How to Deal with a Mountain That Suffers Minor Landslides Every Time It Rains
Hello, everyone. This is Enta. Around this time of year, the rain causes landslides in the mountains every now and then, doesn’t it? Even temporary shotcrete can’t withstand the soil pressure coming from deeper down. The sections above that are still holding up because we’ve installed rock bolts there, though. What do you do in situations like this…
When connecting PVC pipes in drainage boring work, sockets are the strongest option!
Hello, everyone. This is Enta. As for recent trends in dewatering drilling, it’s becoming common not to cut threads. I’ve also heard that if you don’t cut threads, the drill bit won’t fit into a 90-diameter borehole. That’s because it’s difficult to insert the VP40 socket into such a borehole. (Due to rocks in the borehole, etc…
Tips for Preventing Collapse During De-watering Boring Operations
Hello, everyone. This is Enta. In dewatering drilling operations, after drilling the borehole, you insert a strainer pipe and then pull out the outer casing, right? At that point, the strainer pipe tends to fall along with the outer casing (a phenomenon where the inserted strainer pipe falls down together with the outer casing). What should you do in such a situation…
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…
Sometimes you can see just how effective rebar installation is when a mountain collapses! But I really hope it doesn't collapse, lol.
Hello, everyone. This is Enta. When you’re working on a construction site, it’s not uncommon for landslides to happen, right? At times like that, don’t you find yourself thinking, “Wow, rebar insertion really does make a difference”? lol This site is no exception—the rebar, the cement slurry, and the natural ground are all firmly bonded together!…
I think a well casing is necessary at the collection well! (There are occasionally sites where one isn't installed.)
皆さんこんにちは。 エンタです。 先月施工していた集水井の胴巻きも終わり完成しました。 非常に綺麗に良い感じで終われたので良かったです。 集水井工に関してはどうしてもラーナープレートを自社で出来ないので他社が入ります。 この辺…
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…
Here's How to Address Existing Retaining Walls (Stone Masonry, Cliffs, and Collapsed Slopes) in Residential Homes! (Part 2) (For the General Public)
Hello, everyone. This is Enta. Here’s the solution for repair work on existing retaining walls (stone walls, cliffs, and collapsed slopes) in residential homes! (Part 1) (For the general public) This is a continuation of my previous post. Today, I’ll be writing about what to do when a stone wall is bulging outward. If it’s bulging outward, that means the interior has already collapsed…
What is the concept of angle in dewatering drilling?
皆さんこんにちは。 エンタです。 先月私が削孔し、管理した水抜きボーリング工が完了したそうですｗ 最終の仕上がりが非常に良い感じで、綺麗ですよね！ 1本30m弱の削孔で、削孔角度が7度なんです。 私はいつも思うんですが、角度付…
