The invention discloses a detaching-free movable formwork for a concrete-passing continuous beam. When the distance between two pier bodies exceeds the length of the movable formwork, a concrete box girder is built between the two piers by using a hanging basket, then a track is laid on the concrete box girder, a longitudinal movement propelling device acts, and a driving cross beam uses a hangingbracket to suspend the movable formwork located behind the concrete box girder to move forwards along the length direction of the concrete box girder till the movable formwork moves to the front endof the concrete box girder. The reverse transportation of the movable formwork is realized, after the movable formwork moves in place, a hydraulic jack acts to drive the cross beam to move up and downrelative to the concrete box girder, the elevation is adjusted, then the movable formwork can be used for continuously constructing the standard-span concrete box girder, the removal, transportationand reinstallation of the mo
