摘要
文章结合沈阳地铁浅埋暗挖法过街通道的工程特点,为确保地面车辆通行安全以及降低拱顶上方纵多管线沉降量,同时,保证暗挖工程能够安全、快速的通过,设计部门经过筛选采用洞内深孔注浆方案,即先进行钻孔定位,再钻进成孔,后退式注浆,然后,再封堵注浆孔转入下一孔位。该施工技术现场效果明显,可供类似工程借鉴。
This paper combined the engineering characteristics of the shallow tunneling method of Shenyang subway to ensure the safety of ground vehicles and reduce the settlement of vertical pipelines above the arch roof,while ensuring that the underground excavation project can pass safely and quickly.Internal deep hole grouting scheme,that is,the drilling is first positioned,then drilled into the hole,and the back grouting is performed,and then the grouting hole is blocked and transferred to the next hole.The construction technology has obvious effects on the scene and can be used for similar projects.
