Rotary excavating end bearing pile foundation in backfill soil and construction method
The invention relates to a rotary excavating end bearing pile foundation in backfill soil, which comprises a reinforcement cage, a plurality of support frames connected to the outer part of the reinforcement cage, and isolation pieces connected to the support frames and wrapping the reinforcement cage in the length direction of the reinforcement cage, the supporting frame comprises two first arc-shaped rods, four connecting rods, four connecting columns and two second arc-shaped rods. The two ends of the four connecting rods and the two ends of the four connecting columns are fixedly connected to the ends of the two first arc-shaped rods and the ends of the two second arc-shaped rods respectively. The supporting frame further comprises a nut and a screw, the nut is fixedly connected to the side close to the second arc-shaped rod, the screw is used in cooperation with the nut, and the isolation piece is connected to the supporting frame through the screw. The method has the effects that the friction resistance between the forming end bearing pile body and the surrounding slope body is reduced, and the stability of the pile body is improved.
本申请涉及一种回填土中旋挖端承桩基，包括钢筋笼，桩基还包括连接在所述钢筋笼外部的多个支撑架，以及连接在所述支撑架上且绕钢筋笼长度方向包裹钢筋笼的隔离件；所述支撑架包括两根第一弧形杆、四根连杆、四根连接柱，以及两根第二弧形杆，四根所述连杆的两端以及四根所述连接柱的两端分别固接在两根所述第一弧形杆和两根所述第二弧形杆的端部上；支撑架还包括固接在靠近第二弧形杆一侧上的螺母，以及与所述螺母配合使用的螺钉，所述隔离件通过所述螺钉连接在支撑架上。本申请具有减小成型端承桩身与其周围坡体之间的摩擦阻力，并提升桩身稳定性的效果。
