深水裸岩桥桩基钴孔作业平台建造技术探讨

摘要

对深水裸岩条件下沉放轻型单壁钢套箱模板，水下灌筑混凝土固结钢管桩底建造桩基钻孔作业平台新技术进行介绍，该技术应用于湖南吉怀高速舞水河大桥施工中，效果良好，可为同类型桥梁施工提供借鉴。%The article introduces the new technology of placement of single-wall steel box for concrete formwork and underwater concrete pouring for consolidation of steel pipe foundation to build platform for pile foundation drilling in the situation of deep water and bare rock, such a new technique was successfully applied in Hunan Jihuai Highway Wushui River Bridge construction, which can provide experience and reference for similar construction in the future.
