Hello, everyone.
This is Enta.
The other day, I went to check on the drainage work we installed last December.
Although the site was supposed to be dry during the construction period, there was actually a surprisingly small trickle of water coming out.
This construction site is inside a tunnel, and even though there are practically no mountains above us, the water is really bad lol.
The water comes out so strongly that it really seems like it’s being sucked up from below.
It's hard to tell from the video, but it was flowing at a rate of about 1 liter per minute.
Well, with all this heavy rain, it looks like the mountains are holding quite a bit of water.

Water is still seeping out of this tunnel, so alternative measures are being sought.
Ideally, we’d like to completely close the tunnel to traffic so we can thoroughly drain the water, but unfortunately, we can’t close it.
Well, since we’re doing our absolute best with just one side, we can only drain 3 meters, after all.
Plus, it was super hard (the rock), so drilling was a real struggle lol

I'm still thinking about what to do next, lol.
The challenge is how to supply water, collect it, and drain it, isn't it?
See you later.
