Track structure of the rapid track transit

摘要

A guideway structure for high-speed track-bound transportation composed of two or more than two girder-segments. The structure of the guideway is characteristic of: At the intermediate positions on the girder top and the girder bottom of the connecting ends of the said girder-segments are all disposed the pre-embedded steel elements and some anchoring nails used for ensuring the pre-embedded steel elements to be reliably connected with the concrete of girder-segments, after the relevant connecting ends of the two adjacent girder-segments are placed closely, they may be connected together to form a two-span quasi-continuous girder by tightening a plurality of bolts through their respective through hole on the connecting elements and on the pre-embedded elements.
