[0029] Specifically, when the steam curing mechanism of the precast concrete pile is in use, the precast piles are successively put into the feeding frame 2, and then are successively transmitted to the rotating transmission device 4 through the guide plate 3, so that the precast piles rotate. At the same time, the steam generator 5 and the air extraction pump 6 are started, and the steam is transmitted into the annular pipe 8 through the air guide pipe 7, and the precast piles are sprayed and cured through the air jet heads 16. When the precast piles are discharged, the air cylinder 9 is started to move the cleaning brush 10 downward to clean the water droplets adhering to the surface of the precast piles.
