How to Make a Packer (Part 5)"},"content":{"rendered":"

Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

It looks like we'll be able to complete the dewatering drilling\u2014which we've been working on during our days off for the past few days\u2014by the deadline after all.<\/p>\n

Even after the cold snap passes, it's still cold, isn't it? lol<\/p>\n

\"Pressure<\/p>\n

Also, when it comes to pumps used for dewatering, a piston pump system\u2014which produces no pulsation\u2014is definitely the best choice.<\/p>\n

The pressure gauge broke, so it was running at 0.4\u20130.6 MPa lol<\/p>\n

*It looks like there might be a few openings in the Anchor Team in early February!<\/span><\/strong><\/span><\/p>\n

Why don't you give us a call? lol<\/p>\n

\n

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

How to Make a Packer (Part 5)<\/h3>\n

Last time, we covered the tip.<\/p>\n

This time, we'll look at the boundary between the fixed-length section and the free-length section.<\/p>\n

This distinction is actually quite difficult.<\/p>\n

This is usually where the leak starts.<\/p>\n

Actually, as long as the tip is securely tightened, it will still function properly as a fastener even if there\u2019s a slight leak at the top, but,<\/p>\n

The pressure gauge doesn't reach its maximum when pressurizing. (Although you shouldn't overpressurize either.)<\/p>\n

\"Cross-Section<\/p>\n

This is a cross-section of the packer during its manufacture.<\/p>\n

For example, let\u2019s say the colored cross-section is PC steel wire, and the section next to it is an injection hose.<\/p>\n

There are two hoses: one for injection and one for verification.<\/p>\n

Once you put the packer on, it ends up looking like this\u2014full of gaps.<\/p>\n

You fill it with Span Seal to prevent leaks.<\/p>\n

\"Span<\/p>\n

The orange part is the span seal.<\/p>\n

This is actually harder than you'd think.<\/p>\n

\"Span<\/p>\n

I'm working while teaching a young person, lol.<\/p>\n

This task is tedious and time-consuming, but it's an important part of the process.<\/p>\n

\"Span<\/p>\n

Be sure to install the Span Seal so that it runs around the entire circumference of one side.<\/p>\n

If the Span Seals stick together, there will be no gap.<\/p>\n

\"Span<\/p>\n

In the end, it will look like a ball like this.<\/p>\n

Please make sure the Span Seal is securely attached.<\/p>\n

Next, we'll finally put the packer on.<\/p>\n

 <\/p>\n

See you later.<\/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\/ground-anchor-packer-making-5\/#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":"2026-09-28 05:23:08","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\/01\/c0945c259c2aa3b4ae3644fe3ebd3d17.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/5779","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=5779"}],"version-history":[{"count":4,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/5779\/revisions"}],"predecessor-version":[{"id":63979,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/5779\/revisions\/63979"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/5653"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=5779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=5779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=5779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
