摘要
本文比较系统地总结了目前国内采用反循钻进工艺施工基桩孔所出现的一些技术,并在此基础上提出了开发新型反循环钻进工艺装备的设想。按新的设计方案开发的反循环钻进工艺装备将会有效地提高钻进效率,并可适应硬岩和深孔施工的需要,建议有兴趣的厂家能够从事这方面的开发设计工作。
On the base of summary of the techniques in foundation pile hole by reverse circulation drilling in the country,an initial idea of developing new reverse circulation drilling technology and equipment is put forward in this paper. The new reverse circulation drilling technology and equipment in the design plan will greatly increase the drilling efficiency and suit to hard rock and deep drilling.
