摘要
通过对北京地铁14号线地质情况及工程难点的分析,调整注浆施工措施,采用深孔注浆的施工工艺进行地层超前加固施工,并克服了砂卵石地层注浆施工难题,对地层变形控制达到了良好的效果,保证了施工及地面建筑物安全,加快了工程进度,取得了十分显著的成效。
Based on the analysis on geological conditions and difficulties in Beijing Metro line 14,this paper introduces the adjusting of grouting technology. The deep grouting technology is adopted in prestrengthening of the soil to solve the grouting difficulties in sand and gravel strata. The deformation of soil is controlled and the safety of construction and buildings is ensured. Moreover the construction sequence is shortened.
