Hello, everyone.

This is Enta.

The other day, for the first time in a while,Verification of the Number of Anchors InstalledI went there!

It's the final inspection, isn't it? (laughs)

Of course, the focus is on on-site supervision, but we’ll also discuss various issues at the job site.

Of course, I’m talking about ways to increase the contract amount, lol (though only for the parts I think are necessary).

 

This site features a permeable retaining wall—a rarity these days—with neither drainage pipes nor a concrete drainage layer.

There used to be quite a few of the "infusion" type a long time ago, but these days they're practically nonexistent.

It seems the rainwater is meant to seep into the natural ground behind the retaining wall, so there is no PVC pipe installed at the center of the retaining wall’s side beams, and

It's a legal framework that doesn't even allow for permeable concrete.

That was also the case with the existing legal framework.

I'm told the existing structure was built about 20 years ago.

Some of them were secured with sandbags filled with soil and appeared to be relatively new.

It seems that the natural ground, which had become saturated with rainwater, partially collapsed, and they later stabilized it with sandbags filled with vegetation.

The vertical frame of the formwork was partially raised, and sandbags had been stacked there.

Depending on the soil conditions, it can be difficult to allow water to seep in and then contain it with a retaining wall.

After all, permeable concrete is the easiest to understand and offers the best workability, isn't it?

On the other hand, the reason why drain pipes fail is that over time, holes in the PVC pipes get clogged (with things like fallen leaves).

If it becomes clogged, water will accumulate. If water accumulates, the vegetation will rot. There is a risk that it will die.

And once it permeates, it reaches a state of saturation, and pressure begins to build from within the legal framework.

What happens to legal frameworks that have become outdated due to the passage of time?These days, it's all about the ever-rising life cycle costs.That's it.

And that’s how holes are drilled into small-cross-section concrete structures measuring just 200 mm or 300 mm.

I can't help but wonder, "How strong is it, really?" Though, to be honest, it's actually a bit overkill, lol.

Basically, it’s better for the slope to be dry, and the underlying soil should be loose.

If you just say something like, “We’d like to discuss the results above, so thank you for your cooperation,” that usually works out fine lol.

Since this varies by region, I can’t say for certain, but it is an issue that’s often raised in audits.

If you search online, you'll find past examples of accounting audits.

 

Speaking of costs, when using in-frame planting, the area covered by the drainage concrete is reduced.

There was a decrease in vegetation within the frames and an increase in concrete drainage, but the results showed no significant difference.

Government agencies are also more receptive to it.

Another aspect of the proposal that the government is likely to accept is the maintenance and management component.

For example, along national highways, they take measures to keep the grass from growing, right?

It's partly for disaster prevention, but mainly because we can't maintain it anymore. We just don't have the time or the people to mow the grass anymore.

If I say something like, “Should we spray some mortar here—in places where the grass is growing out of control?”

Government agencies will also find it easy to get on board.

Obviously, I won't be doing this out of the goodness of my heart, lol—but I'll do it if I get paid properly.

We’ll also need to check our financial status with the government office, right? How are we doing in terms of the balance? And as for other on-site matters...

In the end, it all came down to the admin's way with words lol

 

See you later.

*I took some photos of the packer! I didn't forget, lol.

And finally, everyone’s back at the office! These past three weeks have been tough~

We're going to go all out from here on out!! Stay safe!!
