Hello, everyone.
This is Enta.
Last time, we got up to injecting the void.
Below is a picture of the painting after the injection was completed.
Let's assume that this fills the gap.
The important step from here is to drill a hole in the drain pipe.
Drill new holes in the countless drain pipes to drain the water from inside.
There's a possibility that the injection material is clogged, so be sure to
It's a hammer drill, so it's for drilling!
Ideally, you should always use an anti-suck-back agent when spraying on soil and sand surfaces!
Insert a fiber material, such as Stella Sheet, behind the drain pipe.
Doing so will prevent the soil inside from washing away.

Well, this was before the mortar was sprayed on, wasn't it?
Alternatively, you could install a 10 cm × 10 cm Stella sheet behind the drainage pipe, as shown here.
If you absolutely cannot attach it to the existing mortar, roll up the Stella Sheet tightly, and
There's nothing to do but stick it into the drain pipe.
Still, it's better than nothing.
When doing so, please apply weather-resistant caulk to the surface so that the Stella Sheet adheres to the drain pipe.
If you do that, I don't think the Stella Sheet and the drain pipe (PVC pipe) will become stuck together and come out.
You don't need to caulk the middle section; it's fine as is.
