Examples of adopting reinforcement works for rockfall protection fences utilizing existing structures are published!
This document introduces examples of the "Stronger Method," a reinforcement technique for rockfall protection fences that utilizes existing structures. It includes a case from Fukushima Prefecture that addressed the request to raise the fence height due to rockfalls over the fence (from H=1.5m to 2.5m) with a raised type, as well as a case that dealt with the desire to reuse bent posts. In addition to detailed reasons for adoption, the document includes before-and-after photos, making it easy to compare the conditions before and after construction.

Company information
Until now, we have been cutting down trees on the slopes, excavating the ground to install concrete foundations, and then placing avalanche prevention shelves and rockfall protection shelves on top. However, the avalanche prevention shelves are ineffective against rockfalls, and the rockfall protection shelves are powerless against avalanches. The "triangular fence" developed and sold by our company effectively functions against both avalanches and rockfalls, and it does not require any excavation of the ground or concrete work, which could cause secondary disasters. It can be easily constructed using only lightweight materials, making it an environmentally friendly construction method suitable for the 21st century that does not compromise the landscape.
