地铁高架区间水中承台施工技术

Construction Technology for Foundation Pile Cap of Underwater in Subway Elevated Interval

水中承台钢板桩围堰钢内支撑施工,采用型钢组合拼装,提高了钢板桩围堰整体刚度及截面承载能力,施工便捷。某地铁工程高架区间,承台面位于水面以下,采用钢板桩围堰的方法进行施工,文中针对水中承台钢围堰施工工艺、控制重点及施工注意事项等进行介绍。

The construction of the foundation pile cap of underwater uses steel section combination in steel cofferdam and supporting technology,improves the bearing capacity and stiffness of steel cofferdam and be convenient for the construction.A subway elevated interval,pile cap surface is located below the water surface and for construction according to the method of steel cofferdam,the author introduces the construction process,control points and the matters that needs to pay attention of cofferdam for foundation pile cap of underwater.
