| Zusammenfassung: | The invention relates to an application method of recyclable retard-bonded prestressed reinforcing steel. The retard-bonded prestressed reinforcing steel is prepared by wrapping a retard-bonded prestress steel stand with a plastic sheath added with a microwave absorber, and the prepared retard-bonded prestressed reinforcing steel is applied to the retard-bonded prestressed concrete structure of municipal roads, bridges and railroad bridges. The application method has the advantages that during structure demounting or retard-bonded prestressed reinforcing steel recycling, a microwave field is applied to an anchor head, the microwave absorber inside the retard-bonded prestressed reinforcing steel converts microwave energy into heat under the effect of the microwave field to allow the temperature of the plastic sheath in the anchor head area to rise and allow the plastic sheath to melt automatically, the anchor and the prestress steel strand are separated, and the steel strand loses tensile force and can be demo |
