轻型井点降水联合强夯法加固吹填土地基

Technology of dynamic compaction with mildtype well point dewatering to dredger fill ground

结合某港口吹填土地基处理施工,进行了轻型井点降水联合强夯组合型地基处理工艺的试验研究。根据降水要求和夯点布置,对井点管的布置和施工方法进行探讨,最终采用了机械振动+水力洗孔联合成孔法。结果表明,对地下水位较高的砂性土地基,采用此法具有施工快、成本低、效果好等优点。

Combined with construction of dredger fill ground,we carried out the experimental study on dynamic compactionwith mildtype well point dewatering to dredger fill ground.According to the requirement of the well point dewatering anddynamic compaction layout,we studied the arrangement and construction method of the well point tube,and adopted themechanical vibration and hydraulic hole method.The results show that the method has advantages such as fast construction,lowcost and good effect for the sandy soil foundation with high groundwater level.
