How to Use the New Bolt Scale | An Enhanced Tool
Hello, everyone. This is Enta. I work as an anchor installer, and at the job site, we were using the bolt scale in a new way—or so it seemed. We check for alignment errors before drilling, and during that process, we place the bolt scale as shown in the photo, align it with the string using a plumb bob, and measure the displacement…
Look closely! Look very closely! The keen eye of a slope engineer
Hello, everyone. This is Enta. We’re still under fuel restrictions and unable to drill, so it’s a tense situation. In times like these, there’s one thing that’s absolutely essential. That is, observing. It’s not enough to just look at what’s immediately visible. You have to carefully observe and assess the situation around you…
Be Very Aware of Displacements in the Natural Ground During Abnormal Conditions | Vigilance at the Site
Hello, everyone. This is Enta. I suppose I’m what you’d call a “disaster victim”? I haven’t suffered any injuries, and the area where I live still has electricity and water. It’s just that we’re out of fuel. And food is a bit scarce, I guess? Fuel rationing has been implemented, so we’re only allowed 5 liters of gasoline and 10 liters of diesel…
What Will Happen Today Due to the Earthquake? | On-Site Response in Emergencies
Hello, everyone. This is Enta. I was woken up by a massive tremor just after 3 a.m. this morning. That was followed by a power outage and a water outage. The area where I live is probably a Seismic Intensity 5–6 zone, so was this the area that shook the hardest? Is everyone okay? Are those affected by the disaster all right? …
How to Make the Job Site More Enjoyable | Motivating Slope Workers
Hello, everyone. This is Enta. The typhoon is getting absolutely out of hand. The winds seem to be really strong. Here in Hokkaido, business is as usual. Is Hokkaido just more resilient to disasters?? But anyway, design consultants generally don’t consider issues like constructability. When it comes to construction, the contractors are the ones who decide, “Let’s do it this way…”
The embedment length must not exceed 10 meters | Standards for Anchor Design
Hello, everyone. This is Enta. Something pretty shocking happened recently—it has to do with my work on temporary anchors. The design load exceeds 1,000 kN. Well, I suppose that’s fine as long as the design is sound. But when I took a closer look at the drawings…
Calibration (Adjustment) of the Mad Balance | Ensuring Accuracy
Hello, everyone. It’s Enta here. People often ask me, “How do you manage to write every day!?” Well, that’s exactly it. I do write every day, but I really have to rack my brain for ideas, lol. Sometimes I run out of ideas. That’s actually pretty tough, you know~ So, a friend of mine asked me about 〇〇…
What's Underneath the Wash Water? | On-Site Environmental Management
Hello, everyone. This is Enta. On construction sites, you usually put cement slurry and the final rinse water from the spray machine into flexible containers (the cheap kind), right? I’ve always wondered if there’s a way to drain just the water without letting any cement out. There’s even a tray you can place underneath to catch the rinse water…
Beware of Overzealous Construction Management | The Pitfall of Excessive Quality
Hello, everyone. This is Enta. Here in Hokkaido, the weather’s been terrible—it keeps alternating between rain and clear skies. And when it rains, it gets cold, but when it’s cloudy, it’s muggy. (Since I’m wearing a raincoat.) I wish it would just stick to one or the other, lol. Anyway, moving on… Unnecessary construction management. There’s a lot of management work that makes you wonder, “Is this really necessary?”…
