摘要
文章结合清江市政特大桥EPC工程总承包项目2#主塔锁扣钢管桩围堰快速施工的实际情况及施工特点,介绍了城区跨江斜拉桥临水钢围堰高效施工技术。为保证钢围堰质量,确保施工安全,缩短施工周期,降低施工成本,最终确定采用冲击钻结合旋挖钻引孔施工技术,该技术可供类似工程借鉴。
Based on the actual situation and construction characteristics of the rapid construction of the 2# main tower lock buckle steel pipe pile cofferdam of the EPC project of Qingjiang Municipal Bridge,this paper introduces the efficient construction technology of the water-facing steel cofferdam for urban river-crossing cable-stayed bridge.In order to ensure the quality of steel cofferdam,ensure the construction safety,shorten the construction period and reduce the construction cost,the guide hole construction technology of impact drill combined with rotary drill is finally determined,which can be used for reference in similar engineering.
