Kaiji<\/figcaption><\/figure>\nBut it looks like I'll be working on the 30th, the 1st, and the 2nd...<\/p>\n
Even though it's a Ministry of Land, Infrastructure, Transport and Tourism site... (lol)<\/p>\n
There's just no helping it. The construction schedule takes priority!!<\/p>\n
I'm sure some of you have work commitments, but it would be best if we could take turns taking time off to work things out.<\/p>\n
\nBut that's beside the point.<\/p>\n
Control the flow and position of the water.<\/h3>\n
![\"Reduce](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/IMG_1753-600x450.jpg\")
<\/p>\n
Do you know what this is?<\/p>\n
This is a temporary waterway running alongside the slope. There are steps formed with mortar.<\/p>\n
I often build them on the banks, and they help slow down the flow of rainwater.<\/p>\n
The steps in this waterway also slow down the flow, preventing the water from rushing through all at once.<\/p>\n
This principle is commonly applied in our daily lives; a prime example is a river.<\/p>\n
There are a lot of steps here, aren't there?<\/p>\n
![\"Fish](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/002-600x450.jpg\")
<\/p>\n
This is what the steps used to look like.<\/p>\n
I'm guessing this probably doubles as a fish passage, too. For ayu and stuff. (It's a really tiny river, though lol.)<\/p>\n
When you're doing river construction, timing the water level changes and the fish passage are pretty crucial (lol).<\/p>\n
![\"Step\"](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/e5fbee80-600x450.jpg\")
<\/p>\n
If you let the water accumulate to a certain level first and then let only the excess overflow, the flow rate will slow down and the water will become calmer.<\/p>\n
As for where to use this on the slope,<\/p>\n
![\"Flow](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/IMG_1895-600x450.jpg\")
<\/p>\n
In this case, the purpose is to direct rainwater flowing down the slope into the drainage channel, but,<\/p>\n
This water is also being channeled into the waterway to reduce the flow velocity and prevent erosion.<\/p>\n
Reducing the flow velocity helps prevent erosion and collapse.<\/p>\n
Water is incredibly powerful\u2014it can even destroy structures.<\/p>\n
![\"Prevention](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/45dbb2c8817505f48cb88c471f075866-600x460.jpg\")
<\/p>\n
For example, in the photo above,If there were no waterways<\/span>...When it rains, the water really runs off.<\/p>\nIf a step is created with mortar along the red line, the flow velocity drops sharply.<\/p>\n
Basically, you direct the water to hit something to slow it down.<\/p>\n
On the sloped sections of the shoulder, such as those on a formwork frame, create bumps like this so that the formwork doesn't slide along the shoulder,<\/p>\n
By periodically releasing water onto the front face of the retaining wall, you can prevent water from seeping into the wall\u2019s shoulders and also prevent erosion.<\/p>\n
Unless there is a drainage channel, it is best to disperse the water on the slope as much as possible to minimize the impact on vegetation restoration measures and the like.<\/p>\n

<\/p>\n
A director who shows that kind of little thoughtfulness really knows how to get the job done.<\/p>\n
There might be a few minor details to nitpick, but I think it's wonderful.<\/p>\n
A long time ago, I, too, was taught the above by a senior director and have been putting it into practice ever since.<\/p>\n
Since this isn't something government offices or anyone else will see, it's purely for my own satisfaction, but,<\/p>\n
When it rains and the rain flows over the mortar bump on the shoulder of the frame and comes out the front of the frame, I just think, \u201cWhoa! That feels great!\u201d (lol)<\/p>\n
<\/p>\n

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here.
