The invention relates to a self-wedge-caulking tubular pile connector, which includes at least two hoop sections and self-wedging rings. The outer surfaces of the hoop sections are constructed as wedge surfaces, and the inner surfaces of the self-wedging rings are constructed to be wedge-caulked to each other when movement relative to the wedge surfaces of the hoop sections in the vertical direction exists. According to the self-wedge-caulking tubular pile connector, the structure is simple, the time and labor are saved during tubular pile connection through the connector, and connected tubular piles have the high uplift and shear capacity.
