Pipe pile mechanical connection joint

The utility model provides a mechanical connection joint for pipe piles, which is used for connecting two superposed concrete pipe piles and comprises two annular end plates and a hoop. The two annular end plates are used for being fixed to the ends of the concrete pipe pile. The hoops are arranged along the peripheries of the two annular end plates; the hoop comprises at least two arc-shaped plates and connecting plates with the corresponding number, first grooves are formed in the connecting plates, the width of the bottom of each first groove is larger than that of a notch of the first groove, protrusions are arranged on the outer surfaces of the two ends of each arc-shaped plate respectively, and the protrusions of the two adjacent arc-shaped plates are inserted into the first grooves side by side to connect the two arc-shaped plates into a whole. Compared with the prior art, the hoop is adopted for connecting the pipe pile, the good mechanical property of a hoop type connector is fully utilized, the over
