The invention discloses a prestressed hollow combined structure tower drum based on steel pipe tenon-and-mortise joint connection and a construction method. The prestressed hollow combined structure tower drum comprises a drum body, the drum body is formed by assembling a plurality of drum sections in a segmented mode in the height direction, the adjacent drum sections are connected through steel pipe tenon-and-mortise joints, and the drum body is formed by connecting a plurality of hollow combined duct pieces through prestressed bent bolts in the annular direction. The hollow combined pipe piece comprises a hollow steel pipe, prestressed steel bars and a concrete shell. The steel pipe mortise and tenon joint comprises a concave tenon steel pipe, a convex tenon steel pipe, grouting materials and a PBL connecting piece welded to the outer wall of the convex tenon steel pipe. The advantages of a combined structure and a prestressed structure are exerted, the hollow steel pipes and the concrete are cooperatively
