Distinguishing Between Rebar Insertion and Ground Anchor Work
Hello, everyone. This is Enta. Lately, there have been a lot of rebar insertion jobs. A contractor told me, “There sure aren’t many ground anchor projects these days, are there?” Well, the fact that there aren’t any ground anchor projects probably means they aren’t anticipating significant slippage and don’t want to spend that much money…
Dredging with a Suspended Drilling Rig
I’ve added a banner at the top of the site. Please be sure to join us. Participants: Currently 15 people. Hello, everyone. This is Enta. It’s March—the last month of fiscal year 2022! Let’s do our best to avoid any accidents! We’re currently working on a site where the clay is too hard to drill with a suspended drilling rig…
In rebar installation work, simply removing that material is sure to improve quality!
Hello, everyone. This is Enta. The other day, I was working on a job site installing rebar inserts, and they actually removed that material for me! This is it! This material in the black part!! And the cap at the tip!! I managed to get the sheath tube and tip cap removed from the design lol. This...
About Nominal Diameter | The Difference Between a 90 Drilled Diameter and Actual Dimensions, and Cement Calculations
Hello, everyone. This is Enta. The other day, Ishio-kun, a construction-themed YouTuber, came to visit our company! We went together to tour a construction site where Enta is the primary contractor for Ishio-kun’s construction channel, and he interviewed us about all sorts of things lol. The general contractor also kindly gave us permission to mention their name…
As a rebar installer, I tried using a new grout material that’s different from cement slurry for the first time!
Hello, everyone. This is Enta. I did my first construction job the other day. I can’t go into too much detail, but it was the NATM method, lol. You know, the one they often use for tunnels and such. The injection pressure was around 2 MPa, and it took about a minute for the material to set (gel time). (…
Tips for When Rebar Just Won't Go In During Rebar Installation
Hello, everyone. It’s Enta here. I turned 47 today, lol. When I was younger, I thought I’d be a total old man by the time I was 47. But it turns out that even though I look like an old guy on the outside, I’m not really that old on the inside, lol. Anyway, moving on—single-pass drilling methods like suspended drilling…
Is the reason torque wrench management never goes away because nuts come loose?
Hello, everyone. This is Enta. The other day, late in the afternoon, I got an email like this from a Nepalese technical intern—it had me laughing so hard lol. I’d like to teach him a thing or two about Japan next time ^^ The other day, I went to a job site where rebar was being installed using a torque wrench. It’s about time this completely…
Should the Injection Hose Be Removed When Inserting Rebar? | The True Meaning of Foreign Matter Contamination
Hello, everyone. This is Enta. When it comes to rebar insertion work, quite a few people say that the grout hose tends to come loose. Do you know why that happens? The people who say that are mostly laypeople who’ve outsourced construction management—lol. I don’t think many site supervisors say that. (Though there are a few, of course.) &nbs…
We strongly recommend conducting tests to measure circumferential friction resistance before starting this project!
Hello, everyone. This is Enta. The other day, we conducted a basic test for rebar insertion workers. This test checks whether the designed circumferential friction can be achieved, and since the formwork has already been installed, the test is being conducted within the formwork. Well, that’s just the way it is, so we’ll go ahead with the test…
