摘　　要：针对云和县龙泉溪云和段综合治理工程钻孔灌注桩施工中的困难,开展了技术攻关和工艺创新,运用水上浮式平台技术、浮球检测工艺、水上混凝土运输浇筑技术等,有效解决了倾斜岩面河床上钻孔灌注嵌岩桩施工的各项难题,为同类工程提供技术参考和借鉴。Based on the comprehensive management project of the Yunhe section of Longquan Stream in Yunhe County,a targeted technical research and innovation were carried out to solve the difficulties encountered during the construction of drilled cast-in-place piles.By employing floating platform technology,buoyancy detection process,and waterborne concrete transportation and pouring techniques,various challenges in the construction of drilled cast-in-place piles embedded in the inclined rock riverbed were effectively addressed.This provides technical references and insights for similar construction projects.
