MSE wall rebuild

摘要

Herzog's MPM rebuilds a mechanically stabilized earth wall on Denver Regional Transportation District's light rail tracks in two weeks.rnIn the early hours of Jan. 17, 2009, 18 freight cars carrying molten sulfur derailed on a main line running beside the Regional Transportation District's light rail tracks in Littleton, Colo. Not only did the derailment damage two of three main lines, but also the mechanically stabilized earth wall supporting one of RTD's two light rail tracks, located six feet above the main line tracks.rnHerzog Contracting Corp. sent two of its MPMs to aid in the clean up and begin repairs. One came from just north of Denver, while the second was rerouted to Littleton on its way to Iowa. According to Herzog, the machines had experience working in tight quarters and performing trackway wash-out work, but never before had they been used to perform wall replacement.
