Risks and Troubleshooting in Grouting Operations (Part 1)
Hello, everyone. This is Enta. In rebar insertion and ground anchor projects, we inject cement slurry. If the cement slurry keeps flowing in, how far should we inject it? For example, suppose there is a rebar insertion project with a borehole diameter of 90 mm and a depth of 5.0 m. The injection volume is …
Is it better to rotate technical intern trainees at regular intervals, or is it better to keep them employed for a longer period?
Hello, everyone. This is Enta. Something’s been on my mind lately. It’s about technical intern trainees—is it really necessary to switch to the “Specified Skilled Worker” system? Going forward, I suppose we’ll have two systems: something to replace the current technical intern trainee program and the “Specified Skilled Worker” system. It’s not that I’m looking for cheap labor or anything; it’s just that people coming to Japan…
Mechanics in Everyday Life | Considering Buckling and the Load-Bearing Area of Single-Pipe Scaffolding
皆さんこんにちは。 エンタです。 今日は座屈と言う言葉を考えて見たいと思います。 座屈。 知っていますか？ 座屈（ざくつ、buckling）は、構造物に加える荷重を次第に増加すると、ある荷重で急に変形の模様が変化し、大きなたわみを生ずること…
Understanding Connections from a Three-Phase 200V Capacitor
Hello, everyone. This is Enta. The other day, I installed a power supply for the winch. Since it’s three-phase 200V, there are four wires: three phase wires and one ground wire. If you don’t connect these properly, the polarity might reverse or the winch might not deliver any power. This can actually cause some unexpected problems on site, so…
What do you think of a system that pays Specific Skilled Workers wages equal to or higher than those of Japanese workers?
Hello, everyone. This is Enta. Recently, I’ve been handling the procedures and applications for technical interns to switch to the Specified Skilled Worker status. The Technical Intern Training Program itself has been facing a wave of public criticism, and it looks like the program will be phased out next year. And going forward (from 2024 onward)…
Let's take it easy after Obon and aim to stay injury-free!
Hello, everyone. It’s Enta here. The other day, I went for a run on Mt. Kinka lol. I thought it would be a piece of cake, but the course started with a steep climb of about 650 meters, and it was absolute hell. Man, I never thought I’d end up in the mountains for anything other than work lol. Mission accomplished…
There’s absolutely no way my craftsmanship has gotten worse since yesterday!
Hello, everyone. This is Enta. Has the Obon holiday ended for you yet? Is today your first day back at work? It varies from person to person here. Or rather, it depends on the worksite. For those starting work today, don’t push yourself too hard—just take it easy. There’s no point in getting injured on the very first day. But anyway…
It's Better to Drain a House from Further Inside (For Single-Family Homes)
Hello, everyone. This is Enta. The other day, I went to check on a stone masonry site we worked on last month. Since there had been heavy rain due to the typhoon, I went to check for rising pore water pressure (lol). We installed drainage in areas where the internal pressure of the stone masonry had risen due to the heavy rain and was threatening to collapse. …
On a typhoon day like today, the golden rule is to stay home and take your time doing something—and definitely don’t go outside!
Hello, everyone. This is Enta. It’s the Obon holiday—how are you all doing? As usual, I’ve been making the rounds at the office, then coming home to zone out a bit, take a nap, and get some work done. Since we’ve had a lot of private-sector construction projects lately, I’ve been reading books like this. …
