Method for erecting large-span steel structure gallery bridge by utilizing tidal range
The invention relates to a method for erecting a large-span steel structure gallery bridge by utilizing a tidal range, which belongs to the field of bridge construction. According to the method for erecting a large-span steel structure gallery bridge by utilizing the tidal range, the large-span steel structure gallery bridge is completely assembled and tailor-welded on a flat barge, the tide levelin tide water is utilized (the calculation height meets the barge draft depth), the barge is horizontally moved to a bridge pier left and right by using two tugs and rotates by 90 degrees when waiting for tide water to reach a high tide level (the calculation height ensures that the gallery bridge crosses surrounding obstacles), the gallery bridge is preliminarily erected at the position of a bridge pier, descends along with tide water and then is accurately positioned, a submersible pump is installed on the flat barge, the pump is started to pump water into the flat barge bin, separation ofa jig frame on the flat barge and the gallery bridge is accelerated, the barge drives the jig frame to move, and the gallery bridge is smoothly and successfully erected.
本发明涉及一种利用潮差实现大跨度钢结构廊桥的架设方法，属于桥梁施工领域。本发明所述的利用潮差实现大跨度钢结构廊桥的架设方法，大跨度钢结构廊桥在平板驳船上全部组装拼焊完成后，利用潮水中潮位（计算高度满足驳船吃水行深），用两条拖轮左右将驳船水平移位至桥墩处，等待潮水至高潮位（计算高度确保廊桥越过周围障碍）旋转90°，将廊桥初步架设到桥墩位置，随着潮水下降，再精确定位，在平板驳船上安装有潜水泵，打开泵向平板驳船仓内压水，加快平板驳船上胎架与廊桥的脱离，驳船带着胎架移位，廊桥顺利架设成功。
