| Abstract: | The closing installation conditions of steel pylon cross beams have direct influence on the global geometric shape and geometric precision of the pylon.The installation of such kind and the related interface hole boring are the two important links in the installation of overall pylon and the workmanship design and technical measures thereof are key to the installation quality control.In this paper,the principal workmanship design of closing installation and interface hole boring of the steel pylon cross beams of the 3rd Nanjing Changjiang River Bridge are briefly introduced and the technical measures that can ensure the installation precision are dealt with as well. |
