Why are the coordinates of anchor installation locations necessary during the design phase?
Hello, everyone. This is Enta. I heard that recently, a designer was asked to include the coordinates of anchor placement locations on drawings. Someone asked me, “Does this even make sense?” so I thought I’d write about it. Is it better to include coordinate values on slopes? It’s better to include coordinates…
People often question the necessity of placement tolerances during concrete placement, but there’s always only one answer!
Hello, everyone. This is Enta. I still get asked about alignment errors from time to time. The question you’re all probably wondering is: “Is there really a need to do this? Is there any point?” I really do get asked this a lot. The purpose of measuring alignment errors: Since these are errors in alignment, it’s about the initial installation…
Tips for Tensioning and Setting Ground Anchors (Angle Adjustment Base)
Hello, everyone. This is Enta. When installing ground anchors, have you ever noticed that the angle adjustment base or support plates shift slightly during tensioning and setting? It’s not such a big deal when the design load is low and the tensioning jack is light, but when the design load is high and the tensioning jack is heavy, it’s really…
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…
Is that really the right material to use for the filling?!
Hello, everyone. This is Enta. Today, I’m going to talk about this lol. “Huh? What???” You’re probably thinking that, right? Yes. It’s about filling in the gaps. Basically, when it comes to rebar insertion or ground anchor work, grouting is done only up to the horizontal level. Anything beyond that…
Approaches to Placing Ground Anchors on Undulating Slopes (Part 2)
Hello, everyone. This is Enta. It’s suddenly starting to feel like fall—it’s really nice, isn’t it! In an environment like this, work really goes smoothly, doesn’t it…? The sweltering heat really is a pain, after all. September is coming to an end, but let’s keep pushing forward! But enough of that—let’s talk about uneven slopes in ground anchor construction…
Approaches to Placing Ground Anchors on Undulating Slopes (Part 1)
Hello, everyone. This is Enta. How do you determine the spacing for the zabuton frames in ground anchor work? With that in mind, I’d like to go over the basics. Let’s say you have a slope like this. Install ground anchors here with a 2.5-meter spacing in both directions…
Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 4): Soil Bearing Capacity
Hello, everyone. This is Enta. The other day, my flip phone broke, so I got a new one, but my contact list got wiped out lol. Because of that, I lost almost all my phone numbers. If you need to call me, it would really help if you could tell me your company name and your name whenever possible…
Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 3): Soil Bearing Capacity
Hello, everyone. This is Enta. Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 1) Basic Tests for Measuring Circumferential Friction Resistance (τ) in Ground Anchor Construction (Part 2): Bearing Capacity Since the last post, we’ve been moving away from the topic of circumferential friction. This time…
