The invention discloses a concrete member mold and an application of the concrete member mold and relates to the technical field of concrete towers for wind power generation, large-scale prefabricated duct pieces and cement tubulation. The concrete member mold is used for solving the problem that prefabrication of a large-scale concrete member and turnover transportation of the concrete member mold are inconvenient. The concrete member mold comprises a lower mold plate, the upper surface of the lower mold plate is detachably connected with a plurality of side mold plates, first space is defined by the side mold plates detachably connected in sequence, the top of the first space is detachably connected with an upper mold plate, and a cavity of the concrete member mold is defined by the upper surface of the lower mold plate, the first space and the lower surface of the upper mold plate. The concrete member mold is used for manufacturing a base of a fan tower.
