Self-anchored suspension bridge steel box girder framing pushing equipment and pushing method thereof
The invention discloses a self-anchored suspension bridge steel box girder framing pushing device which comprises a first arc-shaped supporting structure, a second arc-shaped supporting structure and a supporting base installed at the bottom end of the first arc-shaped supporting structure and the bottom end of the second arc-shaped supporting structure, and the first arc-shaped supporting structure comprises at least two first arc-shaped cushion blocks fixed to the upper portion of the supporting base. The second arc-shaped supporting structure comprises a second arc-shaped cushion block located between the two first arc-shaped cushion blocks, a jacking mechanism connected between the second arc-shaped cushion block and the supporting base and a translation mechanism used for driving the second arc-shaped cushion block to move between the two first arc-shaped cushion blocks. The top end faces of the first arc-shaped cushion block and the second arc-shaped cushion block are each provided with a groove used for being matched with a protruding block at the bottom of the steel box girder. According to the self-anchored suspension bridge steel box girder framing pushing equipment, the defect that existing pushing equipment cannot adapt to arc section girder bottom pushing operation is overcome, welding, dismantling and repairing work and materials of a large number of temporary structures are saved, the construction efficiency is improved, and meanwhile energy saving and environmental protection are achieved.
本发明公开了一种自锚式悬索桥钢箱梁分幅顶推设备，包括第一弧形支撑结构、第二弧形支撑结构以及安装于第一弧形支撑结构和第二弧形支撑结构底端的支撑底座，第一弧形支撑结构包括固定于支撑底座上方的至少两第一弧形垫块，第二弧形支撑结构包括位于两第一弧形垫块中间的第二弧形垫块、连接第二弧形垫块和支撑底座之间的顶升机构以及用于驱动第二弧形垫块在两第一弧形垫块之间移动的平移机构，第一弧形垫块和第二弧形垫块顶端面上均开设有用于与钢箱梁底部凸块适配的凹槽。本发明提出的自锚式悬索桥钢箱梁分幅顶推设备，解决了现有顶推设备无法适应圆弧段梁底顶推作业的弊端，节省了大量临时结构的焊接、拆除、修复工作和材料，提高施工效率的同时节能又环保。
