Iron tower pile foundation structure and preparation method thereof
The invention discloses an iron tower pile foundation structure and a preparation method thereof. The iron tower pile foundation structure comprises a foundation pit, a bearing platform, reinforcing ribs, anchor bar holes and anchor bars. The foundation pit is formed by vertically excavating downwards in a soil body, the bearing platform comprises an upper bearing platform and a lower bearing platform, the lower bearing platform is matched with the foundation pit and located in the foundation pit, the upper bearing platform is located above the lower bearing platform, and the central axis of the upper bearing platform is the same as that of the lower bearing platform. The reinforcing ribs are fixedly connected inside the bearing platform. The anchor bar holes are vertically and downwards formed in the bottom of the lower bearing platform at preset intervals, the depth of each anchor bar hole is 1900-2000 mm, the diameter of each anchor bar is smaller than the hole diameter of each anchor bar hole, the anchor bars are vertically and downwards inserted into the anchor bar holes from the centers of the anchor bar holes, fine sand concrete is poured into the anchor bar holes to fix theanchor bars in the anchor bar holes, and the top ends of the anchor bars are located in the lower bearing platform. The anchor bars are used for dispersing and transmitting the gravity of the iron tower borne by the bearing platform into a rock stratum, the bearing platform burden is reduced, the strength and stability of an iron tower pile foundation structure are enhanced, iron tower stable arrangement in plateau areas and geologic weak areas is achieved, and safety and reliability are improved.
本发明公开一种铁塔桩基结构及其制备方法，包括：基坑、承台、加强筋、锚筋孔和锚筋；基坑在土体中竖直向下挖掘而成，承台包括上承台与下承台，所述下承台与基坑匹配且位于基坑内，上承台位于下承台上方且上承台与下承台中轴线相同；加强筋固定连接在承台内部；所述锚筋孔为下承台底部均匀间隔预定距离竖直向下开设的孔洞，其深度为1900‑2000mm，锚筋直径小于锚筋孔孔径，从锚筋孔中央竖直向下插入锚筋孔，通过向锚筋孔浇筑细砂混凝土将锚筋固定在锚筋孔内，锚筋顶端位于下承台内。本发明利用锚筋将承台承受铁塔的重力分散传至岩层中，降低承台负担，增强铁塔桩基结构的强度和稳定性，满足高原地区和地质软弱区域的铁塔稳固设置、提高安全性和可靠性。
