Anchoring method for grouting and anchoring reinforcing steel bar in corrugated pipe to anchor precast segmental beam and parking area stiffening strut
The invention provides an anchoring method for grouting and anchoring a reinforcing steel bar in a corrugated pipe to anchor a precast segmental beam and a parking area stiffening strut. The method comprises the following steps of pre-embedding the corrugated pipe in the segmental beam precasting process; inserting the anchored reinforcing steel bar into the corrugated pipe after the segmental beam is demolded; and casting the stiffening strut after the anchored reinforcing steel bar and the corrugated pipe are grouted and anchored. According to the invention, through applying the reinforcing steel bar anchoring method to a special structure in bridge precast construction, the traditional production process and template do not need to be changed; it is only required to pre-embed the corrugated pipe in the continuously production process; the process is simple while performing the construction of the stiffening strut in the later stage; the anchoring performance is reliable due to the use of non-shrinkage and high-strength grouting materials; and the construction progress is furthest accelerated on the premise of ensuring the construction quality.
