Abstract:
Installation of master cables in suspension pipeline bridge involves complicated processes, high quality requirements, and less availability of technologies and facilities. Accordingly, the precast parallel wire strand (PPWS) method is improved to innovate the installation of master cables depending on structural features of suspension pipeline bridge, referring to the installation process of master cables in suspension bridges for highways and railways. Moreover, process flows and design principles for relevant equipment and facilities related to the innovative PPWS-based technology are clarified, and key technical points in its implementation are stated. The results show that the improved PPWS is applicable to installation of master cables in suspension pipeline bridges, with higher efficiency and quality to certain extent. This method can also be deployed for installation of master cables for other suspension bridges with single span or multiple spans.
