Arch-first and beam-second construction method for bracket-free tied arch
The invention discloses an arch-first and beam-second construction method for a bracket-free tied arch, and belongs to the technical field of building construction. The method comprises the followingsteps: 1, transporting arch ribs; 2, pre-burying arch ribs of arch foot sections; 3, temporarily solidifying the arch feet and the bridge piers; 4, penetrating a temporary cable for construction: pulling the temporary cable to the cross beam at the mounting end, fixing the temporary cable through an anchorage device, and circularly constructing and penetrating the cable until the end; 5, hoistingarch ribs; 6, mounting a wind brace; 7, performing pressure injection on arch rib concrete; 8, performing suspender prestressed cable construction; 9, mounting a tie beam and a middle cross beam; 10,installing prefabricated bridge decks, bridge deck pavement and anti-collision guardrails; and 11, adjusting the cable force of the finished bridge suspender. By the adoption of the construction method, the construction period is shortened, and the labor intensity of workers is reduced; and the navigation requirement is guaranteed during construction, the balance of stress changes in arch structure construction is effectively guaranteed, the safety of bridge construction and later operation is guaranteed, the ecological environment is protected, and wide application and popularization value and reference significance are achieved.
一种无支架系杆拱先拱后梁施工方法，属于建筑施工技术领域。它包括以下步骤：1、拱肋运输；2、拱脚段拱肋预埋；3、拱脚与桥墩临时固结；4、穿施工用临时索：临时索拉至安装端横梁处，通过锚具固定，循环施工穿索至结束；5、拱肋吊装；6、安装风撑；7、拱肋混凝土压注；8、吊杆预应力索施工；9、系梁和中横梁安装；10、安装预制桥面板、桥面铺装和防撞护栏；11、成桥吊杆索力的调整。本发明采用一种无支架先拱后梁的施工方法，缩短了施工工期、降低工人劳动强度；且施工时保证通航要求，有效保障了拱形结构施工当中受力变化的均衡性，确保了桥梁施工和后期的运营安全，保护了生态环境，具有广泛的推广应用价值和借鉴意义。
