Hello, everyone.
This is Enta.
When Installing Rebar, Should It Be Perpendicular to the Slope or at a Specified Angle!? (Part 1)
This is a continuation of the previous post.
When drilling at an angle perpendicular to the slope on highly undulating natural ground, the drill hole may intersect the slope.
Even if they intersect vertically, as long as their directions differ even slightly horizontally, they will not intersect, but
It's usually pretty accurate lol
In that case, consider the vertical and horizontal axes and adjust the angle of that specific part slightly,
The standard method is to adjust the drilling angle so that it does not hit the target.
Sometimes I'll check with the local government office, then check with the design consultant, only to get a "NO" in response lol
The reason for this "no" answer is the concern that the insertion length might not be sufficient for the planned immovable soil block.
However, in reality, the so-called "solid block of earth" is merely a hypothetical concept, and
There’s no way to tell where the solid clump of soil ends and the loose clump begins, and
It's nothing more than a theoretical exercise.
However, since this is also part of the design philosophy, we can’t go against it, so the answer is “no.”
*Since this is based solely on drilling data, I suppose it can't be helped.
The drilling angle perpendicular to the slope is the slope angle (at the intersection of the slope frame) minus 90 degrees, which is
The drilling angle is perpendicular to the slope.
The way people measure the angle at the intersection of the legal framework can easily vary by a degree or two, lol.
Around here,Install with proper alignmentLet's get started.
On the other hand, design consultants would just be at a loss if they heard something like that, lol.
To be honest, what matters is whether the specified number of bars has been placed in the design cross-section as planned, and
The angle isn't that big of a deal... (though it is important, lol)
Regarding the shape of the slope and the setting of the drilling angle,
Since machine selection is also a factor, I think we can probably put this into a table.
I'll think about that next time.
See you later
