Dredger fill foundation treatment method
The invention relates to a dredger fill foundation treatment method, which comprises the following steps of: firstly performing vacuum forced drainage, then performing dynamic compaction, continuing vacuum forced drainage after dynamic compaction, circulating for 2-3 times, performing low-energy full compaction, and detecting the foundation treatment effect. The construction method comprises the following detailed steps: determining process parameters, leveling a site, and inserting a foundation short pipe and a long pipe, carrying out first precipitation, reducing an underground water level to a designed elevation, removing the short pipe and carrying out first dynamic compaction, backfilling and leveling the site, carrying out second precipitation, removing the long pipe and carrying out second dynamic compaction, backfilling and leveling the site, and re-inserting all the long pipes in an original site. And the previous step is repeated, small-energy full compaction is carried out, the site is leveled and rolled, foundation test detection is carried out, detection is qualified, and roadbed filling is carried out. By reducing the underground water level, the problem of excess pore water pressure dissipation when a soft soil foundation is treated by a dynamic compaction method is solved; and through the dynamic effect of the dynamic compaction method, the problems of low soil consolidation speed and large post-construction settlement of a traditional consolidation method are solved.
本发明是一种吹填土地基处理方法，其步骤为：先进行真空强排水，然后进行强夯，强夯后继续真空强排水，如此循环2～3遍后，进行低能满夯，检测地基处理效果。其详细步骤如下：确定工艺参数→场地平整，插入地基短管和长管→第1次降水→地下水位降至设计标高→撤掉短管，第1次强夯→场地回填平整→第2次降水→撤掉长管，第2次强夯→场地回填平整→原点位全部复插长管，反复上一步骤→小能量满夯，场地平整碾压→地基试验检测→检测合格→路基填筑。本发明通过降低地下水位，解决了强夯法处理软土地基时的超孔隙水压力消散问题；通过强夯法的动力效应，解决了传统固结法土体固结速度慢、工后沉降大的问题。
