Behind the Scenes of Sprayed Mortar and Concrete
Hello, everyone. This is Enta. I have a question about backfilling behind sprayed mortar and concrete surfaces. In some areas, soil and sand may have washed away, leaving voids. Do you think it’s absolutely necessary to backfill in those cases? When rain falls on the sprayed surface…
Basic Principles of Landslide Mitigation Measures (Part 4)
Hello, everyone. This is Enta. It’s gotten a lot colder all of a sudden, so I’ve started wearing a neck warmer! (Around my neck.) Starting next week, I plan to start wearing an electric-heated vest! But anyway, this is the final installment in our series on basic landslide prevention measures: “Cutting, Managing, and Stabbing.” Let’s review…
Basic Principles of Landslide Mitigation Measures (Part 3)
Hello, everyone. This is Enta. It’s already December!! There’s not much of the year left. Let’s make sure to avoid accidents at all costs! Don’t rush! Let’s do our jobs with our usual calm attitude. Getting flustered won’t do any of us any good, so let’s all be extra careful ^^ But anyway, speaking of landslides…
Basic Principles of Landslide Mitigation Measures (Part 2)
Hello, everyone. This is Enta. Basic Concepts of Landslide Mitigation Measures (Part 1) This is a continuation of my previous post. The brown area represents the mass of soil that is about to slide, and the orange area is the fill. Soil is placed at the edge of the mass that is about to slide to resist the force causing it to move. Simply put, when it tries to slide…
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…
Should the Injection Hose Be Removed When Inserting Rebar? | The True Meaning of Foreign Matter Contamination
Hello, everyone. This is Enta. When it comes to rebar insertion work, quite a few people say that the grout hose tends to come loose. Do you know why that happens? The people who say that are mostly laypeople who’ve outsourced construction management—lol. I don’t think many site supervisors say that. (Though there are a few, of course.) &nbs…
How to Measure Drilling Time and Guidelines | The Significance of Measurement Based on Soil Conditions
Hello, everyone. It’s Enta here. It’s kind of warm for December, isn’t it? lol But apparently, things are going to get crazy once the rain clears up this week! Make sure to switch to winter tires and bundle up by the first half of this week!! Anyway, I often time how long it takes to drill holes on site. Not that it really means much, though…
We strongly recommend conducting tests to measure circumferential friction resistance before starting this project!
Hello, everyone. This is Enta. The other day, we conducted a basic test for rebar insertion workers. This test checks whether the designed circumferential friction can be achieved, and since the formwork has already been installed, the test is being conducted within the formwork. Well, that’s just the way it is, so we’ll go ahead with the test…
What Does “Taking Responsibility” Mean in the Construction Industry? | The Essence of Leadership You Can’t Escape
Hello, everyone. This is Enta. The year is coming to a close. Now that we’re into December, it looks like our anchor team has one opening!! We’ll go anywhere!! We have a full set of equipment. By the way, we can also set up scaffolding, so we can drill from the scaffolding (anchors, rock bolts, water…
