Research on the Improvement Structure of Internal Drilling Machine

泵吸冲击反循环钻机及回转式泵吸反循环钻机产品的开发,在打井和桩基工程中起了重要作用,文中就此类产品结构如何进行改进,以适应基本建设基础施工工程迅猛发展的需要,进行了探讨。

The principle,characters, and its great use in well and stake project of the empolder percussive drilling are introduced. How to improve the structure of this product is adjusted to the need of the great development for construction basic engineering.
