Construction method of prefabricated steel box girder pedestrian landscape bridge
The invention relates to a construction method of a prefabricated steel box girder pedestrian landscape bridge. The construction method comprises the following steps that S1, cofferdams are built in riverways on the two sides in the width direction of the riverways, and a plurality of pouring piles are poured; S2, a plurality of arch rib sections and box girder sections are prefabricated; S3, thearch rib sections are sequentially hoisted and installed on the pouring piles to form complete arch ribs, and then the box girder sections are installed on the pouring piles to form a steel box girder; S4, a plurality of auxiliary cables are tensioned between the steel box girder and the arch ribs; and S5, a bridge deck is laid on the top surface of the steel box girder. The construction method has the effects of improving the overall construction efficiency of a bridge and reducing the influence of construction on river navigation.
本申请涉及一种预制钢箱梁人行景观桥的施工方法，包括以下步骤：S1、在河道宽度方向两侧河道内进行围堰并浇筑若干浇筑桩；S2、预制作若干个拱肋段和箱梁段；S3、在浇筑桩上依次吊设安装拱肋段形成完整拱肋，然后在浇筑桩上安装箱梁段形成钢箱梁；S4、在钢箱梁和拱肋之间张设若干附力索：S5、在钢箱梁顶面上铺装桥面。本申请具有提高桥梁整体施工效率，降低施工对河道通航影响的效果。
