description The invention provides a post-buried steel plate reinforced prestressed structure and a construction method, and is characterized in that the post-buried steel plate reinforced prestressed structure is provided with a strip-shaped reinforced steel plate, an anchor rod, a matched nut, an anchor backing plate, MPC mortar and anchor sealing concrete; and the strip-shaped reinforced steel plate is anchored in a concrete body below the bottom plate of the box girder through an anchor rod. Wherein the transverse steel bars and the longitudinal steel bars are sequentially welded and bound at the bottom of the strip-shaped reinforced steel plate, so that the effects of stabilizing MPC mortar below the steel plate and improving the bending and shearing strength and rigidity of the strip-shaped reinforced steel plate are achieved. Wherein the strip-shaped reinforced steel plate is bonded and anchored in the beam bottom groove through the anchor rod and the MPC mortar, the jack jacking device is used for lifting the str
