CH-50型工程地质钻机是适合于钻进第四系覆盖层的一种自行式钻机,在土层中冲击钻进效果很好,速度快,土层原状性保持好;但对于岩石(特别是坚硬岩石),因无法对钻具稳定加压,实际上几乎不能进行钻进。
The CH-50 engineering geological drilling rig is a self-propelled drilling rig suitable for drilling into the Quaternary covering layer. The impact drilling in the soil layer is very effective and the speed is fast. The original layer of the soil is well maintained; but for rock (especially It is hard rock, and it is practically impossible to drill because it is impossible to stabilize the drilling tool.
