临江饱和淤泥质砂土地层围护桩施工技术

Linjiang saturated silt sand formation of retaining pile construction technology

结合工程地质水文情况和现场周边环境,对基坑围护桩在施工过程中出现的孔壁多次坍塌原因进行了分析和总结,后期通过采用砖渣换填、排水固结、水泥土+外加剂地质改良等措施的实施,确保了围护桩的工程质量,保障了基坑结构安全,取得了一定效果。

Based on the engineering geology, hydrological conditions and the surrounding environment, the foundation pit retaining pile in con-struction process of hole wall collapse reasons are analyzed and summarized for m a n y times, by adopting brick slag in late filling, water, soil, drainage consolidation ＋ geological improvement of the implementation of the measures such as admixture, ensure the engineering quality of re-taining piles, to ensure the safety of the structure of foundation pit, obtained the certain effect.
