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…
Basic Structure and Principles of Ground Anchor Systems — What Exactly Are Ground Anchor Systems? —
Hello, everyone. This is Enta. I’d like to give a brief explanation of ground anchor construction. ~The invisible force that stabilizes the ground through tensile force~ Ground anchor construction is a method that stabilizes and secures the ground or structures using a “pulling force” (tensile force). Slope failures and retaining walls…
What exactly is the Basic Exam? (In simple terms)
Hello, everyone. This is Enta. I’ve been conducting preliminary tests at a job site for the past few days. Have you ever done a preliminary test for ground anchor work? When performing this kind of ground anchor work, the key factor is the anchorage layer. This preliminary test is designed to verify that…
What to Do When a Ground Anchor Comes Loose (Part 3)
Hello, everyone. This is Enta. In this post, I’ll explain what to do if a ground anchor comes loose during tension work. Let’s say a ground anchor comes loose during tension work. Technically speaking, this is referred to as “adhesion failure.” Depending on which part of the anchor has lost its adhesion…
Extremely Rare!! The Moment a Ground Anchor Worker Slipped!
Hello, everyone. This is Enta. Today, I’m finally releasing the video I mentioned earlier—the tensile test on ground anchors—showing the exact moment the anchor pulls out. Please take a look. It made a “pop” sound at the end and came out. This type of pull-out involves cement slurry and PC steel…
