Donation of a Well for Disaster Preparedness and a Certificate of Appreciation
Hello, everyone. This is Enta. We’ve been completely thrown off track by the typhoon that’s been hitting us since last week… Work on site has come to a standstill for no good reason… But this rainy typhoon has left some serious damage in its wake. I hope none of your sites have been affected. Anyway, the other day, in 2024…
Drill holes directly into the zabuton frame
Hello, everyone. This is Enta. As I mentioned the other day, I went ahead and filmed a video showing how to cut the opening for the zabuton frame. Do you really need a cutout for the zabuton frame? Since there’s no rebar running through the center, it cuts out cleanly. Seeing this, I guess a cutout really isn’t necessary after all…
The site supervisor thinks he’s the cheapest (according to the God of Construction).
Is it free if the site supervisor does it himself? We hire a demolition contractor to do the demolition. And sometimes, we have a handyman clean up the mess afterward. The reason for this is that it’s more efficient. Site supervisors understand this, right? Asking the demolition contractor to help with the cleanup…
Post-processing of test specimens after preparation for the compressive strength test
Hello, everyone. This is Enta. Are you conducting compressive strength tests? Well, I’m sure you are, lol. I think most veterans already know this, but there are some preparations to make after coring. If you skip those steps, the strength may decrease or the test may fail to yield a valid result, so let’s go through the steps…
Rock-to-Rock Bonding Using Mouldam
Hello, everyone. This is Enta. There are various ways to handle loose rocks that are uncovered during rockfall and loose rock surveys, aren’t there? One of those methods is rock bonding. Well, generally speaking, only one company comes to mind, but actually, we do it too, lol. Or rather, we’re the ones doing it…
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 (…
Questions and Concerns Regarding Slope Stabilization and Anchor Work (Including an Apology)
Hello, everyone. This is Enta. I’ve discovered something that makes me feel really bad toward everyone who posted in the Q&A box. Here’s the Q&A box I set up here a while back. I’m really sorry to everyone who posted there. I didn’t even realize it until the other day! Once I realized it, I posted…
At construction sites, the WBGT index is like a "red light—cross with caution" sign.
Hello, everyone. This is Enta. It was hot the other day, but this week it’s been raining due to the typhoon. The stifling heat has eased up a bit, but since there are precautions to take against the typhoon, let’s be extra careful and do our best. Anyway, speaking of heatstroke prevention, Ishio-kun’s advice aligns with my own thoughts, so I wanted to share it with you all…
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…
