Disclosed are a buried heat storage tube and a manufacturing method thereof, wherein the heat storage tube comprises flanged piping (1, 2, 3), a supporting and positioning frame (4), a heat transfer medium arranged in the flanged piping (1, 2, 3), a heat storage medium, a heat storage cavity (5), a heat storage cavity plugging end (6) and a thermal insulation housing (7). The heat storage tube uses a blend of paraffin wax and glycerine as the heat storage medium, and the heat storage temperature is 40-100°C. The heat storage and heat exchange properties of the heat storage medium are stable, and the production techniques are simple; using asphalt as a thermal insulation and anti-corrosive material enables the anti-corrosion property of underground tubes to be improved and the service life to be increased. The heat storage tube is suitable for the fields of heat exchange, heat storage of liquids, and heat storage of gases at temperatures of less than 100°C.
