Abstract: The continuous beam tension and grouting make the prestressed steel bar and the concrete member form a whole, and form an integral anchor. Grouting isolates the prestressed steel bars from the air and keeps the steel bars in the alkaline environment of the concrete grout to prevent oxidation and corrosion. The tensioning and grouting process is complicated, and it has strict requirements on tension, time, strength, sequence, continuity, etc. It is a key process of continuous beam construction, which is worthy of in-depth study and discussion.
