Should the road be sloped or level when installing ground anchors or reinforcing bars?
Hello, everyone. This is Enta. Which is better for ground anchor installation and rebar insertion: installing formwork or pressure plates? Why it’s best to install formwork level (horizontally) on-site. I’ve written about this before, but the same applies to formwork, lol. Road gradient…
It means they're selling construction services
Hello, everyone. This is Enta. You know those anchor pins used in retaining wall construction, right? There’s usually one at the intersection and about two to six on the crossbeams. Even when installing rock bolts or ground anchors in the center, they’re driven into the ends of the intersection. Rock bolts…
Field Notes on Ground Anchor Construction, Part 1 (Soil Cover)
Hello, everyone. This is Enta. The other day, a general contractor asked me, “How much soil cover is considered problematic for ground anchors?” I thought it was 3 meters, if I remember correctly… but when I looked it up, it turned out to be 5 meters. I really tend to forget things these days. Design and construction of ground anchor works…
Going on an Overseas Business Trip as a Slope Engineer: Part 7 (Africa Edition)
Hey everyone! It’s Enta. I’ve heard it’s been extremely cold in Japan and that things have been pretty tough. Meanwhile, over here in Africa, it’s hot as hell! Young people are out on the beach flying kites. It looks like fun, but since injuries take a long time to heal for an old guy like me, I’m just walking along the beach instead. …
Going on an Overseas Business Trip as a Slope Engineer: Part 1 (Africa Edition)
Hi everyone, it’s Enta here. Actually, I’ve been in Mombasa, Kenya, for the past few days. Huh? Right? lol. To put it simply, I’m here in Africa to conduct a slope survey. I’ll carry out the survey, write up a report, and design the project so it can be implemented locally. That’s the kind of work I do, lol. Slope work—and I’m actually being called out overseas for it…
The Era of Labor Shortages! Decide What to Cut Back on to Get By!
Hello, everyone. This is Enta. I held a briefing session on drain rock bolts last weekend, and personally, I’m just glad I was able to get it out there for now. To finish up one more perk for everyone who attended by the end of the month, I’ll be running around all over the place again this month, lol. It all comes down to the basics…

Hello, everyone. This is Enta. We’re holding an information session to recruit members for the Drainage Rock Bolt Method Research Group (tentative name)! Today’s session is all about the drainage rock bolt method!! We received applications from over 50 companies this time. We expect representatives from about 40 of those companies to attend. We regret to inform…
How do you verify the anchorage point in ground anchor construction?
Hello, everyone. This is Enta. In a recent survey conducted at the “K&i Web Academy,” I received a suggestion asking, “How can I check the anchorage of ground anchors (other than using slime)?” I’d like to write about this topic today. …
How to Calculate Cement Slurry and the Loss Rate
Hello, everyone. This is Enta. I used to have a grout calculation website, but I shut it down, so people still mention it to me from time to time lol. So, I’ll list the minimum necessary coefficients here. However, since that alone would make the calculation method a bit bland, I’ll include the full method as well. Borehole diameter (…
