Hello, everyone.
This is Enta.
Where do you think the risks lie in ground anchor construction?
From a craftsman’s perspective, how should the work be done?
That's what it means, right?
However, installation is relatively simple.
I'll try writing this step by step, while including the management items as I go.
The blue section is under construction.
Management: Verification of Drilling Locations
Construction: Set up the machine at the drilling location and drill to the specified angle and depth.
Work Performed: Cleaning the interior of the outer casing (blasting from the bottom with air and water)
Work Performed: Inner Rod Retrieval
Control: Drilling Length, Drilling Angle, and Positioning Error Measurement
Drilling Angle Measurement
Positioning Error Measurement
Construction: Prepare cement slurry using the specified mix ratio
Management: Flow rate measurement, preparation of test specimens (mud balance, salt content measurement)
Construction: Insertion of anchor bodies (for immersion methods, grout is injected first)
Work Performed: Cement slurry injection (overflow check)
Work: Retrieve the outer casing (up to the set-in length)
Application Method: Pressure Injection (approx. 0.2 MPa)
Work Performed: Removal of All Outer Casing
Management: It’s fine to use “placement error” here, but since that might be confusing, please use a term that makes it easier for the administrator to explain.
Management: After verifying strength through compressive strength testing of test specimens, conduct validation tests and confirmation tests (multi-cycle and single-cycle).
Installation: Attach the jack to the anchor and apply tension.
Installation: After testing is complete, allow the material to set, then treat the ends.
Administration: Organizing exam data
So, that's basically how it goes!
It's easy, right? lol But then again, you won't know if it's easy until you try it!
I think that's pretty much how it is.
After all, there's nothing like actually doing the work yourself, so give it a try lol
And the biggest source of anxiety here is the exam.
And since this is a surprisingly important point, I'll save it for tomorrow.
See you later
