Umbrella-shaped steel framework expanded-base uplift pile and construction method thereof
The invention relates to an umbrella-shaped steel framework expanded-base uplift pile and a construction method thereof. The umbrella-shaped steel framework expanded-base uplift pile comprises a reinforcement cage, a static pressure bearing screw rod, a pressed platform, an expanded-base steel knife angle and a fixed circular ring, the upper end of the static pressure bearing screw is a pressed platform, the bottom end of the static pressure bearing screw is hinged to an expanded-base steel knife corner, a plurality of fixing rings are welded to the bottom of the reinforcement cage, the static pressure bearing screw is vertically arranged in the reinforcement cage, and the expanded-base steel knife corner penetrates through the fixing rings to be inserted into a soil body. The stability of the underground structure is enhanced, and the safety risk of the underground structure in the construction and operation process is reduced.
本发明涉及一种伞型钢骨架扩底抗拔桩及其施工方法，包括钢筋笼、静压承力螺杆、受压平台、扩底钢刀角和固定圆环；所述静压承力螺杆上端为受压平台，静压承力螺杆底端铰接扩底钢刀角，所述钢筋笼底部一圈焊接若干个固定圆环，静压承力螺杆竖直设于钢筋笼内，扩底钢刀角穿过固定圆环插入土体。本发明增强地下结构的稳定性，降低地下结构在施工和运营过程中的安全风险。
