Hello, everyone
This is Enta.
February is coming to an end this week, isn't it?
Just like last year, March is here before we know it.
It’s the end of fiscal year 2,016.
Stay focusedLet's just make sure we finish the job safely!
But that's beside the point.
Have you heard of capillary action?
That's the point.
This videois very easy to understand.
This phenomenon is commonly observed on slopes.
After drilling for rock bolts or anchors,
Water is still coming out even though we're injecting grout.
The cause is capillary action.
There is a water hose running underneath the PC steel strands shown in this photo.
This is because water is still flowing uncontrollably even after the concrete has been poured, so
"Ho" is being accepted.
This is,The areas where the grout adheres to the surrounding rock after injection
The surface tension of the spring water and the surface tension of the grout, and
It rises due to capillary action. (It is drawn up.)
People often tell me to stop doing this, but,
I can't stop.
From a mountain perspective, it's better to let it flow than to stop it
It is safe because it remains in an unsaturated state.
If the volume seems excessive, connect a hose, and
It looks better if you treat the wastewater.
See you later.
