On Hole Deformation During Drilling in Rotary Percussion Machinery
Hello, everyone. This is Enta. I wrote about drilling angles in dewatering borehole construction. What is the approach to angles in dewatering borehole construction? In that context, I received a question about casing deviation. I’d like to explore this based on the relevant materials…
If the cement slurry turns out too stiff when you're making it, don't add just water!
Hello, everyone. This is Enta. When you’ve mixed a few batches of grout, the grout left in the mixer tends to get pretty hard, right? What do you do in that case? This video shows what happens when you add something to that hardened grout! At first, it’s all clumpy…
We've discovered a ground anchor method that can reduce carbon dioxide emissions! (Innovation)
Hello, everyone. This is Enta. Have you seen this before? It’s a load-bearing element. A temporary wooden anchor load-bearing element. It’s amazing, isn’t it! I thought, “It’ll rot away after installation!?” but since it’s actually covered in cement slurry, that won’t happen, lol …
Where Is the Construction Error in the Ground Anchor Work? (Part 4)
Hello, everyone. This is Enta. I’ve been meeting with my blog readers quite often lately, and I’m really happy about that. Even though I feel a bit of pressure knowing you’re looking forward to it (lol), talking about slope stabilization is a lot of fun ^^ I’ll continue to share useful on-site tips with you all as much as I can…
Where Is the Construction Error in the Ground Anchor Work? (Part 3)
Hello, everyone. This is Enta. Wow, there’s hardly anyone here, huh? lol I’m so swamped I can’t even move a muscle! Still, I’ll do my absolute best within my capabilities! I’m really hoping everyone involved will let us extend the schedule a bit, lol. Anyway, moving on to Point 4: Tension Work. A construction error in tension management…
Where Is the Construction Error in the Ground Anchor Work? (Part 2)
Hello, everyone. This is Enta. I was in the Kanto region starting last Thursday. I went to a job site run by one of our group companies to inspect the site and decide on various directions moving forward. It was a tough site that would be a real challenge unless we tweaked our approach a bit, so I went to check it out (lol). With difficult sites like this, getting off to the right start is crucial…
Where is the mistake in the ground anchor installation?
Hello, everyone. This is Enta. It seems to be getting a little cold again, doesn't it...? The seasons are all over the place here in Japan! lol By the way, would you like to work at Enta? I'm serious! I really mean it!! We do get some prank emails asking, "Are you hiring?" though...
For ground anchor construction, an initial load of approximately 0.1 to 0.2 during tensioning is sufficient.
Hello, everyone. This is Enta. Since I was asked, “What exactly is initial load?” I thought I’d write a post about it. In the book *Design and Construction Standards for Ground Anchors and Explanatory Notes—Standards of the Japanese Geotechnical Society*, it states, “The tensile force applied to the tendon when tensioning and anchoring the anchor…”
It's Super Easy! Tips for Tension Management in Ground Anchor Construction
Hello, everyone. This is Enta. The Process of Construction and Construction Management for Ground Anchor Projects. The other day, I wrote about the process involved in ground anchor projects. I think it probably seemed like there weren’t many sources of fear or anxiety in ground anchor projects. However, in reality…
