Built -in optical fiber sensor lays structure

The utility model discloses a built -in optical fiber sensor lays structure relates to engineering structure and sensor field. It is to lay the structure, be provided with fluting (11) in concrete structure (10), laid optic fibre intelligence muscle (20) in 11 at the fluting, fix optic fibre intelligent muscle (20) in concrete structure (10) through briquetting (30) and bolt or screw (40). Layoutmethod is: 1. Make optic fibre intelligence muscle: optic fibre stick or fiber optic cable cable, 2. Slot on concrete structure and lay optic fibre intelligence muscle, 3. Exert little prestressing force to optic fibre intelligence muscle, 4. Fill the fluting. The utility model discloses the concrete structure who has laid optic fibre intelligence muscle has from monitoring and self -diagnostic function, advantages such as built -in optical fiber sensor has that stability is good, corrosion -resistant, anti -electromagnetic interference is strong, small, light in weight and precision height, be applicable to the const
