Linear control method for steel box girder of cable-stayed suspension bridge
The invention belongs to the technical field of bridge construction, and particularly relates to a linear control method for a steel box girder of a cable-stayed suspension bridge, which comprises the following steps of: 1, anchoring and positioning a girder transporting ship, anchoring and positioning by utilizing the girder transporting ship, matching with tugs, and requiring the positioning deviation to be less than or equal to 50cm; according to the linear control method for the steel box girder of the cable-stayed suspension bridge, the first step, the second step, the third step and the fourth step are arranged, during use, the steel box girder of the cable-stayed suspension bridge is rapidly assembled and welded through the first step, the second step, the third step and the fourth step, and through an adjustable hoisting mechanism, the steel box girder is rapidly and horizontally adjusted when the steel box girder is hoisted, assembled and connected, so that the linear control of the steel box girder of the cable-stayed suspension bridge is achieved. It is ensured that the line shape of the steel box girder meets the construction requirement in the hoisting and assembling process, and therefore the problem that after an existing steel box girder is hoisted, horizontal adjusting and positioning cannot be conducted on the steel box girder, and assembling and welding construction of the steel box girder is difficult is solved.
本发明属于桥梁施工技术领域，尤其是一种斜拉悬索桥钢箱梁线形控制方法，包括以下步骤：步骤一、运梁船抛锚定位，利用运梁船抛锚定位，并用拖轮配合，要求定位偏差≤50cm。该斜拉悬索桥钢箱梁线形控制方法，通过设置步骤一到步骤四，在使用时，通过步骤一到步骤四实现对斜拉悬索桥钢箱梁进行快速拼装焊接，并通过可调起吊机构，在对钢箱梁进行吊装和拼装连接时，实现对钢箱梁进行快速水平调节，确保吊装和拼装过程中钢箱梁线形符合施工要求，从而解决了现有的钢箱梁起吊后，无法对钢箱梁进行水平调节定位，导致钢箱梁拼装焊接施工困难的问题。
