Steel cofferdam installation process
The invention provides a steel cofferdam installation process. The steel cofferdam installation process comprises the following steps: (1) assembling a first steel cofferdam section on a constructed water splicing platform, and hoisting and launching the first steel cofferdam section; (2) splicing a second steel cofferdam section and the first steel cofferdam section on the water surface, and transporting the first steel cofferdam section and the second steel cofferdam section to a cofferdam foundation pit in a floating mode by using a tug; (3) splicing a third steel cofferdam section to a fifth steel cofferdam section one by one on the second steel cofferdam section; and (4) accurately positioning the spliced steel cofferdam sections, and then injecting water to sink the steel cofferdam sections to the bottom of a cofferdam foundation pit. According to the steel cofferdam installation process, a floating transportation in-place installation and accurate positioning combined mode is adopted, so that the maximum deviation of the plane position of a steel cofferdam after implantation is only 10 cm, the effect is far beyond expectancy, and the steel cofferdam installation process hasthe advantages of being high in cofferdam in-place installation precision and remarkable in cost reduction benefit.
本发明提供了一种钢围堰安装工艺，包括：(1)在搭建的水上拼接平台上完成首节钢围堰的拼装，并将首节钢围堰吊装下水；(2)在水面上完成第二节钢围堰与首节钢围堰的拼接，采用拖轮将首节和第二节钢围堰浮运至围堰基坑就位；(3)在第二节钢围堰上逐一拼接第三至第五节钢围堰；(4)精确定位已拼接的钢围堰后注水下沉至围堰基槽的槽底。本发明采用浮运就位和精确定位相配合的方式，使钢围堰着床后平面位置最大偏差只有10cm，效果远超预期，具有围堰就位精度高、降本效益显著的优点。
