Construction method of bent arch suspension bridge
The invention discloses a construction method of a bent arch suspension bridge, and relates to the technical field of bridge engineering, and the construction method comprises the following steps: building a pair of skewbacks which are symmetrically arranged on the two sides of the width direction of an existing road; a rotating hinge is mounted at the top end of each skewback; two half auxiliary arches are assembled on the assembling support, and the bottom end of each half auxiliary arch is hinged to a rotating hinge: the two half auxiliary arches rotate around the rotating hinge and are folded to form a main auxiliary arch; multiple groups of main and auxiliary arches are repeatedly constructed at equal intervals in the length direction of the existing road to form a main and auxiliary arch framed bent; starting from the first section of the steel beam section by using a deck crane, mounting the rest of the steel beam sections section by section while walking; every time one steel beam section is hoisted, the steel beam sections are hung on the corresponding main and auxiliary arches through the slings until the steel beam sections are folded. According to the construction method of the bent arch suspension bridge, the technical problems that the bent arch suspension bridge spans with a small included angle with an existing road and meets the requirement of high traffic protection are solved.
本申请公开了一种排架拱形悬吊桥的施工方法，涉及桥梁工程技术领域，其包括：建造一对拱座，一对拱座对称设置于既有道路宽度方向两侧；每个拱座顶端安装转动铰；在拼装支架上，组装两个半副拱，每个半副拱的底端铰接于转动铰：将两个半副拱绕转动铰转动，合拢成主副拱；沿既有道路长度方向等间距重复建造多组主副拱，形成主副拱排架；用桥面吊机从首段钢梁节段开始，边行走边逐节段安装剩余的钢梁节段；每吊运一段钢梁节段，用吊索将钢梁节段吊挂于对应的主副拱，直至钢梁节段完成合拢。本申请的排架拱形悬吊桥的施工方法，解决了排架拱形悬吊桥与既有道路呈较小夹角跨越且满足高保通要求的技术问题。
