Pile-anchor supporting structure for pre-stressed anchor cable tensioning of concrete pedestal and construction method
The invention discloses a pile-anchor supporting structure for pre-stressed anchor cable tensioning of a concrete pedestal and a construction method of the pile-anchor supporting structure. The pile-anchor supporting structure comprises a fender post, the upper portion of the fender post is connected with a top beam, a main rib of the fender post is welded with a pre-embedded anchor cable sleeve, and a lateral reinforcing mesh and a transverse tie bar are erected in the lateral direction of the fender post; a pre-stressed anchor cable is placed in the pre-embedded anchor cable sleeve and then is grouted, the pre-stressed anchor cable penetrates through the fender post, and the tail end of the pre-stressed anchor cable is fixedly connected with a guide cap; reinforcing meshes are embedded in the positions, close to the front ends of the pre-stressed anchor cables, of the fender posts, and concrete is poured to form a pedestal; and after the pre-stressed anchor cables are locked, anchor sealing reinforcing steel bars are embedded into the pedestal concrete, and anchor sealing concrete is poured into the pedestal concrete. The anchor cable penetrates through the pile body through the pre-embedded steel pipe, the pre-stressed anchor cable is tensioned through the concrete pedestal, stress is direct, the structural integrity is high, the excavation width of the foundation pit is small, and safety is high.
本发明公开了一种混凝土台座进行预应力锚索张拉的桩锚支护结构及其施工方法，包括围护桩，所述围护桩上方连接冠梁，所述围护桩的主筋焊接预埋锚索套管，所述围护桩侧向架设有侧向钢筋网和横向拉筋；所述预埋锚索套管内放置预应力锚索后注浆，所述预应力锚索贯穿所述围护桩，所述预应力锚索的末端固定连接导向帽；所述围护桩靠近所述预应力锚索前端位置处植入钢筋网片并浇筑混凝土形成台座；还包括配套定型锚具，其锁定所述预应力锚索后，在所述台座混凝土中植入封锚钢筋并浇筑封锚混凝土。本发明将锚索通过预埋钢管贯穿桩身，通过混凝土台座张拉预应力锚索，受力直接，结构整体性强，基坑开挖宽度小、安全性高。
