For the low control accuracy of double-wall steel cofferdam sinking plane position, through scheme comparison, this paper made the thought of island-style guiding device, accordingly designed an inside guiding device for the control of plane position in cofferdam sinking process, and implemented it. Taking the double-wall steel cofferdam of Kongli Huaihe River Bridge in Anhui Huainan for example, this paper discussed the process principles, structure form and processing elements of the device, effectively solved the low control accuracy problem through the practice, improved the position accuracy of double-walled steel cofferdam, and achieved good economic and social benefits. It provided reference for similar projects.
