Ground Anchor Construction
How to Make a Packer (Part 6)

Hello, everyone.

This is Enta.

It seems that the other day, Wakazono Manufacturing held a sander blade cutting contest! lol

So, in the end, it turned out that "Kire-Nja" was number one lol

The value for money and cutting performance of the "Kire-Nja" might just be the best out there!

Please check out the blog.

It's pretty rare to get to test cutting blades, so it's kind of fun lol.

Please take a look at our test results as well for reference.

But that's beside the point.

How to Make a Packer (Part 6)

Span Seal Installation Status 3

We left off here last time.

Place the packer over this.

You can just put it on in the usual way, but,

It's best to place it over the Span Seal so that it covers it as evenly as possible.

Alternatively, you can insert a single piece of Spanceal at the tip, the same width as the packer.

Hose Clamp Tightness

Next, install the hose clamp and tighten it.

This part is easier than dealing with track numbers and such.

Installation of Hose Clamps

By pressing down firmly on the span seal like this, I believe it’s sealed tightly.

Actually, this is where leaks are most likely to occur. Even if you think you've secured it tightly, it can still leak...

On the other hand, if you tighten it too much, the injection hose may become constricted, preventing injection, so you need to be careful not to apply too much force.

Since I'm concerned, I've also secured both sides of the hose clamp firmly with cable ties (Insulock).

Finally, since the tabs on this metal fitting are dangerous (they could tear the packer), wrap them with vinyl tape.

Protected with packing tape

At this job site, the free-length section was also a packer, so it’s connected at both ends.

Next, wrap the tape around the packer.

This is to prevent the device from getting caught during insertion. Some people may feel it isn't necessary, but that's entirely up to the administrator's discretion.

Using Masking Tape

This masking tape is really handy.

That's because they're easy to cut and inexpensive.

In any case, it’s best to secure it with masking tape before inserting the anchor, and make sure it snaps off easily after injection!

Restraining the Packer with Masking Tape

This is how you can bundle the packers into a compact group.

This will make it easier to put in!

Since vinyl tape is hard to cut, I'm still a little uneasy about it, so I'm not sure.

Some managers feel that this isn't a problem, so it's up to the person on the ground to decide.

I've got some interesting experimental data, so I'll share it lol

Speaking of adhesive strength, masking tape has half the adhesive strength of vinyl tape, so

You can see that it comes off easily and tears apart.

There have long been instructions online on how to make a packer.

This is a PDF document from the Wedge-Type Anchor Method Research Association’s website. For your reference.

This concludes our series on how to make a packer.

I think there are all kinds of ideas and approaches. I think it’s fine for everyone to have their own way, but it’s also true that there’s a lot of variation.

I'd like to try standardizing the process so that making packers becomes easier and more reliable.

Quite a few of my senior managers think Packer isn't all that great.

That's because the manufacturing process isn't reliable, and leaks often occur.

There's definitely something going on! I'm sure of it.

I would like to resolve that going forward.

 

See you later.
