Construction method of bridge closure section
The invention provides a construction method of a bridge closure section, which comprises the following steps that a cable crane is moved to a hoisting position in a no-load manner, and a transport ship transports a beam section to a position below the hoisting position; the secondary closure section is lifted to the position higher than the designed elevation through a cable loading crane, the traction system is used for pulling the secondary closure section to swing towards the side span side so as to be close to the side span beam section, and the secondary closure section is connected with a sling and is temporarily connected with the adjacent beam section; after installation of other secondary closure sections is completed, the cable loading crane lifts the main closure section from the transport ship to the position flush with the installed beam section, and the main closure section is connected with a permanent sling; and a three-way adjusting device is installed at the top of the transition pier, the position of the side span beam section adjusted through the three-way adjusting device is connected with the closure section on a construction site, and therefore closure of the bridge is completed. The main cable of the suspension bridge is matched with the cable loading crane and the winch to complete bridge closure, the construction efficiency is high, temporary supporting is not needed, and construction of supports on a construction site is reduced.
本申请提供一种桥梁合龙段的施工方法，其包括以下步骤：缆载吊机空载移动至起吊位，运输船将梁段运输至起吊位下方；通过缆载吊机先将次合龙段提升站至高于设计标高的位置，利用牵引系统起牵引该次合龙段朝向边跨侧荡移以与边跨梁段靠拢，次合龙段连接吊索并与相邻梁段临时连接；完成其他次合龙段的安装后，缆载吊机从运输船上起吊主合龙段至与已安装梁段齐平的位置，主合龙段连接永久吊索；在过渡墩墩顶安装三向调节装置，利用所述三向调节装置调节的边跨梁段的位置再与合龙段进行工地连接，以完成桥梁的合龙。本申请借助悬索桥的主缆配合缆载吊机和卷扬机来完成桥梁合龙，施工效率高，无需依靠临时支撑，减少施工现场支架的搭建。
