Temporary anchorage construction method for arch bridge
The invention belongs to the technical field of bridge engineering, and particularly relates to a temporary anchorage construction method for an arch bridge, which is suitable for deep V-shaped valley terrain, meanwhile, most of deep V-shaped valley regions are in bridge-road connection, and bridge-road transition sections are excavation sections. And after the function of temporary anchorage is achieved, the excavation body is removed according to the permanent slope ratio. Mass concrete does not need to be poured to serve as a temporary anchorage, and cost is greatly saved; the construction method is simple and convenient, and the construction period is effectively shortened; construction operation on a steep slope is avoided, and construction safety is guaranteed.
本发明属于桥梁工程技术领域，具体涉及一种拱桥临时锚碇施工方法，适应深V峡谷地形，同时深V峡谷地区大多数为桥路连接，桥路过渡段为挖方地段，本发明通过优化施工顺序，灵活运用桥路过渡段的挖方体作为临时锚碇，待拱圈合拢后，拆除扣锚索，临时锚碇功能实现后，根据永久坡率清除挖方体。本发明无需浇筑大体积混凝土作为临时锚碇，大大节约了成本；该施工方法简单便捷，有效缩短工期；避免了在陡峭边坡施工作业，保证施工安全。
