摘要
武汉天兴洲公铁两用长江大桥3号主塔墩双壁钢吊箱围堰集钢护筒插打定位、导向,钻孔作业平台,承台施工功能于一体,可根据施工水位依靠围堰自身浮力上下浮动。对该围堰的设计特点与设计方法进行介绍。
The double-wall steel boxed cofferdam for pylon pier No. 3 of Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge is designed to have all functions in one, including those of the positioning and guiding construction of setting and driving bored pile steel casings, a working platform for boring construction and the construction of pile cap. The cofferdam can be adjusted upward and downward by its own buoyant force in accordance with the required construction water levels. In this paper, the design features and design method of the cofferdam are described.
