Steam curing method for concrete pipe pile

The invention provides a steam curing method for a concrete pipe pile. The steam curing method comprises the following steps: standing the concrete pipe pile for 1-1.5 hours at a natural environment temperature; introducing steam into the steam-curing pool by a steam generator, and controlling the temperature rise speed in the steam-curing pool to be 15-30 DEG C/h; the temperature in the steam-curing pool is controlled to be 55-85 DEG C and maintained for 3-5 h; the cooling speed in the steam curing pool is controlled to be 15-25 DEG C/h until the temperature reaches the natural environment temperature; and collecting the condensate water in the constant-temperature stage steam-curing pool to a steam generator to be converted into steam again, or collecting the condensate water in the constant-temperature stage steam-curing pool and introducing the condensate water into another steam-curing pool in the heating stage. According to the steam curing method for the concrete pipe pile, the steam curing process con
