Modular construction system for building elevated railway track, uses prefabricated concrete arches, longitudinal support beams and track elements installed by crane

摘要

Building of the elevated railway track (1) starts with the installation of the prefabricated concrete arches (2) at regular intervals. Longitudinal steel support beams (3) are then installed on top of the arches. A crane (5) is then used to place the concrete track elements (4) on top of the beams. A each element is secured, the crane moves forwards on the track to install the next element.
