Ballast free sleeperless track construction method for railway

摘要

The method involves the construction of the reinforced concrete trackbed with a slip-form paver. The holes for the bolts or anchors are then automatically marked out and drilled using accurate surveying equipment. The fixings are inserted into the holes and the rails put into place. The trackbed can be cast with discrete raised areas for supporting the rails. The bearing surfaces of the trackbed can be machined to the correct profile using accurate surveying methods separately or at the same time as the marking and drilling operations.
