| Abstract: | 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. |
