Cross-operational Railway Line Cover Girder Construction Technology and Engineering Application
In order to solve the technical problems of complex environmental construction difficulties such as crossing operating railway lines during bridge construction,this article takes the construction project of the elevated expressway at Dhaka Airport in Bangladesh as an example.In response to the problem of needing to ride existing operating railway lines for a long time,a new movable gantry auxiliary support system has been developed,successfully solving the problems of limited construction space and tight construction time for bridges crossing operating railway lines.
