Machine for Removing Grout Residue | Quality Inspection
Hello, everyone. This is Enta. I’ve been insanely busy lately—I can’t take it anymore! It feels like things suddenly got hectic, and now my schedule is already packed to the brim—there’s just no way to handle it. It’s a real headache. I really wish they’d think more about balance when placing orders! But anyway, Ground An…
Signals and Calls Make It Possible to Work Even When You Can’t See Each Other | On-Site Coordination
Hi everyone, this is Enta. This week, I’m doing anchor drilling in Nagano. So, this is what it usually looks like when accidents happen. I took this photo myself (well, I’m the operator, lol)—what do you think? You can’t see anything, can you? It’s the blind spot of the crawler-type rotary percussion drill…
Concepts of Loading in Ground Anchor Construction | Design Fundamentals
Hello, everyone. This is Enta. Have you ever used a standby anchor in ground anchor construction? When asked that, you probably think, “Huh?” In ground anchor construction, there’s something called the design load. For example, let’s say the design load is 500 kN…
Trumpet Pipe Repair | Anchor Coating Protective Equipment
Hello, everyone. This is Enta. The other day, the bell end of a trumpet pipe I was using on site cracked lol. Since they just made the bell end and welded it to the female threaded part of the casing, it’s no surprise it came off. We also do a lot of downhole cleaning, so the internal weld broke, resulting in this lol. The welded part…
Material Inspection for Ground Anchor Construction | Ensuring Quality
Hello, everyone. This is Enta. I’ve been in Nagano for the past few days. Well, actually, I’m near our office here, working on a reverse-wrap installation. According to the design specs, the reverse-wrap method requires an additional 20%, but I’m wondering if that’ll be enough. Reverse-wrap installations are really tough, aren’t they? Anyway, moving on to the anchor material inspection…
Transportation of Rotary Percussion Equipment | Heavy Equipment Transport
Hello, everyone. This is Enta. At our last job site, we moved a 3-metric-ton core drill about 130 meters. If you’re not familiar with the structure of a core drill or the machine itself, you probably have no idea how we moved it. For those of you who aren’t familiar with anchor work, I’ll explain how we moved it this time lol &nbs…
When You Mess Up the Precise Head Position of a Tie-Down Anchor (Part 4)
Hello, everyone. It’s Enta here. I didn’t manage to schedule the post for my article the other day, so I was in a panic trying to get it up lol. That really gave me a scare. Anyway, moving on—in Part 3 of my previous series, I received a message asking if the jacks need to be replaced when upgrading to a larger apartment with a tie-back anchor. I suppose as for that…
Theoretically Reducing Tension Time | Improving the Efficiency of Anchor Tensioning
Hello, everyone. This is Enta. My eyes look like Colonel Muska’s. (See *Castle in the Sky*.) But anyway, to all you anchor installation supervisors out there—you aren’t actually waiting 60 or 180 minutes for the anchors to set, are you? Cycle, test load, minimum measurement…
When You Mess Up the Precise Head Position of a Tie-Down Anchor (Part 3)
Hello, everyone. This is Enta. Picking up where I left off last time, here’s a solution for when the SEEE head housing is too short to apply tension. There’s actually something like this! It’s a sort of bushing that you slip over the SEEE-specific head housing. Now, a bushing is…
