Hyogo Prefecture Construction Case Study: Reinforcement Method for Existing Rockfall Protection Fences and Noise Control Measures During Demolition
This is a construction method that does not require measures for noise, dust, or high-alkali water treatment during concrete demolition.
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 = 69.0m. This method does not require the use of small heavy machinery, so there is no need to cut down surrounding trees. Additionally, excavation of slopes and the use of concrete are not necessary during construction, allowing for the reuse of existing structures. 【Case Study】 ■ Raised type (Fence height: H = 2.0 → 3.0m, Construction length: L = 69.0m) ■ Hyogo Prefecture (Construction: Fiscal Year 2018) *For more details, please refer to the PDF document or feel free to contact us.

![Reinforcing existing rockfall protection fences! Stronger Method [*with construction examples*]](https://image.www.ipros.com/public/catalog/image/01/a9a/329973/IPROS88553436931594286663.jpeg?w=120&h=170)
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.
