摘　　要：安全施工是城市轨道工程建设中的重点内容,在城市轨道隧道盾构施工中,由于盾构在穿越城市污水管时存在一定的风险,为保证施工安全顺利进行,需要对污水管进行迁改保护。文章以成都轨道交通17号线一期工程温泉大道站~明光站盾构段施工为例,对城市轨道隧道盾构区间污水管改移顶管安全施工方案与技术措施进行具体的探讨,以供参考。Safe construction is the key content of urban rail project construction.In the shield construction of urban rail tunnel,there are certain risks when the shield passes through the urban sewage pipe.In order to ensure the safe and smooth construction,the sewage pipe needs to be relocated and protected.Taking the construction of shield section from Wenquan Avenue Station to Mingguang Station of Chengdu Rail Transit Line 17 Phase I Project as an example,this paper discusses the safety construction scheme and technical measures for replacing sewage pipe with pipe jacking in shield section of urban rail tunnel for reference.
