As a type of prestressed system, the anchorage system of rolled threaded bar is an important factor in the application of prestressed concrete engineering. In this paper, the anchorage system of prestressed rolled thread reinforcement has the characteristics of large diameter, high strength, low relaxation and small shrinkage. The successful application of φ75 and φ85 roller threaded steel bars and their anchoring systems in Hong Kong-Zhuhai-Macao Bridge and Nanning Yinghua Bridge shows that the excellent performance of the roller threaded copper bar anchoring system has played a good role in promoting the application of bridge prefabrication segment-assembly technology to form pipelining lines and accelerate the construction progress.
