The main tower is a circular single-column tower with a tower height of 118.6m m. Based on the site and the structural characteristics of the main tower, one tower crane is used as the vertical lifting equipment and one elevator is used as the personnel access, the lower tower column is constructed by turning over the formwork, and the middle and upper tower columns are constructed by hydraulic climbing formwork.
