Wind power foundation based on replacing small wind power with large wind power and transformation method

According to the wind power foundation and the transformation method, an original old wind power foundation is in a circular truncated cone shape before and after transformation, embedded steel bars and a steel reinforcement framework are arranged on the inclined face of an old foundation abutment through embedded steel bar glue to enhance the overall collaboration of a new wind power foundation, and an old abutment annular groove is formed in the top face of the old foundation abutment; a flange ring is arranged in an annular groove of the old foundation abutment and filled with high-performance concrete, and the flange ring is connected with the old foundation abutment through a flange stud; concrete is poured on the upper portion of the old foundation abutment to form a new foundation, and after the concrete strength reaches a design value, the high-capacity tower drum, the new foundation and the flange ring are connected through anchor rods; and the cast-in-place piles are annularly arranged outside the n
