Jig for Straight-Tensioning PC Steel Wire (Part 2) | Prototyping and Completion
Hello, everyone. It’s Enta here. Maybe it’s the flu? Either way, my nostrils are completely blocked lol. I just can’t seem to focus lolol. It’s like, “Aaaaaah.” Take care, everyone! But anyway… Since then, I’ve been looking at the shape of the anchor head…
Jig for Straight-Pulling PC Steel Wire (Part 1) | Construction
Hello, everyone. This is Enta. To be honest, I was actually planning to write today about how the Ministry of Land, Infrastructure, Transport and Tourism is open and transparent, while NEXCO is secretive. But after giving it some thought, I decided to write about the prestressed steel strands I mentioned the other day instead, lol. I figured I’d just end up writing about all of NEXCO’s shortcomings, so… lol…
Measures to Prevent Sand Ejection Caused by Groundwater Pressure in Anchor Construction (Part 3)
Hello, everyone. This is Enta. Today, starting in the afternoon, Mr. Itabashi from Toyotoku Industries (Machinery Repair) came by our place to do some repairs. He taught me how to use the gouging tool and how to perform detailed maintenance on the hydraulic unit! It’s a huge help. Though, I really could use a mechanic, lol. But anyway…
Measures to Prevent Sand Ejection Caused by Groundwater Pressure in Anchor Construction (Part 2)
Hello, everyone. This is Enta. All the construction projects I’m working on are getting pushed back, and there’s just nothing I can do about it lol. The general contractor doesn’t seem to care about the delays and just says, “You have to start on this date,” even though we’re behind schedule… That’s impossible, right? lol. I’m sure there are plenty of other construction companies thinking the same thing lol. Let’s be careful and take our time…
Measures to Prevent Sand Ejection Caused by Groundwater Pressure in Anchor Construction (Part 1)
Hello, everyone. This is Enta. The other day, I tried to see if I could carry a 133 double-pipe casing all by myself with one of our employees! Of course, this is how it turned out for me... But anyway, let’s talk about a common issue with temporary anchors: sand blowout caused by groundwater pressure. We really struggled with that at the site we were working on last week...
Soil Types Requiring Thorough In-Bore Testing | Drilling and Soil Classification
Hello, everyone. It’s Enta here. The other day, my Swivel cleaning adapter broke lol. Man, it’s such a beautiful autumn day~ lol. When things get that bad, take a breather and think carefully about your next move! I had ordered a spare, so I managed to get by this time. As expected, quasi…
Installing Load Cells in Anchor Assemblies | Continuous Monitoring of Tensile Force
Hello, everyone. This is Enta. Lately, I’ve been drilling nothing but anchors. Until now, our employees handled this, so I never really paid much attention to it, but now I’m starting to notice things I hadn’t before. The thing is, I hate that “craftsman’s intuition” thing, lol. I feel like I’m starting to understand that “intuition” a little bit…
The Condition of Anchor Heads in a Few Years | The Importance of Maintenance
Hello, everyone. This is Enta. I’m currently working on load relief at a construction site where work is underway. I’m relieving the load on an anchor that’s been under tension. I haven’t checked to see if it’s been retensioned afterward. What I want to point out is the rust on the head. It’s an anchor that’s been in place for several years now…
The Number One Machine Problem with Rotary Percussion | Frequent Breakdowns
Hello, everyone. This is Enta. It’s getting dark earlier these days. The other day, I had to work a little overtime, and before I knew it, the moon was out! It wasn’t even 6:00 yet. Hokkaido is already getting ready for winter. I hear it’s still hot in Honshu, and this temperature difference is pretty extreme. But anyway, regarding anchor drilling…
