Yamanashi Prefecture Construction Example: Reinforcement Method for Existing Rockfall Protection Fences - No On-Site Processing Work Required!
All materials used are factory-made! This is a construction method that does not require processing work on-site.
Here is a case study of the "Stronger Method" implemented in Yamanashi Prefecture. As a result of the construction, the fence height increased from 2.0m to 3.0m, with a construction length of L = 60.0m. This method does not require the use of small heavy machinery, eliminating the need for tree cutting in the surrounding area. Additionally, there is no need for excavation of the slope or the use of concrete during construction, allowing for the reuse of existing structures. [Case Study] ■ Raised type (Fence height: H = 2.0 → 3.0m, Construction length: L = 60.0m) ■ Yamanashi Prefecture (Construction: Fiscal Year 2018) *For more details, please refer to the PDF document or feel free to contact us.
basic information
【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 loads that were previously supported by a single span in conventional methods are distributed across multiple spans. ■ The use of a high-strength wire mesh made from three uniquely developed steel wires prevents penetration of the mesh. ■ The energy absorption performance, which was limited to about 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.
