P-UHPC reinforcing device for reinforced concrete structure and construction method of P-UHPC reinforcing device

The invention relates to the field of building engineering structure reinforcement, and discloses a P-UHPC reinforcing device for a reinforced concrete structure and a construction method of the P-UHPC reinforcing device. The P-UHPC reinforcing device for the reinforced concrete structure comprises an UHPC reinforcing layer and connecting rebars which are fixed to the bottom of the reinforced concrete structure. One ends of the connecting rebars are fixed in the reinforced concrete structure, and the other ends of the connecting rebars are fixed in the UHPC reinforcing layer. A reinforcing layer rebar and a corrugated pipe are fixedly arranged in the UHPC reinforcing layer in the length direction of the UHPC reinforcing layer in a penetrating manner. A steel strand is arranged in the corrugated pipe in a penetrating manner. The steel strand extends out of the two ends of the corrugated pipe and anchored on the UHPC reinforcing layer. By the adoption of the reinforcing structure, the rigidity and bending resis
