Why I Believe Drainage Boring Is Essential in Slope Stabilization Projects, Considering Earth Pressure
Hello, everyone. This is Enta. Are there any bamboo groves near your job site? Well, as slope stabilization contractors, we tend to work in areas with plenty of bamboo groves quite often, don’t we? For example, let’s say this bamboo grove slides, and we’ve already installed slope reinforcement frames and rebar. After the bamboo grove slides, the soil starts to rot…
I think it's about time the drilling angles for dewatering borehole construction were revised.
Hello, everyone. This is Enta. I think I’ve written quite a bit on my blog before about the angle used in dewatering boreholes. The design specifications state an angle of about 5 to 10 degrees. So, what’s the deal with this angle? How is the angle determined for dewatering boreholes? …
When you think about good companies and bad companies, you’ll discover something surprising.
Hello, everyone. This is Enta. Today, we’re holding an information session on recruiting members for the Drainage Rock Bolt Method Research Group (tentative name)! The deadline is today! Since this is the very first information session, we won’t be accepting applications after today! As I mentioned in my previous post, this is so we can offer early-bird benefits. …
Watching the video of the completed collection well will help you visualize it.
Hello, everyone. It’s Enta here. I just got sent the video from the other day of the collection well, so please take a look lol. What do you think? It’s got a nice vibe, doesn’t it? If this were a well that was 20 meters deep or something, it would’ve been a real pain, so I’m just glad it wasn’t lol. For those of you who’ve never built a collection well before…
I think a well casing is necessary at the collection well! (There are occasionally sites where one isn't installed.)
Hello, everyone. This is Enta. We’ve finished installing the casing on the collection well we were working on last month, and it’s now complete. I’m glad it turned out so clean and well-finished. As for the collection well work, since we can’t manufacture the liner plates in-house, we have to bring in another company. Regarding this…
Introducing the steel-cutting bits used in the catch basin construction project
Hello, everyone. This is Enta. Have you heard of steel-cutting bits? Well, I’ve mentioned them a few times on this blog, so I’m sure you’re familiar with them, but this time I’m talking about using a steel-cutting bit in a catch basin. What do you think? It cuts cleanly, doesn’t it? One…
The Thrill of Drainage Drilling
Hello, everyone. This is Enta. Drainage drilling is something the general public doesn’t often get to see. The same goes for collection wells, but I don’t think I’ve ever seen a slope stabilization contractor who doesn’t perform drainage drilling. The real thrill of performing drainage drilling is, of course, hitting the aquifer…
Considering Future Trends in the Industry Based on Catch Basin Construction Projects
Hello, everyone. This is Enta. Right after Golden Week, we’ll be starting work on a catch basin project in Tokyo. It’s been a while since we’ve worked on a catch basin! Even though we do a lot of landslide prevention work, we don’t actually do many catch basin projects. That’s because the contractor for this kind of work is pretty much always the same one, lol &…
Is there any literature that provides a basis for determining horizontal placement intervals in horizontal directional drilling?
Hello, everyone. This is Enta. How do you determine the horizontal spacing for horizontal boreholes during the design phase? I’m referring to the spacing when drilling within the boundaries of a retaining wall or similar structure. I don’t think there’s anything about this in the literature, is there? In the case of catch basins, it’s related to landslides…
