The invention discloses a prestressed pipe pile. The prestressed pipe pile comprises pile bodies and constraint parts, wherein the constraint parts are removably installed on both ends of the pile bodies, and stiffening ribs are fixedly arranged on the outer circumferences of the constraint parts. According to the prestressed pipe pile, the constraint parts are arranged on the both ends of the pile bodies, so that the ends of the pile bodies are prevented from being damaged. The stiffening ribs are fixedly arranged on the outer circumferences of the constraint parts, so that the lateral resistance of the pile bodies is increased, the pulling resistant capability is increased, and especially in soft soil areas, the bearing capacity of the pipe pile is greatly increased by virtue of the stiffening ribs. In addition, the constraint parts can sleeve the ends of the two pile bodies so as to fixedly connect the two pile bodies, so that the pile bodies can be quickly spliced, and the bending resistant and shearing resistant capability and the shock resistant capability of the connecting positions between the pile bodies are increased.
