<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
Today, I went to the Iwakura Cherry Blossom Festival again to help out the Chamber of Commerce\u2014sort of? lol<\/p>\n
Well, it's still mostly just buds\u2014only about 20% in bloom\u2014so it's not much to look at at all.<\/p>\n
<\/p>\n
The peak of the cherry blossoms is expected to begin sometime this week or later.<\/span><\/strong>I think so. But the weather at the end of the month is...<\/p>\n But that's beside the point.<\/p>\n <\/p>\n How to Conduct Suitability Tests for Ground Anchor Construction<\/a><\/strong><\/p>\n This is the second installment, following up on the one from the other day lol<\/p>\n In the previous...<\/p>\n You can't get a perfect score, right!?<\/span><\/strong><\/span><\/p>\n Starting with,<\/p>\n So what are we going to do!?<\/span><\/strong><\/span><\/p>\n It's kind of like that, but I'll just get straight to the point, lol.<\/p>\n Manual operation yields the best data.<\/span><\/strong><\/p>\n Huh?!<\/span><\/strong><\/p>\n Huh?!<\/span><\/strong><\/p>\n What?!<\/span><\/strong><\/p>\n That's the vibe, right? lol<\/p>\n Measuring the hydraulic cylinder portion of a hydraulic jack with calipers<\/span><\/strong><\/span>That's what happens.<\/p>\n The dial gauge is already pointing in a completely ridiculous direction, but the calipers are straight! We're going to measure the extension of the cylinder indicated by this red arrow, so please have a digital caliper with a 1\/100 scale for 30 cm ready.<\/p>\n Also, if possible, it\u2019s more accurate to mark both the jack body and the jack head with a marker.<\/p>\n It's fine to measure just the cylinder.(It is important to always measure the same spot.)<\/strong><\/span><\/p>\n If we conduct a test using this measurement,Quite accurate<\/strong>That's it!<\/p>\n In my case, I follow the construction plan, which specifies that measurements should be taken with calipers.<\/p>\n *Based on experience, when installing anchors using a load-bearing plate in areas with insufficient soil bearing capacity, it is necessary to ensure that measurements can be taken on the load-bearing plate side using a dial gauge or calipers. <\/p>\n Back in the day, I just couldn\u2019t seem to get good data no matter what I did\u2014like when the dial gauge would go all wobbly during inspections, or when I\u2019d walk as quietly as possible on the scaffolding to take measurements, only to hear a loud thud right at the end. I went through a lot of trial and error when I was younger, but then it just occurred to me to start measuring the cylinders. (Maybe the heat was making me a little spacey? lol)<\/p>\n When I get back to the office and enter the data, I\u2019m like, \u201cHuh? Wait a minute\u2026 What\u2019s this?\u201d\u2014and it turns out to be great data!<\/p>\n Since then, that's pretty much all I've been doing, and here we are today\u2014the levels hardly ever drop, and the data smoothly stays within the upper and lower limits.<\/p>\n People say that to me sometimes.Won't the pressure plate sink?<\/span><\/span><\/p>\n Actually, there are times when it sinks, but,Segmentation<\/span><\/span>As such,<\/p>\n It hardly sinks at all.<\/p>\n If the value exceeds 600 kN, monitor the situation. If the boundary between the retaining structure and the natural ground is subsiding, also measure the amount of subsidence on the retaining structure side.<\/p>\n In the case of a pressure-receiving plate<\/strong><\/span><\/p>\n If the backfill is soil: Exercise caution for loads of 200 kN or more; in some cases, use a dial gauge on the load-bearing plate.<\/p>\n If the backing consists of bedrock, a cushion frame, sprayed mortar, etc.: If the load exceeds 600 kN, cracks may form and the structure may sink.<\/p>\n In the case of retaining walls<\/strong><\/span><\/p>\n It won't sink.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n As long as the ground underneath isn't just dirt, you don't really need to worry about it. (Just my experience as an entertainer, lol.)<\/p>\n And around 600 kN is a good rough estimate.<\/p>\n And let\u2019s go ahead and write that down in the construction plan with confidence! (This part is at your own risk, lol)<\/p>\n That said, there are still many people out there who insist, \u201cIt has to be this one!\u201d<\/p>\n That's fine, though.<\/p>\n However,Essence<\/span><\/strong>Please make your decision after determining where it is located.<\/p>\n The essence of this test is not the testing method itself, but rather verifying the quality of the anchors; therefore, as long as the quality is confirmed, any instrument will do.<\/p>\n I sometimes think that just saying \u201cit\u2019s no good\u201d is kind of nonsense these days, lol.<\/p>\n <\/p>\n Other than that, there is a product called the \"Digital Meter\" from FSC Fujiwara Industries Co., Ltd.<\/p>\n It's very convenient because it uses a wire and allows for digital measurements.<\/p>\n However, you do need to be careful about where you install it.<\/p>\n

\n(This is because an adjustment will be necessary if it sinks by a few centimeters.)<\/strong><\/p>\n\n\n
