The construction technology and method of the Ferris wheel structure should be specified according to the specific structural form and site conditions. At present, the construction methods of the built Ferris wheel structure can be classified into the following three types. The rim steel structure of Ferris wheel is processed and assembled in sections in the factory. After transporting to the site, the rim is assembled into a whole, and then connected to the internal rigid truss support or flexible steel cable system, and finally the whole is hoisted into place. The British 'London Eye' adopts this construction method. The steel pipe truss of the wheel rim is divided into 3 sections and processed in the factory, and then transported to the site to assemble as a whole. Then the steel cable inside the wheel rim is installed and tensioned, and the prestress is introduced. Finally, the After the roulette structure and the supporting tower structure form an integral structure, hoisting is carried out. The ground assembly and overall hoisting method is conducive to the installation of the steel structure, and the installation accuracy is easy to ensure, but the scale and weight of the Ferris wheel are generally large, so a large construction site and strong lifting capacity are required. The center rotation installation method means that after the supporting tower and the axle are installed in place, the working platform is set up with the tower, or the Ferris wheel structure system is installed from the center to the periphery by the lifting system, and in some small and medium-sized Ferris wheel installation projects more applications. The vertical rotation installation method refers to the construction method in which the temporary rigid spokes are used to drive the segmented rims and steel cables to rotate and install after the supporting towers and axles are installed in place. The vertical rotation installation method is divided into one-side rotation installation method and two-side rotation installation method. It is suitable for the flexible Ferris wheel structure system that relies on steel cables to provide centripetal force. This method has been used in Tianjin Cihai Bridge Ferris wheel structure. The vertical rotation installation method can avoid a lot of high-altitude operations and has a lower risk; however, it requires a larger traction power system and a good braking system, especially the two-side rotation installation method requires special treatment for the center axle of the Ferris wheel.
