Construction method for reinforcing deep and thick silt stratum open caisson foundation pit
The invention discloses a construction method for reinforcing a deep and thick silt stratum open caisson foundation pit. The construction method comprises the following steps that S100, a plurality of water stop piles are installed in the circumferential direction of the foundation pit; S200, a plurality of first bottom sealing piles and a plurality of second bottom sealing piles are installed at the bottom of the foundation pit, and the first bottom sealing piles are located on the peripheries of the second bottom sealing piles; and S300, open caisson side walls are installed on the first bottom sealing piles. By applying the construction method for reinforcing the deep and thick silt stratum open caisson foundation pit, the phenomena of mud gushing and sand flowing in the sinking process of an open caisson can be reduced.
本发明公开了一种深厚淤泥地层沉井基坑加固的施工方法，包括如下步骤：S100，沿基坑的周向，安装多个止水桩；S200，在基坑底部，安装多个第一封底桩和多个第二封底桩，第一封底桩位于第二封底桩的外围；S300，在第一封底桩上安装沉井侧壁，应用上述深厚淤泥地层沉井基坑加固的施工方法，能够减少沉井下沉过程当中的涌泥及流砂现象。
