The invention provides a combined foundation pile structure under water-rich geological or complex geological conditions, and relates to the technical field of foundation piles, the combined foundation pile structure comprises a bearing platform, multiple groups of piles and a reinforcement cage, and the multiple groups of piles penetrate through the edge of the interior of the bearing platform; pile columns and reinforcement cages penetrate through a soft soil layer to reach concrete in pile holes in a strong soil layer, slurry is poured through the pile columns so as to fix the pile holes, in the pouring process, the slurry is firstly poured to fill the concrete in the pile holes, after the concrete in the pile holes is filled, reinforcing pipes are inserted into the pile columns, reinforcement pipes are inserted into the reinforcing pipes, and then the slurry is poured into the reinforcing pipes; as the positioning balls block the limiting protrusions, slurry cannot flow out from the bottom, the steel bar pipe is pushed to drive the reinforcing pipe to move downwards, the steel bar pipe extends out of the bottom of the pile column so that the elastic supporting arms can be opened and fixed in the slurry of concrete in the pile hole, meanwhile, the first side grouting hole and the second side grouting hole are communicated, and the slurry flows out from the side face to reinforce the soft soil layer. The overall stability of the foundation pile is improved.
本发明提供了一种富水地质或者复杂地质条件下的组合基桩结构，涉及基桩技术领域，包括承台、桩柱和钢筋笼，所述桩柱设有多组，且多组所述桩柱贯穿承台内部的边缘处；本发明通过桩柱和钢筋笼贯穿软弱土层至强实土层内的桩孔内砼，通过桩柱浇筑泥浆，以此固定，在浇筑的过程中，先浇筑泥浆填充满桩孔内砼，当充满后，向桩柱内插入加固管，向加固管内插入钢筋管，接着向加固管中浇筑泥浆，由于定位球堵住限位凸起处，泥浆无法从底部流出，推动钢筋管带着加固管向下移动，将钢筋管从桩柱底部伸出使得弹性支臂张开固定在桩孔内砼的泥浆内，同时第一侧灌孔和第二侧灌孔连通，泥浆从侧面流出，对软弱土层处进行加固，提高基桩的整体稳定性。
