Hello, everyone.
This is Enta.
The other day, I had a drinking party with the Chamber of Commerce and Industry, so I couldn't write a blog post, and this morning I had to be on site first thing, so it's taken me until now to get around to it.
I usually make it a point to write my posts the day before and upload them at 8:00 a.m., but every now and then, things like this happen...
Well, I'm still writing every day, so please bear with me on the ending, lol.
But that's beside the point.
Construction Methods for Ground Anchor Work
Ground Anchor Installation (Part 2)
We left off halfway through last time, so now that the scaffolding is set up, we’ll start from Step 4 of the machine setup.
4. Horizontal direction (straight and perpendicular to the section under consideration)
The direction of drilling is very important!
When designing an anchor, the first step is to determine the direction of installation.
Under normal circumstances,Main Measurement Line Directionor something like thatDirection of the Analysis Cross-SectionIt will be straight.
In some cases, the angle may be offset horizontally.
Please make sure to manage this angle carefully.
However,The Ministry of Land, Infrastructure, Transport and Tourism's management standards do not include the horizontal angle (horizontal opening angle).
As far as I know, the only standard that governs this angle is “Shizuoka Prefecture"That's all."
As with the standard for vertical angle, it is set at ±2.5 degrees.
In other prefectures, I’ve included this in our self-management system to improve concrete placement accuracy, soCreativity and IngenuityIt is sometimes listed as such.
As long as this angle is maintained properly, the ground anchor can be anchored at its designed location and within the intended anchorage layer.
See you later.
