Hello, everyone.
This is Enta.
It's still warm, but it looks like winter will really set in starting next week!
Let's stay focused!!
But that's beside the point.
Dangers on the Upper Part of the Roadway
When installing the rope, check the conditions at the top of the construction slope.
This is a fairly common type of accident that occurs during construction on the upper part of the road shoulderThere are falling rocks coming from even higher up than where the rope is stretched.
The ropes we use to descend while wearing safety harnesses are usually secured to standing trees.
That tree sways quite a bit in the wind, even though its trunk is over 20 centimeters in diameter.
If the trees are swaying, that means the ground is shaking.
As a result, a rockslide occurs.
Mountains with steep upper slopes or areas with loose rocks are particularly dangerous.
As long as the rocks aren't too big,
Green Net and Trical Net...can be prevented.
However, going beyond that is extremely dangerous.
Just a 1-centimeter-sized stone passed right by my ear, andWhoosh!It has such powerful destructive force that it makes a *thud* sound.
If it goes beyond that, there’s a very real risk to one’s life, and,
As a result, many people have died.
Please take all necessary safety precautions to minimize the risk as much as possible.
By the way, depending on the terrain, a single rock fragment can travel about 2.0 meters when it falls. (Handbook on Rockfall Countermeasures)
That means,If possible, the net at the top of the deck should also be about 2.0 metersIt's best to install it by that time for peace of mind.
If possible, 2.5 meters would be safer!
See you later.
