摘要
该文结合某斜拉桥主墩承台的施工实践,介绍了采用锁口钢管桩围堰挡土止水施工的相关技术。重点介绍了该围堰相关的设计验算、结构布置、锁口钢管桩加工、锁口桩沉桩、围堰内除土、支撑安装、水下封底、抽水堵漏等,供类似桥梁施工时参考。
Combined with the construction practice of the main pier base slab of a cable-stayed bridge,the article introduces the relative construction technique of using die locked steel pipe pile cofferdam to retain the soil and stop the water,and focuses on introduction of the design checking computations,structure arrangement,processing of locked steel pipe pile,sinking of locked pile,soil removal in cofferdam,support installation,underwater back cover and pumping blocking up related to the cofferdam,which can be referred for the construction of the similar bridges.
