The utility model discloses an annular array type space prestressed concrete filled steel tube tower drum, which is characterized in that a certain number of auxiliary steel tubes are arranged in the steel tower drum in an annular array mode, the auxiliary steel tubes and an external steel drum form a cavity, and the space prestressed concrete filled steel tube is formed in the cavity through pressure pouring. The rigidity and the bearing capacity of the whole tower drum are enhanced through the steel pipe concrete, so that the steel consumption and the prefabrication cost of the whole tower drum are reduced. The annular array type space prestress concrete filled steel tube tower drum can be arranged into a plurality of sections in the height direction, the adjacent tower drum sections are connected through special-shaped flange plates and bolts, and the tower drum sections can be subjected to steel component welding, flange plate welding, concrete pouring and other prefabrication processes in a prefabricatio
