The invention provides a suspension type high-frequency vibration method and a special device. The technical problem that reactive powder concrete needs to be vibrated and leveled repeatedly is mainly solved through the suspension type high-frequency vibration method and the special device. According to the technical scheme, the suspension type high-frequency vibration method and the special device are characterized in that vibration leveling walking devices (28) are installed at the two ends of a vibration truss (25) correspondingly; a suspension type high-frequency vibration device body (22) is installed on the lower portion of the vibration truss (25) and comprises two or more vibration flat plates (222); and a vibration flat plate oblique angle adjusting device (224) is installed on each elastic suspension device (223) in a matched mode, so that an 1-70 degree included angle is formed between each vibration flat plate (222) and the horizontal plane. According to the suspension type high-frequency vibration method and the special device, due to the fact that manual operation is not needed, the efficiency is greatly improved, the leveling effect is better, the leveling degree is also greatly improved, and automatic continuous operation is achieved. The suspension type high-frequency vibration method and the special device are mainly used in the field of reactive powder concrete production construction and the like.
