The invention discloses a pile foundation structure suitable for a soft foundation. The pile foundation structure comprises a pile foundation, a pulling-out device, a plurality of wing plates surrounding the pile foundation and a drainage pipe. The extraction device comprises a high-pressure pump and a material extraction pipe; a butt joint part is arranged on the pile foundation, the pile foundation is a hollow pile, and the bottom is sealed; a second through hole is formed in the butt joint part, the material pumping pipe penetrates through the second through hole to be connected into an inner cavity of the pile foundation, the outer end of the material pumping pipe is connected with the high-pressure pump, a first through hole is formed in the upper end of the pile foundation, the drainage pipeline penetrates through the fourth through holes in the wing plates to be connected into the first through hole, and a plurality of third flange-shaped through holes are formed in the drainage pipeline. The material pumping negative pressure cavity is formed by the cavity of the hollow pile, water in a soft foundation around the pile foundation can be pumped out through the vertical drainage pipeline, and the effect of reinforcing the pile foundation is achieved. Through the connected wing plates, a large pile side contact area can be provided, and soil between the wings can be stressed together, so that the soil between the wings becomes a natural inner support of the pile structure, and the bending resistance and torsion resistance of the pile structure are improved.
本发明公开一种适用于软地基的桩基结构，包括桩基、抽出装置、围绕桩基的若干翼板和排水管；抽出装置包括高压泵和抽料管；桩基上设有对接部，桩基为空心桩，底部密封；对接部上设有通孔二，抽料管穿过通孔二接入桩基内腔中，外端与高压泵连接，桩基的上端设有通孔一，排水管道穿过若干翼板上的通孔四接入通孔一内，在排水管道上设有若干凸缘状通孔三。本申请利用空心桩的空腔形成抽料负压腔，可以利用竖直的排水管道将桩基周围软地基内的水抽出，起到对桩基的加固作用。通过连接的翼板，能提供较大的桩侧接触面积，能携翼间土一起受力，使翼间土成为桩结构的天然内支撑，提高了桩结构的抗弯抗扭性能。
