Self-sensing pipe cable combined structure

The utility model discloses a self-sensing pipe cable combined structure which comprises a self-sensing anchor cable body and surrounding rock for installing the self-sensing anchor cable body, a C-shaped steel pipe is connected to the outer surface of the surrounding rock in a penetrating and sliding mode, and the self-sensing anchor cable body penetrates through the C-shaped steel pipe and is fixedly connected with the interior of the surrounding rock. The outer surface of the C-shaped steel pipe is sequentially sleeved with a tray and a lock, and the tray is fixedly connected with the C-shaped steel pipe. According to the utility model, the optical fiber sensor with the diameter of only 0.1 mm is implanted into the anchor cable, so that the anchor cable has the dual functions of stress bearing and sensing. The problems that an externally-attached sensor is high in monitoring cost and prone to being damaged are fundamentally solved, the device is small in occupied space, the original structural form of a co
