Zusammenfassung:	The utility model discloses a right-hand and left-hand thread U-type clamp opposite-pulling and opposite-jacking rod for culvert or small bridge abutment body construction. The rod comprises a steel tube and thread sleeves welded to the two ends of the steel tube. A U-shaped clamp is welded to one end of each lead screw, and formwork holes into which formwork pins are inserted are reserved in the U-shaped clamps. The rod has the advantages of being simple in structure, convenient to use, capable of effectively reducing the number of steel tubes used for supporting a combined formwork, safe and reliable.
