摘要
水东湾大桥主塔承台为高桩承台,哑铃形结构,钢吊箱作为承台施工时的挡水和模板结构,是目前水中围堰工程的主要施工技术之一,在大型桥梁承台施工中应用广泛。本工程主塔承台采用单壁钢吊箱施工,钢吊箱工厂分块制作、试拼,运输至现场组合拼装,采用连续千斤顶同步下放,水下封底,形成承台干施工作业环境。
The main tower cap of Shuidongwan Bridge is a high-pile cap with dumbbell-shaped structure.Steel suspension box is one of the main construction techniques of underwater cofferdam project,which is widely used in the construction of large bridge caps. The main tower cap of this project is constructed with single-wall steel suspension box. The steel suspension box factory is made in blocks and assembled in trial. The steel suspension box factory is transported to the field and assembled in combination. The continuous jack is synchronously lowered and the underwater bottom is sealed to form the working environment for dry construction of the cap.
