Hello, everyone.

This is Enta.

When erecting scaffolding for ground anchor installation or rebar insertion work, how do you give instructions to the scaffolding crew?

For a drilling machine of this size, what is the recommended scaffolding spacing?

If you set up scaffolding meticulously for structural calculations, it requires a significant amount of time and materials.

Therefore, assuming that we are erecting a scaffold that is reasonably safe—

Regarding the scaffolding spacing,

For drilling machines weighing 500 kg to 1,000 kg, the installation spacing (pitch) is 1,500 mm.

Rolling distance = 500 mm

For 1.5-metric-ton-class drilling rigs, the spacing (pitch) between drilling sites is 1,000 mm or less.

Rolling distance = 500 mm

*This is for reference only.

The key is how you roll it.

This refers to the single-wall pipe that runs directly beneath the scaffolding.

This must be spaced at 500mm intervals, and the boards won't split,

Machinery can also be moved safely.

Also,Bracing directly below the drilling locationIt would be even better if there were one.

As expected, the core drill uses the weight of the scaffolding as a reaction force.

When the machine presses down, the scaffolding bends backward.

In that case, you can rest assured if there are diagonal braces capable of withstanding that force installed in the same direction as the machine.

If it's a lightweight drilling rig weighing around 500 kg, you can feel fairly confident using it on just about any type of scaffolding, but

Heavy-duty drilling machines are very dangerous because they are so powerful.

I've never seen a scaffold collapse, but I've seen them sag quite a few times.

そんな時はダブルクランプだとかで対応するんですが、

Large, large-diameter drilling machines (5 metric tons) and the like are really scary.

When it comes to scaffolding, it’s definitely more reassuring to leave it to the professionals.

当然ですが、足場の安定計算を行う事も重要です。

Come to think of it, I realized I haven't been doing any large-aperture photography lately, but,

Well, I guess I can't do anything else except work on the slope.

See you later.
