Construction method of large-span navigation hole lifting trestle
The invention provides a construction method of a large-span navigation hole lifting trestle. The construction method comprises the steps that steel pipe piles of a lifting frame are arranged at the ends of original trestles on the two banks of a river channel; a dragging sliding rail is arranged on the bridge surface of the original trestle; the guide beams are spliced section by section, and the guide beams are pushed towards the opposite bank direction along the dragging and sliding rails, so that part of the guide beams are suspended above the river channel; a bridge body frame of the navigation hole lifting trestle bridge is spliced to the rear ends of the guide beams in a segmented mode, and the bridge body frame is gradually propelled towards the opposite shore direction; the guide beams reaching the opposite bank are gradually dismantled; the two ends of the bridge body frame are located at the ends of the original trestle on the two banks of the river channel correspondingly; mounting a lifting frame; a bridge deck structure is laid on the bridge body frame. The method is used for overcoming the defect that in the prior art, it is difficult to erect a lifting trestle above a large-span navigable river channel, and a simple, convenient and efficient lifting trestle construction scheme is achieved.
本发明提供一种大跨径通航孔提升栈桥的施工方法，包括：在河道两岸的原栈桥的端部位置设置提升架的钢管桩；在原栈桥的桥面上设置拖拉滑移轨道；分节段拼装导梁，并将导梁沿拖拉滑移轨道向对岸方向推进，使部分导梁悬于河道的上方；将通航孔提升栈桥的桥体框架分节段拼接于导梁的后端，并逐步向对岸方向推进；逐步拆除到达对岸的导梁；将桥体框架的两端分别就位于河道两岸的原栈桥的端部位置；安装提升架；在桥体框架上铺设桥面结构。本发明用以解决现有技术中在大跨径通航河道的上方架设提升栈桥难度较大的缺陷，实现一种简便高效的提升栈桥施工方案。
