地下管线的综合治理是我国基础设施建设的重要组成部分,对于地下管线的修复更新,非开挖修复技术相对于开挖修复技术而言,具有环境影响小、施工周期短和综合成本低等特点。本文分析了目前国内外关于非开挖修复技术的相关研究,包括原位固化法、缠绕法、穿插法、碎管法、喷涂法、垫衬法、补丁法、套管法、机器人法和注浆法等,并且讨论了非开挖修复技术的优劣及在国内外的发展应用现状。通过对目前国内外非开挖修复技术的分析,为我国非开挖技术的发展提供了一些建议。
The comprehensive management of underground pipelines is a top priority in China's infrastructure construction. Compared to excavation repair technology, trenchless technology has the characteristics of small environmental impact, short construction period, and low comprehensive cost for the repair and renewal of underground pipelines. In this review, the current research on trenchless technology at home and abroad were analyzed, including in situ solidification method, winding method, insertion method, broken pipe method, spraying method, patch method, casing method, robot method, and grouting method. The advantages and disadvantages of trenchless technology and its development and application status at home and abroad were also discussed. Through the analysis of current domestic and international trenchless technology, some suggestions are provided for the development of trenchless technology in China.
