Arch self-adaptive anchoring construction method for replacing sling of box-type arch bridge
The invention discloses an on-arch self-adaptive anchoring construction method for sling replacement of a box-type arch bridge, belongs to the technical field of sling replacement, and solves the technical problems that an existing leveling anchoring structure system is complex and cannot be recycled. The construction method comprises the following steps: step 1, installing a temporary suspender system; step 2, converting the cable force of a to-be-replaced sling to a temporary sling step by step, and dismantling the to-be-replaced sling; 3, after the new sling is installed, the sling force of the temporary sling is converted to the new sling step by step, and anchoring is conducted after the new sling is tensioned in place; and 4, the temporary suspender system is dismantled, and the next sling to be replaced is replaced. In the sling replacement and sling force conversion process, an original structure stress system is not changed, the influence on original structure stress is small, the temporary suspender system can be assembled, disassembled and recycled, the structure is light, the manual operation intensity is small, the work efficiency is high, the cost is low, and the temporary suspender system can be recycled to similar projects of the same type.
本发明公开了一种用于箱型拱桥吊索更换的拱上自适应锚固施工方法，属于吊索更换技术领域，解决现有调平锚固结构体系复杂，不能周转使用的技术问题。施工方法包括以下步骤：步骤1.安装临时吊杆体系，步骤2.逐级将待更换吊索的索力转换至临时吊索，拆除待更换吊索；步骤3.安装新吊索完毕，逐级将临时吊索的索力转换至新吊索，新吊索张拉到位后进行锚固；步骤4.拆除临时吊杆体系，更换下一根待更换吊索。本发明在吊索更换索力转换过程中，未改变原结构受力体系，对原结构受力影响较小，临时吊杆体系可装配式安拆周转使用，且结构轻量化，人工作业强度小，工效高，成本经济，可周转至类似同类型项目使用。
