| Abstract: | Because it is relatively difficult to construct double-wall steel cofferdam under water and the control process is complex, whether the steel cofferdam is adopted or not resting with engineering geology situation and technology condition. This paper introduces the double-wall steel cofferdam construction progress for water piers of Qingzhou-Shaxi super large bridge, including the manufacture and consolidation of the steel cofferdam, the cleaning and smoothing of the pier location, the floating and sinking of the steel cofferdam, the building of the steel terrace, and the sinking of the steel fence cylinder, etc. |
