Hello, everyone.

This is Enta.

The other day, I was working on a job site installing rebar, and they actually pulled that material out for me!

This is it!

This material in this black part!!

And the cap on the tip!!

 

I managed to remove the sheath tube and tip cap from the design lol

Surprisingly, a lot of consultants don't actually leave this out.

 

The reason is that, apparently, removing this might cause some kind of malfunction, so it can't be removed.

Another reason is that manufacturers include them in their drawings simply because they appear in the company’s old drawings.

 

It’s fine to remove this, and having it in place actually hinders the adhesion of the rebar.

 

So, with that in mind, I’m posting the text with this part removed.

 

Since grout does not enter the interior of the end caps and sheaths, the rebar remains exposed.
In recent years, the importance of backfill treatment has been particularly emphasized in ground anchor construction.

Since rebar insertion is a similar type of restraint method, if we’re going to apply the same logic,
I believe the sheath should be removed and the void filled with mortar.

The "Manual for the Design and Construction of Retaining Structures for Attached Slopes" also refers to "stiff-mix mortar."
In addition, only the sheath and tip cap are protected against corrosion by plating.
Normally, this would provide dual corrosion protection consisting of cement slurry and plating.

As a result, omitting the tip cap and sheath actually improves quality, so
We will discuss the matter with the aim of preventing its installation.

We were able to resolve the issue with a memorandum of understanding like the one described above.

We've received approval from the construction consultant and the local government ^^

 

I'm planning to pull them out as much as possible from now on. (I've been doing it all along, but they finally pulled them out for me lol)

Just having this makes the installation a total disaster.

If this amount decreases, material costs will be reduced. (Contract work will decrease.)

However, when you consider the overall quality and other factors, it’s a minor issue.

 

Personally, I just want to say that things I don't need are unnecessary! And things I do need are necessary.

I firmly believe that the kind of thoughtless reasoning that says, “I’ll put it in just because it’s there,” is absolutely unacceptable.

However, the best part was that we were able to share this with everyone as an example of a tree that was successfully removed as part of the prefectural construction project.

Public works contractors have a duty to ensure that high-quality products are installed in public facilities!

Because it's a tax.

That’s exactly why we want to make sure we carefully distinguish between what’s necessary and what isn’t, right? ^^

 

See you later.
