Wouldn't an anchorage load of about 80–90% of the design load be appropriate for ground anchor construction?
Hello, everyone. This is Enta. The other day, I was talking with the president of a company, and he asked, “Do you know how to handle customers who want to leave early?” I learned this for the first time myself, but apparently, placing a broom upright at the front door is said to bring good fortune…
Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 5): Materials
Hello, everyone. This is Enta. I had intended to explain the basic test documentation first, but due to my schedule (I’m swamped with various things), I think I’ll start with the construction process instead lol. Basic Test (Part 1) for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction. In ground anchor construction…
Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 1)
Hello, everyone. This is Enta. I’ve been planning a basic test for ground anchor construction for the past few days. This is my first time dealing with this kind of case, so I can’t conduct the test using standard anchor materials... lol The reason is that, first of all, the embedment length of the anchors we’ll actually be using…
We conducted a basic test, but it wasn't very accurate.
Hello, everyone. This is Enta. I took the basic exam the other day. What exactly is the basic exam? (In a nutshell) Since the pressure gauge on the manufacturer’s jack is analog, I’ve replaced it with a digital one. The reason I switched to digital is that, no matter who’s reading it…
Here's how to take the basic exam for rebar installers.
Hello, everyone. This is Enta. Have any of you ever taken the basic exam for rebar insertion workers? It’s pretty common for ground anchor workers, isn’t it? But there aren’t many exams for rebar insertion workers. Basically, they’re the same, but since there’s no free length, that’s where the ground…
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…
Civil Engineering Construction Management Standards: March Reiwa 3 Addendum | Knowledge
Hello, everyone. This is Enta. Did you all know this? I actually went to a job site the other day and was told that rebar insertion work has been added to the Ministry of Land, Infrastructure, Transport and Tourism’s Civil Engineering Construction Management Standards—specifically, the quality control standards and specification values from March Reiwa 3. Last year, in March Reiwa 2, “medium-layer mixed treatment” was the most…
I Tried Making an Assembly Support Plate (Part 1) | DIY
Hello, everyone. This is Enta. When conducting basic tests for ground anchor construction, you need a load-bearing plate, right? For example, something like this. Steel load-bearing plates typically weigh between 200 kg and 600 kg, don’t they? As for lightweight load-bearing plates, maybe something like an FFU weighing around 200 kg?…
What to Do When a Ground Anchor Comes Loose (Part 2)
Hello, everyone. This is Enta. I’d like to write about what to do when a ground anchor comes loose, as happened the other day. No one ever teaches you how to handle a loose ground anchor—it’s something you learn only through experience. Basically, ground anchors are a critical structural component…
