[Stronger Method Adoption Example] Replacement of Bent Columns
The construction period is one day! The cost is less than half compared to base plate type or when demolishing and rebuilding.
Our company offers a rockfall protection fence reinforcement method called "Stronger Method," which allows for the reuse of bent posts by utilizing existing structures. First, remove the wire attachment fittings and cut the post at the base (250mm from the top). Then, attach the post connection member (only bolted). Next, install the raised post and reattach the removed wire attachment fittings. Compared to base plate systems or complete demolition and new installation, the cost is less than half, and the construction period can be completed in one day.

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.
