Hello, everyone. This is Enta. The other day, during a main contractor’s safety inspection at a job site, I was called out on a safety harness issue.

These Lolips don’t really break very often…

Slope Stabilization Work That Cannot Be Seen | Underground Section

Hello, everyone. This is Enta. I went out to check on the site the other day.

Review of the Toyo Koken Slope Walker NT-4R | Weight and Installation Challenges

Hello, everyone. This is Enta. I tried out the slope walker made by Toyo Koken that I introduced a while back! Here it is. You drive the anchor into the ground to set up the slope walker. Then, you create a wire line using single-wall pipes. The wire gets caught in weird places…

Guidelines for Rock Crushing | Risk Management in Slope Construction

Hello, everyone. This is Enta. The other day, I was putting together a roster of Vietnamese workers. There were so many names that I couldn’t tell them apart. Names are tricky, aren’t they? Even in Japan, people with so-called “flashy names” seem to have a hard time—we’ve reached a point where some who face difficulties in daily life are even changing their names…
