[0002] The pull rod plays a vital role in the field of road construction, especially in the field of road construction with a larger width. It effectively disperses the load on the road structure through its tensioning effect, reduces stress concentration caused by traffic load, and avoids horizontal displacement of the road precast block.

[0003] The pull rod is usually installed between the longitudinal joints of the road or the joints of the precast road blocks, and the rod body is horizontally inserted into the inside of the road main concrete on both sides of the joint. In the traditional construction process, except for part of the construction method using precast concrete blocks, the pull rod needs to be installed at the preset position and fixed according to the pre-calculated results before the concrete is poured. The pull rod is installed, and then the concrete is poured. This scheme is more efficient than the construction scheme of drilling holes in the corresponding pull rod installation position after the concrete is formed.
