Incremental launching construction method for basket type steel arch bridge with arch rib assembling support serving as temporary supporting rod
The invention discloses an incremental launching construction method for a basket type steel arch bridge with an arch rib assembly support serving as a temporary supporting rod. The incremental launching construction method for the basket type steel arch bridge with the arch rib assembly support serving as the temporary supporting rod comprises the steps that the arch rib assembly support is designed to be a support with a splayed transverse bridge direction; a transverse connecting system is arranged in the middle according to the requirement of the stability of the bracket; the support stand columns on the two sides are main stress rod pieces of the support in the assembling stage and the pushing stage. Column feet are arranged on the lower portions of the support stand columns, column heads are arranged on the upper portions of the support stand columns, and the column heads and the column feet are connected with arch ribs and straining beams in a bolted or welded mode. The construction process comprises the following steps: (1) mounting the arch rib assembly bracket, (2) assembling the arch ribs on the bracket until closure, and (3) carrying out incremental launching construction. The method mainly has the following advantages that each support stand column bears part of the weight of the arch rib sections and transmits the weight to the tie beam, the tie beam is stressed evenly in the pushing stage, the number of temporary projects is greatly reduced, and the construction time is greatly shortened.
本发明公开了一种拱肋拼装支架兼作临时撑杆的提篮式钢拱桥顶推施工方法，拱肋拼装支架兼作临时撑杆的提篮式钢拱桥顶推施工方法：将拱肋拼装支架设计成横桥向为八字形的支架；两侧为立柱，中间根据支架稳定性的需要设置横向连接系；两侧支架立柱为拼装阶段和顶推阶段支架的主要受力杆件；支架立柱下部设置柱脚，上部设置柱头，柱头与柱脚采用螺栓连接或焊接的方式与拱肋和系梁连接；施工流程为：①安装拱肋拼装支架，②在支架上拼装拱肋至合龙，③顶推施工。主要有以下优点：①使每个支架立柱分别承担一部分拱肋节段的重量，并传递到系梁上，使得顶推阶段系梁受力较为均匀，②大幅减少临时工程数量，③大幅减少施工时间。
