At this stage, the construction technology of prestressed concrete is widely used in Chinese bridge engineering construction, but the traditional construction technology of prestressed concrete is greatly affected by human factors, so it is difficult to fully guarantee the construction quality. With the rapid development of modern intelligent technology, the intelligent tension and intelligent grouting technology of prestressed concrete show the practical and economic advantages in the practical engineering application. This paper probes into the new technology of intelligent tension and intelligent grouting of prestressed concrete, makes clear the advantages and characteristics of the new technology, and provides ideas for strengthening the popularization and application of the new technology.
