AbstractThe floating platform as a positioning device has been used in a steel trestle construction with the function of the adjacent pile plane positioning and sinking orientationwhich greatly reduced measurement work on water. Meanwhile steel pipe pile was accurate location before pile driving by a simple fixture adjustment device installed on itcould shorten construction period and meet the construction requirements. The advantages of this method is the simple equipmentthe quick and appropriate method, and the higher positioning accuracy.
