摘　　要：钢吊箱围堰的下放入水是深水基础大桥施工中的技术难点。结合工程实例,介绍了利用千斤顶结合精轧螺纹钢吊杆下放钢吊箱围堰的技术、千斤顶及精轧螺纹钢吊杆的选用、下放步骤,并与其他几种下放钢吊箱围堰的技术进行了经济技术指标比较,可供类似深水钢吊箱围堰的下放借鉴。It is a technical difficulty in the construction of deep-water foundation bridge to put steel cofferdam into water. Combined with the engineering example,this paper introduces the technology of lowering the cofferdam with the combination of the jack and the fine steel threaded suspender,the selection and steps of the jack and the fine steel threaded suspender,and compares the economic and technical indexes with other techniques of lowering the cofferdam,which can be used for reference for the similar lowering of the cofferdam in deep water.
