Foundation treatment method for preloading drainage consolidation
The invention relates to a preloading drainage consolidation foundation treatment method which comprises the following steps: constructing a vertical drainage well and a temporary retaining wall unit at the boundary position of a to-be-treated foundation, and fixing the temporary retaining wall unit on the to-be-treated foundation through a soil anchor rod; a sand cushion layer is constructed in the temporary retaining wall unit, a horizontal drainage structure is embedded in the temporary retaining wall unit, the sand cushion layer is communicated with the vertical drainage well and the horizontal drainage structure, and soil is filled and compacted above the sand cushion layer; a vertical drainage well and a temporary retaining wall unit are constructed around the boundary position of a foundation to be treated to form an enclosure, a stacking body is filled in the enclosure range, the vertical drainage well, a sand cushion layer and a horizontal drainage structure are constructed in the area when the stacking body is filled, and the horizontal drainage structure is communicated with a horizontal drainage structure in the temporary retaining wall unit. The method has the advantages that the load difference between the pre-pressing stacking area and the temporary retaining wall is small, differential settlement is reduced, and stable operation of a drainage system is effectively guaranteed; drained water in the foundation treatment process can be conveniently and uniformly collected and guided.
本发明涉及一种堆载预压排水固结的地基处理方法，在待处理地基的边界位置施作竖向排水井和临时挡墙单元，临时挡墙单元通过土层锚杆固定在待处理地基之上；在临时挡墙单元内施作砂垫层并埋设水平排水结构，该砂垫层与竖向排水井与水平排水结构连通，在砂垫层的上方填土压实；围绕待处理地基的边界位置施工竖向排水井和临时挡墙单元形成包围，在包围范围内填筑堆载体，在堆载体的填筑时在区域内施作竖向排水井、砂垫层以及水平排水结构，该水平排水结构与临时挡墙单元内的水平排水结构相连通。本发明的优点是：预压堆载区和临时挡墙的荷载差异较小，减少不均匀沉降，有效保障了排水系统的稳定运行；便于统一收集引导地基处理过程中的排水。
