摘要
依托上海市陆翔路-祁连山路贯通工程,展示了该工程顶管段在下穿S20外环高速时采用的钢管幕超前支护施工技术。解决了路面变形及钢管幕顶进过程的姿态控制等关键技术,保证了S20外环高速的正常运行。所采用的钢管幕超前支护技术要求、施工工艺和监测结果可为类似工程提供参考。
Based on the connecting project of Luxiang Road and Qilianshan Road,the construction technology of steel pipes advance support in road tunnel engineering is demonstrated in this paper,when the pipe jacking section of the project passes through the S20 Outer-Ring Expressway.The key technologies such as the pavement deformation control and steel pipes attitude control during the jacking process are solved to ensure the normal traffic of S20 Outer-Ring Expressway.The technical requirements for the advanced support of steel pipe curtain,construction technology and monitoring results are the useful reference for similar projects.
