Hello, everyone.
This is Enta.
What do you think of vegetation engineers?
I think it's a recent trend that it has decreased significantly.
Why is that?
One reason is maintenance.
In our aging society, there are fewer and fewer people available to perform maintenance.
Therefore, when you consider the effort involved in mowing the grass and other tasks, applying sprayed mortar is actually more cost-effective.
Another issue is that vegetation engineering measures can’t keep up with the localized torrential rains we see these days.
In particular, for slopes covered solely with vegetation, it becomes difficult to rely solely on construction methods designed strictly to prevent erosion.
It cannot withstand the earth pressure and water pressure (excess pore water pressure) coming from deep within the ground.
That means that, at the very least, if the retaining wall isn't built, the structure will collapse.
This means that construction methods that were effective in the past are no longer suitable for today's times.
I feel that we have entered an era where we need to rethink the construction methods we have been using for decades.
While books and the like remain largely unchanged, I think it’s important for design philosophies and metrics to evolve to some extent in line with the times.
In the future, if vegetation engineering or similar measures are included in the design for a site, is it really okay to implement them here?
I think it’s best to fully understand the implications of installing it here and consider making design changes or other appropriate adjustments.
Personally, I think it would be better to use a sealed sprayed mortar system in combination with drainage measures to ensure long-term maintenance.
Keep as much water out of the mountains as possible, and drain as much water as possible.
I feel like this part is very important.
See you later.
The deadline is Friday, October 18, 2024.
