Stay cable spiral anchor-pile system and construction method
The invention discloses a stay cable spiral anchor-pile system and a construction method, and belongs to the field of pile foundation engineering, the stay cable spiral anchor-pile system comprises a main pile foundation, an anchor cable, a spiral anchor and a ratchet drill rod assembly, the bottom end of the main pile foundation extends below a freezing depth line of soil, the top end of the main pile foundation is exposed out of a ground line, and a plurality of lifting lugs are uniformly arranged around the side wall of the top end of the main pile foundation; the spiral anchors are obliquely arranged on one side of the main pile foundation, the number of the spiral anchors is the same as that of the lifting lugs, the positions of the spiral anchors correspond to the positions of the lifting lugs one to one, the top end of the ratchet drill rod assembly is connected with a drilling machine, and the bottom end of the ratchet drill rod assembly is in driving connection with the top ends of the spiral anchors. One end of the anchor cable is fixed to the top end of the spiral anchor, and the other end of the anchor cable is fixed to the lifting lug. The multiple spiral anchors are obliquely anchored below the freezing depth line around the main pile foundation, the top end of the main pile foundation is obliquely pulled through the anchor cables extending out of the spiral anchors, and freezing pulling displacement of the main pile foundation is avoided.
本发明公开一种斜拉索螺旋锚‑桩系统及施工方法，属于桩基础工程领域，包括：主桩基础、锚索、螺旋锚和棘轮钻杆组件，所述主桩基础的底端伸入到土壤的冻深线以下，顶端漏出地面线，所述主桩基础的顶端侧壁周围均匀设置有多个吊耳，所述螺旋锚在所述主桩基础一侧倾斜布置，所述螺旋锚的数量设置为多个，且与所述吊耳数量相同，多个所述螺旋锚的位置与多个所述吊耳一一对应，所述棘轮钻杆组件顶端与钻机连接，底端与所述螺旋锚的顶端驱动连接，所述锚索一端固定在所述螺旋锚的顶端，另一端固定在所述吊耳上。本发明将多个螺旋锚倾斜锚固在主桩基础周围的冻深线以下，通过螺旋锚上伸出的锚索斜拉主桩基础的顶端，避免了主桩基础的冻拔位移。
