摘要
从施工方法及施工机械组合方面入手,并经过现场成桩试验,归纳总结出超厚砂层地质深水桥梁桩基反循环钻进+冲击钻接力成孔法成桩施工技术并在本项目得到了成功的应用,实现了快速成孔,有效缩短了施工工期、节约投资成本,可为以后类似深水基础地质条件提供借鉴。
The paper starts from the aspects of construction method and construction machinery combination,and passes the on-site pile forming test. The paper summarizes the pile forming construction technology of reverse circulation drilling + impact drilling relay hole forming method for deep-water bridge pile foundation in super thick sand layer geology, which has been successfully applied in the project, realizes rapid hole forming, effectively shortens the construction period and saves investment cost, which can provide reference for similar deep-water foundation geological conditions in future.
