The production and operation process of prestressed concrete components of prestressing method is relatively simple, without leaving holes, threading bundles, grouting, sealing anchors, etc., saving materials such as corrugated pipes, anchors, anchor steel bars and pipe slurry, and the production efficiency is high. Since the prestressing prestressing method adopts distributed bundles, the prestressed steel bundles are dispersed inside the main beam, so they need to be cut one by one when they are released, but the construction efficiency is low, and when cutting, the stress release may cause ejection at the end of the steel strand, which poses a safety hazard.
