浅谈旋挖钻的优点及在特殊地层所发挥的优势

On the advantages of rotary drilling and drilling stratigraphic plays in the special advantages

文章通过对旋挖钻与传统钻,在性能、工艺上进行了对比,旋挖钻因其施工速度快、成孔质量高、环境污染小、操作灵活方便、安全性能高、适用性强及在特殊地层下工作等诸多优势,成为工程界钻孔桩施工的主要成孔设备。因此,研究、探讨旋挖钻施工技术,具有十分重要的意义。

The paper based on the drilled with conventional rotary drilling drilling, in terms of performance, technology compared, because of their construction drilling rotary drilling speed and hole quality, environmental pollution, operational flexibility, security, high-performance, applicability, and in the formation of special work and many other advantages, as a bored pile construction engineering major hole equipment.Therefore, a study to examine the construction of rotary drilling drilling technology, is undoubtedly of great significance.
