<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
Lately, we\u2019ve been doing a lot of dry stone masonry work in Nagoya City.<\/p>\n
What's more, since we're working in an upscale residential neighborhood in Nagoya, we have to be quite careful.<\/p>\n
Since this job site wasn't in a cramped area, it wasn't too bad, but if it were cramped, it would be really tough, wouldn't it?<\/p>\n
<\/p>\n
Since we haven\u2019t applied for a road use permit or similar authorization, we only carry out work within the scope that can be completed in a single day and wrap up operations by the end of that day.<\/p>\n
If it were a public space, we\u2019d get a road use permit and go all out, but that would increase the client\u2019s costs, so we\u2019re keeping it to a minimum as much as possible.<\/p>\n

<\/p>\n
We are enclosing the work area on all sides and performing chiseling and grouting.<\/p>\n
So, when you look inside after cutting it open, you'll find that it's surprisingly full of dirt and sand.<\/p>\n
(The photo below shows us using a pressure washer to remove some of the dirt and debris.)<\/p>\n

<\/p>\n
At first glance, it doesn't look bad, so I thought, \"It's packed, so it should be fine, right?\"<\/p>\n
That's what people say.<\/p>\n
<\/p>\n
That's right. It's actually pretty packed, lol.<\/p>\n
It actually looks pretty good.<\/p>\n
On the other hand, if there are spots where the soil particles have washed away, sometimes only the stones get washed away...<\/p>\n
<\/p>\n
![\"Stone](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2022\/06\/0855123ecb7c755095b6cf5f14875247.jpg\")
<\/p>\n
In fact, because it\u2019s packed so tightly, the soil behind it actually pushes against the stone itself.<\/p>\n
Once the soil and rocks have been pushed aside, there\u2019s no way they\u2019ll go back, so all we can do is wait for it to collapse.<\/p>\n

<\/p>\n
This stone wall was built quite solidly by stonemasons of old, but,<\/p>\n
We\u2019ll carefully chisel out the joints to widen them as much as possible.<\/p>\n
Then, we use a high-pressure washer to wash away the loose soil and debris inside.<\/p>\n
Doing so increases the area of application, which in turn increases the surface area that can be bonded, thereby improving strength.<\/p>\n
<\/p>\n
However, there\u2019s a common misconception here: measures for stone masonry are, after all, merely cosmetic.<\/p>\n
A stone wall is made up of individual stones.<\/p>\n
By bonding them together with resin mortar, we create a \"chain.\"<\/p>\n
Maintaining continuity can prevent partial collapse.<\/p>\n
<\/p>\n
However, when it comes to whether it can withstand internal pressure (earth pressure), I can\u2019t say for sure that it can!<\/p>\n
After all, there\u2019s no choice but to use appropriate construction methods to deal with earth pressure.<\/p>\n
These include rebar installers and drainage workers.<\/p>\n
This will be determined based on the results of the investigation.<\/p>\n
Please keep in mind that while it does make it much less likely to crumble, it\u2019s not a guarantee.<\/p>\n
Stone walls that have already collapsed or are showing signs of spalling require appropriate measures.<\/p>\n
<\/p>\n
See you later.<\/p>","protected":false},"excerpt":{"rendered":"
