摘要
介绍了泵吸反循环在百米深大直径钻孔灌注桩成孔过程中循环液反循环实现条件 ,运行工况参数之间的相互关系 ,并通过工程实践 。
In this article,the author introduces some application situations of the pump-exsuction reverse circulation technology in pore-forming process of one hundred meters deep large diameter drilled grouting piles such as realization conditions for reverse circulation of circulation liquid, and relevant relationships of operation condition parameters and so forth. This technology has been testified by practical projects and had good drilling effects.
