M's EDH3.5 Drifter Review | Key Evaluation Points in the Field
Hello, everyone. This is Enta. Have you heard of this? It’s a machine called the EDH3.5. As you can probably tell from the name, it’s M’s Drifter. We used it on site after securing it very firmly in place. Basically, it’s a core-drilling machine with a hammer mounted on top…
Introducing the Industry’s First Innovative Casing | Changing the Norms of Slope Construction
Hello, everyone. It’s Enta here. Do you guys know what this is? It might be pretty rare to spot this at a glance, lol. This is an outer casing for a φ65!! That’s right. It’s the one and only one of its kind in the world—and it even comes with an inner casing! Drilling…
A Slope Where Reinforcing Bars Were Installed | A Phenomenon Where the Topsoil Is Washed Away, Leaving the Slope Bare
Hello, everyone. This is Enta. This is the casing from a self-drilling rock bolt, lol. This is a site where slope stabilization work was carried out to prevent surface slippage. Slope frame + self-drilling rock bolts. The reason for selecting self-drilling rock bolts is likely because the borehole walls on this mountain aren’t stable enough to stand on their own. In fact, this mountain is experiencing advanced sandification…
Pros and Cons of Ultra-Lightweight Drilling Machines | A Thorough Review by Slope Specialists
Hello, everyone. This is Enta. The 65kg drilling rig I introduced the other day turned out to be an ultra-lightweight model that can be operated with a crab crane, lol. Since we’re currently in the middle of a project, I can’t show you too much of it, but here’s what it looks like. The crab crane in the photo is the MC305C-3 from Maeda Manufacturing…
Apply Cement Slurry from the Bottom Up | Instructions for Slope Construction
Hello, everyone. This is Enta. It’s been getting a little warmer lately. That said, it’s still cold on site, lol. Things are going to stay hectic for a while longer, so please take care, everyone! But enough of that. Today, I’ll be talking about grouting in anchor work. Grouting is the most important part of anchor work…
Ultra-Lightweight Single-Drill Machine (65 kg) | Boost On-Site Efficiency with Its Remarkably Lightweight Design
Hello, everyone. This is Enta. Here’s the air-powered drilling machine I’ve been experimenting with lately. At first glance, it looks like a typical drilling machine. The reaction force is counterbalanced by its own weight and the wires on the sides. However, the best thing about this machine is how light it is. I’m still experimenting with various things…
Drilling a Single Hole in a Non-Self-Supporting Mountain | What We Gain from Challenging Sites
Hello, everyone. This is Enta. I’m really stuck on this job right now, lol. It’s supposed to be single-pipe drilling, but this isn’t the kind of slope where you can actually drill with a single pipe—it can’t be done without double-pipe drilling! If I try to drill with a single pipe, it just collapses right away. The borehole walls in the natural ground start to…
Design Changes for Similar Construction Methods Are Easy | An Era of Freedom in Choosing Slope Stabilization Methods
Hello, everyone. This is Enta. Lately, we’ve been shifting our focus slightly away from ground anchors to work on steep slope stabilization projects, where we’re using a method called the “unit net method.” Simply put, it’s a method where the heads of the rebar inserts are connected using wire or similar materials. Different companies have various methods…
Placement Locations for Rebar Insertion Workers | An Approach to Solving Difficulties Through Lateral Extension
Hello, everyone. This is Enta. Do you know the basic principles behind rebar placement? You often see areas where concrete is poured and others where it isn’t, right? As long as the foreman is aware of this, there’s usually no problem, but there are often situations where you wonder, “What should we do here?” or…
