The fear of being unemployed lol<\/p>\n
That's the tricky part about public works projects, isn't it...<\/p>\n
\n
But that's beside the point.<\/p>\n
In ground anchors and rebar insertion work (rock bolting)
\n What on earth is a \"packer\"?!<\/p>\n
Even after injecting cement slurry, the conditions inside the borehole are poor,(A condition characterized by extensive voids caused by cracks and the accumulation of rock fragments)<\/strong><\/span><\/p>\n If the grout does not rise above the design level (inside the casing or borehole wall) and cannot be verified,<\/p>\n Using a packer,A product that prevents grout from leaking into cracks and voids<\/span><\/strong><\/span>That's it.<\/p>\n To assess the on-site conditions, if ground anchors are being drilled in a water-filled trench,<\/p>\n If no drilling fluid comes out, the grout will definitely not rise.<\/p>\n It can be pretty hard to tell with \"Air,\" but I think you'll generally be able to tell with \"Ope.\"<\/p>\n For example, the drill suddenly dropped 30 cm in one go, or there are many limestone caves in the area. 1. Temporarily halt work at the site, consult with the local government, and adjust the injection volume or modify the design 2. After consulting with the local government, we will make a design change to use a packer.<\/strong><\/span><\/p>\n 3. Unauthorized use of the packer. (Corporate Efforts)<\/strong><\/span><\/p>\n 4. Use the packer creatively.<\/strong><\/span><\/p>\n 1. First of all, that\u2019s not going to happen. Government agencies almost never change the dosage.<\/strong><\/span><\/p>\n If the design and the actual site don't match up, it'll be hard to come up with excuses during the audit lol<\/strong><\/span><\/p>\n We will not make any changes to the design calculations themselves (such as soil properties or strata). (Consistency with the design)<\/strong><\/span><\/p>\n If we change the stability calculations in the design, everything will change, so, 2. There are plenty of them. This is the safest option. You can install it simply by adding a packer to the design. 3. There are many such cases. Ultimately, when you consider issues related to the construction schedule and the risks involved in halting construction, 4. There are plenty of them.<\/strong><\/span><\/p>\n However, regarding point 2, can\u2019t the government agency find a creative way to make it work\u2014as if it were some kind of magic phrase? <\/p>\n That's all for now!<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.

\n That does make things a bit more of a hassle for the contractors, too.
\n (If it's \"Bring on the design changes!\", then we can do it!)<\/strong><\/span><\/p>\n
\n However, since the packer is surprisingly expensive, they might be reluctant to buy it.
\n If the additional work is 30% or less, there's a good chance it will be approved.<\/strong><\/span><\/p>\n
\n There are times when it\u2019s better to just leave it at the company\u2019s own efforts.
\n (However, submitting it to the government office in the form of a meeting log will make a better impression.)<\/strong><\/span><\/p>\n
\n <\/strong><\/span>If someone says that, it's possible lol<\/strong><\/span><\/p>\n
