<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
We've been working on a new construction project recently.<\/p>\n
That said, it's just draining water\u2014but it's draining water in a tight space.<\/p>\n
<\/p>\n
Well, we're already removing the core, but we'll drill through the concrete surface and continue drilling even deeper.<\/p>\n
The machine is used exclusively for core drilling.<\/p>\n
In Tokyo and Yokohama, they use core drills to drill holes for rock bolts, so this is an application of that technique.<\/p>\n
<\/p>\n
I think this is probably the first time this machine has been used for dewatering in the Tokai region. (Maybe it\u2019s not very common nationwide either?)<\/p>\n
And I'm sure you think it looks easy (in the photo), right?<\/p>\n
This is super hard lol<\/p>\n
I think it's okay to try it if you have the equipment, but if you don't know the trick, it'll turn into a total disaster lol.<\/p>\n
<\/p>\n
Since you\u2019ll eventually have to drill through bedrock, wouldn\u2019t it be pretty tough without at least some knowledge of drilling?<\/p>\n

It's full of rocks like these.<\/p>\n
I'm working on this area right now\u2014it's at the peak of the chart, so it's really tough, lol.<\/p>\n
The bits will fall apart.<\/p>\n

<\/p>\n
All the chips have flown away.<\/p>\n
Bitcoins costing 30,000 or more each\u2014and look at the state they're in...<\/p>\n

<\/p>\n
Even the core tube has gotten thinner, and look what's happened lol<\/p>\n
What's more, this borehole is only 6 meters deep.<\/p>\n
When it gets this bad, I really have no choice but to replace it\u2014it\u2019d be dangerous not to\u2014but it\u2019s a pretty grueling battle.<\/p>\n
<\/p>\n
That said, I\u2019ve been getting used to the mountains little by little, so I think things will gradually get better.<\/p>\n
Specialized construction work is all about know-how and expertise, so I\u2019ll keep building up my skills little by little.<\/p>\n
I imagine we'll see more projects like this in the future, so it would be interesting if we got a request.<\/p>\n
Although this is our first construction project, the government has approved the budget, so it looks like we\u2019ll be able to establish a baseline for future costs.<\/p>\n
It's mentally important to do it first, lol.<\/p>\n
I'm pretty sure we're number one in the Tokai region, lol (not that it matters, though lol).<\/p>\n
<\/p>\n
See you later.<\/p>","protected":false},"excerpt":{"rendered":"
