<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
Now that the Cherry Blossom Festival is over, things have settled down completely.<\/p>\n
Things have calmed down a bit at work, but...<\/p>\n
I'm thinking, \"This is bad\" (lol)<\/p>\n
There are two scenes left over from last time involving Sakamaki that are really heartbreaking, but for some reason, I just can't seem to make any progress on them...<\/p>\n
I can't help but wonder, \"What's the deal with Sakamaki?\"<\/p>\n
We handle the shotcrete and drilling in-house, so there are no delays there, but the earthwork is causing delays.<\/p>\n
The same could be said for earthwork contractors, so I guess we\u2019re all in the same boat.<\/p>\n
Every time I do the Inversed Roll, I find myself thinking, \u201cI wish I could do this more efficiently.\u201d<\/p>\n
<\/p>\n
But that's beside the point.<\/p>\n
Here's the rod on the suspended core drill\u2014it's broken (lol).<\/p>\n

<\/p>\n
<\/p>\n
As you might expect, it breaks where the stress is greatest.<\/p>\n
As for why they break, it\u2019s either due to inadequate drilling techniques or metal fatigue in the rod itself.<\/p>\n
When a rod breaks due to metal fatigue, it usually breaks at the base.<\/p>\n
It often breaks at the junction between the sleeve and the threaded section, but this time it broke a little past the base.<\/p>\n
![\"Drill](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/04\/IMG_1943-600x800.jpg\")
<\/p>\n
Since the sleeve was brand new, it\u2019s highly unlikely to break.<\/p>\n
In conclusion, this means that the drilling was not done properly.<\/p>\n
<\/p>\n
This suspended drilling rig actually seems simple, but it\u2019s actually quite difficult.<\/p>\n
It's especially about controlling the force. Since it's air-powered, that's particularly important.<\/p>\n
Because the impact is so powerful, the more you push, the deeper it tends to dig in.<\/p>\n
Perhaps because of this, one of the features of this machine is that it allows you to drill holes to a certain extent even if you\u2019re not very skilled.<\/p>\n
<\/p>\n
A tip for drilling is not to press too hard.<\/strong><\/span><\/p>\n If the rod looks bent, pull it back a little.<\/strong><\/span><\/p>\n Do not practice empty swings.<\/strong><\/span><\/p>\n <\/p>\n Since we can't control the feed pressure, we'll check it visually.<\/p>\n It's best to drill the hole while keeping the rod straight and making sure it's not striking empty.<\/p>\n The key to determining whether it's a blank swing is whether the shank rod is being pushed down.<\/p>\n *If the tension wire is working properly, you can push it quite far.<\/p>\n <\/p>\n My youngest had surgery, so I'll turn a blind eye this time (lol)<\/p>\n New operators should carefully check the condition of the rod before drilling.<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.
