The invention discloses a fast mechanical connector structure for prestressed concrete pipe piles. The fast mechanical connector structure is characterized by comprising end plates which are connected mutually; the end plates are provided with inverted-T-shaped lock holes and prestressed anchor holes alternately; arc notches are formed in the outer edges of the end plates; protection covers and screw hole grooves are further connected to the end plates; the protection covers and the screw hole grooves are located in the sides, connected with the concrete pipe piles, of the end plates; the protection covers are arranged in a manner of corresponding to the inverted-T-shaped lock holes, and lock grooves are commonly formed by the protection covers and the inverted-T-shaped lock holes; the lock hole grooves correspond to the arc notches, and arc clamping grooves are commonly formed by the screw hole grooves and the arc notches; and the two corresponding end plates are connected through an I-shaped lock pin matched with the lock grooves and are fixed through an arc clamping plate connected at the positions of the arc clamping grooves in the edges of the end plates. The fast mechanical connector structure for the prestressed concrete pipe piles is simple in whole connector structure, economical, practical, safe, reliable and high in pulling resisting capability and shear resisting capability.
