Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

\"On-Site<\/p>\n

I believe this falls within the legal framework, but if it were within the boundaries shown in the photo, how would you rule on it?<\/p>\n

The area within the design boundaries is designated for landscaping.<\/p>\n

 <\/p>\n

On the left is bedrock.<\/p>\n

On the right side, the ground consists of soil mixed with sand, with rocks exposed in places.<\/p>\n

Eighty percent of this mountain consists of exposed bedrock.<\/p>\n

In particularly difficult areas, we used static blasting agents to break up the rock in sections.<\/p>\n

 <\/p>\n

The design calls for landscaping\u2014what do you all think?<\/p>\n

There are also sections with a gradient of 6 minutes or more in the earthwork area.<\/p>\n

 <\/p>\n

Actually, it\u2019s not impossible to plant vegetation there. (Although it would be difficult in the long run if the ground is solid bedrock.)<\/p>\n

It grows to some extent on the rocky area on the left as well.<\/p>\n

However, based on current trends in slope construction, the options are either full-surface shotcrete or mortar spraying within the formwork.<\/p>\n

 <\/p>\n

For the past few years or so,Long-term maintenance costs<\/span><\/strong><\/span>Considering this, the sealed construction method is the mainstream approach.<\/p>\n

Open-Type and Sealed-Type Frame Structures<\/a><\/p>\n

When I say that \"sealed enclosures are the norm,\" the government officials seem strangely convinced.<\/p>\n

Apparently, maintenance is indeed an issue in some government offices; mowing the grass costs money, and above all, it requires manpower.<\/p>\n

From the government\u2019s perspective\u2014since it\u2019s responsible for managing these matters\u2014it naturally wants to minimize them as much as possible.<\/p>\n

 <\/p>\n

Recent trends at NEXCO also show a shift toward sprayed concrete.<\/p>\n

They're spraying concrete nonstop on the embankment next to the highway after clearing the trees, aren't they?<\/p>\n

In addition, repairs to the Nagata slope in the past were also carried out by applying shotcrete over existing shotcrete. (Ote Special Construction Method)<\/p>\n

 <\/p>\n

Well, that\u2019s just the way things are these days. (Not that I intend to blame everything on the times.)<\/p>\n

Before it gets to the point where no one can manage it anymore, we\u2019re gradually switching to construction methods that don\u2019t require management.<\/p>\n

\"Think\"<\/p>\n

That leads to a simple idea: we just need to come up with construction methods that don't require supervision, right?<\/p>\n

I wonder what kind of construction methods will emerge that are easy to install and maintenance-free.<\/p>\n

 <\/p>\n

For now, I think we can proceed with the airtight construction method without any issues.<\/p>\n

At this job site as well, even for areas with only partial soil and sand, we ended up using sprayed mortar.<\/p>\n

It used to be said that with the sealed construction method for earth-filled sections, the soil inside would be washed away by rain, leaving the interior hollow, but,<\/p>\n

Actually, it doesn't seem to be that big of a deal.<\/p>\n

 <\/p>\n

Past facts are present lies, future rumors<\/span><\/strong><\/span>That's kind of how it is, lol<\/p>\n

 <\/p>\n

Civil engineering has been quantified based on empirical data and forms the foundation of the field today.<\/p>\n

This means that those figures will continue to change over time as experience levels evolve.<\/p>\n

Even in an industry that you might think hasn't changed in over 30 years (based on my experience), you can see that it's gradually changing, right?<\/p>\n

 <\/p>\n

The closed-system method is currently the mainstream approach for in-frame spray application! (Though I\u2019m probably being a little biased here, lol)<\/p>\n

 <\/p>\n

See you later.<\/p>","protected":false},"excerpt":{"rendered":"

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. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/closed-type-mainstream\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-08-21 12:54:07","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/06\/IMG_2614.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/41113","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=41113"}],"version-history":[{"count":2,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/41113\/revisions"}],"predecessor-version":[{"id":64203,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/41113\/revisions\/64203"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/7018"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=41113"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=41113"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=41113"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
