Composite pile foundation for loading soil and unloading rock and use method of composite pile foundation
The invention relates to the technical field of composite pile foundations, in particular to a composite pile foundation for loading soil and unloading rock and a using method thereof.The composite pile foundation comprises a spiral anchor and anchor bars, the spiral anchor comprises a hollow rod and an anchor disc, and the top of the hollow rod is fixed to a ground fixing device; the multiple anchor discs are fixed to the outer wall of the hollow rod at intervals. The anchor bar is arranged in the hollow rod, and the outer wall of the anchor bar is in sliding connection with the inner wall of the hollow rod; the top of the hollow rod and the top of the anchor bar are connected with different driving devices correspondingly, different foundations are used according to the geological conditions of upper soil and lower rock and different geologies, the bearing performance of the two foundations is fully utilized, and the strength of the foundations is improved.
本发明涉及复合桩基础的技术领域，具体涉及一种用于上土下岩的复合桩基础及其使用方法，包括螺旋锚和锚筋，所述螺旋锚包括空心杆和锚盘，所述空心杆顶部与地面固定装置相固定；多个所述锚盘间隔固定于所述空心杆外壁；所述锚筋设置于所述空心杆内部，所述锚筋外壁与所述空心杆内壁滑动连接；所述空心杆顶部、锚筋顶部分别与不同的驱动装置相连接，其根据上土下岩的地质条件，根据不同的地质使用不同的基础，充分利用两种基础的承载性能，提高基础的强度。
