Aseismic Upgrade of an Existing Railway Embankment by Double Sheet Pile and Tubular Pile Walls

The East Japan Railway Company, which owns and operates major long distance and commuting lines in and north of Tokyo, is upgrading existing track embankments per the new aseismic guidelines so they will be resilient to withstand strong earthquakes in the future. Some of the embankment retrofit projects are installing double sheet pile walls with tie-wires or tie-rods that connect them to minimize the possibility of liquefaction of the embankments. The construction next to live railway tracks, especially those on embankments, requires extremely low vibration and allows for no ground settlement as part of special attention to railway safety. In addition, the work space is often quite limited due to steep slopes of the embankment, neighboring structures, overhead catenary lines, and/or overcrossing bridges with minimal distance from the tracks. The press-in piling method has been successfully adopted to drive sheet piles and tubular piles to meet these requirements for pile installation within a few meters of the rail company’s busy commuter lines.
