Positioning reinforcing mesh of prestressed duct and construction method of positioning reinforcing mesh

The invention discloses a positioning reinforcing mesh of a prestressed duct and a construction method of the positioning reinforcing mesh, and relates to the technical field of prefabrication construction of high-speed railway box girders. The positioning reinforcing mesh of the prestressed duct comprises two bottom plate positioning reinforcing steel bars parallel to a box girder bottom plate and two web plate positioning reinforcing steel bars parallel to a web plate; one end of the bottom plate positioning steel bar is fixedly connected with the bottom of the web positioning steel bar; a plurality of bottom plate prestressed duct meshes are formed between the two bottom plate positioning steel bars, and a plurality of web plate prestressed duct meshes are formed between the two web plate positioning steel bars. According to the construction method for positioning the reinforcing mesh based on the prestressed duct, the prestressed reinforcing mesh can be accurately positioned and firmly fixed, and the cons
