How to Calculate Estimated Costs | A Practical Example of Cost Calculation for Rock Bolt Installation
Hello, everyone. This is Enta. (This is a reprint of an article from fiscal year 2016.) The other day, I heard from the anchor shop; they said they wanted to provide more accurate estimates. As expected, when you transition from being a sole craftsman to an organized business, these kinds of issues tend to come up first. Providing accurate estimates…
Timing of Packer Injection
Hello, everyone. This is Enta. In ground anchor construction, we inject cement slurry into areas riddled with cracks (joints). But it just leaks out like crazy, so no matter how much slurry we have (I’ll just call it “slurry” from now on), it’s never enough lol. That’s where the packer comes in…
Drilling through clay and silt is very difficult.
Hello, everyone. This is Enta. Something new is starting again tomorrow! Stay tuned^^ Anyway, when I’m installing temporary anchors, I always get stuck in that sandy silt lol. Plus, it’s packed pretty tightly, so when I hit it with a hammer, the tip gets clogged. The most…
Using jigs designed specifically for construction management makes it easier to explain the process and helps me gain a deeper understanding of it myself.
Hello, everyone. This is Enta. When it comes to measuring placement errors in rebar installation, bolt scales have become the standard. Sometimes older supervisors joke, “Thanks to this thing, we have to keep track of everything now,” lol. I understand how they feel, but then what about before…
Found a Great Product! (The Futuristic Appeal of Ground Anchor Construction)
Hello, everyone. This is Enta. I just wrapped up a project the other day. It was my first time seeing this, too. This is great. It’s really great!!! That’s right!! This one!!!! It really has a futuristic feel to it, doesn’t it? It’s so beautiful and easy to understand. The fact that it’s oil-free is another plus…
I Went to the 2024 Chubu Construction Technology Fair! (Part 1)
Hello, everyone. This is Enta. I went the other day to the annual Construction Technology Fair! in Chubu. I went on the first day. These days, most technology fairs are all about ICT and digital transformation. So, it wasn’t really anything new, haha. Well…
When it comes to earthquake countermeasures for ground anchor construction, I feel like all we need to do is replace the caps...
Hello, everyone. This is Enta. When you’re driving on the Shin-Tomei Expressway, you come across anchors like this. The other day, I happened to be stuck in traffic due to an accident, so I took a picture of it lol. The anchor cap on top is in a pretty wild state, isn’t it? It’s even connected to the one next to it lol…
The Actual Installation Location for Ground Anchor Work Is... Not What I Expected! (Part 2)
Hello, everyone. This is Enta. The actual installation location for ground anchors is... not what you’d expect! (Part 1) This is a continuation of the previous post. Do you know a method to quickly eliminate variations caused by tension? What kind of variations, you ask? Well...
We’re constantly researching and updating the standard construction methods we use on a daily basis!
Hello, everyone. This is Enta. To everyone who attended the briefing on dewatering rock bolts—thank you so much. During the Q&A and discussion session, I heard opinions I hadn’t even considered, and I’d like to use them as a reference moving forward. This includes the creation of guidelines and refining the design…
