Mass concrete construction method

The invention relates to the technical field of concrete construction, and particularly discloses a mass concrete construction method which comprises the following steps: S1, preparing mass concrete with low hydration heat, low shrinkage and high durability; s2, concrete is transported, poured and vibrated, during concrete pouring, during construction in winter, before pumping, pipe moistening is conducted through hot water and mortar with the temperature not lower than 15 DEG C, and during construction in summer, a concrete pumping pipeline is wrapped with a reflective heat preservation material, so that the temperature difference between the interior and the exterior of the pump pipe ranges from 1 DEG C to 1.5 DEG C; the mold entering temperature of mass concrete in a summer high-temperature environment is controlled to be lower than 30 DEG C, and the mold entering temperature in a winter cold environment is controlled to be higher than 10 DEG C; s3, concrete curing, wherein the temperature difference betwe
