Hello, everyone.

This is Enta.

I take my hay fever medication every night.

I'm the type who drinks at night and sleeps it off, but doesn't drink during the day.

So, I've noticed recently that even when I'm taking my medication, at night—especially when I haven't been wearing a mask or anything during the day—

Even when I take my medicine, my nose gets stuffy in the middle of the night, making it hard to sleep.

It seems best to avoid inhaling pollen as much as possible during the day, too!

Please be careful, everyone.

But that's beside the point.

Have you ever had any problems with dewatering drilling?

Generally, failures in dewatering drilling operations include the pipe failing to enter the borehole or being pushed back by backflow.

Things like that, right?

Drilling for drainage seems like one of those construction projects that isn't actually that difficult.

All you have to do is drill a hole horizontally (even a novice can do this for a depth of about 10 meters) and insert a perforated pipe.

At first glance, it really is simple.

At first glance, though (lol)

ThisThe most challenging part of the construction method is almost entirely the drilling.That's it.

While digging downward is challenging in its own way, digging upward is more susceptible to the soil conditions, as the soil tends to exert pressure on the tool.

If it gets jammed, the machine will stop moving entirely.

Since the machine itself isn't operating at full power, it is possible to pull it out, but depending on the situation, we might have no choice but to leave the casing behind!

 

I’m also an anchor installer, but clay and silt soils really are a tough challenge.

That said, I feel reassured because the contractors who typically perform dewatering drilling work are almost all experienced professionals.

However, since you never know when the soil conditions might change,Larger machines are safer.That's it.

It's faster to get the job done quickly and efficiently with a large machine than to work nervously with a small one.

Please be careful, as mistakes made during drilling are difficult to correct.

 

Machines these days are becoming smaller than they used to be.

However, while it would be fine if a small one could drill holes, it actually takes an incredibly long time, so it’s not worth the effort.

It’s more profitable to just fly in and out quickly with large and medium-sized planes, lol.

You'll often see "drilling capacity" listed in machine catalogs, but you should assume it's generally about 70 percent of the catalog value.

I guess it would work if I went full power, but what if I did the work at full power, caused a jam, and couldn't get it out...

It is best to select a larger machine based on the conditions at the job site.

 

What is jamming?:

This refers to a condition in which the drilling unit of a drilling machine becomes stuck inside the borehole and is unable to rotate.
Possible causes of constriction include bore wall collapse or extrusion, bore wall bending, poor water supply, and slime buildup.

 

Sometimes the perforated pipe won't fit, but I'll talk about that tomorrow.

 

See you later.
