Method for connecting prefabricated cover beams through prestressed tendons and reinforcing steel bars

The invention relates to the technical field of urban rail traffic such as subway systems, urban fast rail systems, light rail systems, medium-low speed maglev traffic systems and straddle type monorail systems, in particular to a method for connecting prefabricated cover beams through prestressed tendons and reinforcing steel bars. First preformed holes corresponding to the prestressed tendons extending out of the top face of the pier column and second preformed holes corresponding to the common steel bars extending out of the top face of the pier column are pre-buried in the prefabricated cover beam, and grouting materials are poured into the first preformed holes and the second preformed holes. Prefabricated assembly of the prefabricated cover beam and the pier column is achieved, the common steel bars and the prestressed tendons are arranged to be connected with the prefabricated cover beam, structural stress is met, and the durability of a joint of the pier column and the prefabricated cover beam is impr
