Vibroflotation reverse circulation replacement foundation treatment method
The invention provides a vibroflotation reverse circulation replacement foundation treatment method. The vibroflotation reverse circulation replacement foundation treatment method comprises the following steps that the position and range of an unqualified soil layer are determined; according to the position and range of the unqualified soil layer, a plurality of suction points and sinking elevations are determined, the construction process of any suction point is characterized in that a steel casing sunk into the top surface of the unqualified soil layer from the suction point, sandy soil in the steel casing is pumped into a sand storage pool by using a suction assembly, the steel casing is continuously sunk to the sinking elevation, the sandy soil in the steel casing is pumped to a wastesand pool by using the suction assembly, a plurality of vibroflotation point positions are distributed, for each vibroflotation point position, a vibroflotation device sinks to the sinking elevation from the vibroflotation point position, and in the vibroflotation process, the suction assembly is used for sucking sandy soil in the steel casing into the waste sand pool till the sucked sandy soil meets the design requirement; and after construction of all the suction points is completed, sand in the sand storage pool is backfilled to the surface of the sandy soil foundation. The method aims to overcome the defects of an existing sandy soil foundation treatment method for dredging and backfilling.
本发明提供了一种振冲反循环置换地基处理方法，包括以下步骤：确定不合格土层的位置和范围；根据不合格土层的位置和范围，确定多个抽吸点和下沉标高，对于任一个抽吸点的施工过程如下：将钢护筒从抽吸点沉入到不合格土层顶面，利用抽吸组件将钢护筒内的砂土抽吸至储砂池；继续将钢护筒沉入到下沉标高，利用抽吸组件将钢护筒内的砂土抽吸至废砂池；布设多个振冲点位，对于每个振冲点位，将振冲器从振冲点位下沉到下沉标高，振冲过程中，利用抽吸组件将钢护筒内的砂土抽吸至废砂池，直至抽吸出的砂土满足设计要求；完成所有抽吸点的施工后，将储砂池内的砂土回填至砂性土地基表面。本发明旨在解决现有疏浚回填的砂性土地基处理方法所存在的不足。
