[0002] The compaction pile can effectively reinforce the foundation above the groundwater level. In recent years, the compaction pile has been widely used. The compaction pile is a pile formed by pressing or driving a steel pipe with a pipe plug, a valve or a cone head into the soil to form a hole and compact the soil layer, and then putting lime soil, sand and gravel into the hole. The main feature of the compaction pile is that it does not require large excavation and filling, and the amount of earthwork is small. Its treatment depth depends on the level of hole-forming machinery and construction technology. Generally, the appropriate treatment depth is 5-15m. The compaction pile composite foundation can effectively eliminate the collapsibility of thick loess in the treatment of collapsible loess foundation. The compaction pile treatment of collapsible loess foundation is to use the lateral compaction effect of hole-forming and layered tamping of lime soil or cement soil to compact the soil between piles and improve the engineering performance, and form a pile body with a certain bearing capacity, which works together with the soil between piles to form a composite foundation; the geogrid in the cushion layer on the top of the pile makes the upper additional stress distribution more reasonable, and the settlement deformation of the foundation is more coordinated.
