CONTINUOUS CONCRETE SUPPORTS STRENGTHEN HONG KONG'S UNDERGROUND TRACKS

Settlement and lateral distortion of supports have always plagued conventional rail support systems. A method devised to solve these problems has been employed in the construction of 15.5 km of double track in Hong Kong's underground railway. With the system the "Pandrol" shoulders are cast precisely into the rail supporting plinth. The Pandrol shoulders are held in position by "Pandrol support bars" while the concrete sets. It is these support bars which form the key to the system. Two pairs of Pandrol shoulders are held in position on the Pandrol support bar by simple pins. The Pandrol support bars are clipped to modified conventional plinth forms. These forms are relatively inexpensive to fabricate and are made in short lengths. The method has three major advantages: the forms can accommodate normal railway curves; the forms can readily be transported down small shafts and accesses; and the system is flexible and can be assembled in short lengths on several headings or in long lengths as desired.
