| Abstract: |
Although four suspension bridges have already been built in Korea, constructing the Yi Sun-sin Bridge is a great challenge not only because its main span length of 1545m is almost three times as long as the previous longest suspension bridge in Korea, but also because it is the first suspension bridge for which Korean engineers solely carried out all of the construction tasks, creating their own equipment and devices for the cable erection process as well. In this paper, several unique features pertaining to the cable erection procedures are introduced instead of the details of ordinary cable erection procedures, which are not very different from those of other long-span suspension bridges. An improved spinning wheel, a wire supply method for the spinning of extra- strands, and a band-hanger installation method are described. |
