Here's How to Remove Damaged Ground Anchors! (Part 2)
Hello, everyone. This is Enta. Here’s how to remove damaged ground anchors! (Part 1) This is a continuation of my previous post. How do you relieve the load from the anchor head? When it comes to removing wedge-type and nut-type anchors, the easiest and most cost-effective method is to use gas…
Here's How to Remove Damaged Ground Anchors! (Part 1)
Hello, everyone. This is Enta. Take a look at this photo. It shows a ground anchor from the Noto Earthquake. In the photo above, a massive load-bearing structure has shifted—perhaps because the prestressed steel strands have snapped? They’ve snapped completely, severing the tie rod anchor and causing the head to come off. The tie rod you can see…
Remnants of Removable Temporary Ground Anchors
Hello, everyone. This is Enta. I get a lot of questions about removable temporary anchors, so I’d like to address them. “All removable anchors can be removed, right?” I get this question a lot, lol. When you look at a temporary anchor with a standard cross-section, it looks like this. The anchoring section features a load-bearing element like this…
When calculating the number of scaffolding workers at heights, the count starts from the bottom and works its way up!
Hello, everyone. This is Enta. Today, I’d like to talk about billing for scaffolding work. Scaffolding is often required when ground anchors or rebar inserts are installed at the top of a slope, isn’t it? For example, suppose there were ground anchors or rebar inserts in a location like the one shown below…
Movement of the Dial Gauge
Hello, everyone. It’s Enta here. Well, it’s another weekend off this week, lol. Seriously, there have been way too many long weekends this year—I can’t seem to get my work done. Are your project deadlines getting pushed back? Anyway, today I’ve got a video showing how a dial gauge moves when managing tension, lol. Some of you might be thinking, “What on earth is that?!”…
How to Read a Dial Gauge
Hello, everyone. It’s Enta here. Lately, I’ve been focusing all my strength training on my legs, so I look like a little fawn now lol. Working out is tough, but if it helps my lower back, it’ll be worth it, so I’m going to stick with it for a while ^^ Anyway, moving on... You know what a dial gauge is, right? Slope contractors don’t need one...
Drilling with cement slurry in ground anchor construction
Hello, everyone. This is Enta. I’m so happy to hear that a construction site we worked on as a first-tier subcontractor this spring was recently recognized!! The general contractor was thrilled and reached out to let us know. I’m just so happy! This is what makes being a subcontractor so rewarding. The general contractor gets recognized by the local government, and we get recognized by the general contractor. I’ll work even harder…
Drill holes directly into the zabuton frame
Hello, everyone. This is Enta. As I mentioned the other day, I went ahead and filmed a video showing how to cut the opening for the zabuton frame. Do you really need a cutout for the zabuton frame? Since there’s no rebar running through the center, it cuts out cleanly. Seeing this, I guess a cutout really isn’t necessary after all…
How to Calculate Cement Slurry and the Loss Rate
Hello, everyone. This is Enta. I used to have a grout calculation website, but I shut it down, so people still mention it to me from time to time lol. So, I’ll list the minimum necessary coefficients here. However, since that alone would make the calculation method a bit bland, I’ll include the full method as well. Borehole diameter (…
