Description

Technical Field

[0001] The present application relates to the technical field of pipeline monitoring, and in particular to a pipeline structure. Background Art

[0002] Currently, in the field of transportation systems, pipelines are usually used to transport gas, liquid or fluids with solid particles. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] During the use of underground pipelines, aging or external force damage may cause damage or leakage. However, it is difficult to manually check and monitor the pipelines buried underground. Therefore, when burying the pipeline, a monitoring optical fiber that contacts the pipeline will be placed on the outer wall of the pipeline, and the monitoring optical fiber and the pipeline will be buried together.

[0004] However, when the detection optical fiber and the pipeline are buried together, buried objects such as soil may fall on the pipeline, causing the monitoring optical fiber that touches the pipeline to be separated from the pipeline, thereby affecting the detection of the monitoring optical fiber.
