深水裸岩高桩承台钢吊箱设计与施工

DESIGN AND CONSTRUCTION OF STEEL HOISTING BOXES OF BEARING PLATFORMS WITH HIGH PILES IN DEEP WATER AND UNCOVERED ROCK

以柳州市三门江大桥高桩承台施工为例,介绍拉压柱式钢吊箱围堰的设计与施工,从钢吊箱围堰的设计方案、工作原理、施工工艺及施工要点等方面,对钢吊箱围堰施工中的注意事项进行了阐述。工程实践表明,该钢吊箱设计合理,能满足工程的需要,对同类承台施工有一定的借鉴意义。

The construction of bearing platforms with high piles for Sanmenjiang Bridge in Liuzhou being taken as an example, it introduces design and construction of steel hoisting box cofferdams with tensile and compressive columns, including design scheme, work principle, construction technology, and construction gist of steel hoisting box cofferdams as well as the problems to be noticed in the construction. Engineering practice proves that the box is a reasonable design that can satisfy the requirement of engineering, offering a reference to the construction of similar platforms.
