<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
There will definitely come a time when you have to remove the temporary anchors lol (after the main construction work is finished).<\/p>\n
<\/p>\n
Extraction work is performed using either a crane or a backhoe (BH).<\/p>\n
However, there are still cases where it won't come out.<\/p>\n
<\/p>\n
The cause appears to be that the sheath surrounding the PC steel wire was torn for some reason, and<\/p>\n
This is a situation where cement slurry is flowing into that area.<\/p>\n
<\/p>\n
Once that happens, it's really hard to get out.<\/p>\n
It depends on how long it's been stuck, but since it doesn't usually stick very firmly, applying about 7t of force should be enough to pull it out. (From experience)<\/p>\n
<\/p>\n
But surprisingly, you can't really pull this out with a crane or a BH, can you? lol<\/p>\n
It\u2019s not that you can\u2019t remove it with a crane, but I don\u2019t recommend it because it\u2019s dangerous. (There\u2019s a risk of falling due to the recoil when it comes out.)<\/p>\n
If there's enough space behind you in the BH, it's not impossible to force it, but it's risky.<\/p>\n
<\/p>\n
In that case, you have no choice but to use a jack.<\/p>\n
However, by the time of extraction, the support beams had already been removed, and neither the steel base nor any reaction forces remained.<\/p>\n
In such cases, it is safer to install a reaction plate to absorb the reaction force while pulling the bolt out.<\/p>\n

<\/p>\n
There are structures behind us, so it\u2019s a very difficult site to work on.<\/p>\n
<\/p>\n
The installation angle is about 40 degrees, which is quite steep, but it comes out easily even when pulled straight.<\/p>\n
Once it starts moving, it comes out easily, so it's fine to use a crane to remove it.<\/p>\n
<\/p>\n
It is important to ensure that construction is carried out safely.<\/p>\n
There are still about two more steps to go, so I want to keep safety as my top priority throughout the construction process.<\/p>\n

See you later.<\/p>","protected":false},"excerpt":{"rendered":"
