Vacuum preloading boundary sealing method
The invention discloses a vacuum preloading boundary sealing method. The method comprises the following steps that (1) the axis of a closed wall is positioned; (2) the depth of a breathable soil layer is determined; (3) slurry for backfilling is mixed, a boundary plastic sealing film is cut, the lower end of the boundary plastic sealing film is connected with a weight, a closed wall groove is excavated, and the bottom of the closed wall groove penetrates through the breathable soil layer and enters an airtight soil layer; (4) a boundary sealing plastic film is vertically lined on the inner side of the closed wall groove; (5) the slurry is backfilled into the closed wall groove to form a slurry wall body, the top surface of the slurry wall body is higher than the bottom surface of the breathable soil layer, and the boundary sealing plastic film and the slurry wall body form the closed wall; and (6) the top of the boundary sealing plastic film is connected with a sealing film of a vacuum preloading area in a sealed mode. When the breathable soil layer at the boundary of a vacuum preloading soft foundation treatment area is thick, the method has the advantages of being easy to operate, convenient to construct, economical, practical, high in reliability, capable of rapidly forming sealing conditions at the boundary of the vacuum preloading area and the like.
本发明公开了一种真空预压边界密封方法，采用以下步骤：①定位闭气墙轴线；②确定透气土层深度；③拌制回填用泥浆、裁剪边界塑料密封膜并在其下端连接坠重物、开挖闭气墙沟槽，闭气墙沟槽的底部穿过透气土层并进入不透气土层；④在闭气墙沟槽的内侧垂衬边界密封塑料膜；⑤在闭气墙沟槽内回填泥浆，构成泥浆墙体，泥浆墙体的顶面高于透气土层的底面，所述边界密封塑料膜和所述泥浆墙体构成闭气墙；⑥将边界密封塑料膜的顶部与真空预压区域密封膜密封连接。当真空预压软基处理区域边界处透气土层较厚时，采用本发明，具有操作简单、施工方便、经济实用、可靠性高、能够快速在真空预压区域边界处形成密封条件等优点。
