FRP-UHPC shell reinforcing prefabricated part and preparation method thereof

The invention discloses an FRP-UHPC (Fiber Reinforced Polymer-Ultra High Performance Concrete) shell reinforcing prefabricated part and a preparation method thereof. The prefabricated part comprises a first UHPC shell and a second UHPC shell, grouting sleeves and annular FRP stirrups which are arranged in a staggered mode are arranged in the two shells, when the two shells are assembled, one end of the FRP stirrup in the first UHPC shell penetrates through the edge embedding face to be inserted into the grouting sleeve in the second UHPC shell to be fixed, and the other end of the FRP stirrup in the second UHPC shell penetrates through the edge embedding face to be fixed. And meanwhile, one end of the FRP stirrup in the second UHPC shell penetrates through the edge embedding surface to be inserted into the grouting sleeve in the first UHPC shell to be fixed, and then grouting anchoring is performed after the two shells are embedded through grouting holes in the outer side walls of the two shells, so that the
