Part of the Inanda Dam project included the development of the road infrastructure to access the dam. The geometry of the landscape required fill embankments for the new road surfaces along the mountainous terrain. The remote location of the site added to the costs of importing materials and transportation of plant onto site. The predominant in-situ material consisted of a decomposed granite with a density of 2000kg\/m\u00b3 making it suitable for the embankment fill. To minimise this fill, a near vertical retaining structure was required along the new embankment. The consultant, Bradford Conning, approached Maccaferri Africa\/African Gabions for assistance with the design of four retaining walls with average heights of 3m. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

The initial designs by the consultant entailed a conventional mass gravity gabion structure with a large volume of rock – a quantity exceeding that available on site. The Terramesh\u2122 System, consisting of a gabion mesh cage with a continuous mesh tail as reinforcement, was chosen as it required less rock. The final solution consisted of a 7m high Terramesh\u2122 structure with a 2m foundation depth. The mesh tails extended 4 metres into the earth embankment behind the Terramesh\u2122 facing. The Terramesh\u2122 front face consisted of horizontal steps of 220mm and vertical steps of 500mm up to a height of 2m followed by steps of 1,0m. The smaller units at the base reduced bulging and enhanced the stability of the structure. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
