摘　　要：城市管线复杂交错,管网分布范围广,为保证新建工程的顺利进行,需要做好施工范围内既有管线的迁改工作,管线迁改应征得产权管理单位的同意确认,施工前采用物探、人工挖槽等方法核查管线的走向、用途、管径、基底高程等,编制管线迁改方案,为了确保沟槽周边管线安全、沟槽内施工人员安全,采用6m钢板桩+钢支撑形式对管线沟槽进行支护,从基坑土方开挖、管道施工、管沟回填方面,保证管线迁改工程的安全质量。In order to ensure the smooth progress of the new construction project,it is necessary to carry out the relocation of the existing pipelines within the construction scope,before construction,geophysical prospecting and manual trenching are used to check pipeline trend,usage,pipeline diameter,basement elevation,etc.,in order to ensure the safety of the pipeline around the trench and the safety of the constructors in the trench,the 6m steel sheet pile+steel support is adopted to support the pipeline trench,to ensure the safety and quality of the pipeline relocation project..
