Arc-shaped overhanging landscape bridge closure section position construction method
The invention relates to the technical field of installation of closure section steel box girders of landscape bridges, and provides an arc-shaped overhanging landscape bridge closure section position construction method for solving the problem that closure section steel box girder position setting construction is difficult, and before closure section steel box girders are installed, the end of a corresponding tail standard section steel box girder is jacked up through a lifting assembly to form a flaring, and then the end of the corresponding tail standard section steel box girder is jacked up to form an arc-shaped overhanging landscape bridge closure section position setting construction is completed. Then the three-way jack drives the closure section steel box girder to move downwards and be clamped between the two sets of tail section standard section steel box girders, and finally the lifting assembly and the three-way jack drive the tail section standard section steel box girders and the closure section steel box girder to move downwards together, so that accurate positioning installation of the closure section steel box girder is achieved. The method has the effect of facilitating accurate positioning installation of the closure section steel box girder.
本申请涉及景观桥合拢段钢箱梁安装的技术领域，针对合拢段钢箱梁落位施工困难的问题，提出了一种弧形悬挑景观桥合拢段落位施工方法，通过在安装合拢段钢箱梁前，利用升降组件将对应末节标准段钢箱梁的端部顶起形成扩口，再通过三向千斤顶驱使合拢段钢箱梁下移并卡入两组末节标准段钢箱梁之间，最后再通过升降组件与三向千斤顶分别驱使末节标准段钢箱梁以及合拢段钢箱梁一同下移，实现合拢段钢箱梁的精准落位安装，本申请具有便于合拢段钢箱梁精准落位安装的效果。
