摘要：

叙述了哈尔滨至大连客运专线第二松花江特大桥主跨1083号、1084号水中墩采用的新型竖向分条双壁钢围堰施工的止水工艺,总结了新型钢围堰的止水施工技术。实践表明该项工艺的应用得到了较好的止水效果,具有较好的推广意义,为今后类似工程提供宝贵的施工经验。

This paper introduces the water stopping technology for a new type of double wall steel cofferdams with vertical splitting,which was successfully used for the construction of No.1083 and No.1084 in-water piers of the second super large bridge over the Songhuajiang River on Harbin-Dalian Passenger Railway Line.The water stopping technology for the new type of double wall steel cofferdams is summarized.It is proved that the application of the technology has produced effective wa-ter-stopping result and the technology has a good prospect for popularization.It may provide valuable engineering experiences for other similar projects in future.
