Slot-type beam is a new structure with built-in cavities, and it is different from the upper prefabricated components such as the longitudinal beam of the high-piled wharf in terms of installation.In addition, it has no lower component to serve as the bearing surface and requires the pile foundation to be inserted into built-in cavities of the component.The slot-type beam has not been used in projects, and its installation is difficult.In view of the installation process of slot-type components, this paper develops a component installation operation platform and an integrated precise positioning device and studies the installation methods of different crane ships.In addition, the practical application of the first fully prefabricated high-piled wharf in China achieves excellent results and can provide a reference for similar projects.
