Should the Injection Hose Be Removed? | 2018 Guidelines

Hello, everyone.

This is Enta.

The thermometer at the site read 40 degrees...

It's already hell.

Please be very careful not to collapse!


But that's beside the point.

In rebar insertion work,The injection hose has come looseQuite a few people say that.

Do you know why?

The people who say that are usually amateurs who’ve outsourced construction management, lol.

I don't think there are many directors. (Though there are a few, of course.)

 

When you ask why, they say it’s because the material is different from the rebar, and that they won’t accept any foreign matter, right?

Well, well. Is that so?

When I ask, “So what happens with this?” they can’t answer.

First up is this one, which has become a familiar sight lately.

Grout Hose for Rebar Insertion WorkersThis is a conduit.

This is made of the same material as the injection hose, right? It's listed in the government agency's design specifications.

Can this injection hose really be considered a foreign object??

Since it's inorganic, it won't rot, right?

How about this next one?

KTB Anchor Load-Bearing Section, U-Turn Type

This is just a tentative assumption, but the free length of the anchor body is the same, right?

What do you think of the corrugated VSL anchor?

VSL Anchor

The whole thing is wrapped in corrugated cardboard, right?

Is this a foreign object?

Do you seriously think that the grout hose could have a negative impact on rebar insertion work??

In my personal interpretation, there is no need to remove it.

That's right. After all, even in the anchor installation work mentioned above, why would it be necessary to remove something that wasn't removed during that process during the rebar insertion work?

You're wondering if the conduit has any effect, right?

Besides, considering that polyethylene-based materials are already present in the concrete, I don't think that's a valid reason to remove them.

 

I'm not sure what aspects of construction management he focuses on, but,

There are a lot of weird people among construction management contractors, aren't there? lol

I don't mean to say anything bad about it.

The point is that if you're going to give instructions, you need a solid theory and a sound basis for them.

 

If that makes sense to you, we can accommodate it; if not, it just means we need to recognize that we haven’t studied the matter thoroughly enough.

That’s how I believe construction management should be.

Unreasonable

My former boss used to say, “Construction management really is an unreasonable job, isn’t it?” lol

I really do think so, lol

See you later.
