深水承台锁扣钢管桩围堰设计应用研究
|
摘要
为了对深水承台锁扣钢管桩围堰的设计应用进行研究分析,以某新建高速铁路桥梁工程为背景,选取锁扣钢管桩围堰和双壁钢围堰两种围堰方案,从可行性和经济性2个角度对2种围堰措施进行对比研究,结果表明:在深水承台下采用锁扣钢管桩围堰辅助施工是可行的,并且相对于双壁钢围堰具有更强的适用性;采用锁扣钢管桩围堰辅助施工将节约钢材量和混凝土量,并减少挖方量,具有良好的经济效益。
In order to study and analyze the design and application of the steel pipe pile cofferdam for deep water caps,a new high-speed railway bridge project is adopted as the background,and two cofferdam schemes of locked steel pipe pile cofferdam and double-wall steel cofferdam are selected. Comparing the two cofferdam measures from the two aspects of feasibility and economy,the results show that it is feasible to use the locking steel pipe pile cofferdam to assist the construction under the deep water platform,and compared with the double-wall steel cofferdam. It has stronger applicability;the use of lock steel pipe pile cofferdam to assist construction will save steel and concrete,and reduce the amount of excavation,which has good economic benefits.
