The invention discloses equipment for insulating and curing pier column concrete in low-temperature seasons, solving the problem that the curing effects of the existing concrete in winter are not ideal. The curing equipment comprises an insulation device and a steam supply device, wherein the insulation device comprises an insulation cylinder arranged outside a pier column formwork in a sleeving manner; the steam supply device comprises a steam generator and a vent pipe; the steam generator is arranged outside the insulation cylinder; one end of the vent pipe is connected with the steam generator and the other end is sealed; the vent pipe is wound around the outer side of the pier column formwork; and a plurality of steam outlet holes facing the inner wall of the insulation cylinder are formed in the vent pipe. The curing equipment can ensure the temperature and humidity of the surface of the pier column concrete to be relatively uniform by being utilized to cure the pier column concrete for winter construction.
