jack head. This one tends to get stuck a lot. …
Reasons Why Stress Management Fails
Hello, everyone. This is Enta. The other day, my hydraulic hose burst, and it took me three and a half hours round trip to Sapporo... My butt was killing me, lol. But anyway, why does stress management often fail? Don’t you all think it’s pretty difficult to manage? You’d probably think it’d be a big problem if government officials took photos or notes of your numbers and results, right…
This Is the Best Filler for Anchor Head Treatment | Field Test Results
Hello, everyone. This is Enta. Lately, since I’m working as a craftsman, I haven’t been interfering at all with on-site construction management—I’ve just been quietly doing my craft—but the general contractor keeps asking me all sorts of questions. They’re asking me, a craftsman, about construction management, lol. And there’s another person on our team—one of our super-veteran construction managers—who’s also been working as a craftsman, but…
Pressure Does Not Rise During Casing Pressurization; Pressure Escapes from Outside the Casing | Investigating the Cause
Hello, everyone. This is Enta. The other day, I received some feedback regarding the grouting process—I believe it was from an employee of the client’s construction management company. I’ll explain this in more detail below. 1. Drilling complete 2. Inner rod removed 3. Anchor inserted 4. Cement slurry injected through the grouting hose (…
Trying Out a New Stress Management Method | Technological Innovation
Hi, everyone. It’s Enta here. I’ve been trying to manage my nerves since last week, lol. You guys often fail at managing your nerves, don’t you? lol. I’ve made plenty of those same mistakes myself. I totally get it. “It won’t fit within the upper and lower limits!” “The hydraulic stroke isn’t long enough!” “Aaaahhh… wa…”
How to Use the New Bolt Scale | An Enhanced Tool
Hello, everyone. This is Enta. I work as an anchor installer, and at the job site, we were using the bolt scale in a new way—or so it seemed. We check for alignment errors before drilling, and during that process, we place the bolt scale as shown in the photo, align it with the string using a plumb bob, and measure the displacement…
The embedment length must not exceed 10 meters | Standards for Anchor Design
Hello, everyone. This is Enta. Something pretty shocking happened recently—it has to do with my work on temporary anchors. The design load exceeds 1,000 kN. Well, I suppose that’s fine as long as the design is sound. But when I took a closer look at the drawings…
