Description
Compaction pile is a new type of lime soil compaction pile, which is one of the methods of soft soil foundation consolidation treatment. Generally, it is widely used in collapsible loess areas. The rotary method is used to drill drill pipe into the foundation and form pile holes after lifting drill, and then backfill and tamp plain soil, lime soil and other materials to form pile body with increased diameter, and form composite foundation together with the original foundation.
The feature is that it is not unearthed, and the original foundation is compressed into holes; When backfilling the material, tamp the material to further expand the hole. Lateral compaction is used for pile formation, which can also achieve the maximum dry density index after the required compaction treatment, and can eliminate the collapsibility of the foundation soil, improve the bearing capacity and reduce the compressibility.
Advantages
1, can replace static pressure pile machine and diesel hammer pile machine, high efficiency, energy saving;
2, good environmental protection effect, no noise, no vibration, no emissions, no excavation.
