Double-layer steel truss bridge construction technology
The invention relates to the technical field of building construction, in particular to a double-layer steel truss bridge construction technology which comprises the following steps: S1, construction preparation; s2, surveying and setting out; s3, foundation construction-temporary support erection; s4, crane airport installation and detection-segmented steel box girder transportation; s5, steel box girder erection, pier cross beam installation, adjustment and midspan segmented girder installation; s6, adjusting linearity and elevation; s7, steel beam welding, butt joint adjusting, main welding seam welding and other welding seam welding; s8, connecting truss welding; s9, carrying out nondestructive testing; s10, steel bridge falling-coating ending is carried out; and S11, dismantling the temporary support. The purpose of the invention is to effectively solve the problem of poor supporting stability of an upper-layer bridge body in a double-layer bridge structure.
本申请涉及建筑施工技术领域，尤其是涉及一种双层钢桁架桥梁施工工艺，其包括以下步骤：S1、施工准备；S2、测量放线；S3、基础施工‑临时支架搭设；S4、吊机机场安装及检测‑分段钢箱梁运输；S5、钢箱梁架设‑墩横梁安装‑调整‑跨中分段梁安装；S6、线性及标高调整；S7、钢梁焊接‑调整对接缝‑主焊缝焊接‑其他焊缝焊接；S8、连接桁架焊接；S9、无损检测；S10、钢桥落架‑涂装收尾；S11、临时支架拆除。本申请的目的是为了有效解决双层桥梁结构中上层桥体支撑稳定性差的问题。
