Shizuoka Prefecture construction case study: Reinforcement method for existing rockfall protection fences; no need to fell surrounding trees.
Reduce the impact on nearby residents! There is no need to cut down surrounding trees as small machinery is not used.
Here is a case study of the "Stronger Method" implemented in Shizuoka Prefecture. As a result of the construction, the fence height increased from 2.0m to 3.0m, with a construction length of L = 18.4m. This method does not require special tools or skilled workers for the installation of components. Additionally, all materials used are factory-made, eliminating the need for processing work on-site. [Case Study] ■ Raised type (Fence height: H = 2.0 → 3.0m, Construction length: L = 18.4m) ■ Shizuoka Prefecture (Construction: Fiscal Year 30) *For more details, please refer to the PDF materials or feel free to contact us.

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.
