Inoac Group Introduces Revolutionary Rockfall Prevention Technology

Inoac Juukan, a subsidiary of the leading Japanese chemical company Inoac Corporation, recently unveiled a pioneering rockfall prevention method known as the "Rockfall Source PUR Method". This innovative technology was developed in collaboration with Gifu University and Marusu Industry, marking a significant milestone in rockfall safety measures. The introduction of this method reflects Inoac's commitment to leveraging advanced materials and techniques to enhance public safety, especially in areas prone to natural disasters such as earthquakes and heavy rainfall.

Background of Development

For over four years, Inoac Juukan has been actively engaged in rockfall countermeasure projects across Japan, successfully implementing over six major initiatives, including assignments from the Ministry of Land, Infrastructure, Transport and Tourism. This extensive experience has provided the company with valuable insights and techniques that led to the development of this new method specifically focused on mitigating the sources of rockfalls.

The traditional rockfall prevention method known as "rope nets" involves covering loose rocks with grid-patterned wire ropes, which are then anchored to stabilize the slope. However, this approach has limitations, as gaps inevitably develop between the rocks. During earthquakes or excessive rainfall, these gaps can result in unstable conditions, undermining the effectiveness of the construction.

Overview of the New Technology

The newly developed "Rockfall Source PUR Method" takes a different approach by using site-applied polyurethane foam to fill the spaces between loose rocks, effectively binding them together to form a stable mass. This innovative technique not only prevents individual stones from shifting during seismic or hydro-geological events but also fundamentally reduces the overall risk of rockfalls.

The use of site-applied polyurethane foam allows for adaptability to various rock formations and configurations, enhancing its effectiveness compared to conventional methods.

Advantages of Site-Applied Polyurethane

The specific polyurethane product branded as "Foam Light W" offers several key benefits:

• - Shape Adaptability: This foam expands and hardens according to the shapes of gaps, making it capable of filling complex voids.
• - Stability Enhancement: By filling voids around unstable rocks, it helps to suppress their mobility during adverse conditions.
• - Long-term Reliability: The product exhibits low volume shrinkage, ensuring long-lasting stability over time.

With these features, the new method promises to deliver significantly improved rockfall prevention, especially in challenging environments previously deemed too difficult to manage with traditional techniques.

Future Steps for Implementation

Inoac Juukan is dedicated to expanding the application of the "Rockfall Source PUR Method" across multiple construction sites. By collaborating with Gifu University and Marusu Industry, the company plans to develop comprehensive manuals covering design and construction techniques to standardize quality control. This initiative aims to ensure that local construction firms across Japan can implement the method consistently and effectively, tailored to suit specific site conditions while prioritizing safety.

By working towards these goals, Inoac Juukan is not only promoting safer construction practices but also contributing to the broader dissemination of rockfall prevention techniques in Japan.
