Hello, everyone.
This is Enta.
I just got back from Hokkaido the other day, and it's so hot...
Anyway, right now, the high temperature over there (at the site in Hokkaido) is the same as the low temperature in the Tokai region.
It sure feels hot, doesn't it? I actually wore a down jacket on my way home the other day, lol.
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 shoulder,There 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.
Even trees with a trunk diameter of 20 centimeters or more sway quite a bit.
When your mind wavers, the ground beneath you shakes.
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.
See you later.
