摘要
结合武汉青山长江公路大桥南主塔哑铃形承台施工支护结构,对大型桥梁基础施工中采用锁口钢管桩围堰施工的主要技术方案进行了阐述。实际结果表明,该方案总体可行,施工过程整体安全可控,围堰顺利渡过了2016年长江特大洪水。
Based on the construction support structure of the dumbbell bearing platform of the south main tower of Qingshan Yangtze River Highway Bridge in Wuhan,the main technical scheme of the locking steel pipe pile cofferdam for the construction of the large bridge foundationis expounded.The results show that the scheme is generally feasible,the safety of the overall construction is controlled,and the cofferdam successfully withstood the great flood of the Yangtze River in 2016.
