Single-wall double-chamber steel boxed cofferdam and construction method thereof
The invention discloses a single-wall double-chamber steel boxed cofferdam and a construction method thereof. The cofferdam is arranged on the periphery of the double-column pier and comprises a peripheral frame system, an internal supporting system and a bottom positioning system. The peripheral frame system comprises side plates, longitudinal reinforcing ribs, transverse reinforcing ribs and corner splicing pieces; the internal supporting system comprises I-shaped diagonal bracings, inclined bracings and pier column diagonal bracings; the bottom positioning system comprises a bearing platform and a positioning bracket. The single-wall double-chamber design is adopted, the bottom pier columns of the double-column type pier can be transformed and constructed at the same time, and the construction time is greatly saved. In addition, by means of the sectional type assembling method, the components have the characteristic of being capable of being recycled for multiple times, low carbon and environmental protection are achieved, and the construction cost is effectively reduced.
本发明公开了一种单壁双室钢套箱围堰及其施工方法。该围堰设置于双柱式桥墩的外周，包括外围框架体系、内部支撑体系和底部定位体系；所述外围框架体系包括侧板、纵向加强肋、横向加强肋和转角拼接件；所述内部支撑体系包括工字型对撑、斜撑和墩柱对撑；所述底部定位体系包括承台和定位牛腿。本发明整体采用单壁双室设计，可同时对双柱式桥墩的底部墩柱进行改造施工，大幅节约施工时间。此外，利用分段式组装方法，构件具有可多次循环使用的特性，低碳环保，有效地降低了建造费用。
