The utility model discloses a pipe pile spreading and buffering device. The pipe pile spreading and buffering device comprises a support frame and two supporting devices. The two supporting devices are symmetrically arranged on the left side and the right side of the support frame respectively. Each supporting device comprises a base, a supporting cam, a rotating device and a power drive device. The supporting cams are connected with the power drive devices through the rotating devices. The left side and the right side of the support frame stretch across the two supporting cams respectively, and the power drive devices are installed on the bases. The pipe pile spreading and buffering device is reasonable in structure and capable of bearing impact of more than 60 tons and avoiding large impact in the process of placing a pipe mould onto a spreading trolley, thereby being capable of avoiding impact on a metering sensor.
