【摘要】 将传统的潜孔锤与凿岩机相结合,研制成潜孔锤孔底回转机构,这种新型的潜孔锤,不用钻机,只用空压机带动潜孔锤,可以实现冲击与回转,为我国大口径帷幕工程、水利水电工程及非开挖工程钻进效率的提高提供了新的工艺方法。更多还原

【Abstract】 a new rotary mechanism of the DTH hammer is developed, which is the combination of the traditional DTH hammer and the rock drill. This new DTH hammer, driven only by an air compressor rather than a drill rig, can produce percussive and rotary movements. It provides an innovative process of increasing the drilling efficiency in China’ s cur-tain engineering large-hole curtain engineering, hydraulic and hydropower engineering and trenchless engineering.更多还原
