Hello, everyone.

This is Enta.

The recent heavy rains have caused damage in my neighborhood as well.

After all, we really are powerless in the face of nature.

We are overwhelmed by this overwhelming power.

I heard that the machinery was swept away along with the newly constructed retaining wall.

I’d especially like those involved in river construction projects to keep this in mind: it’s better to remove any materials that have been brought up from the river.

This is an absolute must. Especially when it comes to machines.

I, too, had once thought during a river construction project, “The water probably won’t reach this far,” but then the river swelled due to a dam release, and 10 casings (φ135) and

We offered the pressure washer to the river.

The river eventually subsided.

 

But this rainy season has been incredibly rainy!

The mountain is already at capacity.

Please assume that the situation is such that it could collapse at any moment.

If you are currently working on the slope, I think it would be best to suspend work for the time being, if possible.

Are there any abnormalities on the mountain?

Are there any vertical cracks in the sprayed mortar?

Vertical cracks are spreading! There may be soil pressure building up.

 

Have you noticed any cloudy water coming out of the faucet for the past few days?

The mountain is barely holding up, but it may explode (collapse) at any moment.

 

With all this rain day after day, it wouldn’t be surprising if some slope were to show signs of instability.

It makes me wonder if we should take a little break from the slope work.

In reality, the general contractor’s supervisor’s judgment takes precedence, but I’d like the foreman to thoroughly inspect the site and make his own judgment as well.

 

By the way, even at sites where landslide inclinometers have been installed, you shouldn’t let your guard down.

Inclinometers cannot keep up with the speed of small slope failures.

The inclinometer is designed for large-scale landslides, so it cannot be used for small-scale landslides.

Just because the inclinometer isn't moving doesn't mean everything is okay, so please be careful.

The same applies to the extensometer.

 

Please continue to be very careful for about another week.

Even after the rain stops, it will take several days for the mountain to stabilize.

In any case, please exercise the utmost caution and ensure everyone's safety.

 

See you later.
