Device for preventing dislocation of PHC pipe pile joint

The utility model relates to the technical field of pipe piles, in particular to a device for preventing dislocation of a PHC pipe pile connector. The device for preventing dislocation of the PHC pipe pile connector comprises hinge supports, limiting pieces and clamping pieces, semicircular rings are hinged to the tops and the bottoms of the two hinge supports, limiting grooves are axially formed in end openings of the semicircular rings, and the limiting pieces used for connecting the adjacent semicircular rings end to end to form a complete circular ring are fixedly installed at the ends of the semicircular rings. The limiting grooves are movably matched with the limiting grooves; the limiting piece for connecting the adjacent semicircular rings end to end to form a complete circular ring is fixedly mounted at the other end of the semicircular ring and is movably matched with the limiting groove; the clamping piece used for limiting movement of the PHC pipe pile and assisting butt joint is fixedly installed
