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…
Workflow for Construction and Construction Management in Ground Anchor Projects
Hello, everyone. This is Enta. What do you think is the most challenging part of ground anchor installation? From a craftsman’s perspective, the question is, “How should we go about installing them?” Right? However, the installation process itself is relatively simple. If you follow the steps and include the necessary management checks…
By teaching them the real thing, they can take on dangerous challenges in a safe environment!
Hello, everyone. This is Enta. Since last week, I’ve been teaching construction management—from drilling to tension control—for ground anchor projects. I’ve been going out to teach because I’ve been getting requests like this lately. Of course, it’s part of my job. Until now, this kind of know-how…
Here’s the one thing you must never do when using packers in ground anchor construction at locations with high groundwater pressure!
Hello, everyone. This is Enta. Do you know what this is? That’s right! It’s the remains of an anchor used in ground anchoring work, lol. It’s the result of a failed attempt, hahaha. We had two failed attempts at this site before. What I learned from this experience is that grouting…
Drilling through clay and silt is harder than I expected.
Hello, everyone. This is Enta. We’ve been doing dewatering drilling work for the past few days. I’ve been busy lately, so I’ve been heading out to the job site as an operator, but unlike in August, the temperatures have cooled down quite a bit, so it’s much easier on the body. This is the best time of year. Let’s stay safe out there! But enough of that…
I found a great product! (When used by an anchor operator, it allows for safe attachment and removal of the rod!)
Hello, everyone. This is Enta. Are you using this? This is a double wrench for rotary percussion tools. Regular double wrenches can be dangerous because they tend to fall off, but this one can be secured to the Exte side, so it absolutely won’t fall off. That’s why…
I still think digging with water is the fastest way to dig a hole!
Hello, everyone. This is Enta. These days, drilling is more about using water and air than just water, isn’t it? Water-only drilling used to be the norm. (Water and air is a more recent drilling method.) To clean the inside of the casing, we used to pour water liberally and move the inner rod up and down to flush it out…
