XU TONG / PENG YAN / ZHANG JINGCHEN / TAN PEIJIE / TANG QINGSONG

The invention discloses an anti-deformation deep foundation pit pile foundation structure and a construction method, the anti-deformation deep foundation pit pile foundation structure comprises a foundation pit support structure, a horizontal anti-deformation pile foundation and a vertical anti-deformation pile foundation, the foundation pit support structure is supported on the side wall of a foundation pit, the horizontal anti-deformation pile foundation is arranged in a soil layer structure on the periphery of the foundation pit, and the vertical anti-deformation pile foundation is arranged on the side wall of the foundation pit. Force borne by the side wall of the foundation pit is balanced; the vertical anti-deformation pile foundation is arranged in a soil layer structure at the bottom of the foundation pit and used for balancing force borne by the bottom of the foundation pit. The horizontal anti-deformation pile foundations are additionally arranged on the periphery of the deep foundation pit structure, and the vertical anti-deformation pile foundations are additionally arranged at the bottom of the deep foundation pit structure, so that the stability of a soil body structure around the deep foundation pit structure is improved, and the situation that the structural stability of the deep foundation pit structure is affected due to deformation is avoided.

本发明公开了一种防变形深基坑桩基结构及施工方法，包括基坑围护结构、水平向防变形桩基和竖直向防变形桩基，所述基坑围护结构支护于基坑的侧壁，所述水平向防变形桩基设置于所述基坑四周的土层结构中，用于平衡基坑侧壁受到的力；所述竖直向防变形桩基设置于所述基坑底部的土层结构中，用于平衡基坑底部受到的力。本发明通过在深基坑结构外围增设水平向防变形桩基和底部增设竖直向防变形桩基，从而来提高深基坑结构周围土体结构的稳定性，进而避免深基坑结构发生变形而影响其结构稳定性。
