Concrete solid pile

The invention provides a concrete solid pile, belonging to the technical field of buildings. The concrete solid pile solves the problems that an existing pile body has insufficient bearing strength, poor tension stability, lack of activity and self-hardening property in raw materials, incapability of realizing multiple process regulation and control indexes in manufacturing processes and the like. The concrete solid pile comprises a steel bar cage as a middle framework and a concrete solid poured onto the steel bar cage, wherein the concrete solid comprises cement, gravel, slag, sand and high-calcium fly ash, the content by specific weight of high-calcium fly ash is 30%-45%, and the calcium content in high-calcium fly ash is 10%-15%. According to the concrete solid pile, high-calcium fly ash and a corresponding modifier are added in the traditional component formula and are subjected to specific weight adjustment again, so that multiple process regulation and control indexes can be realized in the manufacturing processes of a whole base pile, the compressive strength and tension stability of the whole base pile are effectively strengthened by utilizing the characteristics of high-calcium fly ash, and the concrete solid pile further has the characteristics of activity of volcanic ash, small fineness, small weight of screen residue and the like.
