A double-steel-pipe support pile structure comprises a pile body, the pile body comprises an outer pipe, an inner pipe is connected in the outer pipe in a sleeved mode, the outer pipe and the inner pipe are fixedly connected in the axial direction through a plurality of longitudinal ribs and fixedly connected in the radial direction at intervals through at least two annular transverse ribs, every two adjacent transverse ribs form a partition cavity communicated in the circumferential direction, and the outer pipe and the inner pipe are fixedly connected in a sleeved mode. Each layer of partition cavity is fixedly connected with a connecting pipe, one end of each connecting pipe is communicated with the corresponding partition cavity, the other end of each connecting pipe is arranged between the outer pipe and the inner pipe in the axial direction and penetrates through the topmost transverse rib, a plurality of through holes A are distributed in the pipe wall of the outer pipe, one-way valves A are installed in the through holes A, a plurality of through holes B are distributed in the pipe wall of the inner pipe, and one-way valves A are installed in the through holes B. A one-way valve B is installed in the through hole B. The flow direction of the one-way valve A and the flow direction of the one-way valve B face the outside from the partition cavity. Through the use of the double-layer steel pipe support pile, the'soil plug effect 'during use is overcome through water injection and pressure bearing, and the repeated use of the steel pipe support pile is realized.
一种双钢管支护桩结构，包括,桩体，所述桩体包括外管，所述外管内套接有内管，所述外管与内管之间沿轴向通过多条纵肋固定连接、沿径向通过至少二条环形的横肋间隔固定连接，相邻两个所述横肋形成沿圆周方向联通的隔腔，每层隔腔分别固定连接一根连接管，所述连接管一端联通隔腔，另一端沿轴向设于所述外管与内管之间并穿过最顶部的横肋，所述外管管壁上分布有多个通孔A，所述通孔A内安装有单向阀A，所述内管管壁上分布有多个通孔B，所述通孔B内安装有单向阀B，所述单向阀A与单向阀B流向均由隔腔朝向外部设置。本发明通过双层钢管支护桩的使用，通过注水承压来克服使用时的“土塞效应”，实现钢管支护桩的重复使用。
