Steel cofferdam structure for deepwater foundation auxiliary construction and construction method of steel cofferdam structure
The invention relates to a steel cofferdam structure for deepwater foundation auxiliary construction and a construction method of the steel cofferdam structure. The method is suitable for the technical field of cofferdams. According to the technical scheme, the cofferdam comprises a plurality of corner connecting units and cofferdam wall bodies arranged between every two adjacent corner connecting units. The cofferdam wall body comprises at least one cofferdam unit, and the cofferdam unit is formed by splicing a plurality of hollow steel plates; a first limiting column is arranged on the right side face of the hollow steel plate, a first limiting clamping groove capable of being matched with the first limiting column is formed in the left side face of the hollow steel plate, and a sealing air bag matched with a gap between the first limiting clamping groove and the first limiting column is arranged in the first limiting clamping groove. The top of the hollow steel plate is provided with a top sealing structure, and the bottom of the hollow steel plate is provided with a bottom sealing structure matched with the top sealing structure to achieve sealing. At least one connecting seat is fixed on the inner side surface of the hollow steel plate; a supporting and fixing mechanism is arranged in the steel cofferdam structure and fixedly connected with the connecting bases of the hollow steel plates on the steel cofferdam structure.
本申请涉及一种用于深水基础辅助施工的钢围堰结构及其施工方法。适用于围堰技术领域。技术方案包括多个转角连接单元，以及设置于相邻两转角连接单元之间的围堰壁体；围堰壁体包括至少一个围堰单元，该围堰单元由若干空心钢板拼接而成；空心钢板右侧面上设有第一限位柱，空心钢板左侧面有能与第一限位柱配合的第一限位卡槽，该第一限位卡槽内设有与第一限位卡槽和第一限位柱之间间隙适配的密封气囊；空心钢板顶部设有顶部密封结构，空心钢板底部设有能与顶部密封结构配合实现密封的底部密封结构；空心钢板的内侧面上固定有至少一个连接座；钢围堰结构内部设有支撑固定机构，该支撑固定机构与钢围堰结构上各空心钢板的连接座固定连接。
