旋挖钻进技术适用性的初步研究

The Study on Applicability of Rotary Drilling Technique

摘要:

在分析旋挖钻进技术适应性国内外研究现状的基础上，通过大量工程实例以及现场实践，以目前应用最多的正反循环钻进技术做为对比，研究了旋挖钻进技术的适用性，包括施工效率、施工质量、适用范围等。并对不同情况下两种施工方法的选择以及优化组合提出了建议。

Abstract:

Based on the status analysis on applicability of rotary drilling technique in home and abroad, through amount of engineering examples and spot practice, the author researched the applicability of rotary drilling technique and compared to normal & reverse circulation drilling. It includes construction efficiency, construction quality, applicability range, et al. In the last, the author suggested that optimum combination of the two costructuion methods should be applied in especial projects construction.
