Site Supervisors Work for the Future | Checklist for Beginner Supervisors
Hello, everyone. This is Enta. Today’s blog post is a little late. Lately, as I’ve been out on site, I’ve gradually been getting back into the swing of things. And, of course, my fatigue is reaching its peak, haha. Mornings are tough… But anyway, let’s talk about on-site planning. When it comes to managing a project, it’s important…
About Crack-Prevention Materials (Part 3) | Toughlight RG One-Week Strength
Hello, everyone. It’s Enta. The other day, I dropped my phone in the river at the job site... lol. It got swept away by the muddy current... sob. Anyway, when I tried to locate my iPhone, the GPS was picking up a signal, but the coordinates were vague. I’m thinking of going to check it out sometime soon. Bored…
Head Treatment for Ground Anchor Construction
Hello, everyone. This is Enta. Today, I took a little trip out of town and came to Yamanashi. It’s been a while since I’ve been here. It reminds me of when I used to work on a large-diameter full-casing method (Benoto piles) project in Ōtsuki City, Yamanashi Prefecture. Back then, I was stuck on an emergency site for the Chuetsu-oki Earthquake in Niigata Prefecture for about eight months…
Suspended Drilling Rig: Tips for Drilling
Hello, everyone. This is Enta. Lately, I’ve been drilling away like crazy with a suspended core drill. So, I want to talk about a little issue with slurry discharge that’s pretty easy to run into.

About Crack Prevention Materials (Part 2) | Ground Anchor Installer Certification Renewal
Hello, everyone. This is Enta. The other day, I attended a refresher course to renew my Ground Anchor Installer certification. The instructor in Nagoya is a senior technician I look up to—someone I often call when I’m stuck at work. He explains things so clearly that I end up calling him all the time, lol. I’m always grateful…
About Crack-Prevention Materials (Part 1) | Comparison with Nafuroku
Hello. This is Enta. I thought I’d posted this the other day, but it turns out I hadn’t. My apologies. I’d like to introduce a product I tried while testing various crack-preventive materials that I thought was pretty good. I think Nafuroku is the one most people use frequently. With a simple formwork…
Types of Bits for Suspended Drilling Rigs (Part 2) | For Clay Formations
Hello, everyone. This is Enta. In response to a question from my recent blog post, someone asked what to do when you encounter loose clay layers. In reality, the only option is to drill slowly while keeping an eye on the slime, but these days, there are actually some pretty good drill bits out there. Haha. This one here…
Types of Bits for Suspended Drilling Rigs | Measures for Drilling in Rainy Weather
Hello, everyone. This is Enta. It’s been raining in Aichi Prefecture for the past few days. And today, for the first time in a while, we’re drilling with a suspended drill rig. Drilling on a rainy day is really tough, isn’t it? It’s kind of cold, kind of hot, and really muggy—I can’t tell if it’s sweat, rain, or just the humidity! Plus, when we’re drilling, the slope gets dirty, so…
I want to reduce mechanical friction!
Hello, everyone. This is Enta. The Timken Test (Timken) — At the end of last month, we conducted an experiment on oil at our sales office. Have you ever seen a device like this? Apparently, it’s commonly known as the Timken Test (Timken Test). The round part in the middle is a motor…
