In complex geological conditions, the rational cofferdam by selection according to the field geological conditions becomes the key technology of retaining and water stoppage in deep excavation. With the construction case of 22 pylon pier of Shuangyong bridge of Liuzhou, this paper introduced cofferdam construction technology with combined cofferdam by interlocking steel tube pile and reinforced concrete retaining pile in complex geological conditions.
