This utility model discloses a screw-locked prestressed concrete square pile with a concealed lifting ring, relating to the field of building engineering technology. It includes a screw-locked prestressed concrete square pile, a concealed groove, and a telescopic lifting ring. The screw-locked prestressed concrete square pile has a concealed groove, within which a telescopic lifting ring is pre-embedded. The telescopic lifting ring comprises a hooked rod cylinder, a straight rod body, and an arc-shaped rod body.
