Dredger fill foundation treatment construction method
The invention provides a dredger fill foundation treatment construction method. The dredger fill foundation treatment construction method comprises the steps that surface layer surface soil is removed through an excavator to the water level elevation, a bulldozer rolls a site to generate liquefaction water burst, bucket soil of the excavator is inserted into soil to be vibrated, rushed and liquefied, the bulldozer rolls and extrudes the soil to enable excess pore water to be drained, and a submersible pump is used for pumping the soil away from the site to accelerate drainage consolidation; and aired dry soil is backfilled and compacted in a layered manner to form a hard shell layer, the hard shell layer prevents underground water from returning upwards, and high bearing force and low compressibility are kept. The dredger fill foundation treatment construction method has the beneficial effects that the operation method is simple, the bearing force is obviously improved, the consumed time and the construction period are short, and cost is low.
本发明提供一种吹填土地基处理施工方法，挖掘机清除表层浮土至水位标高，推土机碾压场地产生液化涌水，挖掘机铲斗土插入土中振冲液化，推土机碾压挤密使超孔隙水排出，用潜水泵抽离场区加速排水固结；晾晒后的干土分层回填压实形成硬壳层，硬壳层阻止地下水上返保持较高的承载力与较低的压缩性；优点为：本发明操作方法简单、承载力显著提高、用时工期短、成本低。
