Rockfall Protection solution to mitigate the risk posed to people and infrastructure
Certain sections of the road in Claveria, Gingoog, Misamis Oriental are confined by cut-slopes along its perimeter, which posed a high risk to the people and infrastructure. A Rockfall protection system was used to mitigate the natural hazard.
The occurrence of rockfall, when not prevented, can cause significant damage to property, injuries, or even death. Certain sections of the road are confined by cut-slopes along its perimeter, which is unprotected and presents the following risks: (1) erosion of soil – leading to slippery roads, (2) dislodgement of rocks leading to rockfall events, and (3) localized slope failure from surficial instability. Even small rockfalls or debris flows can block infrastructure and have far-reaching economic effects beyond the immediate disruption.
Recognizing the need for a more reliable and effective rockfall protection system, Maccaferri Philippines proposed a solution that will mitigate the rockfall risk posed to people and infrastructure in Claveria, Gingoog, Misamis Oriental, Philippines.
Constructing a slope protection system along these road sections will promote the road’s resiliency and improve people’s lives and well-being. Erosion prevention and rockfall mitigation are key elements in the security and safety of infrastructure, buildings, or people. The slope protection system is intended to stabilize rock faces and soil slopes, reducing risks and irreversible damage to life and properties. It is designed to prevent soil erosion, rockfall, rockslides, debris flow, and shallow landslides, which is usually preceded by heavy rainfall and earthquake
The contractors, Pyramid Consolidated Builders & General Merchandise and BMDK Construction, and the consultant Department of Public Works & Highways, commenced work in June 2019 and completed the project in December 2019.
