When transversely putting and stretching, the longitudinal prestress of the high-speed rail plate is also put and stretched simultaneously, and the working process of putting and stretching is as follows: when the high-speed rail slab concrete reaches the tension releasing strength, the lifting mechanisms of the longitudinal tension releasing mechanisms act to adjust the height of the cross beam, and the rail slab steel mold enters the middle of the two longitudinal tension releasing mechanisms and is adjusted to a proper working position (namely, a tension releasing hand is horizontally concentric with a tension rod end nut); and the longitudinal regulator drives to act, so that the tension releasing hand of the longitudinal rotation tension releasing unit is contacted with the nut at the end part of the tension rod, the tension releasing motor is started, and the tension releasing hand is controlled to slowly and mechanically screw (the tension releasing motor stops after the set force value is reached). In the process, the tension releasing handle is ensured to be fully contacted with the nut at the end part of the tension rod, and then the tension releasing motor works according to the set force value and time.
And then the tensioning rod is screwed and withdrawn through the matching action of the tensioning hand and the nut at the end part of the tensioning rod until all the prestressed reinforcement force values approach 0, and the longitudinal prestress tensioning of the high-speed rail plate is finished.
