管道悬索桥跨越绳索检测应用实例

Application Example of Pipeline Suspension Bridge Crossing Rope Detection

摘要: L管道巴河跨越为大型天然气管道悬索桥跨越，跨越的安全性决定着跨越管段的生产运行安全。现行标《油气管道架空部分及其附属设施维护保养规程》对跨越的绳索检测要求较为简单，尤其缺乏具体的技术要求及做法规定，不能完全满足跨越绳索检测的需要。我们通过对巴河跨越特点进行分析，结合公路桥梁绳索检测技术要求，采用先进技术手段对跨越绳索系统进行了全面检测，较好满足了现场的实际需要。本文总结分析了跨越绳索检测技术应用实践情况，可为下一步大型管道悬索跨越的绳索检测和管理提供有益的帮助，对实现管道完整性管理起到积极作用。

Abstract: The Bahe river crossing of L pipeline is a large natural gas pipeline suspension bridge. The safety of crossing determines the safety of production and operation of the crossing section. The current standard’ Maintenance Regulations for Overhead Parts of Oil and Gas Pipelines and Their Auxiliary Facilities’ has relatively simple requirements for the detection of crossing ropes, especially the lack of specific technical requirements and practice regulations, which cannot fully meet the needs of crossing rope detection. Through the analysis of the characteristics of the Bahe crossing, combined with the technical requirements of the highway bridge rope detection, we used advanced technical means to conduct a comprehensive detection of the crossing rope system, which better met the ac-tual needs of the site. This paper summarizes and analyzes the application practice of crossing rope detection technology, which can provide useful help for rope detection and management of large pipeline suspension crossing in the next step, and play a positive role in realizing pipeline integrity management.
