A new application of rockfall mitigation measures has been completed using Maccaferri’s Steelgrid HR System
Maccaferri Hellas provided a high strength Steelgrid HR System for a new road connecting the Cretan towns of Gazi and Krousonas, for rockfall protection and natural hazard mitigation.
On the Island of Crete, rockfall protection and natural hazard mitigation are key elements in the security and safety of roads, rail, mining operations and infrastructure networks. In many areas of the Aegean island a series of failures, including rockfalls, posed a very high risk to vehicles, especially along the provincial road connecting Gazi to Krousonas.
In the area near Heraklion, a project for the development of a new road between Gazi and the village of Krousonas is almost complete. During the works, the contractor in charge of the project, Domiki Kritis, advised that minor rock falls occurred, making the road below the slope dangerous for the passing vehicles.
The designer was already aware that the slopes had a high inclination and faced erosion problems during heavy rain when detachment of rocks is likely to occur, and recommended the implementation of secured drapery measures to prevent rockfall incidents.
Maccaferri Hellas provided a solution to create a secured drapery system in accordance with the minimum specifications of the project (150 kN of tensile strength), with its Steelgrid HR System.
The project was completed using Steelgrid HR 30, and other rockfall accessories including: 500/550 anchor bars (diameters of D25, D28, D32), HR links and HR plates.
