摘要
比较嵌岩钻进几种方法的特点 ,重点介绍了以双绳同步卷扬为核心部件的重锤式冲击反循环钻进技术的应用 ,拓展传统冲击钻和转盘钻机对地层的适应性 ,通过不同类型的钻具和工艺组合 ,以满足不同地层或不同类型槽孔对钻机的要求。
The paper compares the characteristics of the several drill technical methods to dig the large diameter piling embedded rock. The percussive reverse circulation drill with double synchronous hoist is described particularly. The adaptability to drilling layer is broadened while the conventional percussive or rotary table rig is combined with the percussive reverse circulation drill.
