Splayed inner diagonal bracing large-space light single-wall pouring jacket steel cofferdam and construction method
The lower end of a single-wall pouring jacket is arranged on a bearing platform bracket on the outer side of a pier column bearing platform, a sandbag is arranged for sealing the bottom, vertical stiffening ribs are arranged along the four walls of the single-wall pouring jacket at equal intervals, horizontal annular stiffening ribs are arranged on the inner sides of the vertical stiffening ribs, and the horizontal annular stiffening ribs are arranged on the outer side of the single-wall pouring jacket. The two ends of the L-shaped corner section and the two ends of the horizontal connecting section located on the lowermost layer are each provided with a fixing bracket, and the fixing brackets are installed on the top face of the pier column bearing platform. Splayed supports and inner diagonal supports are arranged on the inner sides of the horizontal annular stiffening ribs, one end of each inner diagonal support is fixed to the middle of the horizontal connecting section, and the other end of each inner diagonal support abuts against the exterior of the pier column. Meanwhile, the invention further discloses a construction method of the steel cofferdam for reconstruction and reinforcement of the underwater pier column. The steel cofferdam structure is specially used for underwater pier column transformation and reinforcement engineering, the construction efficiency is improved while the cost is saved, and more abundant operation space is provided for constructors.
本发明公开了一种对八字内对撑大空间轻型单壁套箱钢围堰，单壁套箱的下端置于墩柱承台外侧的承台牛腿上，设置有沙袋进行封底，竖向加劲肋沿着单壁套箱的四壁等距间隔设置，水平环向加劲肋在竖向加劲肋内侧设置，位于最下层的L型拐角段、水平连接段的两端各配备有一个固定牛腿，固定牛腿安装到墩柱承台的顶面；水平环向加劲肋的内侧设置有对八字撑和内对撑，每个内对撑的一端固定在水平连接段中部，另一端抵在墩柱外。同时，还公开了水下墩柱改造加固用钢围堰施工方法。专用于水下墩柱改造加固工程的钢围堰结构，在节约成本的同时，提高施工效率，并为施工人员提供更加充裕的作业空间。
