The invention discloses a preparation method of high-frequency vibration mixed concrete. The preparation method includes the steps: (1) raw material preparation; (2) no-load vibration; (3) primary feeding; (4) secondary feeding; (5) die-filling forming. According to the preparation method of the high-frequency vibration mixing concrete, by adjusting feeding modes and vibration modes, the number of50mum-below harmless holes and less harmless holes capable of improving concrete strength is increased to improve the working performance of the concrete, a water film on a gravel surface is destroyed, a concrete interface transition zone is optimized, the mechanical property of the concrete is improved by enhancing the interface transition zone, the 3-day compressive strength, the 28-day compressive strength and the 56-day compressive strength of the concrete can be improved by 27%, 34% and 28% according to the matching ratio of common mixed concrete, cement can be decreased by 15%-20% whenequal-strength concrete is prepared, and the preparation method has great market popularization and application values.
