摘要
关角隧道在使用进口钻孔注浆设备C6钻机的过程中,为提高钻孔效率,对该钻机进行钻速试验,经过分析提出了提高钻孔速度的一些技巧和方法。施工实践表明,这些技巧和方法效果较好,经济效益显著。
This text introduced some successful construction experience in detail, during the Guanjiao tunnel grouting con- struction, to upgrade the imported C6 borer equipment working efficiency. After many tests and improvements, finally some crafts and measures are proposed to upgrade its drill speed. Practice shows that such crafts and measures yield good eco- nomic benefits.
