horizontal directional drill
The horizontal directional drilling (HDD) technology is a kind of contemporary drilling technology which can be used to install underground utilities without having to dig trenches. Its most important thing was to bore underground, horizontally from the surface.That has earned it a place among the most efficient means for any terrain project are these days.The drive equipment enabled the machine to bore horizontally, so that underground pipelines or other facilities could be installed with a minimum of disruption to surface life.HTHD equipment are equipped with a variety of technological features, including steerable drilling heads, real-time tracking systems and push-pull power capable of precision installation applications. In the trenchless urban construction and environmentally sensitive areas where it is impractical to use traditional methods more and more common sights are these tunnelings.A common application is in trenchless construction in urban environments. It is also used to cross rivers or other obstacles where traditional methods are either impractical—polluting the environment, or impossible—by nature.
