Construction method of suspension type track beam arch bridge structure
The invention discloses a suspension type track beam arch bridge structure construction method and relates to the field of bridge construction. The construction method of the suspension type track beam arch bridge structure comprises the following steps that a whole bridge splicing site is arranged in a splicing area on one side of a designed bridge site, and bridge piers are obtained through construction; an assembling support and a pushing temporary support are built and assembled on the assembling support to obtain a whole bridge structure, and the assembling support is dismantled; a plurality of walking machines are adopted to push the whole bridge structure to the designed bridge position through the pushing temporary support, and the whole bridge structure falls onto the bridge piers; in the pushing process, the position and the elevation of the track beam are adjusted, the positions of two bottom plates of the track beam in the whole bridge structure are limited through a plurality of bottom plate restraining devices, and the distance between openings of the two bottom plates of the track beam within the range of 1-1.5 m in front of and behind the walking machine is kept fixed. According to the construction method of the suspension type track beam arch bridge structure, local steel beam deformation in the pushing process of the track beam is controlled by fixing the distance between the bottom plate longitudinal ribs of the two bottom plates in the track beam in the pushing process.
一种悬挂式轨道梁拱桥结构施工方法，涉及桥梁施工领域。悬挂式轨道梁拱桥结构施工方法包括以下步骤：在设计桥位一侧的拼装区布置整桥拼装场地并施工得到桥墩；搭建拼装支架和顶推临时支架并在拼装支架上拼装得到整桥结构，拆除拼装支架；采用多个步履机将整桥结构使用顶推临时支架顶推至设计桥位处并落梁至桥墩上；在顶推过程中调整轨道梁的位置和标高，并使用多个底板约束装置限定整桥结构中轨道梁的两块底板的位置，使步履机前后1‑1.5m范围内的轨道梁的两块底板之间开口的间距保持固定。本申请提供的悬挂式轨道梁拱桥结构施工方法通过在顶推过程中固定轨道梁中两个底板的底板纵肋间距来控制轨道梁顶推过程中的局部的钢梁变形。
