Positioning device for prestressed pipe pile construction

The utility model discloses a positioning device for prestressed pipe pile construction, which comprises a first positioning mechanism, a first electric cylinder, a first movable arc-shaped clamping plate, a first fixed arc-shaped clamping plate, a first arc-shaped connecting plate and a second arc-shaped connecting plate, the bottom of the first arc-shaped connecting plate is fixedly connected with a first connecting vertical rod, and the bottom of the first connecting vertical rod is fixedly connected with a fourth arc-shaped connecting plate. The hoisted pipe pile needing to be connected is clamped and positioned through the second positioning mechanism, so that the bottom end of the pipe pile needing to be connected corresponds to the top end of the pre-buried pipe pile during welding, and the situation that the welding quality of the pre-buried pipe pile is affected due to deviation generated when the lower end of the pipe pile needing to be connected and the upper end of the pre-buried pipe pile are wel
