为利用GSD—II型钻机实施贯通式潜孔锤反循环连续取芯(样)钻进工艺,对该钻机动力头的主轴结构进行了改进,设计了与之配套的专用反循环水龙头。本文介绍了所设计的反循环水龙头的结构组成及其现场使用情况。
In order to put the technique of coring continually by reverse circulation with hollowthrough DTH hammer in to practice with the GSD-Ⅱ drill, the shaft of GSD- Ⅱ drill＇ s motor head is improved. The special reverse circulation swivel that matches with the improved shaft is developed. The construction and application of the swivel are introduced in this paper.
