Construction method and structure of concrete prestressed pier

The invention discloses a construction method and a structure of a concrete prestressed pier. The method comprises the steps of setting anchor blocks at the downstream of piers at a flood discharge outlet and connecting the anchor blocks with anchor cables which are poured in the piers and are arranged in the shape of a section. Since the anchor cables are poured in a directly buried way, anchor holes are not required to be reserved in pier concrete, the construction process can be simplified, and pier concrete pouring and structure integrity is improved; the construction process is greatly simplified; in order to prevent an anchor group effect from occurring at anchoring ends, a spatial distributed arrangement method of long and short alternate anchoring ends is adopted in both a vertical surface and a horizontal surface, the problem of stress concentration at the anchoring ends is effectively solved; at the same time, since an arc surface supporting arrangement method is adopted for stretching ends and anch
