Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

Have you heard of \"Ganta stacking\"?<\/p>\n

 <\/p>\n

What Is \"Ganta Stacking\"?<\/p>\n

\"Ganta-zumi\" refers to,A retaining wall constructed by stacking and combining various materials, such as concrete scraps, bricks, and roof tiles<\/mark>refers to.<\/span>This type of retaining wall is constructed using reused materials from demolition; because the surface is covered with mortar, it is difficult to tell at a glance what materials were used. Ganta-style retaining walls are often found in older structures and are considered structurally unstable, so caution is required. (Google)<\/span><\/div>\n

\"Ganta<\/p>\n

It's a guy like this.<\/p>\n

Since this isn't a stone wall, it's very unstable.<\/p>\n

That's because they come in all different sizes and depths.<\/p>\n

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

Or rather, I'm not really sure. How unstable is it, exactly?<\/p>\n

 <\/p>\n

So, for this project, we\u2019ll be installing this Ganta piling using the Moldam method, along with drainage to prevent collapse.<\/p>\n

\"Ganta<\/p>\n

It contains all sorts of things, like bricks and concrete debris.<\/p>\n

\"Ganta<\/p>\n

A survey stake marked \"Kanagawa Prefecture\"?<\/p>\n

That's amazing, isn't it?<\/p>\n

They used whatever materials they had on hand to pile up a barrier and stop the soil from eroding away from the land.<\/p>\n

 <\/p>\n

Even with a pile of Ganta as bad as this, there\u2019s one type of construction work you absolutely must never do: sprayed mortar lol<\/p>\n

Because if you hide everything, you won't know what happens next.<\/p>\n

The sealed construction method won't work.<\/p>\n

 <\/p>\n

We'll be as transparent as possible and take appropriate measures.<\/p>\n

Since this project uses a combination of Mouldam and dewatering boring, the likelihood of collapse\u2014even during heavy rain\u2014is quite low.<\/p>\n

 <\/p>\n

While construction methods that increase resistance to landslides are important, there\u2019s also the preventive approach of keeping the mountain from collapsing and allowing the force of the water to flow away, isn\u2019t there?<\/p>\n

I've said this many times, but please stop using that construction method where you just hide things, lol.<\/p>\n

 <\/p>\n

See you later.<\/p>\n

 <\/p>\n

P.S. Yokohama City has a checklist for stone masonry,<\/p>\n
