Hello, everyone.
This is Enta.
The office is absolutely packed with machines—it’s a total mess...
It looks like it's going to take some time to clean up and get everything in order...
But that's beside the point.
Once again,The Crack SeriesThat's it.
Up until the last time,
1. Spraying during periods of extremely high temperatures
2. The rock lines in the rock section and the sedimentary section were clearly visible.
3. Overhang (a section of a rock face where the slope extends over your head like a roof overhang.)
4. There was some spray loss.
5. Plastic spacers.
6. A pile of material slid down while we were spraying.
7. Nighttime temperatures drop to near 0 degrees (or below freezing).
8. The sand is bad.
3. Overhang (a section of a rock face where the slope extends over your head like a roof overhang.)
I think situations like this come up quite often, but as a general rule of thumb, “Eliminate any unstable parts.」
With this in mind, first trim the overhang until it forms a right angle.
I think doing that will almost completely prevent cracks.
If possible, it would be even better if there were a slight slope.
When it comes to cracks in overhangs, they tend to beTare CrackI think there are many.
After spraying, it’s as if the weight of the concrete is pulling it downward,
Cracks may form, and in the worst case, the thickness may be insufficient (although there are also specifications that allow for a negative tolerance).
Since this situation can generally be adequately addressed and prevented by cleaning the slope, I believe you’ll be fine as long as you follow the basic guidelines.
If it really isn't possible, let the mesh hang down by the thickness of the material and layer it about three times,
Spraying it on can prevent dripping and help ensure the desired thickness, but I wouldn't recommend it lol.
It is possible to use a repair net for the frame, but since that’s essentially like putting a weight on your head, I can’t recommend it.
Please cut it down as much as possible lol
The basic rule is to eliminate overhangs.
See you later.
