The utility model discloses a pier body concrete curing structure which comprises a plastic film (2) surrounding the circumferential wall of a pier body (1), a fixing structure used for fixing the plastic film (2) and a dropper system. The dropper system comprises a water pipe and a water source connected to the water pipe. A control valve is arranged on the water pipe. The water source is fixed to the position, close to the top, of the pier body. According to the pier body concrete curing structure, the phenomenon that moisture is evaporated rapidly due to extremely high temperature or dry air is effectively avoided through the plastic film surrounding the pier body, and moisture is gathered on the plastic film so that concrete can be cured continuously, air between the plastic film and the pier body can be kept wet, water resources can be saved, the condition that water needs to be supplied to the water source multiple times in the curing process can be avoided, and the labor cost can be reduced. Especially in pier body construction in a water insufficient region, the pier body concrete curing structure is high in practicality and adaptability, and the whole section of the pier body is coated and cured continuously.
