摘要：With the continuous improvement of bridge construction technology in our country, although the service life of the bridge has been greatly extended, the mechanical connection technology of steel bar in the technology is still in the stage of steel bar straight thread connection, which is nearly 30 years behind that of foreign countries. According to the development status and application requirements of bridge construction in China, it is of great practical significance to explore new technologies and methods to solve the problem of insufficient strength of straight thread connection of reinforcement. In this paper, the reliability of the straight thread reinforcement connection in the bridge foundation reinforcement cage connection technology is studied as the main breakthrough point, and the main problems encountered in the application of the straight thread reinforcement connection technology in the bridge reinforcement cage connection are analyzed.
