摘要

IN CHALLENGING weather conditions, Danish contractor Per Aarsleff is installing its largest-profile - and one of its longest -combination steel pile-retaining walls for the extension to the container terminal at Port Muuga on the Gulf of Finland south coast, 17km east of the Estonian capital, Tallinn. Equipped with a fleet of specialist marine plant, the site team have been coping with freezing temperatures, strong winds and rough seas to accurately drive more than 420 tubular steel piles up to 1.67m in diameter and 45m long into the seabed. Approximately two-thirds of these piles, weighing up to 32t, will be linked together in combination with pairs of shorter, sheet-steel piles to form the main combiwall quay frontage and a section of retaining combiwall running parallel with, and alongside, the terminal's existing wharf.
