Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

\"Self-Drilling<\/p>\n

Since I usually work on slopes like this one in the mountains, installing rebar, I have to be extra careful when working on construction sites in the city.<\/p>\n

As expected, measures to address noise, dust, and other issues are needed...<\/p>\n

There's nothing much to do out in the mountains, so I can really get down to work.<\/p>\n

As expected, since we can\u2019t start early or work overtime in the city, the construction time is shorter.<\/p>\n

That does mean the price will inevitably go up, doesn't it?<\/p>\n

 <\/p>\n

So, this is a continuation of the previous post.<\/p>\n

\"Plan<\/p>\n

Let me make one thing clear from the start.<\/p>\n

We are a public works construction company that specializes in the design and construction of public works projects.<\/p>\n

We carry out construction in accordance with national design and construction standards.<\/p>\n

The same applies to prefectures and municipalities.<\/p>\n

For that reason, money is based on that standard.<\/p>\n

Since it is paid for with tax dollars, the amount is determined based on fair judgment, soThere are absolutely no rip-offs or anything like that.<\/strong><\/span>Please keep that in mind.<\/p>\n

The amounts I'm about to mention are based on national standards.<\/p>\n

 <\/p>\n

And that unit price plus on-site conditions.<\/p>\n

Please keep that in mind when considering the matter.<\/p>\n

\n

\"Plan<\/p>\n

I should really start with stone masonry reinforcement, but for now, I\u2019ll list the reinforcement costs for L-shaped retaining walls (retaining walls).<\/p>\n

Estimated Quantity<\/h3>\n

 <\/p>\n

Reinforcing Bar Installer, 5 m<\/p>\n

Top row: 9 pieces \u00d7 5 m = 45 m<\/p>\n

Bottom row: 9 pieces \u00d7 5 m = 45 m<\/p>\n

Drilling for drainage: 5 holes \u00d7 4 m = 20 m<\/p>\n

Pressure plates: 18<\/p>\n

 <\/p>\n

Reinforcement Bar Insertion Drilling Costs<\/h3>\n

Site Conditions III<\/p>\n

\"Site<\/p>\n

15,000 yen per meter<\/p>\n

Actual market unit prices (The government-set unit prices do not include drilling depths of 5 meters; the maximum is actually 3 meters.)<\/p>\n

 <\/p>\n

Upper and lower levels: 90 m \u00d7 15,000 yen = 1,350,000 yen<\/p>\n

If we apply time-based restrictions and length-based adjustments to this, the increase would be 1.15 + 0.2 = 1.35.

The unit prices for retaining wall reinforcement are as shown above.<\/p>\n

These are merely reference values, and there can be significant variations depending on the site.<\/p>\n

Anyway, living in such a cramped space is tough, so please bear with me on that one lol<\/p>\n

 <\/p>\n

That's damn expensive!!!<\/span><\/strong><\/span><\/p>\n

You might think that, but when you consider rebuilding the retaining wall...<\/p>\n

And in reality, most of the retaining walls are about half this size.<\/p>\n

There aren't many retaining walls this long at the moment.
\n(For a typical single-family home, the average cost is around 1.5 to 2.5 million yen.)<\/p>\n

 <\/p>\n

\"Drainage<\/p>\n

I can't afford to spend that much, but at least something for heavy rain protection!!??<\/p>\n

If that sounds like you, just draining the water alone can be very effective!<\/p>\n

Next time, we'll talk about the cost of stone retaining walls.<\/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\/retaining-wall-reinforce-8-cost\/#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 11:01:25","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\/2025\/10\/a8060da554b7b97a8a2c79f6466289fb.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/56358","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=56358"}],"version-history":[{"count":12,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/56358\/revisions"}],"predecessor-version":[{"id":63855,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/56358\/revisions\/63855"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/56040"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=56358"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=56358"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=56358"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
