| Abstract: | In order to lift the first section of steel cofferdam for the 10th pier of Guanyinyan Yangtze River Bridge, the first section of steel cofferdam is piecewise assembled in the assembly site on board. At the same time, the hanger is installed in guided ship; six groups of single-layer reinforced Bailey beams are used as lifting beams. The first section of steel cofferdam is lifted using four-point lifting method, adjusting lifting hoist, eight-character cable and pocket cable at any time. Practice shows that the process is smooth, which can also save the cost. |
