Thermal pipeline with optical cable

The invention provides a thermal pipeline with an optical cable. By laying the optical cable in an external structure layer of the thermal pipeline in the whole process, external signal change, such as abnormal temperature or structure disturbance, can be sensed by virtue of optical fibers in the optical cable, and sensors are continuously distributed on the thermal pipeline in the whole process,thereby facilitating monitoring of the thermal pipeline with no blind zone in the whole process in use; the safe and high-quality operation of a heat pipeline network is improved. The thermal pipelineis characterized by comprising a main body of the thermal pipeline, and the external structure layer wrapping the peripheral surface of the main body of the thermal pipeline; and the external structure layer is internally provided with the optical cable. 种带光缆的热力管道，通过将光缆全程敷设于热力管道的外部结构层中，能够借助于光缆中光纤对外部信号变化的敏感，例如温度异常或结构扰动等，在热力管道上形成全程连续的传感器分布，从而有利于对使用中的热力管道实现全程无盲区监测，促进热力管网的安全运行和高质量运行，其特征在于，包括热力管道主体和包覆所述热力管道主体外周面的外部结构层，所述外部结构层中
