| description | The invention discloses a laying structure of Brillouin distributed optical fibers in a pipeline, which comprises a concrete pipe wall and a pipeline stainless steel outer lining, and a pipeline stainless steel inner lining is arranged on one side of the pipeline stainless steel outer lining facing the central line of the pipeline. Long-strip-shaped optical fiber distribution strip boxes are arranged in a cavity formed by the pipeline stainless steel outer lining and the pipeline stainless steel inner lining, and strain measurement optical fibers and temperature measurement optical fibers are placed in the two sets of optical fiber distribution strip boxes respectively. According to the laying structure of the Brillouin distributed optical fibers in the pipeline, eight sets of laying structures are annularly and symmetrically distributed along the outer wall of the stainless steel lining of the pipeline, the number of samples of data collection is increased, and the optical fiber containing cavity is connecte |
