The Order in Which the Head Treatment Fails in Rebar Insertion Work
Hello, everyone. This is Enta. The other day, I received a really interesting and great photo on X. This is the one. It’s a photo of rebar insertion work that was done quite a while ago. I imagine that when it was first installed, the base was neatly constructed and it looked like it fit perfectly…
When preparing the ends of rebar inserts, is it better not to tighten the nuts?
Hello, everyone. This is Enta. I’m sometimes asked, “How much torque do you apply when tightening rebar inserts?” What are your thoughts on this? Basically, you just tighten them enough so they don’t come loose, but occasionally some people say you should use a specific load controlled by torque…
Since we have historical data, I think both the design and construction could be simplified even further.
Hello, everyone. It’s Enta here. Check out this ground anchor. It’s got a real vintage vibe, doesn’t it? lol But this anchor is still going strong! It’s still holding up even after getting beaten up by a backhoe. lol Apparently, it’s been in the ground for about two years now, but this is the one…
Here's the pressure used for pressurizing packers in ground anchor and rebar insertion work!
Hello, everyone. This is Enta. I’m sure you’ve all used a packer before. If you haven’t used one before, check out “How to Make a Packer for Ground Anchor Work (Part 1),” “How to Make a Packer for Ground Anchor Work (Part 2),” and “Ground Anchor…”
When calculating the number of scaffolding workers at heights, the count starts from the bottom and works its way up!
Hello, everyone. This is Enta. Today, I’d like to talk about billing for scaffolding work. Scaffolding is often required when ground anchors or rebar inserts are installed at the top of a slope, isn’t it? For example, suppose there were ground anchors or rebar inserts in a location like the one shown below…
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 (…
The materials used in rebar insertion work should be as simple as possible!
Hello, everyone. This is Enta. When you’re installing rebar, are you sure the lengths are correct? You might be thinking, “Huh?”—but what I’m asking is, how do you determine the lengths during the design phase? This is mainly for design consultants, but let’s say the design calls for 5-meter-long rebar…
The jig used by rebar installers to center the rebar is called a clip spacer!
Hello, everyone. This is Enta. I’ve mentioned this a few times on this blog. It’s a jig used by rebar installers to position the rebar in the hole. The photo above shows the jig securely holding the rebar in place. While this has become pretty standard practice these days, there are still some people who aren’t familiar with it…
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…
