Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

My back is healing well.<\/p>\n

Those lower back exercises are something else.<\/p>\n

By the way, this is all I do lol<\/p>\n

What Is the \"Just These Exercises\" Method for Relieving Lower Back Pain? | Health and Longevity Network<\/div>
https:\/\/www.tyojyu.or.jp\/net\/kenkou-tyoju\/shintai-kenkou\/yotsu.html<\/div>
Lower back pain refers to uncomfortable symptoms such as pain or stiffness in the area from the lower back to the buttocks. Causes of lower back pain can include cancer metastases, multiple myeloma, or fractures associated with osteoporosis; therefore, if you experience persistent pain, you should consult a healthcare professional. In this article, we will explain the typical mechanisms behind lower back pain and introduce \u201cKore Dake Taiso\u00ae,\u201d a set of exercises designed to alleviate it.<\/div><\/div>
<\/div><\/div><\/a><\/div><\/div>\n
\n

But that's beside the point.<\/p>\n

What should be done about exposed stones (rocks) on slopes?<\/p>\n

I get asked that a lot.<\/p>\n

\"Exposed<\/p>\n

You often see rocks on slopes that are half-buried, don\u2019t you? You can\u2019t even tell how big they are.<\/p>\n

 <\/p>\n

As a general rule, if a stone is loose, you should remove it.<\/p>\n

However, since it doesn't float and it's impossible to gauge its depth, and considering the potential damage, harm, and impact it could cause below if it were to fall, it would be wiser not to drop it.<\/p>\n

So what should we do?<\/p>\n

As an option<\/p>\n

1. Shave<\/span><\/strong><\/span><\/p>\n

\"Megalith<\/p>\n

For rock drills and similar equipment, should we use a pick or a chisel to break the rock into smaller pieces, or should we use chemicals?<\/p>\n

As described above, remove only the top layer and apply a surface protection coating.<\/p>\n

It's fairly common, but it can get quite troublesome when there are a lot of them.<\/p>\n

This method is often used at sites where there are rocks in the mountains and machinery can\u2019t get in, so the work can only be done manually on a small scale.<\/p>\n

This construction method involves cutting the material into small pieces so that, even if it were to fall, the damage would be minimized.<\/p>\n

Rockfall protection nets and other measures will be installed along the road surface.<\/p>\n

 <\/p>\n

2. Strengthen the roots<\/span><\/strong><\/span><\/p>\n

\"Foundation<\/p>\n

This is also a fairly common practice: the larger the boulder, the more likely it is that the base will be filled with concrete or sprayed concrete to prevent it from rolling. Depending on the size of the boulder, methods such as ground anchors, other types of drilling, or self-drilling rock bolts are used to provide counterforce.<\/p>\n

\"Gero:<\/p>\n

It's the same as the root reinforcement work we did on the boulders before.<\/p>\n

\"Gero:<\/p>\n

(I was supposed to fill this in with spray, but the rock was so huge that I ended up using a ton of it lol)<\/p>\n

3. Wrap it around the frame<\/span><\/strong><\/span><\/p>\n

\"Framework<\/p>\n

To be honest, this might actually be the quickest way.<\/p>\n

However, if it's too big, I think the most common method is still to trim it down first and then wrap it around the frame.<\/p>\n

 <\/p>\n

4. Winding with a rope-winding machine<\/span><\/strong><\/span><\/p>\n

\"Rope<\/p>\n

If possible, applying a mortar spray might help slow down the deterioration of the rock.<\/p>\n

As long as it's covered with rope, it probably won't move, so it should be fine for now.<\/p>\n

In most cases like this, rockfall protection nets and other measures are installed along the road surface.<\/p>\n

 <\/p>\n

5. Break Through with a Rebar Insertion Tool!<\/span><\/strong><\/span><\/p>\n

\"Reinforcing<\/p>\n

In rare cases, a construction method is used in which the rock is not removed but is left in place, and tension is applied using techniques such as rebar insertion or ground anchors to contain the rock\u2019s energy.<\/p>\n

Surprisingly, it\u2019s often used in combination with foundation reinforcement, but it\u2019s possible as long as the rock is solid.<\/p>\n

If there are concerns that rocks might shift during construction, this method may be used in conjunction with techniques such as rope anchoring.<\/p>\n

 <\/p>\n

6. Depending on the construction method, remove all of them.<\/span><\/strong><\/span><\/p>\n

 <\/p>\n

\"Rock<\/p>\n

After removal, the hole is filled by packing sand mixed with cement into sandbags, or by replacing the area with small pieces of rock mixed with mortar, followed by surface finishing.<\/p>\n

Since removing a large rock makes it highly likely that the surrounding area will become unstable, this practice is rarely performed these days. (Rock removal work used to be quite common in the past.)<\/p>\n

If the only issue is the rock and everything else is fine, we leave it as is; however, in most cases, we install retaining walls or similar structures. Additionally, if the area to be cleared is at a high elevation, rockfall protection netting or similar measures are installed, as described above.<\/p>\n

 <\/p>\n

7. High-Energy Rockfall Mitigation Measures<\/span><\/strong><\/span><\/p>\n

This is a rockfall protection netting system designed to prevent the fall of large boulders.<\/p>\n

These days, there are many different types available, and patented products\u2014which can only be installed by companies that have obtained the installation rights\u2014are the mainstream.<\/p>\n

If you search for terms like \"rockfall high energy\" on Google, you'll find it.<\/p>\n

I\u2019ve only been through this once myself, so I don\u2019t know the details.<\/p>\n

If I\u2019m just thinking about the construction cost, I do know that it would be cheaper to use a combination of partial removal, rope installation, and rockfall prevention netting to reinforce the foundation, lol.<\/p>\n

I guess the design ends up using high energy due to on-site conditions and other factors. Not that I know, lol.<\/p>\n

I often hear that if energy costs get too high, the general contractor could end up operating at a loss.<\/p>\n

 <\/p>\n

This project involved measures to address boulders, rocks, and loose rocks in slope stabilization work.<\/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\/large-rock-7-countermeasures\/#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 06:20:22","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\/2021\/08\/e9e85f0dda61e3d76dda55d7858baaa6.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/51281","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=51281"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/51281\/revisions"}],"predecessor-version":[{"id":62720,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/51281\/revisions\/62720"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/45019"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=51281"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=51281"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=51281"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
