Zusammenfassung:	The utility model discloses a variable-diameter concrete precast pile, and belongs to the technical field of pipe pile structures. The variable-diameter concrete precast pile comprises a concrete precast pile body and a variable-diameter pile body, the concrete precast pile body is coaxially connected with the variable-diameter pile body, and the diameter of the variable-diameter pile body is smaller than that of the concrete precast pile body. The concrete precast pile is a hollow cylinder and is fixedly connected with the reducing pile body in a welded mode. The variable-diameter pile body comprises a variable-diameter part and a pile tip, and the variable-diameter part and the pile tip are an integrally-formed solid cylinder. The reducing part comprises a reducing upper part, a reducingmiddle part and a reducing lower part, the diameter of the reducing upper part is the same as that of the concrete precast pile, the diameter of the reducing lower part is smaller than that of the concrete precast pile, and
