Collapsible loess is unsaturated, under-pressure dense soil, which has low compressibility and high strength under natural humidity, but is soaked in water to cause large collapsible deformation under the influence of additional pressure or self-weight pressure. Therefore, the soil must be treated to be used as the foundation of the building. Because the soil body is hard, the pore-forming is extremely difficult, the water content is lower, the maximum dry density is not easy to reach, and the compaction effect on the soil body is not obvious. At present, a pre-soaking method is adopted, water from the surface layer to the deep layer is often soaked unevenly, and the pore-forming compaction effect is poor.

However, the traditional pre-soaking method has large water consumption and long construction period, and generally, the time required for stabilizing the site from pre-soaking to sinking and for the water content of the soil to reach a certain requirement is at least about one year, so that the construction period is prolonged to a great extent, and the construction cost is improved. Can not meet the requirement of short period of return on investment of current massive project construction.

Therefore, a device for synchronously injecting water and humidifying for a static pressure immersed tube compaction pile, which can reduce the working procedures, the construction period and the construction cost, is needed.
