Construction method of steel box girder cable-stayed bridge
The invention discloses a construction method of a steel box girder cable-stayed bridge. The construction method comprises the steps that a plurality of buoyancy tanks are arranged on the water surface; a buttress is erected on each floating box; a cable bent tower structure is constructed in the middle of the cable-stayed bridge to be formed; traction equipment is arranged on the cable bent tower structure; pushing platforms are constructed on the two banks of the cable-stayed bridge to be formed respectively; a guide beam and a plurality of steel box girder sections are manufactured on each pushing platform; the guide beams on the two banks and the multiple steel box beam sections are sequentially pushed in the direction of the cable bent tower structure through the traction equipment and the pushing equipment on the two banks till the steel box beam sections on the two banks are closed at the cable bent tower structure, and a main beam is formed; and a plurality of stay cables are tensioned to connect the main beam with the cable bent tower structure, and the cable-stayed bridge is formed. And by arranging the traction equipment and the pushing equipment, it is guaranteed that the steel box girder segments with the large dead weights are subjected to sufficient driving force, continuity in the construction process is guaranteed, and therefore the construction efficiency is improved.
本发明公开了一种钢箱梁斜拉桥的施工方法，包括步骤：在水面设置多个浮箱；在各所述浮箱上搭设支墩；在待成型的所述斜拉桥的中部施作索塔结构；在所述索塔结构上设置牵引设备；分别在待成型的所述斜拉桥的两岸施作顶推平台；在各所述顶推平台上制作导梁和多个钢箱梁节段；利用所述牵引设备和两岸的所述顶推设备分别将两岸的所述导梁和多个所述钢箱梁节段朝所述索塔结构的方向依次顶推，直至两岸的所述钢箱梁节段在所述索塔结构处合龙，形成主梁；张拉多根斜拉索将所述主梁与所述索塔结构连接，成型出所述斜拉桥。通过设置牵引设备和顶推设备保证自重较大的钢箱梁节段受到足够的驱动力，保证施工过程中的连续性，从而提高施工效率。
