浅谈水平旋喷技术在轨道交通富水软弱地层中的应用

摘要

在沿海地区城市轨道交通暗挖施工过程常遇到富水软弱地层，为做好暗挖施工过程中掌子面施工的堵水效果，采用水平旋喷桩进行掌子面上部水系的分割工作，保证开挖安全，对以后类似地层的施工起到借鉴和指导的作用。%In the coastal region, the weak watery stratum can often be encountered during underground excavation construction of urban rail transit, and in order to ensure the water-plug effect of tunnel face when constructing. The horizontal jet grouting pile will be used for segmenting the upper hydrographic net of tunnel face. This method ensures the safety of the excavation and provides reference and guidance for the construction of similar formation in the future.
