Combined anti-erosion semi-assembly type fan tower barrel

The combined anti-erosion semi-assembly type fan tower tube is composed of a top prefabricated tower tube and a semi-assembly type tower tube, and the semi-assembly type tower tube comprises an assembly steel tube, a concrete layer, a glass fiber plastic layer and a middle circular ring component. The assembly steel cylinder is of an assembly type structure and is formed by connecting and assembling a plurality of steel cylinder long components and steel cylinder short components through prestressed bolts, the bottom layer of the assembly steel cylinder is connected with a fan foundation, and after the assembly steel cylinder is assembled to a certain height, concrete layer pouring is conducted on the outer portion of the assembly steel cylinder so as to enhance the overall compressive strength of the tower cylinder. After the concrete layer is formed, an anti-corrosion glass fiber plastic layer wraps the outer side and is fixed through a middle circular ring component, a circular ring platform replacement pa
