Device for keeping perpendicularity of pipe pile in deep and thick fill stratum

The utility model provides a device for keeping perpendicularity of a tubular pile in a deep and thick fill stratum, which comprises a baffle and a protective cylinder arranged at the bottom of the baffle, a circular opening for the tubular pile to penetrate through is formed in the center of the baffle, and a fixing ring which is used for stabilizing the tubular pile and shares the same vertical axis center with the protective cylinder is arranged in the protective cylinder. Four hydraulic pushing devices distributed on the periphery of the baffle are symmetrically arranged on the baffle and used for balancing the pipe pile when the pipe pile is pressed downwards. The device is simple in structure and reasonable in design, the device is placed in a hole, the pipe pile penetrates through the device to ensure the perpendicularity when the pipe pile descends in a deep and thick soil filling layer, the situation that the pipe pile does not meet the construction requirement due to inclination is avoided, and use
