谈旋挖钻机在复杂地层中的应用

On application of rotary drilling rig in complicated strata

结合工程实例,从施工准备、施工工序及技术措施方面较全面的阐述了旋挖钻机在复杂地层钻孔灌注桩施工中的应用,根据地层性质调整钻机的操作方式,及时更换合适的钻具,以取得良好的施工效果。

Combining with the engineering example, the paper illustrates the application of the rotary drilling rig in the bored pile project with complicated strata from the construction preparation, the construction procedure and the technical measures, and indicates the operation way of the drilling machine should be adjusted and the drilling tools can be altered according to the features of the strata, so it aehieved better construction effect.
