Adapting your ingenuity to local ground conditions creates a synergistic effect!
Hello, everyone. This is Enta. I recently wrapped up a rebar insertion project. Although we were a second-tier subcontractor on that job, the general contractor asked us to come up with a creative solution, so I proposed a 4-meter drainage borehole. Since the formwork dimensions are 300 mm square, the insertion length is 3.8 meters. (Within the formwork…
Basic Principles of Landslide Mitigation Measures (Part 1)
Hello, everyone. This is Enta. I’ve been in Ina City, Nagano Prefecture, for the past few days working on a rebar installation job. All the scaffolding clamps are adjustable, so the scaffolding is wobbly lol. Plus, the slope is almost vertical, so it feels like it’s going to tip backward lol. I’ll use a frame catcher to keep it stable lol. Anyway, the other day, T…
Measures to Prevent Cliff and Ground Collapses in Residential Homes | Stabilization Through Drainage Boring
Hello, everyone. This is Enta. The other day, there was significant damage in the Shizuoka area, and since I have many friends there, I’m very concerned. I received a message from a friend first thing this morning saying things are really tough, so I’d like to offer my sympathies. They also mentioned that it looks like it might rain again, so to everyone in mountainous areas or regions with many cliffs…
Effective Construction Methods for Disaster Sites and Sites at High Risk of Collapse or Requiring Immediate Action
Hello, everyone. This is Enta. Are you putting your creativity to work? I’ve been thinking lately about how rebar installation is carried out at disaster sites. Even during recovery efforts, there are many sites where parts of the structure have collapsed or caved in, aren’t there? In situations like that, the construction plan…
厚みのあるケーシングチューブを作ってみた|自作
皆さんこんにちは。 エンタです。 現場寒いですねw それはさておき、昨年からコア抜き用ドリルで施工しています現場の専用ケーシングを作って見ました。 有効長は280㎜で純正のケーシングチューブよりも肩肉2.5㎜は厚くしました。 純正よりも重厚…
Perforated Pipes Are Bonded Together with Glue | Drainage Worker
Hello, everyone. This is Enta. When performing drainage boring, do you apply adhesive to the PVC pipes? The perforated pipes used in drainage boring aren’t subjected to any particular stress; their role is simply to be buried in the ground and drain water away. For that reason, it’s true that many contractors tend to take this step lightly…
Casing Tubes for Core Drilling Are Not Suitable for Rock Formations | Limitations
Hello, everyone. This is Enta. It’s finally starting to get cold, isn’t it! It’s super tough out here on the job site, lol. We’re doing this kind of work inside a tunnel, but—maybe because of the bedrock—the casing tubes get completely worn out from the drill bit. This one’s brand new. We’ve also attached the drill bit…
Core Drilling for Drainage Boring | New Construction Method
Hello, everyone. This is Enta. I’ve been working on a new project lately. Well, it’s just a drainage job, but it’s in a very tight space. I’m using a core drill to drill through the concrete surface and then drill even deeper beyond that. The machine I’m using is strictly a core drill…
A Moment That Makes You Feel the Changing Times | The Sensibility of a Slope Engineer
Hello, everyone. This is Enta. The other day, I came across something called “remote witness” on Twitter! https://twitter.com/nitec_ct/status/1301706177365983232 I think this is a wonderful initiative…
