Basic Structure and Principles of Ground Anchor Systems — What Exactly Are Ground Anchor Systems? —
Hello, everyone. This is Enta. I’d like to give a brief explanation of ground anchor construction. ~The invisible force that stabilizes the ground through tensile force~ Ground anchor construction is a method that stabilizes and secures the ground or structures using a “pulling force” (tensile force). Slope failures and retaining walls…
[Comparative Guide] Rebar Insertion vs. Ground Anchors vs. Retaining Piles (For Newcomers)
Hello, everyone. This is Enta. In this post, I’d like to compare the “Big Three” in slope stabilization. (It took me a whole hour just to draw this picture… lol) “Reinforcement Insertion,” “Ground An…,” and other methods you often hear about as countermeasures against slope disasters such as rockfalls and landslides…
How to Remove Unnecessary Ground Anchors
Hello, everyone. This is Enta. How to Remove a Zabuton Frame and Relieve Load from Ground Anchors. In my previous post, I wrote about how to relieve load from ground anchor bolts. This time, I’ll explain how to relieve load at the anchor head. You’ll need acetylene gas and acid…
How to Remove the Zabuton Frame and Unload the Ground Anchors
Hello, everyone. This is Enta. Do you know how to relieve load during ground anchor installation when zabuton frames are in place? I’ve actually experienced this once myself. During construction, the embankment slid, causing the anchors to become over-tensioned. At that time, 1…
Just don't add 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…
Field Notes on Ground Anchor Construction, Part 1 (Soil Cover)
Hello, everyone. This is Enta. The other day, a general contractor asked me, “How much soil cover is considered problematic for ground anchors?” I thought it was 3 meters, if I remember correctly… but when I looked it up, it turned out to be 5 meters. I really tend to forget things these days. Design and construction of ground anchor works…
You can't just cut corners when it comes to legal loopholes!!
Hello, everyone. It’s Enta here. I’ve been working on concrete projects lately, so I’m super sensitive to the weather lol. “Will we be able to pour the concrete!?” “If we can’t pour it here, the schedule will be in trouble…” I’m thinking all this while I’m doing paperwork at the office lol. Anyway, the other day at a job site, there was one thing that was just a disaster…
What's the best part of drilling operations?
Hello, everyone. This is Enta. We’re drilling using drill bits, right? Here’s what a brand-new one looks like. It’s a standard ring bit. We want to use this for as long as possible, but we also want to drill as quickly as possible. So we tend to apply quite a bit of pressure while drilling…
The Real Reason It Comes Out From the Outside of the Casing After Pressure Injection!
Hello, everyone. This is Enta. Are you doing pressure grouting? Well, I’ve always said that pressure grouting isn’t all that effective, but since the topic of “Why does it come out of the mouth?” came up, I thought I’d write about it. Drill the holes as usual, and for ground anchors or…
