Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

The other day, at a job site where Enta is the contractor, we held a site tour for representatives from the Public Works Research Institute, with the cooperation of the general contractor.<\/p>\n

What on earth is that, anyway!?<\/p>\n

That's kind of how it is, lol<\/p>\n

 <\/p>\n

Public Interest Incorporated Research Institute for Civil Engineering<\/a><\/p>\n

\"Public<\/p>\n

\ud83c\udfd7 What is the Public Interest Incorporated Foundation, Public Works Research Institute?<\/h2>\n

It is a national research institute that supports Japan's infrastructure through research.<\/p>\n

Commonly known as: Doken<\/p>\n

Our research covers the entire field of civil engineering, including roads, bridges, tunnels, rivers, dams, and slope stabilization.<\/p>\n

A research institute affiliated with the Ministry of Land, Infrastructure, Transport and Tourism,
\nNational Standards\u30fbGuidelines and Technology<\/span><\/strong>I'm currently working on the source material for it<\/p>\n

\ud83d\udd0d What are you doing?<\/h3>\n

Research on the Safety and Durability of Infrastructure<\/p>\n

Research on Disaster Prevention and Mitigation Technologies for Earthquakes, Heavy Rainfall, and Landslides<\/p>\n

Verification of New Construction Methods, Materials, and Design Techniques<\/p>\n

Development of Technical Standards and Manuals for National and Local Governments<\/p>\n

\ud83d\udc49 Used on-site<\/h3>\n

You can safely assume that the Public Works Research Institute is behind the \u201cDesign Guidelines,\u201d \u201cTechnical Standards,\u201d and \u201c\u25cb\u25cb Guidelines.\u201d<\/p>\n

\ud83e\udde0 From a slope engineer's perspective<\/h3>\n

Research on slope failures, rockfalls, and landslides; ground anchor systems, shotcrete retaining walls, and soil reinforcement works<\/p>\n

\"Will this construction method be approved?\"
\n\"How do we explain safety?\"
\nThis is what underpins that theoretical framework.<\/p>\n

\ud83d\udccd The Organization's Role<\/h3>\n

Official Name: National Research and Development Agency, Public Works Research Institute<\/p>\n

Headquarters: Tsukuba City, Ibaraki Prefecture<\/p>\n

It's a government research institute, but it's incredibly closely tied to real-world practice!<\/p>\n

\n

Ground Anchor Construction Site Tour<\/h3>\n

We invited the Public Works Research Institute to the site and held a demonstration of ground anchor construction!<\/p>\n

\"Public<\/p>\n

Of course, I got permission from the general contractor to have them come to the Public Works Research Institute, but naturally, I had them do the construction work! lol<\/p>\n

 <\/p>\n

I think research is fine in and of itself.<\/p>\n

However, construction is key to applying real-world experience to research!<\/p>\n

So, I had them drill a hole for me lol<\/p>\n

 <\/p>\n

Press!<\/strong><\/span><\/p>\n

Spin!<\/strong><\/span><\/p>\n

A hit!<\/strong><\/span><\/p>\n

 <\/p>\n

Teach me how to balance these three elements, and then let's start drilling!<\/p>\n

So, they drilled a hole about 10 meters deep for me.<\/p>\n

 <\/p>\n

To be honest, as a researcher at a government agency, I just can't do something like this!<\/p>\n

I think normally they wouldn't let me do it because they'd say it's dangerous.<\/p>\n

I'll have someone do that for me ^^<\/p>\n

Everyone knows that there are many things you can\u2019t understand until you try them, so they really enjoyed it.<\/p>\n

He said he could understand the machine's behavior as clearly as if he were holding it in his hands.<\/p>\n

(We provide support while giving careful consideration to safety.)<\/p>\n

\"Public<\/p>\n

They carefully oversaw the entire process\u2014from drilling and grouting to tendon insertion\u2014until the job was completed.<\/p>\n

 <\/p>\n

We had actually planned to have the cement slurry mixed on the second day, but due to the heavy snow, we couldn't proceed with the work...<\/p>\n

That's too bad! (It's still going on, so more to come lol)<\/p>\n

 <\/p>\n

Next time, we'll cover the tensioning process for this ground anchor installation!<\/p>\n

Going forward, I hope you\u2019ll come by regularly to thoroughly learn the implementation process.<\/p>\n

What happens when people learn the facts is that the \u25cb\u25cb Guidelines and the \u25cb\u25cb Construction Manuals begin to change.<\/p>\n

The unnecessary and odd aspects are becoming more and more like what happens on the ground.<\/p>\n

The Public Works Research Institute is the organization that truly incorporates those points!<\/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\/prl-site-tour\/#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":"2026-08-20 10:15:16","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\/2026\/01\/1f3a90fbeaf5ddca57f02acf9387a879.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/58064","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=58064"}],"version-history":[{"count":3,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/58064\/revisions"}],"predecessor-version":[{"id":58077,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/58064\/revisions\/58077"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/58076"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=58064"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=58064"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=58064"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
