Maccaferri’s DT Mesh systems found to mitigate rockfall damages

Rockfall DT Mesh

Maccaferri’s wire mesh systems installed within tunnels worldwide prevent rockfall.

In December of 2015 Maccaferri provided two rockfall products—HEA Panel and Steelgrid MO for the rail-based public transport line in Sungai Buloh-Kajang. The project involved the construction of a rail-based transport network that would join with other light rail lines to form the transportation backbone of the Great Kuala Limpur/Klang Valley region. The project involved extensive tunneling works. Maccaferri was contracted to prevent rockfall and hazard-size debris from falling during the tunnel construction. Ultimately, the high strenght rockfall protection mesh systems were installed in less than three days.

Maccaferri’s Mesh systems are a core component of rockfall mitigation and protection from natural hazards. This project utilized Steelgrid and HEA Panels, which are part of a range of mesh systems from flexible drapery meshes to ultra-high strength steel cable panels offering very low strain performance. This range enables us to offer clients a tailored solution for the prevailing conditions, offering both technical and commerical efficiency.

Electrically powered transit systems can experience the effect of stray currents within metallic structures adjacent to the tracks. Recent research by TNO Delft focused on the possible interference of Maccaferri wire mesh gabions and Terramesh products as well as rockfall protection systems, with stray currents. The conclusions are interesting. The Technical Note in this is available from Maccaferri.
