Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

In response to a question from a recent blog post, I was asked what to do if the clay layer is loose.<\/p>\n

In reality, though, I have no choice but to drill while carefully watching the Kriko (slime), but,<\/p>\n

Actually, there are some good bits these days, lol<\/p>\n

Have you ever seen this?<\/p>\n

It comes with a back blow.<\/p>\n

I hear it can handle a certain amount of sandstone.<\/p>\n

Digging a Water Channel Through a Clay Layer<\/h3>\n

In clay layers, digging a water ditch is quite a challenge.<\/p>\n

That's because using water makes everything all soggy, you know? It's tough under Site Conditions I.<\/p>\n

It's difficult because its performance is significantly inferior to that of rotary percussion.<\/p>\n

Other than that, I guess the key is to move slowly while gradually chipping away with the bit~<\/p>\n

That's what I think.<\/p>\n

As expected, the speed of drilling depends on how well you can remove the slurry.<\/p>\n

I guess I just have to keep digging, step by step, with great care.<\/p>\n

Since it\u2019s hard to see from the operating room, it really drives home how important it is to pay attention to what you\u2019re doing right in front of you.<\/p>\n

 <\/p>\n

See you later.<\/p>\n

P.S.: By the way, the bits mentioned above areHirado Metal Industries, Inc.<\/strong><\/span><\/a><\/p>\n

If possible, please have it done at the Yokohama branch. lol<\/p>\n

joining a major construction company specializing in slope stabilization, I went independent at the age of 32. 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\/suspension-drilling-bit-types-part2\/#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 13:32:24","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\/2017\/09\/7f02bb067f573f4348ee87e5cd2808fe.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/4445","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=4445"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/4445\/revisions"}],"predecessor-version":[{"id":60730,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/4445\/revisions\/60730"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/4442"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=4445"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=4445"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=4445"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
