    The Ministry of Public Works and Public Housing through PJN 2 PPK 2.5 West Java carried out the construction of a national road that connects Bandung and South Cianjur. The purpose of road construction is to establish better traffic and to improve the economy in the southern part of West Java. A rockfall hazard was discovered along Bts. Bandung\/Cianjur \u2013 Naringgul \u2013 Cidaun Road due to weathered conditions of the rock slope that endangers the lives of the road users. Thus, a solution to prevent the hazard was needed and should be obtained by considering the impact of the rockfall potential. The key points to be considered in choosing the suitable solution and\/or material for this project include: – The forces of falling rock – The capacity of the material to dissipate the forces – Impacted zones The designated material had to withstand an estimated rockfall of 10 tons mass from 30m height and 4m2 of volume. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    To comply with the requirements of enduring the estimated falling rocks, Maccaferri Indonesia provided a rockfall barrier (RB 3000) to dissipate the energy of falling rocks of up to 3,000 kJ with 6 meters height and 25 meters total length. The barrier is made of strong ring nets that provide the bulk of the strength combined with double-twisted steel wires with smaller openings that enables it to catch smaller rocks as well. The ring nets and steel wires are coated with Galfan (ZnAl5% – Class A) for corrosion protection. To withstand the large energy impact, the system is held in place with an array of steel posts, T-FAST (Rope Anchor), and concrete foundations. A special brake system is also put in place to absorb most of the energy from the rockfall. Maccaferri Indonesia also provided comprehensive services starting from technical recommendation, manufacture and supply materials, and Product Assistance during the construction stage. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
