The invention relates to a moving method for a T beam of a prefabricated beam factory, in particular to a construction method for a horizontal moving beam of a double-track trolley. The invention adopts two beam-moving trolleys to move beams in a horizontal direction along the track. Jacks are arranged the beam-moving trolleys, the jacks have an automatic lifting function, firstly, the trolleys are moved directly below the T beam in a longitudinal beam storage area, the jacks are started to hold the T beam, so that the T beam breaks away from an original beam storage pedestal. After the reinforcement and stability, the trolleys pull the T beam to move along a horizontal track to a horizontal beam storage area. Then the jacks are depressurized, the T beam is in place, and the trolleys return empty. The construction method realizes the horizontal beam moving, overcomes the problems of the T-beam stability during the cross construction and the beam moving process of the longitudinal andhorizontal tracks, fully utilizes the site width of a precast beam factory, and improves the beam storage capacity of the precast beam factory.
