Reinforcement Installation Even in Tight or Quiet Spaces!
Hello, everyone. This is Enta. For the past few days, I’ve been teaching Vietnamese workers how to insert rebar using a core drill. It’s a masonry reinforcement project, but the stones on the surface are of such high quality that they’re incredibly hard! It’s granite that’s hard to crack even with a rock drill, but as expected, the diamond bit…
Surface Tension and Capillary Action
Hi everyone, it’s Enta. I’ve got a lot of business trips this week, lol. I’ll be in Tokyo on Thursday and Friday, so please take care of things while I’m away (what’s that supposed to mean, lol?). Anyway, have you heard of capillary action? It’s the “Capillary Action Wiki.” https://www.yout…
These Stone Walls Are Seriously Dangerous! Top 5!!
Hello, everyone. This is Enta. I’m swamped with planning for next week’s event, as well as my daily design and cost estimation work, lol. If I don’t keep finishing things up and sending out emails, the work just keeps piling up one after another… I’ll do my best, lol. Anyway, getting back to the topic at hand—I’ve been getting a lot of requests for stone masonry work again lately, but for now, how should I put it…
Methods and Principles for Measuring Drill Hole Length
Hello, everyone. This is Enta. Since quite a few people seem confused about the concept of drilling length, I’d like to explain it. Let’s start with the basics. Drilling length refers to the length of the drilled hole. So why is measuring drilling length so confusing? It’s because of the remaining length…
Slope Construction Problem 1 (Answers for Slope Framing and Rebar Insertion)
Hello, everyone. This is Enta. Slope Stabilization Problem 1 (Slope Retaining Structures and Rebar Insertion). Here are the answers to the previous Slope Stabilization Problem 1. Since a perfect-score answer was posted in the comments section the other day, I’ll just use that, but I’ll provide an explanation just in case. If an inspector were to ask, “Isn’t this part substandard?”…
Slope Construction Problem 1 (Slope Framing and Rebar Insertion)
Hello, everyone. This is Enta. Starting with this post, I’ve decided to launch a new series called “Slope Construction Problems.” In this series, I’ll be answering the various questions and inquiries I received during final inspections back when I was a construction supervisor. I hope you find it helpful ^^ Regarding the type of ground mentioned above…
For mountains where double-pipe drilling isn't possible and the borehole walls won't hold on their own, self-drilling is the only option—but this is the only way to eliminate all uncertainty!
Hello, everyone. This is Enta. I received a question on Twitter regarding my recent article. Since I think this is an area that design consultants and government officials might not be familiar with, I’d like to address it. When double-tube drilling isn’t an option and you have to use self-drilling rock bolts, how should you approach the design…
Found a great product! (Single bit for hanging-style use)
Hello, everyone. This is Enta. The other day, I got a message from someone in Shikoku asking, “What do you do when you can’t dig with a suspended core drill?” Without hesitation, I replied, “Dig with water!” lol. Digging with a suspended core drill using water—it gets the area around it really messy, but it gets the job done^^ What we’re after is the rebar…
Is paying close attention to the details (thoughtful workmanship) the key to survival as a contractor?
Hello, everyone. This is Enta. I’d like to talk about clip spacers, which we’ve been getting a lot of inquiries about lately from people in the construction industry. Since we designed them primarily for use in rebar insertion work, it seems they’re being used in ways we never expected. For example, it appears there aren’t any spacers available for cross-directional rebars…
