摘要
详细阐述了旋挖钻机工艺性能及关键控制。在实际工程中,旋挖钻机在粘土、淤泥质土、人工回填土及含部分卵石、碎石等地层的钻进效率明显高于冲击钻机成孔。旋挖钻在可施工的地质条件下,可极大地提高施工效率,且不大幅增加成孔费用。
Here,the performance and critical control techniques of rotary drilling rig are elaborated in detail.In actual projects,the construction efficiency of the rotary drilling rig is significantly higher than the percussion drilling rig in the clay layer,silty soil layer,artificial backfill layer and some pebbles,gravel layer,etc.
