How to Make a Packer for Ground Anchor Construction (Part 6)
Hello, everyone. This is Enta. I do a lot of construction training and instruction at our job sites. Just the other day, someone came all the way from Yamagata to conduct a training session on the Moldam method. Next month, I’ll be heading out to another company to provide instruction on rotary percussion construction. I’ve been getting more and more of those kinds of jobs lately, lol. Well…
Inexpensive Earplugs Are Also Highly Effective for Noise Protection | Hearing Protection at Construction Sites
Hello, everyone. This is Enta. I’ve been drilling anchor holes again for the past few days—are you all wearing earplugs? Back when I was a foreman, I wasn’t always in noisy environments, so I didn’t wear them. But lately, I’ve been using the ones shown above. Before that, I used…
Consult with Contractors When Selecting Machinery for Slope Construction | The Importance of Consulting During the Design Phase
Hello, everyone. This is Enta. Every few years, we come across a design that’s a little unusual, lol. I’m talking about ground anchor installation using a rotary drilling rig. It’s also known as a spindle-type drilling rig. These days, we use it for grouting and soil testing, and with larger machines, we use down-the-hole hammers…
How to Make Your Machinery Last Longer | Maintenance
Hello, everyone. This is Enta. Do you do anything to keep your machines from breaking easily? Well, the answer is not to use them at all (lol), but then they wouldn’t be machines—they’re only machines when you use them! So, I’m going to write about how to use them so they don’t break easily. …
If the Hydraulic Pump Fails, the Hydraulic Machine Is Done for | Maintenance
Hello, everyone. This is Enta. The other day, a hydraulic pump broke down on site lol. And it happened right when we only had two ground anchors left to go... lol. So, we had to swap out the machine on the fly, and we managed to get the drilling done somehow. However, we had to replace the pump with a brand-new one. And man, that thing was ridiculously heavy to lift…
Hydraulic Oil Flow Meter | Maintenance Tools
Hello, everyone. This is Enta. Have you seen this before? With this, you can measure hydraulic flow. It’s a hydraulic flow meter. Apparently, there aren’t any made in Japan—it’s a specialty item manufactured overseas. It’s a bit pricey, but it helps me fine-tune the performance of my rotary percussion tool…
The Right Mindset Is Key When Teaching | Guidance from a Slope Construction Specialist
Hello, everyone. This is Enta. Today, we welcomed yet another ground anchor technician—a young guy who’s just turned 20. Well, technically, he’s only “20” as of today, lol. I was feeling a bit irritable while teaching him this morning, and that must have come across, so neither of us was able to teach or learn very well…
I Tried Making a Drain | On-Site Improvement
Hello, everyone. This is Enta. The other day, I set up a drainage system at the company’s construction site. Well, to be honest, all I did was dig some holes with a rotary percussion drill and fill them with crushed stone, lol. This area used to drain well, but it seems the soil has compacted over time, causing poor drainage. …
The Challenging Task of Replacing Rails | A Maintenance Challenge
Hello, everyone. This is Enta. For the past few days, I’ve been replacing the rails—a key component of the rotary percussion mechanism. After prolonged use, the rails tend to wear out. Since the cam follower runs along the rails, they end up getting dented. (I forgot to take a picture of that, though.) …
