Hyogo Prefecture Construction Case Study: Reinforcement Method for Existing Rockfall Protection Fences - No Special Tools or Skilled Workers Required
No special tools or skilled workers are required. Utilize the existing protective fence to "increase the height of the fence."
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, with a construction length of L = 36.0m. The installation of the components for this method does not require special tools or skilled workers. 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 = 36.0m) ■ 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】 <Environmental Aspects> ■ No need for excavation of slopes or use of concrete during construction, allowing for the reuse of existing structures. ■ There is no need to demolish existing concrete retaining walls, eliminating fire prevention measures associated with cutting support beams, as well as noise, dust, and high alkalinity water treatment measures during concrete demolition. ■ No need for small heavy machinery, which means surrounding trees do not need to be cut down. ■ Reduced impact on nearby residents, such as traffic restrictions. *For more details, please refer to the PDF document 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.
