<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
The other day, we installed a drain at the company's storage yard.<\/p>\n
That said, all I really did was dig a hole with a rotary hammer and fill it with crushed stone, lol.<\/p>\n
This area used to drain well, but,<\/p>\n
It appears that the soil has compacted over time, causing poor drainage, so we installed drainage pipes.<\/p>\n
<\/p>\n
This time, we drilled a hole about 10 meters deep and filled it with crushed stone.<\/p>\n
<\/p>\n
After retrieving the liner, fill the casing completely with crushed stone and pack it down while striking it with the machine's hammer.<\/p>\n
Repeat this process, and after retrieving the casing, secure it in place with an iron pin.<\/p>\n

<\/p>\n
And that completes the drain.<\/p>\n

<\/p>\n
Just this alone is enough for it to quickly soak up the water around it.<\/p>\n
It works like a charm on rainy days.<\/p>\n
For large diameters, it\u2019s a sand-compacted crushed stone version, and it seems to be used as a support pile these days as well.<\/p>\n
<\/p>\n
In fact, simply installing these in a few places helps prevent liquefaction and makes the area less prone to flooding.<\/p>\n
There used to be almost no flooding, but there is now, isn't there?<\/p>\n
That\u2019s because the ground\u2014due to asphalt and other materials\u2014has become less able to absorb water.<\/p>\n
Just by taking these measures, the water level won't rise, and the soil will absorb it.<\/p>\n
<\/p>\n
Furthermore, it is exceptionally effective at dissipating water pressure during liquefaction.<\/p>\n
I feel that going forward, we\u2019ll need to start adopting these kinds of slightly unconventional construction methods (which are used in residential construction).<\/p>\n
I suppose slope stabilization isn't the only thing we can do when it comes to disaster prevention construction, is it?<\/p>\n
<\/p>\n
See you later.<\/p>","protected":false},"excerpt":{"rendered":"
