摘要
随着我国城市进程的加快,城市轨道交通双模盾构模式转换技术得到有效应用,进一步提升轨道交通施工效率。当前隧道施工中常用的盾构机类型包含土压平衡盾构机和泥水平衡盾构机2种。其中土压平衡盾构机在稳定地层中较为常用,泥水式平衡盾构机在开挖面稳定的工程中较为常用。随着科学技术的发展双模式盾构施工技术使用率提高,因此需要对盾构模式的转化技术进行分析和研究,以便提升隧道掘进效率。该文主要结合深圳地铁8号线二期工添加梅沙站—小梅沙站区间模式转换施工项目案例,对EPB/TBM双模式盾构掘进施工技术的转换方法进行探究,旨在进一步提高轨道交通施工效果,促进工程掘进效率的提升,实现工程效益的最大化。
With the acceleration of urbanization process in China,the double-mode shield method conversion technology of urban rail transit has been effectively applied to further improve the efficiency of rail transit construction.The types of shield machines commonly used in tunnel construction include earth pressure balance shield machine and mud-water balance shield machine;the earth pressure balance shield machine is more commonly used in the stable stratum,and the mud balance shield machine is suitable for the excavation face stability project.With the development of science and technology,the utilization rate of double-mode shield construction technology is improved,so it is necessary to analyze and study the transformation technology of shield mode in order to improve the efficiency of tunnel tunneling.Taking the interval mode conversion project from Meisha Station to Xiaomeisha Station in the second phase of Shenzhen Metro Line 8 as a case,this paper probes into the conversion method of EPB/TBM double-mode shield tunneling construction technology,in order to further improve the rail transit construction effect,promote the tunneling efficiency and maximize the project benefit.
