[0002] Ground treatment is an engineering measure to improve the bearing capacity, deformation performance or impermeability of the foundation (soil or rock) supporting the building. Ground treatment includes a variety of methods, such as compaction, tamping, replacement, preloading and composite foundation, as well as grouting and micropiles, etc., with the aim of improving the stability and bearing capacity of the foundation, reducing deformation and uneven settlement, improving the compressibility, permeability and dynamic characteristics of the soil, and solving special problems of special soils.

[0003] Among them, compaction piles are also a common method for foundation treatment. It mainly forms pile holes in the soil, fills the holes with specific materials (such as plain soil, gray soil, sand and gravel, etc.), and then compacts them layer by layer to improve the density and bearing capacity of the soil. Compaction piles are suitable for a variety of soil conditions, especially in the treatment of soft soil foundations and collapsible loess foundations. Compared with the traditional excavation and soil replacement method, compaction pile technology does not require a large amount of excavation and backfilling, so it can save a lot of manpower and material resources, while shortening the construction period.

[0004] The existing compaction pile holes are generally formed by impact of a hammer. Since the inner walls of some compaction pile holes are not provided with supporting and protective structures, the soil around the pile holes is easily affected by the vibrations generated by the hammer and falls into the center of the pile hole, resulting in certain impurities in the compaction pile after forming, thereby reducing the overall strength of the compaction pile.
