Prefabricated post-consolidation pier beam construction method and pier beam structure

The invention relates to a prefabricated post-consolidation pier beam construction method and a pier beam structure, and relates to the technical field of bridge construction. The pier beam construction method comprises the steps that firstly, a prefabricated pier is arranged on a pile foundation bearing platform, two prefabricated beams are symmetrically arranged at the top of the prefabricated pier, the positions of the two prefabricated beams are adjusted so that the two prefabricated beams can be at least partially placed at the top of the prefabricated pier, and a reserved gap not smaller than the preset length is reserved between the two prefabricated beams; and then the prefabricated beams placed above the top of the prefabricated pier are connected with the prefabricated pier, the first reserved steel bars at the adjacent ends of the two prefabricated beams are connected in the reserved gap, the second reserved steel bars at the top of the prefabricated pier are connected in the reserved gap, and fina
