Bidirectional spiral soil-squeezing expansion pile for collapsible foundation and construction method
The invention discloses a bidirectional spiral soil-squeezing expansion pile for a collapsible foundation and a construction method, and the bidirectional spiral soil-squeezing expansion pile for the collapsible foundation comprises a secondary compaction soil body layer, an expansion material layer located on the inner side of the compaction soil body layer and a pile body located in the expansion material layer. The invention further relates to a construction method for manufacturing the bidirectional spiral soil-squeezing expansion pile. According to the bidirectional spiral soil-squeezing expansion pile for the collapsible foundation, the stability of the expansion pile is greatly improved through the structure of the compaction soil body layer and the expansion body material layer, particularly, the pile end resistance and the pile side friction resistance are enhanced due to the fact that the pile body is wrapped with the expansion body material, the root fixing and enhancing effects are achieved, and the collapsibility effect of eliminating loess and plain fill is better. The construction method has a good compaction effect, the collapsibility of the foundation can be effectively eliminated, and the bearing capacity of the pile foundation is improved.
本发明公开了一种湿陷性地基用双向螺旋挤土扩体桩及施工方法，其中，一种湿陷性地基用双向螺旋挤土扩体桩，包括二次挤密土体层、位于挤密土体层内侧的扩体材料层以及位于扩体材料层内的桩体。还涉及制作所述双向螺旋挤土扩体桩的施工方法。本发明的湿陷性地基用双向螺旋挤土扩体桩，挤密土体层及扩体材料层的结构大大增加了扩体桩的稳定性，特别是桩体外包裹扩体材料增强了桩端阻力与桩侧摩阻力，具有“根固增强作用”，消除黄土、素填土湿陷性效果更好。本发明施工方法具有较好的挤密作用，能够有效地消除地基的湿陷性，提高桩基的承载能力。
