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 Tried Measuring the Limit of Packer Pressure!
Hello, everyone. This is Enta. I actually conducted this packer experiment a long time ago, but I finally got around to editing the video... I cured the material under 0.2 MPa pressure, at maximum pressure, and without pressure to observe how much it expanded. However, I later realized that this experiment was pretty much pointless...
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…
We invited the Public Works Research Institute to conduct a site tour!
Hello, everyone. This is Enta. The other day, with the cooperation of the general contractor, we held a site tour for representatives from the Public Works Research Institute at a project Enta is working on. You’re probably thinking, “What on earth is that?!” lol National Research and Development Agency, Public Works Research Institute 🏗 National Research…
Guidelines for Diluting Cement Slurry with Hot Water Based on Finished Mix Temperature
Hello, everyone. This is Enta. I received an email regarding the discussion we had the other day about mixing mortar with hot water. The question was, “What about grout?” Based on my experience, I think using cement milk is a viable option—especially when working in extremely cold conditions. I ran a simulation using mixing water at 50°C. Simulation…
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…
