Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

Basic Principles of Landslide Mitigation Measures (Part 1)<\/a><\/p>\n

This is a continuation of my previous post.<\/p>\n

\"Support<\/p>\n

The brown area is the soil mass that is about to be moved, and the orange area is the fill.<\/p>\n

Pile soil at the edge of the section that is trying to slide to resist the force causing it to move.<\/p>\n

Simply put, the embankment counteracts the force that causes the structure to slide.<\/p>\n

 <\/p>\n

In our line of work, there are often sites where we compact the fill, right?<\/p>\n

In emergency construction projects, in particular, they stack flexi-bags (ton bags) against slopes that are on the verge of collapsing to stabilize them, right?<\/p>\n

That's it.<\/p>\n

\"Retaining<\/p>\n

For example, a method where soil is safely removed using an excavator while being held in place by a flexible container bag.<\/p>\n

It gives you a sense of security, doesn't it?<\/p>\n

When a flexible container bag is in use for an extended period, or<\/p>\n

Before the structure starts to deteriorate, we slope contractors will apply sprayed mortar.<\/p>\n

 <\/p>\n

Since it\u2019s basically in the field of earthwork, we don\u2019t really have much to do with it.<\/p>\n

As an aside, a long time ago, during emergency earthquake-related construction work, we sprayed mortar onto weather-resistant flexi-bags used to secure the embankment, and,<\/p>\n

We once installed rebar through it.<\/p>\n

Since it was only a temporary setup, the gaps in the flexible containers weren't an issue, but,<\/p>\n

I still wonder about that lol<\/p>\n

But I think it would be a total disaster if we kept injecting it until it was completely filled, lol.<\/p>\n

 <\/p>\n

On slopes or ground that appear to be slipping or are already slipping,<\/p>\n

Since backfill can be applied effectively and quickly, it\u2019s really the absolute basics.<\/p>\n

There was some soil removal the other day, but for now, the idea is to just pile on the fill!<\/p>\n

 <\/p>\n

See you later<\/p>\n

If you notice any abnormalities in your home\u2019s foundation or backfill, shouldn\u2019t you drain the water first? (For the general public)<\/a><\/p><\/blockquote>\n
