<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
The other day, was that person an employee of the client\u2019s construction management company?<\/p>\n
I received some feedback regarding the injection.<\/p>\n
<\/p>\n
I'll explain this in more detail later.<\/p>\n
1. Drilling Complete<\/p>\n
2. Removing the inner rod<\/p>\n
3. Inserting an Anchor<\/p>\n
4. Injection of cement slurry through the injection hose (in-casing replacement injection)<\/p>\n
5. Check for Overflow<\/p>\n
6. Removing the outer casing (up to the anchored section)<\/p>\n
7.Pressure Injection<\/span><\/strong><\/span>\u3000Please point it out here<\/p>\n According to the Ground Anchor Association, the injection pressure ranges from 0.2 to 0.4 MPa.<\/p>\n However, in this case, the pressure did not reach 0.2 MPa. (In fact, it was only about 0.18 MPa.)<\/p>\n This is because it has come out of the casing and is no longer under pressure.<\/p>\n Since there's nothing we can do about it, I was about to wrap things up, but the older construction manager looked at me with a puzzled expression.<\/p>\n Since the level hasn't risen by 0.2, you're saying that it's standard practice to pump cement slurry from outside the casing.<\/p>\n <\/p>\n I've never done anything like that before, and there aren't any such documents or guidelines, are there?<\/p>\n As soon as I said that, he got really mad... lol<\/p>\n He came across as high-handed the whole time, so I guess I didn't phrase things very well either, but I don't know... lol<\/p>\n It's been a while since I've seen someone so bossy, lol.<\/p>\n <\/p>\n I certainly understand what you're saying.<\/p>\n However, once the cement has been thoroughly injected into the anchorage section, the free-length section is filled with cement.<\/p>\n Since this is Hokkaido, I don't have any specific data, so I can't be certain, but I seem to recall seeing somewhere that there's no need to be too concerned about pressure.<\/p>\n There are also papers that suggest the effect of pressure is minimal when it comes to clay layers and bedrock. (Not that it\u2019s relevant, but...)<\/p>\n <\/p>\n I make a whole batch of cement slurry, but depending on the location, waste can account for about 80 to 90 percent of it.<\/p>\n So when I said, \u201cI don\u2019t make that much cement slurry,\u201d they said it didn\u2019t matter.<\/p>\n So you're basically saying, \"Just make another one,\" lol<\/p>\n Oh, it's Professor High-Pressure! What a comment\u2014he doesn't give a second thought to on-site construction!<\/p>\n You can't just make a grout mixer in such small batches, so if you make too much and throw it away, you end up with a lot of trash, right?<\/p>\n It costs money, doesn't it? And it takes time, too, right? Is that really efficient?<\/p>\n That's what I'm thinking, but I won't say it\u2014even for a construction manager, that's pretty bad, isn't it? lol<\/p>\n The client is on equal footing with the winning bidder, right? (Oh, wait\u2014we\u2019re just a subcontractor, lol.)<\/p>\n I suppose construction management isn't really about money or efficiency. It's simply about whether the work is getting done.<\/p>\n So, is that why there are so many demanding teachers? Even though the nice ones are really, really nice, there\u2019s such a huge difference lol<\/p>\n <\/p>\n Even if the pressure doesn't rise, we remove a few casing sections afterward and perform a follow-up injection.<\/p>\n By that time, any water that had seeped out had turned into cement slurry.<\/p>\n But by that time, I had already gone home and wasn't there to watch the construction supervision anymore (since it was past 5:00 p.m.) lol<\/p>\n <\/p>\n Wow, I guess I ended up venting a bit.<\/p>\n If that construction manager comes by again, I'll try talking to him lol. I'm sure we both want to make this a great job site, right?<\/p>\n I wonder if we'll get along eventually?? lol<\/p>\n <\/p>\n See you later.<\/p>\n![\"Anchor](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/01\/59b0dc0ad9962c641d024f4f6ab3bf07.jpg\")
