Double-wall steel cofferdam structure construction method and double-wall steel cofferdam structure
The invention relates to a double-wall steel cofferdam structure construction method and a double-wall steel cofferdam structure. The double-wall steel cofferdam structure construction method comprises the following steps that a plurality of cofferdam structures are assembled on the land; wherein each cofferdam structure is annular, the bottom of one cofferdam structure is closed, the top of the cofferdam structure is open, and the tops and the bottoms of the remaining cofferdam structures are arranged in a penetrating mode; and a plurality of cofferdam structures are sequentially hoisted in the branch trestle, the cofferdam structures are arranged in a laminated mode, a welding seam between every two adjacent layers of cofferdam structures in the vertical direction is welded, and the welded cofferdam structures sink to the underwater ground. A traditional integral type double-wall steel cofferdam structure is layered in the height direction and can be assembled in a factory or on the land along the bank, and the integrity and the machining quality of the cofferdam are improved. In the construction process, only the welding seams between the two adjacent layers of cofferdam structures need to be welded, the multiple layers of welding seams are distributed in the height direction at intervals, a plurality of working faces and a large working space are provided, synchronous welding of the multiple sections of cofferdams is achieved, and the cofferdam assembling time is greatly shortened.
本发明涉及一种双壁钢围堰结构施工方法及其结构，其包括以下步骤：在陆地组装多个围堰结构；其中，每个围堰结构呈环形，其中一个围堰结构的底部呈封闭设置，且其顶部呈开口设置，剩余的围堰结构的顶部和底部贯通设置；在支栈桥的内部依次吊装多个围堰结构，使多个围堰结构叠层设置，并焊接相邻两层围堰结构在上下方向之间的焊缝，将焊接后的多个围堰结构下沉至水底地面。将传统整体式双壁钢围堰结构沿高度方向分层，可在工厂或沿岸陆地组装，有利于围堰的整体性及加工质量；在施工过程中，只需焊接相邻两层的围堰结构之间焊缝，且多层焊缝均为高度方向间隔分布，具备多个工作面和较大作业空间，实现多节围堰可同步施焊，极大缩短围堰拼装时间。
