The invention discloses a sealing structure for a vacuum compaction road roller, and belongs to the technical field of engineering machinery. The sealing structure comprises an upper steel plate, a rubber plate, a steel wheel, a side steel plate, a rubber backing plate, a crawler device and a side supporting plate, a hydraulic motor drives a driving sprocket through a belt, the driving sprocket is matched with a crawler chain to drive a crawler rubber belt, an onboard hydraulic circuit supplies oil for the hydraulic motor, synchronization of the linear speed of the crawler rubber belt and the linear speed of the steel wheel is ensured through a control device, a guide sprocket can function in guiding, a dragging wheel supports the crawler rubber belt, and the lower portion of the dragging wheel and a road surface are compressed, so that tightness is kept. The crawler device is skillfully used, friction between rubber and the road surface is transformed into friction between the rubber and the steel plate, friction force is remarkably reduced, and the road surface cannot be damaged. The simple sealing structure meets vacuum degree requirements of vacuum compaction.
