旋挖钻机在卵石地层施工中的应用

The application of rotary drilling rig on pebble formation construction

结合工程实践,介绍了旋挖钻机在卵石地层施工中应用时需注意的几个技术问题,包括钻机和钻头的选择、泥浆的制备等,并提出了旋挖钻机在卵石地层中施工时的注意事项,以指导旋挖钻机施工作业。

Combining with the engineering practice,this paper introduces several technical problems of rotating drill applications in the pebble formation construction needing to be taken attention of,including the rig and bit choice,the preparation of mud,puts forward some attention notes for the the rotating drill construction in pebble strata in order to guide the rotating drill construction work.
