摘　　要：3S模块技术是采用透明PVC塑料模块在原有管道内拼装成内衬管后,通过对产生的缝隙实施灌浆形成复合管结构的修复方法。该技术具有施工时间灵活的优势,且复合管结构强度高、抗腐蚀性强,并可目视灌浆情况,以有效保证施工质量,适用于多种施工环境尤其是无法实施临排措施的大型管道。结合华阳路-光复西路过苏州河倒虹管非开挖内衬修复项目,对比分析特大口径排水管道在非开挖内衬修复过程中不同施工技术的特点,阐述3S模块技术修复施工中的质量关键控制点,总结施工过程中需注意的工程难点和技术措施,并展望3S模块技术在特大管道修复方面的应用前景。3S module technology is a repair method in which a transparent PVC plastic module is assembled into a lining pipe in the original pipe,and a composite pipe structure is formed by grouting the gaps generated.The technology has the advantages of flexible construction time,high structural strength of composite pipe,strong corrosion resistance and visual grouting,which can effectively ensure the construction quality,and is suitable for a variety of construction environments,especially large pipelines that cannot implement temporary drainage measures.Combined with the trenchless lining repair project of Huayang Road–West Guangfu Road inverted siphon crossing Suzhou River,the characteristics of different construction technologies in the trenchless lining repair of extra-large diameter drainage pipelines are compared and analyzed.The key control points of quality in the repair construction of 3S module technology are expounded.The engineering difficulties and technical measures for attention in the construction process are summarized.And the application prospect of 3S module technology in the repair of extra-large pipelines is expected.
