The Big Picture | A Slope Engineer’s Big-Picture Perspective
Hello, everyone. This is Enta. It’s raining today, isn’t it? So, I’d like to take it easy, but that’s not really possible, haha. I’m working on compiling the data from the qualification test we conducted the other day and organizing the photos. Thankfully, there’s no work going on at the site today, so I’m able to focus on the paperwork. &n…
A Discussion of the Thermal Expansion Coefficients of Steel, Concrete, and Polyethylene
Hello, everyone. This is Enta. A while back, I put together some materials addressing the question: “Is there a reason to use steel spacers (PC spacers)?”—specifically, why they’re made of steel. “It’s because the thermal expansion rates are different, so there’s less risk of cracking.” Well…
The Future of a Company Lies in What It Does Today | The Essence of Management
Hello, everyone. This is Enta. Work on next year’s construction projects is already underway, and I’m being consulted on design changes and the wording to include in meeting minutes.

Drilling Limits with Spring Drills (Part 2) | Continued Analysis
Hello, everyone. This is Enta. Regarding the spring drill boring I posted about the other day—it actually went well in the end, lol. It was a 17-meter borehole in sandy soil. The borehole diameter was φ115. It went surprisingly smoothly. (There’s a trick to it, lol.) Well, since the drilling angle was a vertical 90 degrees this time, I thought…
Let's Boost the Economy Starting with the Construction Industry | Revitalizing the Industry
Hello, everyone. This is Enta. While the world is in a state of self-restraint due to the coronavirus, our slope stabilization industry seems largely unaffected and is continuing to operate as usual. This is especially true for slope construction projects, which are mainly carried out in mountainous areas. However, we need to be especially careful when going out to run errands…
Negative but Useful Information | From the Slope Specialists
Hello, everyone. This is Enta. The other day, at a meeting, I ended up being appointed chairperson of a small group. That got me thinking. Among the various people there, a few of them said things like, “This role is tough,” “It’s going to be a lot of work!” and “Are you sure you can handle it?” after the decision was made…
This Is Still a Time When We Must Remain Vigilant | Safety Awareness
皆さんこんにちは。 エンタです。 先日のブログのタイトルを入れるのを忘れていたようでｗ 気付いたのが先日の20時。 確かに眠さでもうろうとしてブログ書いていました。 やっぱ削孔は疲れるなぁーと思うのと反面に体力が落ちてる？ って思うんですよ…
A Good Director | An Evaluation from a Slope Maintenance Specialist's Perspective
皆さんこんにちは。 エンタです。 先日現場から送ってきた写真です。 刃先が丸くなってますｗ 通常がこんな感じで尖っています。 ダブルコニカルという形状のビットを使用していますが、ここまで丸くなることはまず無いですねｗ 以前、硬…
Embracing Failure | Rethinking the Mindset in the Construction Industry
皆さんこんにちは。 エンタです。 この時期になると忙しすぎて心が折れそうになりますよね？ そして、実際に折れる方もいて最終的にトンデモナイ事になることもありますよね。 私自身心が折れるとかって無いんですｗ だいたいイヤになるって位までです。…
