摘要
以新白广城际大窝岭下沉式暗挖隧道垂直出土施工为例,结合施工现场作业条件以及各类机器的选型和优缺点,简单论述了隧道工程垂直出土的各类方式。通过实践对比分析,总结了液压直顶式升降平台在下沉式暗挖隧道垂直出土中的操作方式和控制要点,为后续类似工程施工提供参考和借鉴。
Taking the vertical excavation of the sinking tunnel of Dabaiguang Intercity Dawoling as an example,combined with the construction site conditions and the selection,advantages and disadvantages of various types of machines,the various methods of vertical excavation of tunnel engineering are briefly discussed.Through practice comparison and analysis,the operation modes and control points of the hydraulic straight-top lifting platform in the vertical excavation of the submerged excavation tunnel are summarized,which provides reference and reference for the subsequent similar construction.
