浅谈旋挖钻机在各种复杂地层的施工技术

On construction technique of rotary drilling machine in all kinds of complicated layers

针对砂层、卵石层、泥岩层、硬质岩层等复杂地层,结合旋挖钻机的施工特点和秦皇岛地区的地质情况,总结了旋挖钻在复杂地层的施工技术,以指导实践。

Aiming at the complicated layers, such as the sand layer, the pebble bed, the layer of mud-stone, hardened sediment, the paper combining with the construction features of the rotary drilling machine and the geological situation in Qinhuangdao, sums up the rotary driller＇ s construction technique in complicated layers, so as to direct the practice.
