摘要
北京地铁六号线二期工程起点至物资学院站区间左线泵站,采用冻结法加固土体。施工过程中对钻孔、冷冻设备和冻结帷幕等进行验收,土体开挖前和开挖过程中进行检查,冻结法施工历时9个月,土体加固效果良好,控制了地表沉降及对周围建筑物的影响。
Freezing method is adopted to reinforce the soil of left line pump room at interval between the starting station and Wuzi University Station of Beijing Subway Line 6 Phase Ⅱ project.Drilling and freezing equipments and frozen curtain are accepted during construction,and inspection is carried out before and during earth excavation.The freezing construction lasts 9 months.The soil is effectively reinforced,and ground settlement and influence on surrounding buildings are controlled.
