摘要
以石首长江公路大桥103号主墩钢板桩围堰封底施工为例,着重阐述了在超厚粉细砂地层条件下,采用水下不分散混凝土进行大面积钢板桩围堰封底施工技术,工程实践表明,此项施工技术能够确保工程的顺利实施,且效果良好。
Based on subsealing construction of steel sheet piling cofferdam of No. 103 main pier for Shishou Yangtze River Bridge project,this paper introduces underwater subsealing construction technology of steel cofferdam with large area in super thick sand stratum. Engineering practice shows that the construction technology can ensure the project smooth implementation,the effect is good.
