铁路隧道斜井进正洞挑顶施工技术研究

Research on Construction Technology of Roof Lifting in Inclined Shaft into Normal Hole of Railway Tunnel

文中以某铁路隧道施工项目为例,深入分析了斜井正进洞挑顶施工技术在实际应用中的注意事项与关键环节。研究发现,斜井正进洞挑顶施工技术在铁路隧道施工中具有良好的应用效果,能够减少正洞与斜井施工之间的交叉影响及施工量,有效提升施工作业环境的安全性与稳定性,控制施工成本。

This paper takes a railway tunnel construction project as an example to deeply analyze the precautions and key links in the practical application of inclined shaft forward hole lifting construction technology.Research has found that the construction technology of inclined shaft forward tunneling has a good application effect in railway tunnel construction,which can reduce the cross-influence and construction amount between the construction of positive hole and inclined shaft,improve the safety and stability of the construction environment,and help control the construction cost.
