In 2008, an incident of debris flow with approximately 4,000m of mud soil had flowed down hill to highway of Sections 62-4 to 62-8 along Simpang Pulai Road (Laluan FT185) in Lojing, Gua Musang, Kelantan. The height from toe to the debris source was about 260m, with slope gradient ranged from 20\u00b0to 35\u00b0. It was anticipated that the risk of debris flow re-occurrence at the same location was high and estimated to be 5,000m\u00b3 in volume. Hence, the Authority was looking for engineered barriers to be installed along the anticipated flow path to retain or retard the debris flow, in order to minimize the risk of debris reaching the highway.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Maccaferri had proposed flexible debris flow barriers with energy capacity of 3,000kJ to be constructed at 3 locations along the flow path. At the final point, a gabion embankment was constructed at the slope toe. The barriers which consist of high strength yet flexible steel cables netting were connected with series of specially designed energy dissipaters to absorb the forces during big impact. In general, the flexible barriers will allow high velocity hydraulic flow (mud slurry) to pass through the netting, while catching the harmful larger-mass objects. Nonetheless, it will also act as check dams to reduce velocity of the fast flowing mud slurry. The final volume of the mud slurry that go through the flexible barriers will be onstructed by the gabion embankment at the slope toe and channeled to the drain. The length of the flexible barrie at each location was about 30m across the flow path, with maximum height of 5.5m post. It took about 3 months to construct the flexible barriers at the 3 locations.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
