The invention provides a concrete vibrating method for a large-span U-shaped thin-wall aqueduct. The concrete vibrating method includes the following steps: mounting multiple external-mold-attached vibrators on the external wall of an external mold of a groove forming machine, wherein mounting positions of the external-mold-attached vibrators correspond to positions of circular-arc sections of an aqueduct body of the large-span U-shaped thin-wall aqueduct; arranging at least one row of the external-mold-attached vibrators at the end head of the external mold; mounting multiple internal-mold-attached vibrators on the internal wall of an internal mold of the groove forming machine; vibrating the inside of a bin by flexible-shaft vibrating rods, and starting the attached vibrators at corresponding positions. In the concrete vibrating method, high-frequency attached vibrators are reasonably mounted and fixed on the external mold of the groove forming machine, the internal mold of the groove forming machine and a
