The invention discloses a maintenance method for non-steam-curing of a large-pipe pile. According to the maintenance method, no steam curing is carried out on the formed and non-de-mold large-pipe pile, and steam curing is not included in the process. The maintenance method mainly comprises three stages that the first stage is after centrifugation, vibration and rolling molding are completed and before de-molding, and the maintenance of the first stage is maintained in a curing pool for heat preserving and maintaining; the second stage is after de-molding, water-rearing pond water rearing is carried out, and the second stage is moisture-preserving maintenance; and the third stage is after a pipe joint gets out of the water maintenance pool then the pipe joint is maintained, the maintenanceof the third stage is natural maintenance. On the basis, the invention further discloses a non-steam-curing of the large-pipe pile based on the maintenance method. According to the maintenance methodfor non-steam-curing of the large-pipe pile, the link of steam curing in the process of pile making of the large-pipe pile is avoided, the manufacturing difficulty of the large-pipe pile is greatly lowered, cost is reduced, energy is saved, meanwhile, the performance of the prepared large-pipe pile meets various requirements of specifications, the performance of the concrete of the large-pipe pile is effectively improved, and the method has a very wide application prospect.
