What is the pressure condition at the fixation site during injection? (Is pressurization necessary?)
Hello, everyone. This is Enta. Since my last post, I’ve been writing about packer pressure. I Tried Measuring the Limit of Packer Pressure! I Tried Measuring the Limit of Packer Pressure! (Part 2) I Tried Measuring the Limit of Packer Pressure! (Part 3) Packer pressure…
I Tried Measuring the Limits of Packer Pressurization! (Part 5) Simulator
Hello, everyone. This is Enta. I tried measuring the limit of packer pressure! I tried measuring the limit of packer pressure! (Part 2) I tried measuring the limit of packer pressure! (Part 3) I tried measuring the limit of packer pressure! (Part 4) Continuing from last time…
I Tried Measuring the Limits of Packer Pressurization! (Part 4)
Hello, everyone. This is Enta. This is a continuation of my previous post. I Tried Measuring the Limit of Packer Pressure! I Tried Measuring the Limit of Packer Pressure! (Part 2) I Tried Measuring the Limit of Packer Pressure! (Part 3) Injecting while watching the gauge. What’s happening with the packer? …
I Tried Measuring the Limits of Packer Pressurization! (Part 3)
Hello, everyone. This is Enta. I tried measuring the pressure limit of a packer! I tried measuring the pressure limit of a packer! (Part 2) Last time, I wrote that you absolutely must not apply more than 0.5 MPa to a packer. The hose will burst, and the packer’s mesh will stretch, causing…
Installation of a Retaining Wall with Ground Anchors (Part 2)
Hello, everyone. This is Enta. Installing Formwork with Ground Anchors (Part 1) This is a continuation of the previous post. I think I mentioned in the last post to pay close attention to the angles of the anchors and the formwork! The next issue that arises with those angles is the rebar. The white lines on the formwork…
Installation of a Retaining Wall with Ground Anchors (Part 1)
Hello, everyone. This is Enta. Today, I’d like to talk about installing retaining walls. Let’s say we have a slope like this (in a design cross-section). There’s a design drawing showing the installation of a retaining wall. Let’s assume the design looks something like this (for illustrative purposes). Ground anchors have also been installed. …
Application of Anti-Rust Oil to the Heads of Ground Anchors
Hello, everyone. This is Enta. The other day, we invited someone from the Public Works Research Institute to help us manage our nerves. The most important thing when it comes to nerves is, of course, not to lose your cool (lol). That’s the top priority. To be honest, personally, I don’t even care about management data or anything like that…
I came up with some criteria for leveling uneven pressure plates!
Hello, everyone. This is Enta. The other day, I wrote a post on this blog about the contact area on the underside of load-bearing plates in ground anchor construction, but this time I’d like to address the question, “Is it necessary to level the underside of the load-bearing plate?” I get asked this quite often. Especially from construction consultants…
Permissible Range for the Contact Area on the Back of the Load-Bearing Plate in Ground Anchor Construction
Hello, everyone. This is Enta. The other day, a craftsman I know asked me, “How much unevenness on the back of a bearing plate is acceptable?” Man, this is definitely the part that gives us the most headaches on the job site, lol. Calculating the Area of a Bearing Plate A bearing plate transfers the force from the anchor to the ground…
