As shown in fig. 3, in another aspect of the present invention, there is provided a construction method of a cable anchoring device for installing the cable anchoring device, the method including the steps of:

In the step 4, the method for arranging the bolt on the second cylinder includes: the bolt at the first limiting position is disassembled and is arranged at the second limiting position, and the second limiting position is the position where the movable plate can move furthest under the action of the elastic force of the disc spring.
When the stay cable is in a normal state, the pulling force borne by the stay cable is the same as the elastic force of the disc spring, and the two forces are mutually offset, so that the disc spring still keeps the maximum compression state; when the inhaul cable bears larger pulling force, the position of the movable plate is unchanged relative to the initial state and is still at the first limit position, but the larger pulling force is transmitted to the first limit structure, namely the annular bulge, and the annular bulge and the outer cylinder have certain rigidity and can offset the larger pulling force borne by the inhaul cable, wherein the thickness of the annular bulge can be adjusted to adjust the pulling force value borne by the annular bulge; when the guy cable is loosened, the movable plate is pushed to move under the action of the elastic force of the disc spring to offset the looseness of the guy cable; the movable plate can freely move between a first limit position and a second limit position so as to deal with the looseness of the stay cables with different degrees; in order to avoid the unlimited movement of the moving plate, the second limit position is set as the maximum moving stroke of the moving plate.
The limiting structure used in the second limiting position can be a bolt used in the first limiting position, after the anchoring device is installed, the bolt in the first limiting position needs to be detached (at this time, the pulling force applied to the moving plate by the inhaul cable is the same as the elastic force applied to the moving plate by the disc spring), and the second limiting position needs a corresponding limiting structure.
