DOUBLE CORROSION ground anchors are helping protect Jordan's first suspension bridge from earthquake damage.
About 140 anchors, prestressed to working loads of 1,000kN, aim to stabilise three of the pier foundations of the Wadi Abdoun Bridge against seismic forces.
The 110mm diameter anchors were installed in 150mm boreholes between 30m and 45m long by contractor Larsen & Toubro.
Grove Distributors supplied the double plastic protection that could fit in the tight boreholes.
Devon Mothersille, director of anchor specialist Geoserve Global, supervised tendon fabrication, encapsulation, grouting and preliminary site trials to ensure work complied with BS 8081:1989 and the new Eurocode for anchorages - EN 1537:2000.
