Concrete arch bridge inclined pile construction technology
The invention discloses a concrete arch bridge inclined pile construction technology, and relates to the technical field of bridge pile foundation excavation construction. Comprising the steps of surveying and lofting, guide wall construction, advance support, inclined pile excavation construction, transverse anchor rod construction, primary concrete spraying, profile steel net frame installation, feet-lock bolt construction, reinforcing mesh installation, connecting steel bar welding, secondary concrete spraying, pile body steel bar binding and concrete pouring. According to the inclined pile support, the hollow transverse anchor rods are matched with the feet-lock anchor rods, the reinforcing mesh is additionally arranged, the support strength is high, the problem that the plateau geology is loose is effectively solved, and meanwhile the full-section excavation construction form of the plateau area is met; through the mode of combining primary spraying and secondary spraying, the problem that concrete pouring is difficult in the deep canyon in the plateau area is effectively solved.
本发明公开了一种混凝土拱桥斜桩施工工艺，涉及桥梁桩基开挖施工技技术领域，包括：测量放样→导向墙施工→超前支护→斜桩开挖施工→横向锚杆施工→混凝土初喷→型钢网架安装→锁脚锚杆施工→钢筋网片安装→连接钢筋焊接→混凝土复喷→桩体钢筋绑扎→混凝土浇筑。本发明斜桩支护采用中空的横向锚杆搭配锁脚锚杆，附加钢筋网片，支护强度高，有效解决高原地质松散问题，同时满足高原地区全断面开挖施工形式；通过初喷和复喷相结合的形式，有效解决高原地区深切峡谷混凝土浇筑困难问题。
