Pile foundation structure and construction method thereof

LI BIN / XIA YINAN / LIU CHAOZE

The invention discloses a pile foundation structure and a construction method thereof, and relates to the technical field of pile foundations, the pile foundation structure comprises a pile hole, a pile body arranged in a soil layer and used for containing a pile foundation and arranged in the pile hole, the pile body sequentially comprises multiple sections of pile foundation units in the length direction of the pile body, and a limiting mechanism is arranged between every two adjacent pile foundation units; the pile holes are used for limiting the displacement between the adjacent pile foundation units, working spaces are formed between the pile holes and the pile foundation, the working spaces are filled with filler, the length of each pile foundation unit is smaller than 0.5 m, and the self weight of each pile foundation unit is smaller than 200 kg. The problem that in the prior art, it is difficult to install the precast pile in the absence of large mechanical equipment is solved.

本发明公开了一种桩基结构及其施工方法，涉及桩基技术领域，包括桩孔，设置在土层中，用于容纳桩基桩体，设置在桩孔中，所述桩体沿自身长度方向依次包括多段桩基单元，相邻桩基单元之间设置有限位机构，用于限制相邻桩基单元之间的位移，其中，所述桩孔与桩基之间具有工作空间，所述工作空间内填充有填料，其中，桩基单元的长度小于0.5m，自重小于200kg。通过本发明解决了现有技术中难以在缺少大型机械设备情况下安装预制桩的问题。
