Hello, everyone.
This is Enta.
Lately, we've been drilling away at full speed with a suspended drill rig.
So, this is about a minor slime ejection issue that people tend to run into quite often.
Take a look at this drill hole.
Slimes are pouring out in droves.
This is a common sight, but what really matters is...It's important to keep your hands close byThat's it.
There are workers who hang from the slope to set the placement position, right?
If you have a steadier hand, drilling goes much faster.
That's because, during drilling operations, it's quite difficult to see the slime that comes out of the hole as drilling progresses.
It's easier if the control panel is on top and the drilling area is below, but if it's the other way around, you can't see it.
I can't see because the machine is in the way.
So, the person at the controls checks and gives the signal.
Clean the hole immediately as soon as you notice that fewer slimes are coming out.
Although I say “cleaning,” it’s really just a matter of rotating the bit in the direction of removal, but doing this alone will increase the drilling speed.
Increasing the drilling speed isn't just about drilling.
This includes everything from drilling the holes to inserting the rebar.
That's what "pouring and installing" means. (Pouring and installing)
Rather than just drilling holes haphazardly, it’s clearly faster to thoroughly remove the slurry as you go so the rebar slides in smoothly, considering the extra work involved in re-drilling.
If the operator on-site provides clear instructions regarding the delicate slime discharge conditions, drilling should proceed more quickly.
When drilling with a suspended drill rig, the speed varies depending on the operator's technique.
In my case, my hands tell me when to raise or lower the drill, so I just drill according to those instructions.
Of course, the surgeon also needs a good sense of where to drill.
Good taste comes from knowledge and experience.
Please keep honing your sense of style.
Of course, this will vary depending on the soil type, so please keep bit selection in mind as well.
See you later.
