摘要
结合济南地铁闫千户车站项目的实际施工情况,分析了粉质粘土地层和降水难点,通过在粉质粘土地层采用降水回灌技术,提高基坑水位平衡,从而有效控制基坑施工监测的数据,为基坑开挖安全提供强有力数据及技术保障,降低了基坑周边建筑物沉降等施工风险,该施工方法取得了良好的经济效益。
Combined with the actual construction of Ji'nan Metro Yanqianhu Station project,the silty clay stratum and precipitation difficulties are analyzed.By using precipitation and recharge technique in the silty clay stratum,the water level balance of the foundation pit is improved,and the foundation pit construction monitoring data is effectively controlled,which provides strong data and technical support for the safety of foundation pit excavation,and reduces the construction risk of buildings surrounding the foundation pit and other construction risks.This construction method has achieved good economic benefits.
