Key Technology of Construction Control of the Middle Pylon of Taizhou Bridge

Abstract:

The Taizhou Yangtze river bridge is a suspension bridge with three pylons and two 1080m long navigation spans. The middle pylon with height 191.5m is made of steel. The general construction procedure of the middle steel pylon is briefly introduced. Construction control of the pylon is carried out during the whole process of the construction. The control concept is extended to the manufacture stage besides the installation stage. The manufacturing alignment errors are strictly controlled in precast process of the segments in factory, and the alignment error is identified and predicted precisely during the installation stage. The adjusting joints are adopted to adjust the accumulated errors, which ensure that the steel pylon alignment could satisfy the as-built precision requirements.
