[0001] The utility model relates to the technical field of civil engineering, in particular to a collapsible loess roadbed plain soil compaction pile structure. Background Art

[0002] Collapsible loess is a special type of soil that sinks significantly under the influence of water. Compaction pile composite foundations are widely used to improve the performance of this type of foundation. Compaction pile technology uses lateral compaction during hole formation and layered ramming of lime soil or cement soil to compact the soil between the piles, thereby improving the foundation's overall bearing capacity and stability.

[0003] There are also many types of plain soil compaction pile structures for collapsible loess roadbed on the market. For example, Chinese patent CN211690287U discloses a compaction pile for treating collapsible loess foundation in a tunnel, which includes structures such as pile holes. The compaction pile can meet the purpose of eliminating the collapsible nature of the foundation loess in the tunnel. However, the existing plain soil compaction pile structure still has the defect of being easily squeezed and deformed. After the traditional compaction pile structure is driven into the soil, it can squeeze the surface and cause inward concave deformation after long-term use, affecting the firmness of subsequent use. Therefore, a plain soil compaction pile structure for collapsible loess roadbed is proposed to solve the above problem. Utility Model Content
