| Abstract: | Right Branch Main Bridge in Jiangxin Island of Nanjing Yangtze River Tunnel Project is a cable self-anchored suspension bridge. Its main cable adopted the PPWS construction method;for the technology, we optimized overall device for main cable erection. We used one-way reciprocating traction system to erect main cable, which improved efficiency. We also developed some strict measures for main cable traction, shaping and setting into the saddle, adjusting cable strand sagging and so on, which ensure the quality of main cable erection. |
