Dig down the exact meaning of Horizontal Directional Drilling
Horizontal directional drilling (HDD) is a trenchless construction method used to install pipes underground without disturbing the ground surface. The drill is launched from one end of the designed bore path and retrieved at the other end, and except for the launch and retrieving spaces above ground, the entire process takes place underground, out of sight. Horizontal Directional Drilling has become a choice alternative to conventional pipe-laying methods that require opening up the earth’s surface up to the depth of installation for the entire pipeline route. Horizontal directional drilling is ideal for use where trenching needs to be avoided such as under a railroad, an embankment, highway, and beneath lakes and rivers. With advanced HDD steering technology, it is also now possible to install pipelines under busy city streets without disrupting the flow of traffic and affecting businesses. History of Horizontal Directional Drilling HDD can be traced back to the early 1900s when...
