天然气管道修复中非开挖技术的应用分析

Analysis on the Application of Non-Excavation Technology in Natural Gas Pipeline Repair

天然气管道埋设于城市道路地下,随着城市进程的加快,天然气管道数量越来越多,其修复工程量也越来越大。本文主要分析了翻转内衬法、插入法、缩径内衬法、折叠内衬法、原位喷涂法、挤出拉伸法在天然气管道中的具体应用。

Natural gas pipelines are buried underground in urban roads.With the acceleration of the urban process,the number of natural gas pipelines is increasing,and the amount of restoration projects is increasing.Specific applications of lining method,folding lining method,in-situ spraying method,and extrusion stretching method in natural gas pipelines are analyzed in this paper.
