Description

Technical Field

[0001] This utility model relates to the field of construction auxiliary accessories technology, specifically a protective device for assisting cable crossing. Background Technology

[0002] In natural gas pipeline monitoring, distributed fiber optic sensing technology is required. During construction, the fiber optic cable corresponding to the directly buried pipeline is laid at a 45° angle below the gas pipeline. At the pipeline splicing pit (approximately 12 meters apart), the sensing fiber optic cable is secured to the pipeline at intervals using plastic strapping. Due to the complexity of the construction site, different crossing methods are used when the fiber optic cable is laid alongside the pipeline, such as when the pipeline crosses highways, railways, or rivers. Protecting the fiber optic cable is essential in these situations.

[0003] In existing technologies, cable conduits are often used, such as flexible bushings that directly contact the outer surface of the cable, or prefabricated cable conduits in sections with steel wire guide ropes pre-inserted before traction. However, these methods offer relatively weak traction stability and cable protection. To address these issues, a protective device to assist cable crossing is proposed. Utility Model Content
