- Ground Anchor Construction
I attended the VSL Anchor Association's general meeting!
Hello, everyone. It’s Enta here. There’s no work, huh? lol First of all, we’re not getting any orders. It’s so slow, you’d think this year is “hell for construction companies.” The only region that seems to have work is Hokuriku, I guess. So, until just the other day, I was traveling all over Hokuriku. If things keep going like this, my sales efforts will just…
Considering Methods for Unloading in Ground Anchor Construction
Hello, everyone. This is Enta. The other day, someone asked me about methods for relieving load in ground anchor construction. I think there are various ways to do this. Basically, it’s quite difficult once the anchor is fully set and the excess tension length has been cut, but if there’s still some left…
Tips for Installing Compression Plates in Ground Anchor Construction (Part 2)
Hello, everyone. This is Enta. Following up on my previous post, I’d like to write about measures to prevent load-bearing plates from shifting. Tips for Installing Load-Bearing Plates in Ground Anchor Construction (Part 1) They shift like this (lol). Even a shift of just 1 or 2 cm stands out when you’re on site. Especially during inspections…
Tips for Installing Compression Plates in Ground Anchor Construction (Part 1)
Hello, everyone. This is Enta. Are you installing load-bearing plates? lol Well, if the design calls for it, then of course you’ll install them, but there are some tricks to installing load-bearing plates, right? The trick to installing load-bearing plates is figuring out how to install them without shifting their position, right⁉ That’s what it’s all about. &nbs…
During inner drilling, the borehole wall becomes temporarily self-supporting.
Hello, everyone. This is Enta. It looks like we’re about to enter the rainy season. This year, it’s been insanely hot even before the rainy season started, and it’s been raining like crazy. Let’s be extra careful with the rain this year! But anyway… When drilling with a double-bore method, the hole remains stable on its own. With a single-bore method, it’s really hard to…
Determining the Placement Location for Ground Anchor Installation
Hello, everyone. This is Enta. How do you go about positioning ground anchors during installation? I get asked about this quite often, so I thought I’d write about it this time. The drawings are actually quite vague on this point. That said, when it comes to the design cross-section…
Important Considerations When Selecting a Zabuton Frame
Hello, everyone. This is Enta. Did you know there are some spots where installing zabuton frames can be risky? The primary function of a zabuton frame is to level out uneven ground, right? They’re used to level the ground when installing load-bearing plates because the unevenness of the natural ground can’t be corrected otherwise.  …
A Battle Between Nature and the Slope-Construction Company?
Hello, everyone. This is Enta. Here’s a photo of a collapse at a rebar insertion work site. The mortar has come loose, and the rebar insertion work is being pulled downward. The design anticipated a surface collapse and called for a combination of mortar and rebar insertion work. The collapse occurred deeper within the structure. It collapsed after it rained…
Sequence for Installing and Removing Temporary Ground Anchors
Hello, everyone. This is Enta. What happens after temporary anchors are installed? Well, since they’re temporary, they’re removed once the permanent construction work is complete. They’re removed in the reverse order of installation. In the photo, they were installed from the top down, the lower section was excavated, and temporary anchors were placed at the bottom…
