结合境外工程现场实际情况,将JK-8冲击钻钻头改装成圆筒形锤头进行钢管嵌岩斜桩的成孔,打破了嵌岩斜桩只能由顶置式回转钻机或立轴式回转钻机施工的固定模式。该工法适应性好,安全系数高,具有推广价值。
結閤境外工程現場實際情況,將JK-8遲擊鑽鑽頭改裝成圓筒形錘頭進行鋼管嵌巖斜樁的成孔,打破瞭嵌巖斜樁隻能由頂置式迴轉鑽機或立軸式迴轉鑽機施工的固定模式。該工法適應性好,安全繫數高,具有推廣價值。

Combined with the practical situation of overseas projects, we changed the JK-8 impact drill bit into a tubular type impact hammer to drilling the steel pipe rock-socketed pile. This technology has broken the fixed pattern of batter pile con-struction using overhead type slewing drilling machine or vertical shafts slewing drilling machine only. The technology has good adaptability, high safety, and promotional value.
