Nanping cross-River Bridge in Fujian Province is a new type of bridge with suspension cable-cable-stayed cooperation system, which has the characteristics of high construction technology and complex construction process. In the face of the strong pressure to complete the superstructure construction in a short time, the diameter of the embedded pipe of the main cable anchor is too small, and the anchor head of the main cable can not pass through this difficult problem. In view of the existing problems, the paper introduces several solutions, such as grinding the inner diameter of the embedded pipe, developing a special reaming equipment, drawing and stretching the special specimen and replacing the anchor head of the main cable. By comparing with each other, an economical and convenient quick effect method is obtained, which can provide reference for dealing with similar situations in the future.
