Hyogo Prefecture Construction Case Study: Reinforcement Method for Existing Rockfall Protection Fences - Implementation of Fence Height Increase
Increase fence height using raised components! The materials are lightweight and installation is simple.
Here is a case study of the "Stronger Method" implemented in Hyogo Prefecture. As a result of the construction, the fence height increased from 2.0m to 3.0m. The construction length was L = 39.1m. This method allows for the existing rockfall protection fence to be utilized as is, enabling simple reinforcement and height increase without any special processing of the facility. [Case Study] ■ Height Increase Type (Fence Height: H = 2.0 → 3.0m, Construction Length: L = 39.1m) ■ Hyogo Prefecture (Construction: Fiscal Year 2018) *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Construction Method Features】 <Performance Aspect> ■ The upper and lower reinforcement brackets restrain the twisting of the posts and prevent buckling at the base of the posts. ■ By connecting the top of the posts with steel rods, the load that was previously supported by a single span in conventional methods is distributed across multiple spans. ■ The use of a high-strength wire mesh made from three uniquely developed steel wires prevents the mesh from being penetrated. ■ The energy absorption performance, which was limited to around 50KJ in conventional products, has been improved to approximately 120KJ. ■ In areas where the height of the fence is a concern, height-raising components are used to increase the fence height. *For more details, please refer to the PDF document 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.
