The invention belongs to the technical field of power transmission equipment and discloses a circular concrete pole production line and a production process thereof. The design is scientific and reasonable, calibration control over a steel bar framework is conducted through pre-pretension, the dimension accuracy of the steel bar framework of a concrete pole is ensured, and thus the high quality and stability of the concrete pole are ensured; concrete distribution is conducted automatically through a concrete pumping unit and a weight metering system, concrete distribution accuracy is ensured,waste is avoided, and manpower and material resources are saved; besides, a great number of automatic production facilities are adopted, the degree of automation of the concrete pole production line is greatly increased, the labor intensity of workers is relieved, the safety risk is reduced, and the production efficiency and production quality are improved; and furthermore, by arranging a plurality of production lines for poles of different lengths, accurate production is conducted, resource waste is avoided, energy saving and environment friendliness are achieved, and the production cost is reduced.
