Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

Following my recent article on full-body harnesses, I received calls from several companies.<\/p>\n

Thank you very much.<\/p>\n

We\u2019ll provide you with all the necessary information, so please sell us high-quality products that are easy to work with and safe!<\/p>\n

\"Safety<\/p>\n

\n

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

Rotary Percussion Survey Drilling Technician<\/h3>\n

Did you know you can do that pretty easily? lol<\/p>\n

The key is that it's \"rough,\" but I can't be exact.<\/p>\n

That's because the data from borehole surveys is primarily collected in the form of core samples.<\/p>\n

Unless the soil sample is in the form of an undisturbed column, it will not be considered a valid sample.<\/p>\n

As I've mentioned before, slime is not a soil sample.<\/p>\n

\"Soil
http:\/\/www.chugoku-geo.or.jp\/book\/export\/html\/3<\/figcaption><\/figure>\n

So, the other day, I tried it out at a job site.<\/p>\n

Of course, it's rotary percussion.<\/p>\n

I had purchased a special core tube. It's time to try it out!<\/p>\n

\"Rotary<\/p>\n

The mechanism works by inserting a plastic bag into the tube; as you rotate and push it, soil samples are collected inside the bag.<\/p>\n

Add water little by little\u2014just enough to prevent the diamond blade from wearing down due to friction.<\/p>\n

If we can cover about 4 to 6 meters a day, that\u2019s a good day; in the worst-case scenario, we\u2019ll really come to a standstill.<\/p>\n

 <\/p>\n

And the result was a failure.<\/span><\/strong><\/span><\/p>\n

 <\/p>\n

That didn't work out, did it? (lol) As expected, it's not spinning fast enough!<\/p>\n

Rotary drilling machines operate at quite high speeds.<\/p>\n

It spins at about three to five times the speed of a rotary percussion instrument.<\/p>\n

Because it cuts through the mountain while pushing forward at such a high speed, the core comes out cleanly.<\/p>\n

Since rotary percussion rotates slowly, it pushes while shaving away the material with the blade, which causes it to become uneven.<\/p>\n

 <\/p>\n

To be honest, I thought it would go a little better, but it was a total failure.<\/p>\n

Finally, while packing the core into the outer casing, we pulled it up every 0.5 meters, and<\/p>\n

I changed my approach to removing the slime from inside the casing. I had no choice but to do so...<\/p>\n

 <\/p>\n

This isn't about what happened the other day, but this really is a case of \"leave it to the experts,\" isn't it? (lol)<\/p>\n

But I can't just give up here, so if another opportunity comes along, I'll give it another shot.<\/p>\n

It seems that you can adjust the rotational speed by replacing the orbit motor on the drill, but this is not recommended by the manufacturer.<\/p>\n

Honestly, it seems like it would be better to just buy a rotary drilling machine instead of changing that part, lol.<\/p>\n

\"Let's<\/p>\n

We compiled the preliminary sampling data, reference samples, and reports and submitted them to the general contractor.<\/p>\n

I guess the timing of the launch will depend on what the government and the consultants decide, lol.<\/p>\n

To be honest, I really hope it's way late...<\/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\/rotary-percussion-soil-survey-hard\/#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 09:33:08","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\/05\/ebeeb6ef325377d9b98bc0a9c21415d4.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6981","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=6981"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6981\/revisions"}],"predecessor-version":[{"id":60956,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6981\/revisions\/60956"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/6986"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=6981"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=6981"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=6981"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
