Hello, everyone.
This is Enta.
Are there any criteria for deciding whether to perform a test spray?
Since material was wearing away too quickly at this site, we applied a temporary spray coat first, followed by the final spray coat.
When the ground conditions are poor
No matter how hard I try to stack the bricks, they just keep falling apart.
There are frequent rockfalls.
The slope is steep and slightly overhanging
You can still get scrapes even from a light, misty rain.
Excessive excavation during drilling (when correcting with sprayed concrete)
Is this what you had in mind?
In situations like this, we perform a test spray. (Test spraying)
By doing so,Safe ConstructionNot only is it possible, but it also makes installation easier.
Rockfalls are particularly dangerous, so I recommend using a temporary blast.
After planing the wood, I'll nail down the lath, but,
A common question that comes up at this point is, “Aren’t the ‘temporary blow’ and the ‘final blow’ separate?”
That's certainly possible, but it's not a problem.
That's because mortar is sprayed to smooth out unevenness on slopes.
Since that mortar will be located beneath the designed structure, it is considered part of the natural ground.
Temporary blasting is considered part of the natural ground.That's the way it is.
That means it doesn't need to be that strong, so even a low-strength mix is acceptable.
Well, if the quantity is small, I guess I'd just use the standard mix.
As long as the strength is equal to or greater than that of the natural ground, there is no problem.
It amounts to a "throwaway" mindset.
When the natural ground is unstable, install temporary shoring to ensure safe construction.
It’s also possible to bring the matter up for discussion at the local government office and have them review the design, so in some cases, having them review it might save you from having to come up with those “magic words” or get creative lol.
See you later.
