Hyogo Construction Case Study: Railway Proximity Work - Reinforcement and Elevation of Existing Protective Fences
A case of railway proximity work where reinforcement and elevation of the existing protective fence were carried out!
Here is a case study of the "Stronger Method" implemented in Hyogo Prefecture. As a result of the construction, the fence height increased from 1.55m to 3.0m, with a construction length of L = 13.0m. This method distributes the load, which was previously supported by a single span in conventional methods, across multiple spans by connecting the tops of the posts with steel rods. Additionally, in areas where there are concerns about insufficient fence height, height-raising materials can be used to increase the fence height. [Case Study] ■ Height-raising reinforcement type (Fence height: H = 1.55 → 3.0m, Construction length: L = 13.0m) ■ Hyogo Prefecture (Construction: FY 2015, Railway proximity work) *For more details, please download the PDF or feel free to contact us.
basic information
【Construction Method Features】 ■ Performance - The upper and lower reinforcement brackets restrain the twisting of the support post and prevent buckling at the base of the post. - By connecting the top of the post with a steel rod, the load that was previously supported by a single span in conventional methods is distributed across multiple spans. ■ Workability - No special tools or skilled workers are required for the installation of components. - The components are lightweight, making installation simple. ■ Environmental Impact - No need for tree cutting in the surrounding area as small machinery is not used. - Reduced impact on local residents, such as traffic restrictions. *For more details, please download the PDF or feel free to contact us.

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.
