Compared with the simultaneous operation of multiple drilling machines or the device with multiple drilling heads, the time spent will be greatly increased. At the same time, when the drill bit or drill rod is replaced, the single-arm drilling machine needs to stop operation, which increases the investment cost. In the construction process, horizontal directional drilling is a commonly used construction method when inclined holes need to be drilled.
