摘　　要：城市地下排污渠道是城市中的重要基础设施。因针对老旧渠道的非开挖修复技术环境影响小,其将成为城市地下渠道维护修复中的重要方法。依托长沙市红旗渠排水改造项目,重点对红旗渠非开挖试验段4种工法(模筑法、喷射法、缠绕法、预制法)的实施情况进行深入分析研究,对4种工法的适用性能、技术性能及其经济性能等进行综合对比分析,并得出相关结论。Urban underground sewage channels are important infrastructure in cities.The non excavation repair technology for old channels will gradually become an important method in the maintenance and repair of urban underground channels due to its small environmental impact.Based on the drainage renovation project of the Hongqi Canal in Changsha City,an in-depth analysis and research have been conducted on the implementation of four construction methods(formwork method,spraying method,winding method,and prefabrication method)in the non excavation test section of the Red Flag Canal.The applicability,technical performance,and economic performance of the four construction methods have been comprehensively compared and analyzed,and relevant conclusions have been drawn.The research results can provide reference for the design and construction of urban old channel structure restoration.
