Abstract

The main bridge of the Danjiangkou Shuidu Second Bridge is a three-span continuous steel box girder arch bridge with a total length of (227.5+225+227.5) meters. The 20th pier of the bridge is located in the main channel of the Han River. During the construction period, the designed water depth is approximately 9.5 m, requiring the installation of steel cofferdams for underwater construction. Considering the design conditions, a comparative analysis was conducted, and the decision was made to use interlocking steel pipe piles for the cofferdam. The cofferdam is arranged in a rectangular shape with a plan dimension of 44.06 m × 18.52 m and a height of 21 m. It employs Φ820×14 steel pipe piles, with 4 layers of internal support and a 3 m thick C30 underwater concrete base. Through analysis and calculations under different working conditions, the results indicate that the cofferdam structure is safe and reliable. The construction’s critical techniques for the interlocking steel pipe pile cofferdam are detailed in the description.
